3 5000 Years of World System History: The Cumulation of Accumulation Barry K. Gills and Andre Gunder Frank INTRODUCTORY SUMMARY We argue that the main features of the economic and interstate world system already analyzed by Wallerstein (l974) and Modelski (l987) for the "modern" world system, and for earlier ones by Chase-Dunn (l986, l989) and others, and in this book by Chase-Dunn and Hall (Chapter 1) and Wilkinson (Chapter 4 and also 1987) also characterize the development of this same world system in medieval and ancient times, indeed for at least the past five millennia. These features are 1) the historical continuity and development of a single world economy and inter-polity system; 2) capital accumulation, technological progress, and ecological adaptation/degradation as the principal motor forces in the world system; 3) the hierarchical center-periphery political economic structure of the world system; 4) alternate periods of political economic hegemony and rivalry (and war) in the world system; 5) and long political economic cycles of growth/accumulation, center/periphery positions, hegemony/rivalry, etc. Our study of the unequal structure and uneven dynamic of this world system is based, like a three legged stool, on economic, political, and cultural analysis. This essay covers the following topics and advances the following theses, beginning with the most concrete historical ones and going on to progressively more abstract theoretical ones. I. WORLD SYSTEM ORIGINS 1. The origins of our present world system (WS) can and should be traced back at least 5000 years to the relations between Mesopotamia and Egypt. 2. The ecological basis of the WS accounts for its origins and much of its subsequent historical development. 3. Economic connections among various parts of the WS began much earlier and have been much more prevalent and significant than is often realized. 4. World system extension grew to include most of the Asio-Afro- European ecumenical ("Eastern" hemisphere) landmass and its outlying islands by 600 BC and incorporated much of the "Western" "New World" by 1500 AD, although there is increasing evidence of earlier contacts between them. II. WORLD SYSTEM ROUTES AND NEXUSES 1. Maritime routes furthered economic and other connections among many parts of the WS and contributed to its expansion in important ways. 2. The Silk Roads, over both land and maritime routes, formed a sort of spinal column and rib cage of the body of this WS for over 2000 years. 3. Central Asia has been a much neglected focal point of WS history both as a logistic nexus among its regions to the East, South and West and through the recurrent pulse of its own waves of migration and invasion into these regions. 4. The Three Corridors and Logistic Nexuses in what is now called the "Middle East," "Inner Asia," and some sea straits have always played especially significant bottle-neck choke-point roles in the development of the WS. III. INFRASTRUCTURAL INVESTMENT, TECHNOLOGY AND ECOLOGY 1. Infrastructural investment accompanied and supported most parts of the WS from its beginning and throughout its historical development. 2. Technological innovation also played a similar and related role throughout the historical development of the WS and mediated in the competitive economic and military conflicts among its parts. 3. Ecology, however, always and still exercises an essential influence and constraint on this WS development. IV. SURPLUS TRANSFER AND ACCUMULATION RELATIONS 1. Surplus transfer and interpenetrating accumulation among parts of the WS are its essential defining characteristics. This transfer means that no part of the WS would be as it was and is without its relations with other parts and the whole. 2. Center-Periphery-Hinterland (CPH) complexes and hierarchies among different peoples, regions and classes have always been an important part of WS structure. However, the occupancy of musical chair places within this structure has frequently changed and contributed to the dynamics of WS historical development. 3. "Barbarian" nomad - sedentary "civilization" relations have long been and continue to be especially significant and neglected aspects of CPH structure and WS development. V. POLITICAL ECONOMIC MODES OF ACCUMULATION 1. Modes of accumulation, more than modes of production, are the essential institutional forms and variations of WS historical development; but they are not only localized or regional. 2. Transitions in modes of accumulation are not unidirectional in WS history and development. 3. Public/private accumulation are both collaborative and conflicting institutional forms and mixes of investment and accumulation. 4. Economy/polity contradictions characterize the WS throughout its history in that economic organization is much wider and WS wide, while political state and even imperial organization is much more local and regional. VI. HEGEMONY AND SUPER-HEGEMONY 1. Hegemony is the political and economic (and sometimes also cultural) domination of peoples and regions in parts of the WS, which is based on the centralization of accumulation in the same. 2. Cycles of accumulation and hegemony are causally interrelated and characterize the development of the WS throughout its history. 3. Super-hegemony is the extension of hegemony or the hierarchical ordering of primus inter pares hegemonies to centralize accumulation on a WS level. Super-hegemony has been acknowledged for part of the 19th and 20th centuries, but may already have occurred earlier as well. 4. Cumulation of Accumulation is the culminating synthesis of the ecological, economic, technological, political, social, and cultural structures and processes in WS history. VII. A HISTORICAL MATERIALIST POLITICAL ECONOMY AND RESEARCH AGENDA 1. Historical materialist political economic summary conclusions are drawn from the foregoing arguments. 2. Political, economic and cultural three legged stools characterize the WS through the interrelations and mutual support of all three aspects of social history. Therefore, any historical materialist political economy of the WS must incorporate all three. 3. Analytic and research agendas on the structure and dynamics of WS history over 5000 or more years must search for more system wide characteristics, changes, perhaps even cycles, and development. I. WORLD SYSTEM ORIGINS 1. The Origins The designation in time of the origin of the world system depends very much on what concept of system is employed. We may illustrate this problem by analogy with the origins of a major river system. For instance, look at the Missouri-Mississippi river system. In one sense, each major branch has its own origin. Yet the Mississippi River can be said to have a later derivative origin where the two major branches join together, near St. Louis, Missouri. By convention, the river is called "The Mississippi" and it is said to originate in Minnesota. Yet the larger and longer branch is called "the Missouri," which originates in the Rocky Mountains in Montana. Of course, all of these also have other larger and smaller inflows, each with their own point(s) of origin. The problem is how to set a fixed point of origin when in fact no such single point of origin exists for the river system as a whole. In the case of the world system it would be possible to place its origins far up stream in the Neolithic period. However, it may be more appropriate to discuss the origins further down stream, where major branches converge. By the river system analogy, we may identify the separate origins of Sumer, Egypt, and the Indus as sometime in the fourth to the third millenniums BC. The world system begins with their later confluence. David Wilkinson (1989) dates the birth of "Central Civilization," through the political - conflictual confluence of Mesopotamia and Egypt into one over-arching states system, at around 1500 BC. Wilkinson's work is of very great value to the analysis of world system history. Essentially, the confluence of "Mesopotamia" and "Egypt" gave birth to the world system. However, by the criteria of defining systemic relations, spelled out below, the confluence occurs considerably earlier than 1500 BC. By economic criteria of "inter-penetrating accumulation," the confluence included the Indus valley and the area of Syria and the Levant. Thus, the confluence occurred sometime in the early or mid third millennium BC, that is by about 2700-2400 BC. 2. The Ecological Basis Historical materialist political economy begins with the recognition that "getting a living" is the ultimate basis of human social organization. The ultimate basis of "getting a living" is ecological however. The invention of agriculture made possible the production of a substantial surplus. Gordon Childe (1951) made famous the term "Neolithic Revolution" to describe the profound effects on human social organization brought about by the production of an agricultural surplus. The subsequent "Urban Revolution" and the states that developed on this basis contributed to the formation of our world system. From the outset, this social organization had an economic imperative based on a new type of relationship with the environment. The alluvial plains of Egypt, Mesopotamia and Indus are similar in that their rich water supply and fertile soil makes possible the production of a large agricultural surplus when the factors of production are properly organized. However, all three areas were deficient in many natural resources, such as timber, stone, and certain metals. Therefore, they had an ecologically founded economic imperative to acquire certain natural resources from outside their own ecological niches in order to "complete" their own production cycles. Urban civilization and the state required the maintenance of a complex division of labor, a political apparatus, and a much larger trade or economic nexus than that under the direct control of the state. Thus, the ecological origins of the world system point to the inherent instability of the urban civilizations and the states from which it emerged. This instability was both ecological - economic and strategic. Moreover, the two were intertwined from the beginning. Economic and strategic instability and insecurity led to efforts to provide for the perpetual acquisition of all necessary natural resources, even if the required long distance trade routes were outside the direct political control of the state. This was only possible through manipulated trade and through the assertion of direct political controls over the areas of supply. The internal demographic stability, and/or demographic expansion, of the first urban centers depended upon such secure acquisition of natural resources. However, in a field of action in which many centers are expanding simultaneously, there must come a point when their spheres of influence become contiguous, and then overlap. As the economic nexus of the first urban civilizations and states expanded and deepened, competition and conflict over control of strategic sources of materials and over the routes by which they were acquired tended to intensify. For example, control over certain metals was crucial to attaining technological and military superiority vis a vis contemporary rivals. Failure to emulate the most advanced technology constituted, then as now, a strategic default. The ultimate rationale for the origins of the world system were thus embedded in the economic imperative of the urban based states. A larger and larger economic nexus was built up. Specialization within the complex division of labor deepened, while the entire nexus expanded territorially "outward." In the process, more and more ecological niches were assimilated into one interdependent economic system. Thereby, the world system destroyed and assimilated self-reliant cultures in its wake. By the third millennium BC, the Asio-Afro-European economic nexus, upon which the world system was based, was already well established. Thereafter, the constant shifts in position among metropoles in the world system cannot be properly understood without analysis of the ecological and technological factors "compelling" certain lines of action. The rise and decline of urban centers and states can be made more understandable by placing them within the world systemic context. This also involves paying attention to their role in the economic nexus, particularly with regard to the sources and supply of key commodities and natural resources. The logic of the political structure of the world system is one in which the security of the member states, and their ability to accumulate surplus, is perpetually vulnerable to disruption. This situation created a dynamic of perpetual rivalry. Thus, attempts are made to extend political control over strategic areas of supply in the overall economic nexus. 