Project Summary

      Patterns of expanding state formation constitute a long-term evolutionary trend that will probably eventually result in the emergence of a single world state. The very nature of the expansion of political integration has itself evolved because new institutions that facilitate regional integration, cooperation and conflict have emerged.  Military conquest and the long-term interaction between sedentary agrarian empires and confederations of pastoral nomads came eventually to be replaced by a process of geopolitical and economic competition among states in a world that has increasingly been integrated by market exchange. In the last 200 years international governmental and transnational non-governmental organizations have emerged that constitute the first beginnings of world state formation, and the national states have been partially reconfigured as instruments of an increasingly integrated global elite. World state formation may be desirable because the problems created by human technological and social change are increasingly global in scope. But a world state will need to be legitimated in the eyes of a majority of the human population of the Earth and this means that democracy must be constructed on a global scale.  This proposed project will allow us to examine several probable future trajectories of global political integration based on models of growth, decline and systemic transformation that are developed by studying patterns of political integration in several regions over the past 3000 years.

The main purpose of the proposed project is to study and model the growth of states in selected regions of the world over the past 3000 years. In the nineteenth and twentieth centuries expansion and intensification of intercontinental interactions has been called globalization. But earlier regional systems also exhibited similar waves of “globalization,” albeit on a smaller spatial scale, and these waves of network expansion and contraction, punctuated by occasional huge jumps in the scale of networks, eventually led to the formation of the modern global social system. This project will study the spatial nature of interaction networks over time and the relationship between these networks and the growth decline/phases of cities and states. The three-year project will develop, parameterize and test models of social change using newly upgraded estimates of the sizes of cities and states, climate change, trade routes, and warfare.

Intellectual Merit

The project will develop a new theoretical synthesis based on Peter Turchin's (2003) model of the dynamics of agrarian state growth and decline, network theory, a population pressure and ecological model, and explanations of the rise and fall of modern hegemons. The "agents of change" focus will test the hypothesis of “semiperipheral development” – the idea that that it has mainly been semiperipheral societies that have expanded networks, made larger states, and innovated and implemented new techniques of power and new productive technologies that have transformed the very logic of social change. 

Broader Impacts

The products of the project will help to inform scholars and policy-makers about long-run patterns of historical social evolution and their implications for the human future, especially world state formation.  The World Historical Systems Time Map will be a spatio-temporal web-enabled data set in a standardized interoperable format that will be useful for scholars and students all over the world.  The elaboration of cooperative and coordinated global policies for dealing with the emergent problems of the twenty-first century will be usefully informed by understanding the probable trajectories of international political integration.

 

Project Description   

 

This project will study the spatial nature of interaction networks over time and the relationship between these networks and the growth decline/phases of cities and states. The three-year project will develop, parameterize and test models of social change using newly upgraded estimates of the sizes of cities and states, climate change, trade routes, and warfare.  The project will develop a new theoretical synthesis based on Peter Turchin's (2003) model of the dynamics of agrarian state growth and decline, network theory, a population pressure iteration model and explanations of the rise and fall of modern hegemons. The "agents of change" focus will test the hypothesis of “semiperipheral development” – the idea that it has mainly been semiperipheral societies that have expanded networks, made larger states, and innovated and implemented new techniques of power and new productive technologies that have transformed the very logic of social change. The elaboration of cooperative and coordinated global policies for dealing with the emergent problems of the twenty-first century will be usefully informed by understanding the probable trajectories of international political integration.

 

Elements of the Project

      The project will be led by a sociologist, and population ecologist and an anthropologist. Its theoretical and empirical efforts combine demography and integrative ecology with a world historical approach to human social evolution. Thus it is truly interdisciplinary.

      The large temporal and spatial scope of this project is necessary to properly study how the dynamics of human macrosystems have evolved. This project will focus on building non-linear dynamic models, enhancing existing data, and testing the models with sophisticated new methods for social network and spatio-temporal analysis. The central intellectual merit of the project will be to develop dynamical models of the rise and fall of states over the past 3000 years in order to provide insights about the probable future trajectories of global state formation. We will begin with a demographic and ecological model of the growth and decline of land-based “tellurocratic” states followed by development of a model of the growth of “thalassocratic” maritime capitalist city-states. These models will then be combined to model the transition to the “modern” pattern of the rise and fall of capitalist hegemonic nation-states. We will also build and test a model of the interactions among world regions that can account for the East/West synchrony of growth/decline phases of cities and states discovered in earlier research. These models will help us to explain the human past and will have important implications for the future of global governance because the causes of past political expansion and of future state formation will be modeled.  Using city and regional population sizes and the territorial sizes of states and empires as the main indices of civilizational rise and fall, the project will model the interacting effects of population growth, environmental degradation, resource use, migration, and the growth and decline of cities and empires. The project will also model the interactions of regional systems with one another. Interregional trade, warfare, incursions and disease vectors are important factors that have affected social change in regional interaction networks.

      The products of the project will help to inform scholars and policy-makers about long-run patterns of historical social evolution allowing them to better anticipate and confront problems of sustainability, global inequality and social conflict that are likely to emerge in the 21st century.  The World Historical Systems Time Map will be a spatio-temporal web-enabled data set in a standardized interoperable format that will be useful for scholars and students of long-term social change all over the world.  The educational products of the project will inform scholars and students about the patterns of human social evolution and their interaction with natural systems.

      The data resource development of this project will focus on city and state sizes, trade routes and amounts, warfare, climate change, and epidemic diseases, and the classification of states and nomadic peoples as to their position in intersocietal hierarchies (core, periphery and semiperiphery). Using a multiple indicator measurement error approach, the project will estimate the values of important variables using proxy indicators.  The resultant data archive will include information on all the large cities and states since 1000 BCE in the targeted regions as well as data on climate change, trade, migration and incursions, warfare and population size estimates.

      The analyses will use GIS, spatio-temporal statistical methods, network analyses and structural equations modeling to test theoretical models. The temporal framework of the project is 3000 years (from 1000 BCE to the present), including the period of the agrarian empires and preindustrial cities as well as the modern global system. The spatial focus is four regions in Afroeurasia from 1000 BCE to 1500 CE, and then the whole globe over the past 500 years.