3. Economic Connections New historical evidence suggests that economic connections through trade and migration, as well as through pillage and conquest, have been much more prevalent and much wider in scope than was previously recognized. They have also gone much farther back through world history than is generally admitted. By the same token, manufacturing, transport, commercial and other service activities are also older and more widespread than often suggested. The long history and systemic nature of these economic connections have not received nearly as much attention as they merit (Adams 1943). Even more neglected have been these trade connections' far reaching importance in the social, political, and cultural life of "societies" and their relations with each other in the world system as a whole. Even those who do study trade connections, as for instance Philip Curtin's (l984) work on cross-cultural trade diasporas, often neglect systematic study of the world systemic complex of these trade connections. Historical evidence to date indicates that economic contacts in the Middle East ranged over a very large area even several thousand years before the first urban states appeared. The Anatolian settlement Catal Huyuk is often cited as an example of a community with long distance trade connections some seven or eight thousand years ago. Jericho is another often cited example. Trade or economic connections between Egypt and Mesopotamia were apparently somewhat intermittent before 3000 BC, and therefore possibly not systemic. However, both Egypt and Mesopotamia very early on developed economic connections with Syria and the Levant, which formed a connecting corridor between the two major zones. The putative first pharaoh of unified Egypt, Narmer, may have had economic connections to the Levant. Certainly by 2700 BC, Egypt had formal political and economic relations with the city of Byblos on the Levantine coast. Byblos is probably the earliest port of economic contact mentioned in both Egyptian and Mesopotamian historical sources. For both Egypt and Mesopotamia, war and trade with Syria and the Levant involved the search for access to strategic and other materials, such as timber, metals, oils, and certain luxury consumption goods. The apparent goal of Akkadian imperial expansion was to gain the benefits of putting all of the most strategic routes in one vast corridor from the Mediterranean to the Persian Gulf under its sole control. There is evidence that Akkad maintained maritime economic connections with the Indus, known as "Meluhha," via ports in the Persian Gulf. Thus, Akkad consolidated a privileged position in the overall economic nexus. The city states of Syria and the Levant became the objects of intense rivalry between Egypt and Mesopotamia. Oscillation occurred in the control of these areas: from the first and second dynasties of Egypt, over to Akkad, then to the third dynasty of Ur. By the nineteenth century BC, Egypt again exercised influence over most of the Levant as vassal states. It is clear that throughout a considerable historical period, even to the time of the Assyrian and then the Persian empires, Syria and the Levant played a crucial role as logistical inter-linkage zones and entrepots within the world system. They linked the Mesopotamian, Egyptian, and Indus zones in one world system. 4. World System Extension Accumulation is a major incentive for, and the ultimate cause of, economic, political, and military expansion by and inter-linkage within the world system. Therefore, the process of accumulation and its expansion is also importantly related to the extension of the boundaries of the world system. Two additional analogies of expansion may be useful to understand the process: the glacier analogy and the ink blot analogy. By analogy to a glacier, the world system expanded along a course of its own making, in part adapting to pre-existing topology and in part itself restructuring this topology. By analogy to an ink blot, the world system also spread outward, beyond its area of early confluence. Probably the most spectacular single instance of this expansion was the "discovery" of the New World and later Oceania. David Wilkinson (1987) also sees Central Civilization as expanding into other areas and societies and incorporating them into itself. In one sense, the process is one of simple incorporation of previously unincorporated areas, on analogy with the expansion of an ink blot. However, the incorporation of some regions into the world system also involved processes more like merger than mere assimilation, as when two expanding ink blots merge. For instance, the incorporation of India, and especially of China, appear to be more merger than assimilation. Mesopotamian trade with the Indus was apparently well established at the time of the Akkadian empire. Repeated evidence of economic contact with India exists, though with significant periods of intermittent disruption. These disruptions make it difficult to set a firm date for the merger of India with the world system. Chinese urban centers and states appear to have developed essentially autonomously in the archaic Shang period. However, the overland routes to the central world system to the west were already opened by the end of the second millennium BC, particularly as migratory routes for peoples of Central and Inner Asia. The actual historical merger of Chinese complexes into the world system comes only after state formation in China reached a more advanced stage, in the late Zhou period. A series of loose hegemons began with Duke Huan of Qi (685-643 BC) and a process of unification of smaller feudatories into larger territorial states occurred. According to Wolfram Eberhard (1977), the eventual victory of the state of Qin and the creation of the first centralized empire in China was influenced by Qin's strong trade relations with Central Asia. These economic connections allowed Qin to accumulate considerable profit from trade. The Wei and Tao valleys of the Qin state were "the only means of transit from east to west. All traffic from and to Central Asia had to take this route" (Eberhard, 1977 p.60). The maintenance of maritime and overland trade routes, and the peoples located in the areas between major zones, play key logistical interlinkage roles in the process of merger. In the formation of the world system, the interaction of high civilization with tribal peoples, especially in Inner and Central Asia, but also in Arabia and Africa, played a crucial but largely neglected role, to which we shall return below. II. WORLD SYSTEM ROUTES AND NEXUSES 1. Maritime Routes The advertising blurb of the just published The Sea-Craft of Prehistory by Paul Johnstone (1989) reads "the nautical dimension of prehistory has not received the attention it deserves.... Recent research has shown that man travelled and tracked over greater distances and at a much earlier date than has previously been thought possible. Some of these facts can be explained by man's mastery of water transport from earliest times." Generally the sea routes were cheaper and favored over the overland ones. Some particularly important maritime routes are discussed below. 2. The Silk Roads The Silk Roads formed a sort of spinal column and rib cage - or more analogously perhaps, the circulatory system - of the body of this world system for some 2000 years before 1500 AD. These "roads" extended overland between China, through Inner and Central Asia, to the "Middle East" (West Asia). From there, they extended through the Mediterranean into Africa and Europe. However, this overland complex was also connected by numerous maritime silk "road" stretches through the Mediterranean, Black Sea, Red Sea, Persian Gulf, and along many rivers. Moreover, the predominantly overland Silk Road complex was complemented by a vast maritime Silk Road network centered on the Indian Ocean through the Arabian Sea and Bay of Bengal, and on the South China Sea. These maritime Silk Roads in turn were connected by overland portage across the Kra isthmus on the Malay Peninsula, as well as by ship through the Malaccan Straits between it and Sumatra, etc. The Silk Roads of course derive their name from China's principal export product to the West. However, the trade of items and peoples extended far beyond silk alone. Indeed, the silk had to be paid for and complemented by a large variety of other staple and luxury goods, money and services, including enslaved and other people who performed them. Thus, the Silk Roads also served as the trade routes, urban and administrative centers, and military, political, and cultural sinews of a vast and complex division of labor and cultural diffusion. 3. Central Asia If one looks at a map of Eurasia, it becomes clear that Central Asia (in present Afghanistan and Soviet Central Asia) was well positioned to act as the ultimate nodal center. Central Asia was the crossroads of a world system in which China, India, Persia, Mesopotamia, the Levant and the Mediterranean basin all participated. For instance, Central Asia played a key role in the joint participation in the world system of Han China, Gupta India, Parthian Persia and the Roman empire. However, Central and Inner Asia were also more than the meeting points of others. Inner and Central Asia also originated their own cycles of outward invasory/migratory movements in all directions. These cycles lasted an average of approximately two centuries and occurred in roughly half millennium intervals. For instance, there were waves of invasions from 1700-1500 BC, 1200-1000 BC, around 500 BC, around 0, from 400-600 AD and 1000-1200/1300 AD. Each inner wave pushed out outer waves, except the last one of Chinggis Khan and his successors to Tamerlane after him, who overran all themselves. Whether or not all these invasions responded to climatic changes, presumably they were both cause and effect of changes in rates of demographic growth and decline, which may in turn have climatic causes. However, they were also caused by - and in turn had effects on - the ecological, socioeconomic and political relations with their civilized neighbors. Thus, Inner and Central Asia and its pulse require special attention in world system history. How central was Central Asia to world system history? To what extent was Central Asia, and not primarily the other civilized areas, something of a motor force of change in the whole system? How was the rise and decline of various cities (Samarkand!) and states in this area related to system wide developments in trade? The place and role of Central Asia is as important as it is neglected. The entire development of the world system has been profoundly affected by the successive waves of invasion from the Eurasian steppes on the perimeter of the agro-industrial zones. This "system implosion" is such a major phenomenon that it cries out for systemic study and explanation. These system implosions were not deus ex machina, but integral to the overall developmental logic of the world system's expansionary trajectory. In particular, the invasions and migrations from Inner and Central Asia were always instrumental in transforming the economic, social, political and cultural life of their neighboring civilizations - and in forming their racial and ethnic complexions. Nor has the enormously important role of Central Asia as an intermediary zone in the world system received the systematic analysis which its functions merit. Other nomadic and tribal peoples, for instance on the Arabian Peninsula before Mohammed and in much of Africa, also participated in world system history and world accumulation in ways which have not been acknowledged except by very few specialists. 4. The Three Corridors and Logistic Nexuses Three magnets of attraction for political economic expansion stand out. One is sources of human (labor) and/or material inputs (land, water, raw materials, precious metal, etc.) and technological inputs into the process of accumulation. The second is markets to dispose of one zone's surplus production to exchange for more inputs, and to capture stored value. The third, and perhaps most significant, are the most privileged nexuses or logistical corridors of inter-zonal trade. Bottleneck control over the supply routes of raw materials, especially of metals and other strategic materials, plays a key role in attracting powers to such areas. This may also provide a basis upon which to make a bid for expansion of imperial power. Especially here, economic, political and military conflict and/or cultural, "civilizational," religious and ideological influence all offer special advantages. That is, special advantages for tapping into the accumulation and the system of exploitation of other zones in benefit of one's own accumulation. Therefore, it is not mere historical coincidence that these three nexus areas have recurrently been the fulcra of rivalry, commerce, and of religious and other cultural forms of diffusion. Certain strategically placed regions and corridors have played such especially important roles in world system development. They have been magnets which attracted the attention of expansionist powers and also of migrants and invaders. Major currents of thought also migrated through them. This attention is based on their role in the transfer of surplus within the world system, without which the world system does not exist. Certain metropoles have become attractive in and of themselves due to their positions along trade corridors, the growth of a market within the metropolitan city, and the accumulated wealth of the metropole itself. The rise and fall of great regional metropolitan centers and their "succession" reflects extra-regional changes in which they participate. For example, the succession of metropoles in Egypt from Memphis to Alexandria to Cairo reflects fundamental underlying shifts in world system structure. So does the succession in Mesopotamia from Babylon to Seleucia to Baghdad. Three nexus corridors have played a particularly pivotal and central logistical interlinkage role in the development of the world system. 1. The Nile - Red Sea corridor (with canal or overland connections between them and to the Mediterranean Sea, and open access to the Indian Ocean and beyond). 2. The Syria - Mesopotamia - Persian Gulf corridor (with overland routes linking the Mediterranean coast through Syria, on via the Orontes, Euphrates and Tigris rivers, to the Persian Gulf, which gives open access to the Indian Ocean and beyond). This nexus also offered connections to overland routes to Central Asia. 3. The Aegean - Black Sea - Central Asia corridor (connecting the Mediterranean via the Dardanelles and Bosporus to the over-land "Silk Roads" to and from Central Asia, from where connecting routes extended overland to India and China). The choice between the two primarily sea route corridors mostly fell to the Persian Gulf route. It was both topographically and climatically preferred to the Red Sea route. Moreover, the Persian Gulf corridor had connecting routes overland to Central Asia, which came to serve as a central node in the transfer of surplus among the major zones of the world system. These three nexus corridors represented not only mere routes of trade. Repeatedly, they were integrated zones of economic and political development and recurrently the locus of attempts to build imperial systems. As the world system expanded and deepened, attempts were made by certain powers to place either two or all three corridors under a single imperial structure. Thus, such a power would control the key logistical interlinkages which have been central to the world system. For instance, the Assyrian empire attempted to control both the Syrian - Mesopotamian corridor and the Nile - Red Sea corridor, but succeeded only briefly and sporadically. The Persian empire likewise controlled both these corridors for a time, and it also had partial control over the Aegean - Black Sea - Central Asian corridor. Thus the Persian empire is the first historical instance of a "three corridor hegemony." Alexander the Great's grand strategic design for a world empire or "world system hegemony" included plans to control all three corridors, plus the Indus complexes and the west Mediterranean basin. His successors split the Macedonian conquests almost precisely into realms parallel to the three corridors. They allowed the Indus to fall out of Seleucid influence to the Mauryan empire and the west Mediterranean basin to control by Carthage and Rome. During the Hellenistic period, the recurrent rivalries between the Ptolomaic and Seleucid dynasties are indicative of continued struggles between the corridors for privileged position in the world system's accumulation processes. Even the Roman imperium did not entirely unify the three corridors however, since Mesopotamia was denied to Rome first by the Parthians, and later by the Sassanian Persians. They used their control of this area to extract considerable profit from the trade between Rome, India, and China. Of course, each of these three main corridors had competing/complimentary alternative variants and feeder routes of its own. For instance, there were several silk roads between East and West and different feeder routes in East and Central Asia and to/from South Asia. There were also routes connecting Northern and Western Europe through the Baltic Sea via the Dnieper, Don, Volga, and other Ukrainian and Russian routes. There were routes connecting the Adriatic to continental Europe, and the east Mediterranean to the west Mediterranean. Similarly, topological and other factors also favored some locations and routes as magnets of attraction and logistic nexuses in and around Asia. They deserve much more attention than they have received in world history. As the Asio-Afro-European nexus expanded and deepened, the number and role of these routes and choke points increased. At the same time, their relative importance changed vis a vis each other as a result of world system development. Locations such as the Straits of Malacca and of Ceylon had significant logistical roles for very long periods of world system development. The three overland and sea route corridors and their extensions were the most important nexuses between Europe and Asia for two millennia before the shift to transoceanic routes in the fifteenth and sixteenth centuries. This historic shift from the centrality of the three corridors to that of transoceanic logistical interlinkages was probably the single most important logistical shift in world history and world system development. However, rather than creating it a la Wallerstein (l974), the shift occurred within the already existing world system. III. INFRASTRUCTURAL INVESTMENT, TECHNOLOGY AND ECOLOGY 1. Infrastructural Investment and Accumulation Accumulation implies infrastructural investment and technological development. Infrastructural investment takes many forms in many sectors, such as agriculture, transportation, communications, the military, industrial and manufacturing infrastructure, and bureaucratic administration. There is investment even in ideological (symbolic) infrastructure, both of the cult of the state and of religion. In the state form of accumulation, the state seeks to create social wealth in order to extract it. By laying the basis for increases in production and facilitating accumulation, the state increases its own access to surplus and therefore its potential capabilities vis a vis rival states. This in turn helps it to protect "what we've got" and to get more. In the private form, the propertied elites likewise create wealth in order to extract it and invest in infrastructure to facilitate production and thereby accumulation. The ultimate rationale of such investment would in all cases be to preserve, enhance, and expand the basis of accumulation itself. The development of infrastructure and the technology it embodies feed back into the generation of surplus and accumulation. This growth of surplus in turn feeds back into further growth and development of infrastructure and technology in cumulative fashion. The pattern is spiral, whereby the world system itself grows and becomes more firmly "established" via infrastructural investment and accumulation. 2. Technological Innovation Technological progress in techniques of production, organization and trade, both military and civilian, has long played an important, and often neglected, role in the history of the world system and in the changing relations among its parts. Technological advance and advantage has been crucial throughout history in armaments, shipping and other transportation as well as in construction, agriculture, metalworking and other manufacturing methods and facilities. Progress, leads, and lags in all of these have had significant contributory if not causative effects on (and also some derivative effects from) the regional and other relations of inequality within the world system. Some examples were examined by William McNeill (1982) in The Pursuit of Power. Infrastructural investment is linked to technological change and to organizational innovation. Technological change in archaic and ancient periods, and even in medieval periods, was mostly slower than in modern industrial times. However, the essence of patterned relationships between technological innovation, infrastructural investment cycles, and the cycles of accumulation and hegemony (discussed below) probably have existed throughout history. When and what were the most significant technological innovations in world system history? Which innovations brought about restructuring of accumulation and of hegemony in the world system? Which altered the logistical interlinkages? The diffusion of technology across the world system is another major area for systematic and systemic analysis. In the general period of the contemporaneous Roman/Byzantine, Par- thian/Persian Sassanian, Indian Mauryan/Gupta and Chinese Han empires, cumulative infrastructural investments integrated each of these empires into a single world system. This high level of systemic integration was achieved via the well-developed logistic nexuses and the simultaneity of imperial expansion. At the end of that period, the entire world system experienced a general crisis. Hinterland peoples from Inner and Central Asia invaded Rome, Persia, India and China. They caused (or followed?) a decline in infrastructural investment and (temporary) serious disruption of the world system's logistical interlinkages compared to the previous era. How is infrastructural investment linked to productivity and increases in productivity to the processes of accumulation in the world system? Technological innovation and technological change has been pervasive in world system development. Gordon Childe (1942) pioneered a materialist analysis of the effects of technology on the ancient economy. Logistic capabilities, for instance those of maritime trade, depend on technological capability. So does the dynamic of military rivalry. Indeed, the expansion of the world system depended from the outset on technological capabilities. Invasions from the "barbarian" perimeter to the civilized centers depended upon the technological and military superiorities of the barbarians. Such invasions did not cease until "civilized" technological developments made the attainment of military superiority by the barbarians virtually impossible. By asserting a new military-technological superiority, the Russian and Manchu empires finally put an end to the strategic threat of Inner Asia in the seventeenth and eighteenth centuries AD. The industrial revolution gave European powers the military capability to destroy or subordinate contemporary empires in the world system such as the Mughal in India, the Qing in China, and the Ottoman in the three corridors region. 