Macrosocial Systems

      Macrosocial systems (or “world-systems”) are systems of societies that are strongly linked to one another by interaction networks (trade, alliances, warfare, migration and information flows). Thousands of years ago these were small regional affairs, but they have gotten larger, merged with one another and the big ones have engulfed smaller ones. This process of network expansions has eventuated in the single global macrosocial system of today. One important meaning of the globalization is the expansion and intensification of large-scale interaction networks. At the same time that macrosystems have become spatially larger, the societies and intersocietal systems that make them up have become more complex and hierarchical. And the dynamics of systemic expansion may have qualitatively changed as new institutions, especially markets and financial systems, have emerged and become predominant.

      The patterns of expansion and incorporation can be traced by examining changes in the spatial extent of interaction networks (Chase-Dunn and Hall 1997).  Figure 1 illustrates the spatiotemporal history of the political/military network (PMN) that emerged first in Mesopotamia 5000 years ago.

Figure 1:  5000 Year Emergence of the Central System (adapted from Wilkinson 1987)

 

The processes of expansion and increasing complexity have not produced a smooth upward trend in which the originally less complex and hierarchical areas became increasingly more complex. Rather social change has been characterized by uneven development in both space and time. Original areas where leading edge developments have emerged eventually lost out to new regions where unprecedented levels of complexity and hierarchy developed. Temporal cycles of expansion and political centralization were punctuated by occasional upward sweeps to new higher levels – a stair-step pattern.

All hierarchical macrosystems, even including those based on chiefdoms (Anderson 1994) and early states (Marcus 1998) experience a sequence of the rise and fall of large polities – a cycle of centralization and decentralization of political power. This is known in state-based systems as the rise and fall of empires. In the modern macrosystem of the last few centuries a similar (but also different) phenomenon can be seen in the rise and fall of hegemonic core states such as Britain in the nineteenth century and the United States in the twentieth century.  Interaction networks also expand and contract in a pattern that we can call pulsation. This expansion and intensification of large interaction networks corresponds to one important aspect of what is called “globalization” in the modern world-system.  The recent wave of global trade and investment integration since World War II was preceded by a globalization phase during the last half of the nineteenth century that attained nearly the same degree of worldwide connectedness (Chase-Dunn, Kawano and Brewer 2000).

These cyclical processes (rise and fall; pulsation) must be modeled in order to understand the more rare instances in which new higher levels of integration and hierarchy have emerged. Both cities and empires in Eastern and Western Asia have been found to grow and decline synchronously from 500 BCE until 1500 CE, but South Asia did not follow this pattern (Chase-Dunn, Manning and Hall 2000; Chase-Dunn and Manning 2002).

The four regional intersocietal systems we propose to study before 1500 CE are: 1. West Asia/Mediterranean; 2. East Asia; 3. South Asia; and 4. Central Asia. Except for Central Asia we will focus on the settlement systems surrounding the largest cities in each region. In Central Asia we will focus on cities and the main areas inhabited by nomadic pastoralists. After 1500 CE we will study these same regions plus Europe and the Americas.

 

The dynamics of agrarian states

      The primary resources in agrarian economies are land and people. Geopolitical models, such as those developed by Randall Collins and Robert Hanneman (Collins 1995, Hanneman et al. 1995), postulate that state power is directly related to the amount of territory and population that the state controls. This functional dependence leads to positive-feedback dynamics: a state that expands territory increases its power, which in turn enables it to expand more, and so on (a classical example is the Roman expansion under the late republic). However, eventually the ability of the state to extend its territorial control becomes limited by the difficulty and expense of projecting power across space. This connection between the state size and “logistical loads” is sometimes referred to as the imperial overstretch principle (Kennedy 1987).

      Spatial location is important for explaining the geopolitical trajectories of states. Historians noticed long ago that new, aggressive states that have an excellent chance to grow into a large empire tend to arise on the marches (edges) of old empires (McNeill 1963). Within the comparative world-systems perspective, this phenomenon is termed semiperipheral marcher conquest, in which a new state from out on the edge of the circle of old states conquers all (or most) of the states in the old core region to form a “universal empire” (Chase-Dunn and Hall 1997). The geopolitical theory explains this empirical pattern by invoking the marchland position principle: states with enemies on fewer fronts expand at the expense of states surrounded by enemies (Collins 1995). However, a comprehensive empirical test on the European material during the first two millennia CE indicates that there is no statistical association between protected position of a region and the size of polity emerging from it (Turchin 2003). An alternative explanation is suggested by the observation that not all imperial marchlands or semiperipheries give birth to aggressively growing polities. It appears that incipient empires arise only in locations where pre-existing imperial boundaries coincide with intense cultural, or ethnic, frontiers. During the last two millennia the most common symbolic markers demarcating such metaethnic frontiers (the prefix meta indicates the intensity of ethnic difference across the frontier) have been based on world religions (thus, the most common variety in the European context are the Christian-Muslim frontiers). Metaethnic frontiers are zones where groups come under enormous pressure, and where ethnocide or even genocide, but also ethnogenesis, commonly occur (Hall 2000). Intense intergroup competition eventually results in one group with high internal cohesion absorbing other ethnically similar groups, and in the process constructing the core of a rising empire (Turchin 2003).

      An implicit assumption of the geopolitical model discussed above is that geopolitical resources, land and people, come as a package. In reality, however, the population of a state can grow (or decline) without corresponding addition or loss of territory. Growing population density initially increases geopolitical power of the state, because there are more taxpayers and recruits for the army. However, population growth in excess of the productivity gains of the land has deleterious effects on social institutions (Goldstone 1991). It leads to persistent price inflation, falling real wages, rural misery, and urban migration; an increased number of aspirants for elite positions and intense intra-elite competition; and spiraling state expenses due to inflation and expanding real costs, since armies and bureaucracies grow together with population. As all these trends intensify, the state goes into bankruptcy and loses military control. Elite movements of regional and national rebellion and a combination of elite-mobilized and popular uprisings lead to the complete breakdown of central authority (Goldstone 1991). In turn, state collapse and ensuing sociopolitical instability cause higher death and emigration rates, lower birth rates, and negative effects on the productive infrastructure such as irrigation canals and flood-control dams.[1] Models incorporating both the effect of population growth on state stability, and the feedback from state instability to population decline suggest that we should observe long-term demographic-political cycles, with periods of roughly two-three centuries (Turchin 2003).