3. Ecology Technology has always been intimately associated with the ecological interface of the world system and its natural resource base. For instance, the technologies of farming created a secular trend to place more and more area under agricultural production, thus to increase the sources of agricultural surplus. Particular technological innovations have dramatically affected the ecological interface, particularly those of industrialized production. Since the introduction of these technologies, the trend has been their extension across more and more of the world system, often with devastating ecological consequences. There have been instances when environmental conditions brought about major changes in world system development. For instance, the salination of soils and silting up of irrigation works affected the relative economic strength of certain zones. For example, already before and even more after the sacking of Baghdad by the Mongols in 1258, Mesopotamia experienced relative decline. This was partly due to such environmental factors, and partly to shifts in logistical interlinkages in the world system. Certain areas have been extremely difficult to incorporate into the world system for primarily ecological and/or topographical reasons. These difficulties (still) characterize, for instance, the Tibetan plateau, the Amazonian basin, the Great Northern Arctic of Canada and the Soviet Union, and Antarctica. The social ecology of the peoples of Inner Asia, which Owen Lattimore (1940) contrasted to that of sedentary agricultural peoples, was a major factor in the world system's development for most of world history. The present ecological crises of industrial civilization remind us that ultimately ecology and the natural environment set limits on the expansion of the world system and on sustaining production and accumulation. If there have been any ecological cycles, rhythms, or trends, we should investigate what they are and how they have affected world system development. IV. SURPLUS TRANSFER AND ACCUMULATION RELATIONS 1. Surplus Transfer and Interpenetrating Accumulation The capture by elite A here (with or without its redistribution here) of part of the economic surplus extracted by elite B there means that there is "interpenetrating accumulation" between A and B. This transfer or exchange of surplus connects not only the two elites, but also their "societies'" economic, social, political, and ideological organization. That is, the transfer, exchange or "sharing" of surplus connects the elite A here not only to the elite B there. Surplus transfer also links the "societies'" respective processes of surplus management, their structures of exploitation and oppression by class and gender, and their institutions of the state and the economy. Thus, the transfer or exchange of surplus is not a socially "neutral" relationship, but rather a profoundly systemic one. Through sharing sources of surplus, the elite A here and the classes it exploits are systemically interlinked to the "mode of production," and even more important, to the mode of accumulation in B there. By extension, if part of the surplus of elite B here is also traded, whether through equal or more usually unequal exchange, for part of the surplus accumulated by elite C there, then not only B and C but also A and C are systemically linked through the intermediary B. Then A, B and C are systemically connected in the same over-arching system of accumulation. This means that surplus extraction and accumulation are "shared" or "interpenetrating" across otherwise discrete political boundaries. Thus, their elites participate in each others' system of exploitation vis a vis the producing classes. This participation may be through economic exchange relations via the market or through political relations (e.g., tribute), or through combinations of both. All of these relations characterize the millenarian relationship, for instance, between the peoples of China and Inner Asia. This inter- penetrating accumulation thus creates a causal interdependence between structures of accumulation and between political entities. Therefore the structure of each component entity of the world system is saliently affected by this interpenetration. Thus, empirical evidence of such interpenetrating accumulation through the transfer or exchange of surplus is the minimum indicator of a systemic relationship. Concomitantly, we should seek evidence that this interlinkage causes at least some element of economic and/or political restructuring in the respective zones. For instance, historical evidence of a fiscal crisis in one state or a zone of the world system (e.g., in third century Rome) as a consequence of an exchange of surplus with another zone would be a clear indicator of a relationship at a high level of systemic integration. Evidence of change in the mode of accumulation and the system of exploitation in one zone as a function of the transfer of surplus to another zone would also constitute evidence of systemic relations. Evidence of political alliances and/or conflict related to participation in a system of transfer of surplus would also be considered evidence of a systemic relation- ship. According to these criteria, if different "societies," empires, and civilizations, as well as other "peoples," regularly exchanged surplus, then they also participated in the same world system. That is "society" A here could and would not be the same as it was in the absence of its contact with B there, and vice versa. Trade in high value luxury items, not to mention precious metals in particular, may, contra Wallerstein (1974, 1989), be even more important than lower value staple trade in defining systemic relations. This is because the high value "luxury" trade is essentially an inter-elite exchange. These commodities, besides serving elite consumption or accumulation, are typically also stores of value. They embody aspects of social relations of production, which reproduce the division of labor, the class structure, and the mode of accumulation. Precious metals are only the most obvious example, but many "luxury" commodities have played a similar role, as is admirably argued by Jane Schneider in chapter 2 above. Thus, trade in both high value "luxury" items and staple commodities are indicators of interpenetrating accumulation. 2. Center-Periphery-Hinterland (CPH) Center-periphery-hinterland (CPH) complexes and hierarchies among different peoples, regions and classes have always been an important part of world system structure. However, the occupancy of musical chair places within this structure has frequently changed and contributed to the dynamics of world system historical development. To what extent (and why?) have the world system and its parts been characterized by center-periphery and other structural inequalities? Wallerstein (1974 and other works) and Frank (l978 a,b, 1981) among others, have posed questions and offered answers about the center-periphery structure of the world system since 1500. Ekholm and Friedman (l982), Chase-Dunn and Hall (Chapter 1) and others are trying to apply similar analyses to world systems before 1500. The "necessity" of a division between center and periphery and the "function" of semiperipheries in between are increasingly familiar, not the least thanks to the widespread critiques of these ideas. Chase-Dunn and Hall (Chapter 1) survey the propositions and debates. Wilkinson (Chapter 4) examines center-periphery structures all over the world for 5,000 years. Rowlands, Larsen, and Kristiansen (1987) analyze center and periphery in the ancient world. Indeed, now this entire book is dedicated to examining precapitalist center-periphery relations. We argue, however, that these relations also characterize this same world system for several millennia back. Chase Dunn and Hall (Chapter 1) and Wilkinson (Chapter 4) have already made the argument that center-periphery hierarchies characterize systemic development much further back in world historical development than 1500 AD. In fact, center-periphery relations characterize development since the origins of the state and systems of states. However, we agree with Thomas Hall (l986 and chapter 7 below) that we need a more comprehensive "center-periphery-hinterland" (CPH) concept than most other scholars have used. Hall (l986) refers to "contact peripheries." This hinterland is not directly penetrated by the extracting classes of the center, but nevertheless it has systemic links with the center-periphery zone and its processes of accumulation. Wallerstein's use of the term hinterland to mean external to the world system is insufficient because it neglects the structural and systemic significance of zones which are "outside" of, but nonetheless related to, the center-periphery complex. We, of course, wish to stress the contribution to accumulation among all participants, especially through the transfer of surplus, made by these hinterland-periphery-center "contacts." These CPH relationships have been insufficiently analyzed. The CPH complex does not refer to mere geographical position, nor only to unequal levels of development. CPH also refers to the relations among the classes, peoples and "societies" that constitute the mode of accumulation. The CPH complex is the basic social complex upon which hegemony, as discussed below, is constructed in a larger systemic context. More research is necessary on how "geographical" position in a hegemonic structure affects class position in the CPH complex. We could expect to find that the class structure of a hegemonic state may be significantly altered by the surplus that this state accumulates from its subordinates in the CPH complex. For example, the subsidy to the plebeian class of Rome may be taken as an example of such systemic effects. Conversely, we might expect a CPH complex to give rise to increased exploitation of producers in subordinate positions. The "hinterland" contains natural resources, including human labor, which are tapped by the center-periphery. However, what distinguishes the hinterland from the periphery is that the peoples of the hinterland are not fully, institutionally, subordinate to the center in terms of surplus extraction. That is, they retain some degree of social autonomy. If a hinterland people come under political means of extraction by the center, then the process of "peripheralization" begins. Nevertheless, despite a degree of social autonomy from the center, the hinterland is in systemic relations with the center. The frequency of center-hinterland conflict is one indicator of such systemic relations. The hinterland may also have functional roles in logistical interlinkage. In this sense, the hinterland may facilitate the transfer of surplus between zones of the world system. These roles of hinterlands merit as much theoretical attention in determining positional shifts and systems change as those of semiperipheries. The center (or core) - periphery - hinterland concept is not intended to replace, but to extend, Wallerstein's (1974 and elsewhere, Arrighi and Drangel 1986) core - semiperiphery - periphery formulation. However, the semiperiphery has always been a weak and confusing link in the argument. The hinterland "extension" may confuse it still further and may counsel reformulation of the whole complex. For instance at a recent conference (with Wallerstein, Arrighi and Frank among others), Samir Amin suggested that the semiperiphery has functionally become the real periphery, because it is exploited by the center; while the "periphery" has been marginalized out of the system, because it no longer has anything (or anybody) for the center to exploit for its own accumulation. As argued above however, historically the hinterland has also contributed to core accumulation in the CPH complex. Thus, CPH complexes are integral to the structure of the world system in all periods. They must be studied, not only comparatively, but also in their combination and interaction in the world system. It is important to examine how center - periphery zones expanded into the hinterland in order to understand the way in which accumulation processes were involved. The rationales of expansion and assimilation in the hinterland appear to be related to the "profitability" of such expansion, in terms of tapping new sources of surplus. They also help resolve internal contradictions in the center-periphery complex brought about as a result of exploitation and demographic pressure. Class conflict in the center-periphery complex is affected by the expansion of accumulation into the hinterland. Demographic trends are an important factor; the hinterland provides new resources to sustain the growing population of the center-periphery zone. The physical geographical limits of hinterland peripheralization by the center seem to be set by both logistical capabilities and by a cost-benefit calculus. Areas are occupied primarily if they can be made to pay for the cost of their own occupation or are deemed to be strategically necessary to protect another profitable area. Conversely, such areas are again abandoned if, or when, their occupation proves to be too costly. Fortification at such systemic boundaries has a dual function of keeping the barbarians out and keeping the producers in. That is, such fortification impedes military disruption of the zone of extraction and also impedes the escape of dependent-subordinate producers into the "free" zone. 3. "Barbarian" Nomad - Sedentary "Civilization" Relations It is important to examine how systemic links between center and hinterland are formed. How does the hinterland interact over time with the center-periphery complex and thereby affect changes in the structure of that complex itself, and vice versa? A particularly important aspect of this question is the nature of the historical relations between the so-called tribal "barbarians" and the so-called "civilized" "societies." How are the barbarians "assimilated" into civilization and yet also transform civilization? Throughout most of world history, this barbarian-civilization relationship has been crucial to the territorial expansion of the state, imperialism, and "civilization." The work of Arnold Toynbee (1973), Thomas Hall (1986, 1989), Eric Wolf (1982), William McNeill (1964) and Owen Lattimore (1940, 1962) illuminate many aspects of how these center-periphery-hinterland hierarchies are created, deepened, and systemically transformed. Toynbee's "system implosion" is of particular interest. Robert Gilpin (1981) follows Toynbee to show how an older center is eventually encircled and engulfed by new states on the periphery, which implode into the center. Thus, a "center-shift" takes place by way of an implosion from the former periphery to the center of the system. For instance, this occurred with the creation of the Qin empire at the end of the Warring States period in China. It also happened with the creation of the Macedonian empire at the end of the classical period in Greece. In even earlier examples of such hinterland impact, the "tribal" Guti, the Amorites, the Kassites, and the Akkadians were intimately involved in the political cycles of archaic Mesopotamia. Each of these peoples made a transition from hinterland roles to that of ruling class in the center. Moreover, these invasions of the center by the hinterland took place for systemic reasons, not just gratuitously. Eberhard (1977) and Gernet (l985) analyze how Inner Asian nomads repeatedly invaded China to appropriate its productive structure and economic surplus. Frederick Teggart's (1939) study of correlations of historical events in Rome and China analyzes the systemic causal connections across the whole Asio-Afro-European economic nexus, which caused hinterland-center conflict in one zone to affect relations in another zone. The sequencing of conflicts follows a logic that corresponds to both logistical elements in the nexus, struggles over shares of accumulation, and social tensions due to the expansionary pressure of the center-periphery complex into the hinterland. V. POLITICAL ECONOMIC MODES OF ACCUMULATION 1. Modes of Accumulation If we are to study any "modes" at all, we might better study the modes of accumulation, instead of the "mode of production." In the world system, production is the means to an end. That end is consumption and accumula- tion. It may be useful to study the differences, the mutual relations, combinations or the "articulations" of "public" (state) and "private" and "redistributive" and "market" modes of accumulation. It is doubtful that any of these modes, or other modes, have ever existed alone in any pure form anywhere. However, we should study not only how modes of accumulation differ and combine with each other "locally," but also how they interconnect with each other throughout the world system as a whole. Thus, world system history should both differentiate and combine modes of accumulation: horizontally through space as well as vertically through time. The "articulation" of modes is a way of analyzing how the mode(s) of accumulation in one zone of the world system is(are) affected by systemic links with other zones' mode(s) of accumulation. Can the overall world system be characterized by a single mode of accumulation? If not, why not? Shifting the focus of analysis from production to accumulation need not abandon analysis of the class structure. In fact, a focus on the relations of accumulation should sharpen the analysis of class relations. Geoffrey de Ste Croix (1981) argues that the key to every social formation is how the "propertied classes" extract the surplus from the working classes and ensure themselves a leisured existence. He defines a mode of production based on the means by which the propertied classes obtain most of their surplus. This approach is an alternative to trying to determine what form of relations of production characterize the entire social formation. That is, he focuses on the dominant mode of accumulation. Ste Croix delineates several means of extracting surplus: wages, coerced labor (in many variants), rent, and through the state (via taxes, corvee labor, and through "imperialism"). Interestingly, Ste Croix explains the fall of the late Roman empire as due primarily to gross over-extraction of surplus, over-concentration of wealth in the hands of the upper classes, and the over-expansion of the bureaucratic and military apparatus (1981 pp 502-503). The latter is similar to Paul Kennedy's (1987) argument about military-economic overextension in The Rise and Fall of the Great Powers. This analysis implies a link between cycles of accumulation and cycles of hegemony, to which we will return below. Equal, or perhaps even greater, analytical emphasis is necessary on horizontal inter-elite conflicts over apportioning "shares" of the available social surplus. This struggle has its focus in the ultimate political determination of the mode of accumulation. To say that the elites of different zones of the world system share in each others' system of exploitation and surplus extraction through interpenetrating accumulation, is not to deny possible differences between these zones in terms of the mode of accumulation. The exchange or transfer of social surplus both affects and is affected by class structure. However, interpenetrating accumulation affects both the producing strata and the extracting-accumulating strata, though in different ways. 2. Transitions in Modes of Accumulation Perhaps the single greatest weakness in historical materialism to date has been the failure to theorize transitions between modes in a world systemic context. Traditional Marxist interpretations of world historical development relied heavily on a schema of transitions between modes of production in a predetermined unilinear progression. This overly simplistic framework of analysis has long since been abandoned and revised by most historical materialists. We propose instead to study transitions between modes of accumulation. However, they did not occur merely within each "separate" zone of the world system. Rather they were the key determinants of transition in both the "parts" and especially the whole of the world system. Therefore, the research task is not to search solely or even primarily for indigenously generated determinants of transition between modes, but rather to analyze the overall interactions of each zone of the world system with the dynamic of the entire world system. This is true of both the economic and the political aspects of modes of accumulation. It would also be a mistake to attempt too strict an analytical separation between "agrarian" and "industrial" modes of accumulation in the world system. Even in very archaic phases of the world system, the economic nexus included non-agricultural sources of production and accumulation. The role of industry and commerce before the onset of "industrialization" in the modern world system require much more study than they have received. The associated social and political relations of accumulation have changed very significantly across world historical time, but not in any predetermined or unilinear progression of modes of accumulation. The precise nature and timing of such transitions is still an open empirical question. 3. Public/Private Accumulation In principle, there are four possible permutations of private and public accumulation:  1. Dominant Private Accumulation (the state "facilitates" private accumula tion).  2. Dominant State Accumulation (private accumulation "facilitates" state accumulation).  3. All Private Accumulation.  4. All State Accumulation. Type 1, dominant private accumulation, may correspond to mercantile states and to modern democratic states. Type 2, dominant state accumulation, may characterize a number of bureaucratic states and empires as well as certain modern authoritarian regimes. Type 4, all state accumulation, might be characterized by states such as ancient Sparta, the Inca empire, and some modern (state) "socialist" states. Type 3, all private accumulation, raises the theoretical question of whether private accumulation is in fact possible at all without the state, or at least without the presence of the state somewhere in the overall economic nexus. There may be niches in the world system's economic nexus where all private accumulation may occur, but it has been difficult to identify instances of this. State accumulation is typically characterized by a much larger scale and much greater potential capabilities to extract surplus than any sole private accumulator is capable of organizing. That is why "imperialism" is such an attractive means of accumulation. State accumulation centralizes accumulation more than private accumulation. For this reason, these two modes of accumulation and their respective elites are locked into a perpetual conflict over apportioning the shares of the surplus. Both private accumulating classes and the state elite, as a "state-class," struggle to form a coalition of class fractions. Such a "hegemonic bloc" of class fractions allows them to cooperate to utilize the political apparatus to establish the dominant mode of accumulation. The oscillation between predominance by the private accumulators and the state class in a social formation is a key dimension of the cycles of accumulation, discussed below. 4. Economy/Polity Contradictions There is a contradiction between a relatively unbounded economic nexus and a relatively bounded political organization of this economic nexus in world system development. The total economy of the major states and centers of the world system is not under their sole political control. This tension is universally recognized today as affecting the structure of modern capital accumulation. However, this phenomenon is not new. This economy-polity contradiction is characteristic not only of the so-called contemporary age of "interdependence," but has in fact always been a factor in world system development. Even though since its origin the world system has developed logistical interlinkages that create a single overarching economic system, the political organization of the world system has not developed a parallel unity. Why is that? For the modern world system, Wallerstein (1974 and other works) argues that the capitalist mode of production structurally inhibits the creation of a single "world-empire." That is, in this view the resolution of the economy/polity contradiction in the modern world system by a single overarching political entity is inhibited by its capitalist mode of production. However, it appears that even in other modes of accumulation, it has not been possible to create a single political structure for the entire world system. Attempts to do so have been failures. The Mongol attempt in the 13th century perhaps came closest to success. The question of why the world system has never successfully been converted into one political entity should be seriously posed. The answer may be structural, or simply a matter of logistical and organizational limitations. Whatever the answer to this question about politics in the world system, it need not deny and may even strengthen the thesis of its essential economic unity. VI. HEGEMONY AND SUPER-HEGEMONY 1. Hegemony Hegemony is a hierarchical structure of