 

Theories of Rise and Fall

      Complex interchiefdom systems experienced a cycle in which a single paramount chiefdom became hegemonic within a system of competing polities by conquering adjacent chiefdoms (D.G. Anderson 1994; Kirch 1984).[2] Once states emerged within a region they went through an analogous cycle of rise and fall in which a single state became hegemonic and then declined. Eventually most of these systems of states (interstate systems), experienced the phenomenon of semiperipheral marcher conquest in which a new state from out on the edge of the circle of old states conquered all (or most) of the states in the old core region to form a “universal empire”.[3]

      These patterns repeated themselves in several world regions for thousands of years, with occasional leaps in which a semiperipheral marcher state conquered larger regions than had ever before been subjected to a single power (e.g. Assyrian Empire, Achaemenid Persia, Alexandrian Empires, the Chin and Han Dynasties, Roman Empire, the Islamic Caliphates, the Aztec and Inca Empires, the Manchu Dynasty in China). During the Bronze and Iron Age expansions of the tributary empires a new niche emerged for states that specialized in the carrying trade among the empires and adjacent regions. These semiperipheral capitalist city states were usually “thalassocratic”  entities that used naval power to protect sea-going trade (e.g. the Phoenician city-states, Venice, Genoa, Malacca), but Assur on the Tigris, the “Old Assyrian city-state and its colonies,” (Larsen 1976) was a land-based example of this phenomenon that relied mainly upon donkey caravans for transportation. The semiperipheral capitalist city-states did not typically conquer other states[4] to construct large empires, but their trading and production activities promoted regional commerce and the emergence of markets within and between the tributary states.

      With the eventual rise of Europe and intensified capitalism a modification of the old pattern of semiperipheral marcher conquest appeared. In the European interstate system the semiperipheral marcher states were outdone by a new breed of capitalist nation-states. These capitalist hegemons established primacy in the larger system without conquering adjacent core states, and so the core remained multicentric despite the continued rise and fall of hegemonic core powers. Imperialism over adjacent states was reorganized as colonial empires in which each core state had its own distant peripheral colonies – the European domination of peoples in Africa, Asia and the Americas. The efforts by some modern core powers to conquer their neighbors were defeated by coalitions that sought to reproduce a multistate structure among core states. Thus the oscillation between “universal state” and “interstate system” came to end and was replaced by the rise and fall of hegemonic core powers. The hegemonic sequence of the modern interstate system alternates between two structural situations as hegemonic core powers rise and fall: hegemony and hegemonic rivalry. This was the new form of the process of rise and fall.

      The Westphalian interstate system, in which the sovereignty of separate and competing states is institutionalized by the right of states to make war to protect their independence, has become a taken for granted institution in the modern world-system. Historians of international relations (e.g. Kennedy 1987) and theorists of international relations (e.g. Waltz 1979) have come to define this situation as a natural state of being. Authors with greater temporal depth (e.g. Wilkinson 1988, 1999) have argued that the peculiar resistance of the modern interstate system to the emergence of a universal state by means of conquest has been the result of an evolutionary learning process unique to modern Europe in which states realized that in order to protect their own sovereignty they should band together and engage in “general war” whenever a “rogue state” threatens to conquer another state.

      A rather different explanation of the modern transition from the pattern of semiperipheral marcher state conquest to the rise and fall of hegemonic core powers points to the emergent predominance of capitalist accumulation in the European-centered interstate system.  Once capitalism had become the predominant strategy for the accumulation of wealth and power it partially supplanted the geopolitical logic of institutionalized political coercion as a means to accumulation. Powerful capitalist core states emerged that could effectively prevent semiperipheral marcher states from conquering whole core regions to erect a “universal state.” The first capitalist-nation state to successfully do this was the Dutch republic of the seventeenth century.

 

Modern Rise and Fall

      There are several important ways in which explanations of modern rise and fall are different from one another. One important distinction is between the functionalists (who see emergent global hierarchies as serving a “need for global order,”) and conflict theorists (who dwell more intently on the ways in which hierarchies serve the privileged, the powerful and the wealthy). The term “hegemony” usually corresponds with the conflict approach, while the functionalists tend to employ the idea of “leadership,” though several analysts occasionally use both of these terms (e.g. Arrighi and Silver 1999). Another difference is between those who stress the importance of political/military power vs. what we shall call “economic power.” This issue is confused by disciplinary traditions (e.g. differences between economics, political science and sociology). Most economists entirely reject the notion of economic power, assuming that market exchanges occur among equals. Most political scientists and sociologists would agree that economic power has become more important than it formerly was.  Some of the literature on recent globalization goes so far as to argue that states and military organizations have been largely subsumed by the power of transnational corporations and global market dynamics (e.g. Ross 1995).

      The three most important approaches to theorizing modern hegemony are those of Wallerstein (1984, 2002), Modelski and Thompson (1994); and Arrighi (1994). Wallerstein defines hegemony as comparative advantages in profitable types of production. This economic advantage is what serves as the basis of the hegemon’s political and cultural influence and military power. Hegemonic production is the most profitable kind of core production, and hegemony is just the top end of the global hierarchy that constitutes the modern core/periphery division of labor. Hegemonies are unstable and tend to devolve into hegemonic rivalry.

      Wallerstein sees a Dutch seventeenth century hegemony, a British hegemony in the nineteenth century and U.S. hegemony in the twentieth century.  He perceives three stages within each hegemony. The first is based on success in the production of consumer goods; the second is a matter of success in the production of capital goods; and the third is rooted in success in financial services and foreign investment stemming from the institutionalized centrality of the hegemon in the larger world-system.

      George Modelski and William R. Thompson (1994) contend that the world needs order, and world powers rise to fill this need.  Such powers rise on the basis of economic comparative advantage in newly leading industries, which allow them to acquire the resources needed to win wars among the great powers and to mobilize coalitions that keep the peace. World wars are the arbiters that function as selection mechanisms for global leadership.  But the comparative advantages of the leaders diffuse to competitors and new challengers emerge. Successful challengers are those that ally with the declining world leader against another challenger (e.g. the U.S. and Britain against Germany).

      Giovanni Arrighi’s (1994) The Long Twentieth Century employs a Braudelian approach to the analysis of what he terms “systemic cycles of accumulation.” Arrighi sees hegemonies as successful collaborations between finance capitalists and wielders of state power. His tour of the hegemonies begins with Genoese financiers who allied with Spanish and Portuguese statesmen to perform the role of hegemon in the fifteenth century. In Arrighi’s approach the role of hegemon itself evolves, becoming more deeply entwined with the organizational and economic institutional spheres that allow for successful capitalist accumulation. He sees a Dutch hegemony of the seventeenth century, then a period of contention between Britain and France in the eighteenth century, and a British hegemony in the nineteenth century, followed by U.S. hegemony in the twentieth century.

      A distinctive element of Arrighi’s approach is his contention that profit making from trade and production becomes less profitable toward the end of a ‘systemic cycle of accumulation” and so big capital increasingly focuses on financial manipulations.  Arrighi’s approach is compatible with the idea that new lead industries are important for the rise of a hegemon, but he sees the economic activities of big capital during the declining years in terms of speculative financial activities. These latter often correspond with a period of “growth” in which incomes are rising during a latter-day belle époque of the systemic cycle of accumulation. But this period of accumulation is based on the economic power of haute finance and the centering of world markets in the global cities of the hegemons rather than on their ability to produce real products that people will buy, and so these belle époques are unsustainable bubbles that are followed by decline.

      The main task of the proposed project will be to develop dynamical models of the rise and fall of states and the occasional upward sweeps in which newly emergent states break through the extant ceiling of state size to produce a much larger polity than has ever existed before (See Figure 2). We will begin with a demographic and ecological model of the growth and decline of land-based “tellurocratic” states. Then we will develop a model of the growth of “thalassocratic” maritime capitalist city-states. These models will then be combined to model the transition to the “modern” pattern of the rise and fall of capitalist hegemonic nation-states.

 

Figure 2: Rise and Fall with Upward Sweeps of State Size

 

The basic model

Figure 3 (below) illustrates our several hypotheses about the causal relations among the main variables that cause city and empire growth. At the top of Figure 3 is Population Growth. Procreation is socially regulated in all human societies, but despite this there has been a long-run tendency for population to grow.  Population Growth leads to Intensification, defined by Marvin Harris (1977:5) as “the investment of more soil, water, minerals, or energy per unit of time or area.”  Intensification leads to Environmental Degradation as raw material inputs become scarcer and the unwanted byproducts of human activity (pollution, etc.) modify the surrounding environment.  Together Intensification and Environmental Degradation lead to rising costs in terms of labor time needed to produce the food and raw materials that people need, and this condition is called Population Pressure.  In order to feed more people, farmers must use more marginal land because the best soils have become degraded. Or deer hunters must travel father to find their quarry once deer have become depleted in nearby districts. Thus the cost in time and effort of producing a given amount of food increases (Boserup 1965; 1981). Some resources are less subject to depletion than others (e.g. fish compared to big game), but increased use usually causes rising costs. Other types of environmental degradation are due to the side effects of production, such as the build-up of wastes and pollution of water sources. These also increase the costs of continued production or cause other problems.

As long as there were available lands to occupy, the consequences of population pressure led to Migration. And so humans populated the whole Earth. The costs of Migration are a function of the availability of desirable alternative locations, moving costs, and the effective resistance to immigration that is mounted by those who already live in these alternative locations.

Circumscription (Carneiro 1970) occurs when the costs of leaving are higher than the costs of staying. This is a function of available lands, but lands are differentially desirable depending on the technologies that the migrants employ. Generally people have preferred to live in the way that they have lived in the past, but Population Pressure or other push factors can cause them to adopt new technologies in order to occupy new lands.

 

Figure 3: Demographic and Environmental Causes of City and State Growth[5]

 

 The factor of resistance from extant occupants is also a complex matter of similarities and differences in technology, social organization and military techniques between the occupants and the groups seeking to immigrate. Circumscription increases the likelihood of higher levels of Conflict in a situation of Population Pressure because, though the costs of staying are great, the exit option is closed off.  This can lead to several different kinds of warfare, but also to increasing intrasocietal struggles and conflicts (civil war, class antagonisms, etc.)  A period of intense conflict tends to reduce Population Pressure if significant numbers of people are killed off. And some systems get stuck in a vicious cycle in which warfare and other forms of conflict operate as a demographic regulator, e.g. the Marquesas Islands (Kirch 1991). This cycle corresponds to the path that goes from Population Pressure to Migration to Circumscription to Conflict, and then a negative arrow back to Population Pressure. When population again builds up another round of heightened conflict knocks it back down again..

      Under the right conditions a circumscribed situation in which the level of conflict has been high will be the locus of the emergence of more hierarchical institutions, larger states and larger cities. Carneiro (1970) and Mann (1986) contend that people will tend to run away from state-formation if they can in order to maintain autonomy and equality. But circumscription prevents exit, and exhaustion from prolonged or extreme conflict may make subservience to a new state the least bad alternative. It is often better to accept a king than to continue fighting. And so kings (and big men, chiefs and emperors) emerged out of situations in which conflict had reduced the resistance to centralized power. This is quite different from the usual portrayal of those who hold to the functional theory of stratification.  The world-system insight here is that the newly emergent elites most often come from regions that have been semiperipheral. These larger states build new or expand existing cities. 

Intersocietal systems are often structured as hierarchies in which powerful core states dominate and/or exploit less powerful semiperipheral and peripheral peoples. And yet some semiperipheral agents of change are unusually able to put together effective campaigns for erecting new levels of hierarchy.[6] This may involve both innovations in the “techniques of power” and innovations in productive technology (Technological Change). Newly emergent elites often implement new production technologies as well as new waves of intensification. This, along with the more peaceful regulation of access to resources organized by the new elites, creates the conditions for a new round of Population Growth, which brings us around to the top of Figure 3 again. Female education and involvement in the world of work outside the household lowers the birth rate, and many countries in the contemporary world have stable population sizes, but the world as a whole has not yet reached that point and so the iteration model is still working. At some humans are likely to reach a stable population maximum, and the iteration model will need to be greatly modified to explain subsequent development.