the accumulation of surplus among political entities, and their constituent classes, mediated by force. A hierarchy of centers of accumulation and polities is established that apportions a privileged share of surplus, and the political economic power to this end, to the hegemonic center/state and its ruling/propertied classes. Such a hegemonic structure thus consists schematically of a hierarchy of CPH complexes in which the primary hegemonic center of accumulation and political power subordinates secondary centers and their respective zones of production and accumulation. The rise and decline of hegemonic powers and cycles of hegemony and war are lately receiving increasing attention, e.g., by Modelski (l987), Thompson (1989), Wallerstein (1974, 1988), Wight (l978), Goldstein (l988) and others, and even best seller status (Kennedy 1987). Most of these studies confine themselves to the world system since 1500. However, (we argue that) the world system began earlier and was previously centered outside Europe. Therefore, the same, and even more questions, about hegemonic rise, decline, cycles, and shifts apply - and even more interestingly - to the larger and older world system, prior to Europe's rise to super-hegemonial economic and political power within it. Where and when were there hegemonic centers in the world system before 1500, and in what sense or how did they exercise their hegemony? David Wilkinson (1989) has made a systematic study of world states and hegemonies that could serve as the starting point for an answer. The following are some other important questions. As one hegemonic center declined, was it replaced by another and which and why? Were there periods with various hegemonic centers? Did they "coexist" side by side, or with how much systemic interconnection? In that case, did they complement each other, or did they compete with each other, economically, militarily, or otherwise until one (new?) center achieved hegemony over the others? Rather than continuing to look merely comparatively at contemporary hegemonic structures in different zones of the world system or to investigate the dynamic of each region separately, we must look at systemic links among all the constituent political organizations of the world system. Of course, these especially include contemporaneous hegemonic structures. Hegemony takes a variety of historical forms. They vary from highly centralized integrated bureaucratic empires, to very loosely structured commercial or maritime hegemonies. In the latter, much of the surplus is captured not via direct political coercion, but via commodity exchange, albeit via unequal exchange. How and why do these various forms of hegemony occur at particular times and places? How do they reflect the interests of the actors which choose them and the prevailing conditions in the world system at the time? Given the absence in the historical record of any single "world system hegemony," we must look to the rise and decline of hegemonies in each of the major zones of the world system in order to construct an overall picture of the hegemonial cycles, rhythms and trends in the various regions and their possible relations. For instance, the oscillation between unitary hegemonies and multi-actor states systems has already been recognized as a key pattern of world historical development (Mann 1986, Wilkinson 1989). These oscillations and the succession of hegemonies in each part of the world system should not be analyzed only on a comparative basis, but from a world systemic perspective. Only in this way can the dynamics of the world system's economy/polity contradiction be more fully understood. All this suggests that the primary object and principal economic incentive of a bid for hegemony is to restructure the overarching system of accumulation in a way that privileges the hegemon for capital/surplus accumulation. Simply put, hegemony is a means to wealth, not merely to "power" or "order." That is, "power" in the world system is both economic and political at all times. In fact, economic power is political power, and vice versa. Turning Michael Mann (1986) on his head, the ends of power are above all control over accumulation processes and the determination of the dominant mode of accumulation. The processes of accumulation are more fundamental to world system history than Mann's forms of social power per se. The political and economic processes in the world system are so integral as to constitute a single process rather than two separate ones. Success in accumulation plays a critical role in success in a bid for hegemony. This is true not only of modern states, but even of archaic ones. For instance, the victory of the state of Qin in the Warring States period in Chinese history depended greatly on its innovations in tax structure, infrastructural investments, bureaucratic administration, and trade links to the world system. All of these gave the Qin very real advantages in accumulation and in military capabilities over its more traditional "feudal" rivals. 2. Cycles of Accumulation and Hegemony The perpetual "symbiotic conflict" between private accumulating classes and state accumulating classes is indicative of cycles of accumulation. The oscillation between unitary hegemonies and multi-actor states systems is indicative of cycles of hegemony in the world system. Cycles of accumulation and cycles of hegemony are probably causally interrelated. This causal inter- relationship appears to date from very early in world system history in various parts of the world system. These cycles and their interrelationship are the central phenomena of the world system's longest cumulative patterns. These cycles have partly been analyzed by Gills' (1989) analysis of synchronization, conjuncture, and center-shift in the cycles of East Asian history. Briefly, prior to the in- dustrialization of production, the phase of accumulation in which private accumulating classes become dominant seems to be closely associated with the decline of hegemonies and their political fragmentation. That is, decentralization of accumulation affects the decentralization of political organization. These processes may be called "entropic." Phases of accumulation in which the bureaucratic state elite is dominant seem to be associated with the consolidation of hegemonies. That is, the centralization of accumulation affects the centralization of political organization and vice versa. However, rising and declining hegemonies also call forth opposing (and also temporarily supporting) alliances to thwart existing and threatening hegemonial powers. Shifting alliances seem to promote some kind of "balance of power." All this may seem obvious, but the cyclical dynamic of hegemony (also through political conflict and shifting alliances) in relation to the process of accumulation has not previously been given the attention it deserves. Implosion from the hinterland upon the center appears to be most likely to occur in entropic phases of the system. The hinterland, and perhaps the periphery, take advantage of weakness or entropy in the center to restructure the structure of accumulation. This may occur by usurping political power at the center, or by "secession" from the center altogether. Too much attention has been given only to the political and strategic aspects of long cycles of war and leadership to the exclusion of the underlying dynamics of accumulation. General war, as Modelski (1987) argues, does indeed produce new sets of victors who go on to establish a new order. However, one should not merely examine the political and military aspects of these cycles. The new victors, without exception, also proceed to restructure the structure of world accumulation. This, and not mere political realignments or "order" alone, is the ultimate end of such general conflict. The intense military rivalry that precedes hegemony may stimulate production, but much of the economic benefit is consumed in the process of rivalry and war. Typically, a new hegemony is followed by a period of infrastructural investment and economic expansion, which is "the hegemonic prosperity phase" of accumulation. A unified hegemony usually reduces or even eliminates previous political obstructions to the greater integration of the economic nexus. This has a tremendous impact on the process of accumulation. We must contemplate the existence, and study the development of a wider world system farther back in world history to find answers to a host of questions about the dynamics of states systems and cycles of accumulation and hegemony. Particularly important are questions about the existence of world system wide accumulation processes and shifts in the centralization of accumulation from one zone of the world system to another. How do such shifts affect cycles of hegemony? What are the real patterns and "laws" of the world system's overall expansion, transformation, and decay? 3. Super-Hegemony The historical process of economic surplus management and capital accumulation is so interregional and inter-"societal" as to lead to the conclusion that it constituted a process of world accumulation in the world system over the millennia. A privileged position therein, in which one zone of the world system and its constituent ruling-propertied classes is able to accumulate surplus more effectively and concentrate accumulation at the expense of other zones, could be called "super-hegemony." Thus, super-hegemony is also a class position in the overarching world accumulation processes of the world system. Thus, while there may at one time be different hegemonic powers in the regional subsystems, only one of them would be "super-hegemonic" if and when it is "more equal than the others" some of whose accumulation it manages to channel to itself and to centralize in its own super-hegemonic "super-accumulation." A research agenda is to examine the causes of possible super-hegemony, positional shifts from one zone to another, and the degree to which super-hegemony is transformed into further economic and political power within the world system. While hegemony is built up of CPH complexes, super-hegemony occurs in the largest field possible, that of the entire world system and all of its constituent hegemonic structures. Thus, super-hegemony links all the constituent hegemonies into one overarching systemic whole. Of course, the degree of institutional integration among distinct hegemonies is not as great as the degree of integration within each hegemony. Nevertheless, contemporary and/or contiguous hegemonies are not autonomous if inter-penetrating accumulation exists. In the entire class structure of the world system, in whatever mode of accumulation, the super-hegemonial class position is the most privileged and the ultimate "center of centers" in the world accumulation process. To what extent did this overarching super-hegemony rest or operate on more than the mere outward exercise of political power and the radiation of cultural diffusion? In particular, to what extent and through what mechanisms did such overarching super-hegemony include centralized (super-hegemonial) capital accumulation? Was accumulation fed through the inward flow and absorption of economic surplus generated in and/or transferred through other (sub)-hegemonial centers? The answers to both questions are in general affirmative, and we can find ample confirmative historical evidence if we only look for it. For instance, William McNeill (in conversation with Frank) suggests that China itself accumulated capital by absorbing surplus and capital from the West in the several centuries before 1500 AD. Was China therefore super-hegemonial? Prior to China, India was possibly super-hegemonial in the world system. In the period of the eighth and ninth centuries AD, the Abbassid Caliphate, with its great metropole at Baghdad, may have been super-hegemonial. The development of European domination over the Mughal, Qing and Ottoman empires should, however, also be understood in terms of the conjuncture of European expansion and these regions' entropic phases of accumulation and hegemony. In the nineteenth century, Great Britain is a candidate for super-hegemonial status, followed by the United States in the mid-twentieth century, and possibly Japan in the very late twentieth and early twenty-first century. Thus, super-hegemony need not be limited only to the capitalist world economy, but may have existed at other times in the history of world system development. Super-hegemony is more flexible than empire, or imperialism. Super-hegemony operates not only through political and inter-state level(s) of diplomacy, alliance, and war, but also and maybe more importantly, through super-accumulation. If super-hegemony existed before recent times, how, when and why did the super-hegemonial center of the world system, the most favored locus of accumulation, shift around the world system? What effects did such shifts in super-hegemonial centers have upon and what "functional" role, if any, did they play in the world system's development? For instance, the super-hegemony of the Abbassids in the eighth century was reflected in their ability to defeat Tang China at Talas in 751, their treaty of alliance with the Tang in 798 AD, and their continued ability to control Central Asia. Perhaps the super-hegemony of Britain contributed to its ability to arbitrate the balance of power on the continent of Europe and to defeat bids to impose a unitary hegemony, such as that by Napoleon? The super-hegemony of the United States after 1945 allowed it to restructure the international order and greatly expand its economic and military influence in the world system. It remains to be seen whether or how Japan might translate super-hegemonial status in world accumulation processes into further political and economic power in the world system in the twenty-first century. 