The emergence of regional market exchange and states specializing in trade articulate changes in intensification, environmental degradation and population pressure with technological change, and so the mechanisms at the bottom of the model in Figure 2 are by-passed at least temporarily until population growth is so great that these articulations are overwhelmed. Then the process once again shifts toward greater conflict.

City growth.  The growth of cities, a major component of the anthropogenic built environment, is affected by multiple factors.  One important factor is demographic change.  In the agrarian era cities were population sinks, and relied on immigration from rural areas to sustain themselves. Rural population growth exacerbated this “sink” effect. When rural population increased beyond a certain threshold, rural areas suffered from an excess of labor, prompting migration to the cities. Such periods were usually accompanied by a flowering of crafts, because labor was cheap, and elites, enjoying greater returns from agriculture (due to high rents) tended to spend some of their wealth on the products of artisan labor. On the other hand, low real wages meant that an increasing proportion of the urban population was living below the subsistence level. As a result, urban mortality rates tended to rise, and birth rates to decline.

      Another important factor affecting city growth is technological development, which leads to greater agricultural productivity and a larger proportion of population living in the cities.  Improvements in sanitation and health did not greatly affect the urban mortality rate until the middle of the nineteenth century.

Imperial expansion.  So far we have addressed the nonspatial aspects of the modeled system  – either acting in a local fashion (population growth, agricultural intensification) or, conversely, in a global fashion (global climate change, millennial growth of technological knowledge). What makes a model explicitly spatial, however, are processes that connect various localities, and whose strength declines with distance. One such mechanism is the spatial expansion of empires resulting from conquest of adjacent territories. The first, and obvious, factor is the size of the population controlled by the empire. However, the effect of population size on military strength is nonlinear.  One of the important factors affecting imperial conquest is the strength of the state (S), since wealthy empires can raise large armies, purchase expensive equipment, and sustain armies in the field for lengthy periods of time. Thus, an empire during the unfavorable phase of the demographic cycle (when it suffers from fiscal crisis) has great difficulties in financing war operations. These are periods when empires are extremely vulnerable to adversary empires, or to barbarians. Other mechanisms affecting warfare that we will investigate are changes in military technology and the military advantages of developed by Central Asian steppe nomads during a long period within the project time frame.

      An important spatial process affecting imperial growth is the logistical aspect of the ability of the state to project its power over distance. This theory has been well developed as a result of work by Randall Collins (1999) on geopolitics (see also Hanneman 1995 and Turchin 2003b). We will model geopolitical processes by focusing on spatial units located on or near the boundary between adjacent states, and calculating the power that each state can bring to bear on these spaces. In the simplest formulation, the power of State 1 delivered to square with coordinate x,y  is:

 

P1(x,y,t) = S1 exp[-d1(x,y)/h]

 

where S1 is the resources of State 1 and d1 is the distance from the center of State 1 to the spatial unit x,y. Parameter h modulates how fast power diminishes with distance (and its units are km). P2(x,y,t) is calculated analogously. The relative values of P1 and P2 determine whether State 1 or State 2 will conquer the unit. For example, a simple rule is that the probability of the square going to State1 is equal to P1/(P1+P2), and vice versa.

      The logistics parameter h can be made a function of the local geography. It is easier to project power across flat space than across mountains. We will also investigate the effect of a multiplier that will reflect the military technology available to each state, or reflect the difference between, say, nomads and settled polities.

Core/periphery status.  Examination of the hypothesis that semiperipheral societies are frequently the loci of change agents that expand and transform institutional structures will require coding the position of societies in core/periphery hierarchies. Fortunately David Wilkinson (1991) has already produced a coding of sedentary societies into core, peripheral and semiperipheral categories. Our plan is to improve upon Wilkinson’s work by distinguishing between different kinds of semiperipheries and by including nomadic peoples.

Causes of East/West Synchrony

One important product of our modeling project will be to determine the causes of a fascinating synchrony that emerged between East Asia and the distant West Asian/Mediterranean region in the growth/decline phases of cities and empires, but did not involve the intermediate South Asian region. Studies have used data on both city sizes and the territorial sizes of empires to examine the hypothesis that regions distant from one another were experiencing synchronous cycles of growth and decline (e.g. Chase-Dunn, Manning and Hall 2000; Chase-Dunn and Manning 2002).  Frederick Teggart’s  (1939) path-breaking world historical study of temporal correlations between events on the edges of the Roman and Han Empires argued the thesis that incursions by Central Asian steppe nomads were the key to East/West synchrony. A study of city-size distributions in Afroeurasia (Chase-Dunn and Willard 1993; see also Chase-Dunn and Hall 1997: 222-223) found an apparent synchrony between changes in city size distributions and the growth of largest cities in East Asia and West Asia-North Africa over the period from 500 BCE to 1500 CE.  That finding led to a study of the territorial sizes of empires, which found a similar synchrony (Chase-Dunn, Manning and Hall 1999). [7] Plausible causes of these synchronies are climate change, epidemics, trade cycles, and the incursions of Central Asian steppe nomads.

 
Global State Formation

      The scientific literature on future global state formation has mainly consisted of linear or quadratic extrapolations of several different cross-temporal empirical indicators. Robert Carneiro’s (1978) original study quantified the long-term decline in the number of autonomous polities on Earth to predict an emergent world state in about 1000 years from the present. Earlier studies by Raul Naroll (1967) and Louis Marano (1973) had used the territorial sizes of states for a similar purpose. Peter Peregrine, Melvin Ember and Carol R. Ember (2004) employ a similar extrapolation approach that uses indicators based on codings of archaeological evidence.  Based on an indicated quadratic curve over the past 12,000 years, they predict the emergence of a global state by CE 5000.

      The careful study of the territorial sizes of the largest empires over the past 3000 years by Rein Taagepera (1978, 1997) shows that the largest states in different regions tended to rise and fall with occasional radical upward swings. Taagepera observes that the median duration of large polities at more than half their peak size has been around 130 years. He also notes that polities that expand fast are somewhat shorter-lived than polities that expand more slowly. And he reports that three sudden increases in polity sizes occurred around 3000 BCE, 600 BCE and CE 1600. [8]

 

Upward Sweeps

      The question of the timing of upward sweeps to new levels is entirely germane to the problem of modeling global state formation. So also is the issue of how unusually large states have been formed in the past. Upward sweeps have mainly been instances of a semiperipheral marcher state conquering and unifying adjacent older core states and nearby peripheral areas. So conquest has been the main mechanism of large-scale political integration. But the pattern of hegemonic rise and fall in the modern world-system has been different. The most powerful states, the hegemons (the Dutch, the British and the United States), have fought semiperipheral challengers (e.g. Napoleonic France and Germany) to prevent the emergence of a core-wide empire. We contend that this is because the hegemons are the most capitalist states in the system, the ones for whom economic success is most closely tied to the ability to make superprofits on the technological rents that return from new lead technologies. 

      Only during hegemonic decline have the modern capitalist hegemons shown a tendency toward “imperial overreach” in which their military power is employed in a last ditch effort to prop up a declining economic hegemony. These efforts have not been successful, and a new hegemon only emerges after a period of hegemonic rivalry and world war. This is a method of choosing “global leadership” that we can no longer afford to employ, and so the issue of institutions that can peacefully resolve the struggle for hegemony is of the first importance for our very survival as a species.

      The approach that we propose is to model the main causes of state formation and upward sweeps taking into account the ways in which the basic processes have been altered by the emergence of new institutions.  We will elaborate and improve upon the recent work of Robert Bates Graber (2004).  Graber develops both an ahistorical and an historical population pressure model of political integration. His ahistorical model is a very simplified version of the iteration model displayed in Figure 3 above that includes population growth rates and the number of independent polities. Graber’s historical model takes account of the emergence of the League of Nations and the United Nations as our approach will do. But we add the rise and fall cycle, the emergence of markets and capitalism, and the growth of other international political organizations and non-governmental organizations to our model of political globalization.

      The main political structure of the modern world-system has been, and remains, the international system of states as theorized and constituted in the Peace of Westphalia. This international system of competing and allying national states was extended to the periphery of the modern world-system in two large waves of decolonization of the colonial empires of core powers. The modern system already differed from earlier imperial systems in that its core remained multicentric rather than being occasionally conquered and turned into a core-wide empire. Instead, empires were organized as distant peripheral colonies rather than as conquered adjacent territories. Earlier instances of this type of colonial empire were produced by thallasocratic states, mainly semiperipheral capitalist city-states that specialized in trade. In the modern system this form of colonial empire became the norm, and the European core states rose to global hegemony by conquering and colonizing the Americas, Asia and Africa in a series of expansions (see Figure 4). The international system of sovereign states was extended to the colonized periphery in two large waves of decolonization (see Figure 4). After a long-term trend in which the number of independent states on Earth had been decreasing, that number rose again with decolonization and the core states decreased in size when they lost their colonial empires.

Extension of the State System to the Periphery

      The decolonization waves were part of the formation of a global polity of states. And one of the decolonized regions became “the first new nation,” and eventually rose to hegemony to become the largest hegemon the modern system has seen – the United States.  The doctrine of the national self-determination, long a principle of the European state system, was extended to the periphery.

Figure 4: Waves of colonization and decolonization based on Henige (1970)

      This multistate system has also experienced waves of international political integration that began after the Napoleonic Wars early in the nineteenth century. Britain organized a “Concert of Europe” (Jervis 1985) that was intended to prevent future French revolutions and Napoleonic adventures. During the middle of the nineteenth century a large number of specialized international organizations emerged such as the International Postal Union (Murphy 1994) that underwrote the beginnings of a global civil society that included more than elites, and this network of transnational voluntary associations grew much larger during the most recent wave of economic globalization since World War II.   After World War I the League of Nations was intended to provide collective security, though it was weakened by the failure of the United States to join. After World War II the United Nations became a proto-world-state, the efficacy of which has waned and waxed since then. The system of national states is being slowly overlain by global and regional transnational political organizations that blossom after periods of war and during periods of economic globalization.

      Our historical model will add marketization, decolonization, new lead technologies, the rise and fall of hegemons, and the rise of international political organizations to the population pressure model in order to forecast future trajectories of global state formation. And we will assemble empirical data for the last two hundred years on the trend toward global political integration in order to parameterize our models. This will allow us to examine how changing assumptions about the relationships among variables will affect probable future trajectories of international political integration. Our conceptualization of the cyclical nature of many processes will allow us to consider how downward plunges and possible collapses might affect the probable trajectories of global state formation.

      We will also take into account the structural differences between recent and earlier periods. For example, the period of British hegemonic decline moved rather quickly toward conflictive hegemonic rivalry because economic competitors such as Germany were able to develop powerful military capabilities. The U.S. hegemony has been different in that the United States ended up as the single superpower after the decline of the Soviet Union. Economic challengers (Japan and Germany) cannot easily use the military card because they are stuck with the consequences of having lost the last World War. This, and the immense size of the U.S. economy, will probably slow the process of hegemonic decline down relative to the speed of the British decline (Chase-Dunn, Jorgensen, Reifer and Lio, Forthcoming). [9]

      Our modeling of the global future will also consider changes that have occurred in labor relations, urban-rural relations, the nature of emergent city regions, and the shrinking of the global reserve army of labor (Silver 2003).         

TheTrajectory of Political Globalization

      We conceptualize political globalization analogously to our understanding of economic globalization as the relative strength and density of larger versus smaller interaction networks and organizational structures.  Much has been written about the emergence and development of global governance and many see an uneven and halting upward trend in the transitions from the Concert of Europe to the League of Nations and the United Nations toward the formation of a proto-world state. The emergence of the Bretton Woods institutions (the International Monetary Fund and the World Bank) and the more recent restructuring of the General Agreement of Tariffs and Trade as the World Trade Organization, and the visibility of other international fora (the Trilateral Commission, The Group of Seven [Eight]; the World Economic Forum, the World Social Forum meetings, etc.) support the idea of emerging global governance.  The geometric growth of international non-governmental organizations (INGOs) is also an important phenomenon of global governance and the emergence of global civil society (Murphy 1994; Boli and Thomas 1999).