4. Cumulation of Accumulation How long, then, has there been an overarching and interpenetrating world system process of capital accumulation, which affected the structure of the structures of which it is composed? In other words, how long has there been a cumulative process of capital accumulation on a world system scale? The (occasional and temporary) existence of super-hegemony also implies super accumulation at those times, as noted above. Even in the absence of super-hegemony, however, the process of accumulation in one zone of the world system would not have been the same without the linkages to the process of accumulation in another zone or zones of the world system. Therefore, even competing hegemonies and linked structures and processes of accumulation could have contributed to the world system wide cumulation of accumulation. Indeed, such an overarching structure of accumulation and the resulting process of cumulation of accumulation implies that there may be a unitary "logic" of systemic development. The cumulation of accumulation in the world system thus implies not only a continuous, but also a cumulative, historical process of ecological, economic, technological, social, political, and cultural change. Cumulation of accumulation involves or requires no uniformity among these processes throughout the system or its parts, no unison among its parts, no unidirectionality of change in either the parts or the whole, and certainly no uniformity of speed of change. On the contrary, both the historical evidence and our analysis suggest unity through diversity (to use the phrase Mikhail Gorbachev used at the United Nations). The unity of the world system and its cumulative process of accumulation is based on the diversity of center-periphery-hinterland, mode of accumulation, and hegemonic differences we have emphasized. Of course they also rest on the variety of social, gender, racial, ethnic, cultural, religious, ideological and other differences, which characterize wo/mankind. Historical change in both the whole (system) and its parts takes place in many "progressive" and "retrogressive" directions, and not unidirectionally or even in unison between here and there. For this reason among others, historical change also takes place and even cumulates, not uniformly, but at changing rates, sometimes fast, sometimes slowly, sometimes (degenerating) in reverse. Indeed, as in physical transformations and in biological evolution, historical change suddenly accelerates and/or bifurcates at critical junctures. More than likely, contemporaries are rarely aware that they are living and acting in such "special" periods -- and many who think so at other times, are not. Hindsight seems to throw more light on history than foresight or even contemporary side-sight or introspection. Yet even historical hindsight has a long way to go, especially in grasping the dynamics and variability of historical change. We briefly return to these problems below under the title of "dynamics." VII. A HISTORICAL MATERIALIST POLITICAL ECONOMY AND RESEARCH AGENDA 1. Historical Materialist Political Economic Summary and Conclusions In this paper we made three key arguments. The first is that the world system pre-dates the development of modern capitalism, perhaps by several thousand years. The second is that accumulation processes are the most important and fundamental processes of the world system throughout its development. The third argument is that, though the mode of accumulation underwent many historical transformations, there has been a continuous and cumulative process of accumulation in the world system. Therefore, we argue that a new research agenda is needed to focus more analysis on these cumulative processes of accumulation over the entire historical development of the world system - of some five thousand years at least. The secular trends, cycles, and rhythms of the modern capitalist world system thus become more contextually understandable within the much longer cycles, trends, and rhythms of the historical world system, and particularly of its process and cycles of accumulation. We based our argument upon a new set of criteria for defining what constitutes a "systemic" interaction. The transfer or exchange of economic surplus is the fundamental criterion of a world systemic relationship. Diplomacy, alliances and conflict are additional, and perhaps derivative, criteria of systemic interaction. Thus, we introduced the criterion of "interpenetrating accumulation" into the definition of the world system. By applying these criteria we saw the origins of the world system recede by several millennia. The world system had its ultimate origins in the development of an archaic Asio-Afro-European economic and political nexus, which first developed in the area now known as West Asia, the Middle East and the Eastern Mediterranean about 2500 BC. Once in existence, this world system continued to develop, expand, and deepen. It eventually either assimilated and/or merged with all other center-periphery- hinterland zones to form our modern world system. Its relatively unbounded economic nexus is perpetually in contradiction with a more bounded political organization of the economic nexus. Cycles of accumulation and cycles of hegemony, like center-periphery- hinterland relations, have characterized the world system and its subsystems from its inception. World system history forms a genuine continuum within which cycles of accumulation and cycles of hegemony are the two most fundamental phenomena. These two cyclical phenomena are intercausally systemically interrelated to one another. They are the basis of our assertion that there are cumulative accumulation processes in the world system over such an extended time frame. Significant aspects of our argument were anticipated - alas, without our taking due note thereof - by Kajsa Ekholm and Jonathan Friedman (E & F) under the title "'Capital Imperialism and Exploitation in Ancient World Systems" a decade ago (1982, original 1979). It may be useful briefly to review some major points of agreement and disagreement with them. 1. Emergence and development of the World system. E & F argue that Our point of departure is that the forerunner of the present kind of world system first emerged in the period following 3000 B.C. in Southern Mesopotamia. Here we can describe the first example of the rise of a center of accumulation within a larger economic system and the development of an imperialist structure....the expansion of the E.D. [Early Dynastic] system eventually incorporates the entire region from the Indus to the Mediterranean in a regular trade network....(89, 97). Our argument is that the general properties of imperialist-mercantilist expansion are common to ancient and modern worlds irrespective of specific local forms of accumulation (92). We agree that the world system began long before "the modern world system," and we also see its emergence in Mesopotamia. However, in our view the formation of the world system was more the result of interregional relations between Mesopotamia and other regions in the "Middle East" and the Indus Valley. We also agree that the world system then expanded and took on certain "general properties," which still define it today (see below). 2. Capital Accumulation. E & F and we agree on the centrality of capital accumulation in this long historical process and system(s) and that "capital" exists not only under "capitalism." The accumulation of capital as a form of abstract wealth is a truly ancient phenomenon.... "Capital" is not tied to a specific form of exploitation. It is, rather, the forerunner, or perhaps identical to, merchant capital in its functioning....(pp. 88, 100). However, E & F define capital as: ...the form of abstract wealth represented in the concrete form of metal or even money that can be accumulated in itself and converted into other forms of wealth, land, labor, and products (p. 100). Our concepts of capital and its accumulation are broader than theirs. We stress the existence and combination of both state and private capital, and we include non- monetary forms of the production, extraction, transfer, and accumulation of surplus. We also pay more attention than they do to the interregional dimensions of accumulation and supra regional super accumulation. Moreover, we stress the cumulative, albeit cyclical, process of capital accumulation -- which also contributes to continuity in the world system. 3. Center-periphery Structure(s). E & F, like we, argue that The system to which we refer is characterized, not only by an accumulation of capital, but by the emergence of an imperialist pattern: center/periphery structures are unstable over time; centers expand, contract, and collapse as regular manifestations of the shift of points of accumulation. These phenomena are, we think, more general than modern capitalism....(88). We agree, but our CPH complex extends this center-periphery structure to include the hinterland, when it also contributes to accumulation in the center and to transformation in the system as a whole. Moreover again, we stress the systemic relations among various CPH complexes, which make up the world system as a whole. 4. Economy/Polity Contradictions, Hegemony and System Transformation. E & F and we agree that systemic economic relations tend to be more extensive than political ones. The existence of a production/resource area wider than that of a political unit which must be maintained is the fundamental weakness of such systems (93). This contradiction gives rise to instability in and transformation of the system: Center/periphery structures are drastically unstable because of the vulnerability of the centers in the external (supply/market) realm which is so difficult to control....Evolution is, as a result, a necessarily discontinuous process in space. Centers collapse and are replaced by other areas of high civilization. The development of total systems is not equivalent to the development of individual societies. On the contrary, the evolution tends to imply the shift of centers of accumulation over time....(93). Again, we agree; but we discuss these relations and transformations as cycles of hegemony. We also relate hegemony to the center-periphery complex and to accumulation within it. However, we also urge the study of possible overarching system-wide super- accumulation and super-hegemony. 