      As we have discussed above, all world-systems go through cycles of political centralization and decentralization with occasional leaps toward new and higher levels of political integration (Chase-Dunn and Hall 1997). In the modern world-system the cycle for the last 400 years has taken the form of the rise and fall of hegemonic core states. Some claim that the hegemonic sequence is now morphing into a new structure of core condominium (Goldfrank 1999).  We intend to study both the hegemonic sequence and emerging global governance. While these might be combined into a more general concept of political globalization, we contend that it is important to keep them separate because hegemonic rise and fall is an old feature of the world-system, whereas political globalization is arguably much more recent.  Political globalization can be analytically reduced to the question of the relative strength of larger vs. smaller political and military organizations (including also the functionally “economic” ones (IMF, World Bank, WTO) mentioned above.[10]

Data Development, Measurement Strategies and Units of Analysis           

This project will develop a World Historical System Time Map using an optimalized Afroeurasian cartographic grid that includes the focal regions we are studying. We will establish an Internet Collaboratory website. This will enable us to share access to the joint products of our research and to update modeling and data enhancements easily with all the project participants.

The project will develop programs to directly link the spatio-temporal database with our simulation models and statistical analyses, and to move modeling results back into the spatio-temporal format for visualization of modeling results. We will produce a relational database that is in an interoperable format to be linked with digital gazetteers and libraries such as the Alexandria Digital Library and the Electronic Cultural Atlas Initiative.

The basic strategy is to use statistical analyses of urban growth and changes in the territorial size of empires over the last three thousand years to parameterize our models. This will involve utilizing and extending three existing compilations of data: Tertius Chandler's (1987) Four Thousand Years of Urban Growth, George Modelski’s (2003) World Cities, -3000-2000 and Rein Taagepera's (1978a; 1978b; 1979; 1986; 1997) studies of the territorial sizes of empires.

We have developed a plan for enhancing these datasets on city populations and locations, the territorial sizes and geographical boundaries of states and empires, power configurations of interstate systems, climate change indicators, warfare, trade fluctuations, migrations and incursions. Using these data we will construct several different kinds of measures (e.g. city size distributions, empires size distributions) and will utilize sophisticated methods for splicing earlier, poorer indicators with later, better ones.

Units of Analysis

      Our spatio-temporal database will code the locations of events, settlements, polity boundaries, wars, epidemics and climate change indicators. We will use three different approaches to the problem of units of comparison for our statistical analyses:

1.      single states;

2.      political/military networks (which change their sizes over time because of expansion),

3.      and constant regions (East Asia; South Asia, Central Asia; West Asia/Mediterranean; and (after 500 BP) North and South America.

Using both political/military networks (2) and constant regions (3) will allow us to crosscheck our results to see if our way of bounding “cases” affects inferences about causal relations.

Model Testing

      We plan to test portions of our models using structural equations modeling (SEM) and path analysis. Our data sets will have a pooled-cross-section and time-series (panel) structure that can be used for the estimation of structural equation models.  For example, a city’s population size at any t+1 will be modeled as a linear additive function of its size at t, plus the magnitude of trade inflows to the city at t, and the political centrality of the city at t.  The error structures of such models are relatively complex, owing to both the pooled cross-sectional and time-series design, and to the geographical or network embeddedness of cases, but econometric modeling approaches to such problems are well understood. We will test hypotheses about the causes of rise/fall and synchrony with multiple time series analysis across PMNs and regions with attention to the need to detrend variables and problems of temporal autocorrelation.

      There is a single size distribution of political/military organizations in the modern world-system. We will operationalize three different parts of this size distribution, as well as the whole thing.  Our conceptualization of political globalization will be analogous to our understanding of economic globalization – a ratio of the size and importance of global and international organizations vs. the sum of size and importance of national (and multinational) states.  But we will also operationalize the hegemonic sequence by examining changes in the distribution of economic and military power among the core states using the research of Modelski and Thompson (1996).  And we will study the changing shape of the whole system of states as well, taking into account the processes of colonization and decolonization (Bergesen and Schoenberg 1980), the incorporation of the peripheral and semiperipheral regions into the interstate system, and changes in the distribution of economic and political/military power in the whole system of states.  We will also combine political globalization, hegemonic rise and fall, and state power stratification into a single overall measure of the distribution of power among state and proto-state institutions. This latter we will call “overall global political/military inequality.”  

Education Activities    

      Involvement in this project will provide to graduate and undergraduate participants an advancement of learning in both an individual and a social sense, and will encourage the students to become generalists with a capacity to conduct their own research as well as to move easily into more advanced doctoral or professional study of global processes.  We will train the graduate and undergraduates working on this research project to do interdisciplinary non-linear modeling and comparative research. They will be exposed to the process of solving problems and moving research forward by being involved in the weekly meetings conducted with the PIs and other advisors who play a part in the project. Students will gain interdisciplinary data analysis and modeling skills and will be encouraged to collaborate in the writing and presentation of scholarly research papers for professional meetings and the development of web-accessible materials stemming from our project.

 

      Though a major effort will be devoted to building and testing mathematical models, this project will also upgrade existing data on key measures on the World Historical System Time Map.[11] This refreshed spatio-temporal relational database will be used to produce interpretive maps of the emergence of cultural complexity for high school and college classes.  Our data base construction and model building will benefit from the collaboration of GIS scientists from Environmental Sciences Research Institute (ESRI), a private industry developer of GIS software and provider of spatial analyses in Redlands, California. Graduate research assistants from our project will be encouraged to participate in summer internships at ESRI.

      A key element of this project is the development and publication of an educational web site based on our research and teaching. We will produce and make available to the world community an educational resource that contains products from our project that have been rewritten for use in high school and college courses. The title of this educational web site will be “Human Social Dynamics, Globalization and World State Formation.” This will include syllabi for interdisciplinary global studies courses, graphical representations of our data and modeling results, numerical geochronological datasets for use by students for statistical analyses, and working papers produced by our project. We will use the results of our data collection and analyses, and our World Historical System Time Map to produce animated maps of Afroeurasia and the Americas for presentation on our educational web site.  These will show where cities and empires rose and fell over the past 3000 years, how climate changed, and the emergence of trade routes, information flows, and warfare interactions and alliances. Our education web site will have versions in English, French, Mandarin, Russian and Spanish; and the graphical presentations will be of use to teachers all over the world.  These will be available for use in high school world history and global history courses as well as in college courses on environmental history, global studies, climate change, human ecology, comparative civilizations, social evolution, and geography.