5. World systems or World system? E & F seem to be unsure about which it is. Elsewhere, they definitely say systems, (eg Ekholm 1980). Here E & F say: Our point has been to stress the fundamental continuity between ancient and modern world- systems.... We are, perhaps talking about the same world system. The forms of accumulation have not changed so significantly. The forms of exploitation and oppression have all been around from the earliest civilization although, of course, they have existed in different proportions and varying combinations....There are, to be sure, a great many differences, but the similarities are, perhaps, a more serious and practical problem (105, 106). That is our point as well. However, we now wish to stress the fundamental similarity and continuity not so much between ancient and modern world systems. We are definitely talking about common characteristics and continuity within the same world system. Therefore, there is good reason, justification, and merit to do an historical materialist political economy of world system history. Almost all historical and (other) social scientific analysis of the world and its parts before 1500 AD (and most of them for the time since then also) have neglected these systemic aspects of world historical political economic processes and relations. Some scholars (e.g., Tilly 1984) have considered doing such a world system history and have rejected the task as inadvisable or impossible. Others, like Farmer (1977, 1985), Chase-Dunn (1986), Ekholm (1980), and Ekholm and Friedman (1982) have started down this road, but have apparently taken fright and stopped or even turned back. A few scholars, especially Childe (1942), McNeill (1964, 1990), Stavarianos (1970), and most recently Wilkinson (1987, 1989) have made pioneering advances toward writing a world system history. Frank (1990) examines their and many other theoretical and historical considerations and rejects their reservations as unfounded. He then proposes why and how these and other pioneering works should be extended and combined to do a history of the world and its world systemic historical materialist political economy along the present lines. 2. Political, Economic and Cultural Three Legged Stools A historical materialist political economy of cumulation of accumulation in world system history does not exclude or even downgrade social, political, cultural, ideological, and other factors. On the contrary, it relates and integrates them with each other. Nor need such a study be "economic determinist." On the contrary, this study would recognize the interaction and support of at least three legs of the social stool, without which it could not stand, let alone develop. These three legs are: the organization of political power; the identity and legitimation through culture and ideology; and the management of economic surplus and capital accumulation through a complex division of labor. Each of these is related to the other and all of them to the system as a whole and its transformation. A historical materialist political economic analysis of the historical development of this world system should incorporate ecological, biological, cultural, ideological, and of course political factors and relations. Thus, there is justification and merit in also seeking to explain many political institutions and events and their ideological manifestations through the ecological and economic incentives and limitations that accompany if not determine them. In particular, we should pay much more attention to how the generation and capture of economic surplus helps shape social and political institutions, military campaigns, and ideological legitimation. Economic institutions, such as Polanyi's (1957) famous reciprocity, redistribution and market, appear mixed up with each other and always with some political organization. Many political institutions and processes also have economic aspects or "functions." The three component aspects, the three legs of the stool, are embedded in the mode of accumulation. No mode of accumulation can function without a concomitant ideology of accumulation; an economic nexus founded on a complex division of labor in which class relations facilitate extraction of surplus; and finally a political apparatus, which enforces the rules and relations of accumulation through the ultimate sanction of "legitimate" coercion. The ideology and political apparatus are integral aspects of the mode of accumulation. They are not super - structurally "autonomous" from each other or from the characteristics of the economic nexus. However, ideology and political competition and emulation sometimes appear to take on at least a semi-autonomous character. Even if we grant this, it does not invalidate the alternative assertion that overall they are not autonomous from the economic nexus. We reject any vulgar unidirectional schema of causality whereby the economic nexus must necessarily determine the ideology and political apparatus of a mode of accumulation because they are not in fact separate. We suggest an alternative concept of the mutual inter-causality among the three aspects of a mode of accumulation which is historically specific to each case. Indeed, particularly in periods of transition between one mode of accumulation and another, ideological and political forces can play an extremely significant role in determining the structure of the economic nexus that emerges from the transition. It is in these periods especially that broad based social movements intercede in world (and local) history. These social movements are often neglected altogether, or they are considered but not sufficiently analyzed in their structural and temporal world systemic context. We can well depart from vulgar economism, but not necessarily from a form of "economic" determinism, if by economic we mean giving the political economic processes of accumulation their due. 3. Analytic and Research Agendas on the Structure and Dynamics of World system history. Most important perhaps are the dynamics of the world system, that is how the world system itself operates, behaves/functions, and transforms (itself?). Are there trends, cycles, internal mechanisms of transformation in the pre-(and post-) 1500 world system? When and why does historical change accelerate and decelerate? What are the historical junctures at which quantitative turns into qualitative change? What are the bifurcations at which historical change takes one direction rather than another. And why? Perhaps general systems theory offers some answers or at least better questions also for this (world) system. For instance, Prigogine and Sanglier(1988) analyze how order is formed out of chaos, and how at critical times and places small changes can spark large alterations and transformations in physical, biological, ecological and social systems. Recent studies by, for instance, Ekholm and Friedman (1982), Chase-Dunn (1986), and others are looking into both structural and dynamic properties of partial "world" systems before 1500. However, it may be possible to trace long (and within them shorter) cycles of accumulation, infrastructural investment, technological change, and hegemony much farther back in world system history. Not only may they have existed, but they may often have had considerable relative independent autonomy from policy and politics per se. Indeed as in more recent times also, much of this policy was, and is, instead more the effect of and response to largely uncontrolled cyclical changes. Moreover, policy tends to reinforce more than to counteract these cycles and trends. This cyclical process and policy response may be seen in the decline of various empires, including the present American one. In particular, to what extent has the process of capital accumulation and associated other developments been cyclical? That is, were there identifiable subsystemic and system-wide acceleration/deceleration, up/down, swings in structure and process? And were any such swings cyclical, that is endogenous to the system, in the sense that up generated down and down occasioned up again? This kind of question has been posed, and some answers have been offered for the world system (or its different economic and political interpretations) since 1500. For instance, Wallerstein (l974) and Frank (l978) find long cycles in economic growth and technology. Modelski (l987) and Goldstein (l988) find long cycles in political hegemony and war. Wallerstein also posits a life cycle of expansion and foreseen decay of the system. Toynbee (l973), Quigley (l961), Eisenstadt (1963), and others have made comparative studies of the life cycles of individual civilizations before 1500. So have archaeologists like Robert M. Adams (1966). But to what extent were there also world system wide fluctuations and cycles, and what role have they played in the transformation and development of the world system? Infrastructural investment apparently occurs in cyclical or phased patterns, and in direct correspondence with the cycle/phase of accumulation and of hegemony. Newly formed hegemonic orders are usually associated with a subsequent intense phase of infrastructural investment, followed by general economic expansion and a concomitant increase in accumulation. Therefore, it could also be fruitful to search for a long lasting continuous up and down cycle of super-hegemony. Thus, infrastructural investment cycles would be related to cycles of accumulation and cycles of hegemony in the world system. Are there also cumulative aspects of infrastructural investment that affect subsequent world system development? We incline to an affirmative answer. However, we do not believe that this cumulation necessarily takes place in or through a single "capital-imperialist" mode of production, and still less one based on the primary use of a political apparatus to exercise imperial political power for this accumulation, as apparently posited by Ekholm and Friedman (1982). Other competitive "economic" mechanisms operating within the very CPH and hegemonic structure of the world system can also further the process of cumulation in the world system. How did private and state investment interact in world system development? For instance, what is the role of private infrastructural investment in creating and sustaining the complex logistical interlinkages of the world system? To what extent does state infrastructural investment create and sustain the logistical interlinkages of the world system? How does the conjuncture and synchronization of phases among contemporary hegemonies affect the respective cycles of infrastructural investment? If we view the entire five or six millennia development of the world system as a unified cumulative continuum and seek to explain its most significant trends, cycles, and rhythms, based on an historical materialist political economy, then a "world system history" should follow. Such a world system history should not merely be a comparative history of the world or even a comparative history of world systems. An historical materialist world system history would regard class formation, capital accumulation, state formation, and hegemonic construction throughout the world system as being integral aspects of the one, cumulative, process of world historical world system accumulation and development. This history would not be Eurocentric, and should avoid any other form of centricism. A comprehensive world system history would be humanocentric. We mean humanocentric in two senses. One is that world history must encompass the structure and development of the system, which importantly determines the lives of all humanity, and not just a (self)selected part of it. Second, world (system) history should leave room for how people shape their own and world history. Most history is written top down by and/or for the victors in historical struggles. Of course, the hierarchical and center-periphery structure and mechanisms of social transformation in the system merit attention, as we have emphasized. However, human history and the world system itself also emerges out of multiple bottom up social movements and other struggles. Some were successful in their time and place. Many were defeated. Both intervened in forming and transforming world system history. More specifically, popular dissatisfaction and its socio-political expression helped shape and transform societies and empires from reform movements in ancient Sumer and peasant uprisings in "dynastic cycle" China to today. The scholarly difficulty of incorporating these social movements into a world system history is only exceeded by the political importance of doing so. Yet we must try; since it is the very structure and development of the world system, which (cyclically?) generates and continually regenerates the social (movement) and other struggles -- and vice versa.