 

Management Plan

      Realizing our model-building goals will require a concentrated and coordinated effort in collaboration with the data infrastructure effort. Assemblage of an integrated geo-chronological database will involve a great deal of coordinated labor. The Internet Collaboratory website will enable us to coordinate our efforts and to share access to the joint products of our research with our senior advisors and student researchers.  Statistical analyses to test causal propositions and fully operational complex models will be achieved only after a considerable amount of prior work, and will depend on the development of an interoperable knowledge system of spatially and chronologically tagged information, the World Historical System Time Map (WHSTM).

      The co-Principal Investigators are Christopher Chase-Dunn (Sociology, UCR), E.N. Anderson (Anthropology, UCR) and Peter Turchin (Ecology and Evolutionary Biology, University of Connecticut).  Chase-Dunn will carry out the overall administration of the project (with grants management help at UC Riverside). He will oversee the project’s Internet Collaboratory, and modeling of the causes of synchrony. Anderson will coordinate the enhancement of datasets and the development of the World Historical Systems Time Map. Turchin will build non-linear dynamic spatio-temporal mathematical models of the historical dynamics of state growth and decline, rise and fall, and upward sweeps in interstate systems. The project has 18 Advisors from the United States and China (see below).

      The Co-PIS at UC-Riverside and the University of Connecticut will oversee graduate and undergraduate research assistants. The evaluations of the project activities will be done by project participants in interaction with students and colleagues attending professional conferences until the final year. At the final working conference five experts in dynamical modeling and macrohistorical social science who have not participated in the project will prepare critiques of the penultimate version of our models for presentation at the conference.

Project Significance

The three-year project will develop new mechanism-rich spatio-temporal models of state formation, rise and fall and upward sweeps of state size.            This project will produce an integrated complex model of social change in interaction with the environment that will provide a quantitative understanding of the long-term dynamics of world historical development. The modeling and data-gathering efforts will provide important scientific interpretations of the long-run dynamics of interactions of the cultures and institutions developed by humans with the natural environment. The World Historical System Time Map is a geo-chronological database containing information on fundamentally important variables in a standardized format for other researchers as well as for teachers, students and decision makers. The project will produce and make available to the world community, through the educational web site "Human Social Dynamics, Globalization and World State Formation", an educational resource that contains products that have been rewritten for use in high school and college courses.

      The modeling of the dynamics of agrarian interaction networks will make it possible to compare these with the global interaction network that has emerged in the last two centuries in order to understand both the similarities and the differences. The educational products of the project will help to inform the next generation of scientists and world citizens about the patterns of social evolution and their implications for future global governance and the educational products of the project will help to inform scholars and students about the patterns of social evolution and their implications for human life on Earth in the coming decades. The products of this proposed effort will allow scientists, citizens and policy-makers to better anticipate and confront problems of sustainability and social conflict that are likely to emerge in the 21st century.  The project of global polity building will be informed by study of the conditions that will influence probable future trajectories of world state formation.

[1] Ecological degradation can also be part of the explanation of uneven development. As older core regions become deforested and soil-depleted more recently developed areas can come to have an advantage.

[2] D.G. Anderson’s (1994) excellent review of the anthropological literature on the rise and fall of chiefdoms uses the term “cycling” to refer to this phenomenon. Patrick Kirch’s (1984) model of the emergence of complex chiefdoms on Pacific islands implies that the marcher chiefs who manage to conquer adjacent polities and create a larger island-wide polity are frequently from junior lineages on less ecologically favorable regions of the island.

[3] There were a few instances in which new core-wide empires were formed by internal revolt (e.g. the Akkadian Empire) or conquest by peripheral marchers (e.g. the Mongol Empire), but by far the majority of new empires were the work of semiperipheral marcher conquests.

[4] The Assyrians later switched to the semiperipheral conquest strategy and created the largest contemporary empire in the world. Hannibal’s attempt to conquer Rome was a similar change from the semiperipheral capitalist city-state strategy to the semiperipheral marcher state strategy. The failure of his Carthaginian allies to send support at a crucial juncture (due to ambivalence regarding the road he was traveling) was the main reason why his extraordinary effort failed.

[5] This model is explained more fully in Chase-Dunn and Hall (1997: Chapter 6).

[6] This is the semiperipheral development hypothesis.

[7] Chase-Dunn and Manning (2002) have re-examined the city size data using constant regions rather than PMNs to see if the East/West synchronous city growth hypothesis holds when the units that are compared are somewhat different. Their results confirm the existence of East/West city growth synchrony.

[8] But close inspection of Taagepera’s data reveals that the trajectories and timing of upward sweeps are temporally distinct in different regions.

[9] Robert Carneiro (2004) contends that the current war in Iraq is a sign that global state formation may once again take the road of military conquest. But U.S. unilateralism and the “new imperialism” may also be interpreted as the “imperial overstretch” of a declining hegemon playing one of its last cards. Hardt and Negri (2004) have argued that the largest impediment to the emergence of a United States of the World is the United States of America because the existing U.S. would have to give up some of its power in a global U.S. No longer could the president be elected by a small majority of the citizens of the existing United States.  We see the possibility of the emergence of a global state along the path that has been taken by the European Union, a peaceful and democratic confederation of states on a global scale.

                Recent discourse from global elites at the 2005 World Economic Forum in Davos implies the emergence of a new global Keynesianism that may be replacing the neoliberal “Washington Consensus” as the predominant political ideology of development and global governance. If this is true we may see another round of strengthening of transnational global governance as a method of dealing with the polarization, ecological degradation and increasing conflict that has been generated by the latest wave of globalization.

 

[10] Our conceptualization of political globalization needs to include regional international organizations such as NATO, the Warsaw Pact, COMECON, the European Community, NAFTA, ASEAN, MERCOSUR and etc.
