State formation is the process of the development of a centralized government structure in a situation where one did not exist prior to its development. State formation has been a study of many disciplines of the social sciences for a number of years, so much so that Jonathan Haas writes that "One of the favorite pastimes of social scientists over the course of the past century has been to theorize about the evolution of the world's great civilizations." The study of state formation is divided generally into the study of early states (those that developed in stateless societies) and modern states (particularly of the form that developed in Europe in the 1600s and spread around the world). A number of different theories explain the development of early states and modern states, and many of the academic debates remain prominent in different fields of study.
The state 
There is no clear consensus on the defining characteristics of a state and the definition can change significantly based upon the context. In general though, for studies of state formation, the state is considered to be a territorially bound political unit with centralized institutions for the administration of governance, as distinct from tribes or units without centralized institutions.
Explaining early states and explaining modern states 
Theories of state formation have two distinct focuses, depending largely on the field of study. One focus of study is on the early transition in human society from tribal communities into larger political organizations. These studies, often in anthropology, explore the initial development of basic administrative structures in areas where states developed from stateless societies. Although state formation was an active research agenda in anthropology and archaeology for a number of years, some of the effort has changed to focus not on why these states formed but on how they operated. In contrast, Political science and Sociology have focused significantly on the formation of the modern state.
Early state formation 
|Area||First State||Approximate Year|
|Indus River Valley||Harappa||2000 B.C.E.|
|North China||Shang Dynasty||1800 B.C.E.|
|Peru||Moche, Tiwanaku, and Wari||400-600 C.E.|
|Mesoamerica||Monte Albán||100 B.C.E.|
Studies of early state formation focus on primary states (of which there may be few) and early states (which formed in different parts of the world throughout history). Primary states are defined as those states that developed in a context with no contact or prior development of a state in the area. These examples are those situations where states developed for the first time in that social environment. The exact number of cases which qualify as primary states is not clearly known because of limited information about political organization before writing in many places; However, the list typically includes the first states to develop in Egypt, Mesopotamia, the Indus river valley, North China, Peru, and Mesoamerica. Similarly, Cohen identifies six zones of independent state development: 1. a connected zone including Europe, North Africa, the Nile river valley, East and South Asia, 2. Mesoamerica, 3. Peru, 4. West Africa, 5. East Africa, and 6. Polynesia.
Early state formation focuses on processes that create and institutionalize a state in a situation where a state did not exist before. Examples of these states that developed in interaction with other states include states like the Aegean Bronze Age Greek civilizations and the Malagasy civilization in Madagascar. Unlike primary state formation, this does not require the creation of the first state in that cultural context or to be developed autonomous from state development nearby. Early state formation causation can thus include borrowing, imposition, and other forms of interaction with already existing states.
Modern state formation 
Modern state formation theories focus on the processes that support the development of modern states, particularly those that formed in late-medieval Europe and then spread around the world with colonialism. Starting in the 1940s and 1950s, with decolonization processes, attention began to focus on the formation and construction of modern states with significant bureaucracies, ability to tax, and territorial sovereignty around the world. However, many scholars hold that the modern state formed in other parts of the world prior to colonialism, but that it was replaced by colonial structures.
Theories about early state development 
There are a number of different theories and hypotheses regarding early state formation that seek generalizations to explain why the state developed in some places but not others. Other scholars believe that generalizations are unhelpful and that each case of early state formation should be treated on its own.
Voluntary theories 
Voluntary theories contend that diverse groups of people came together to form states as a result of some shared rational interest. The theories largely focus on the development of agriculture, and the population and organizational pressure that followed and resulted in state formation. The argument is that such pressures result in integrative pressure for rational people to unify and create a state. Much of the social contract philosophical traditional proposed a voluntary theory for state formation.
One of the most prominent theories of early and primary state formation is the hydraulic hypothesis, which contends that the state was a result of the need to build and maintain large-scale irrigation projects. The theory was most significantly detailed Karl August Wittfogel's argument that, in arid environments, farmers would be confronted by the production limits of small-scale irrigation. Eventually different agricultural producers would join together in response to population pressure and the arid environment, to create a state apparatus that could build and maintain large irrigation projects.
In addition to this, is what Carneiro calls the automatic hypothesis, which contends that the development of agriculture easily produces conditions necessary for the development of a state. With surplus food stocks created by agricultural development, creation of distinct worker classes and a division of labor would automatically trigger creation of the state form.
A third voluntary hypothesis, particularly common with some explanations of early state development, is that long distance trade networks created an impetus for states to develop at key locations: such as ports or oases. For example, the increased trade in the 1500s may have been a key to state formation in West African states such as Whydah, Dahomey, and the Benin Empire.
Conflict theories 
Conflict theories of state formation contend that conflict and dominance of some population over another population is key to the formation of the state. In contrast with voluntary theories, these arguments believe that people do not voluntarily agree to create a state, but that states are created by some form of dominance of some population over another population. There are a number of different theories that rely on conflict, dominance, or oppression as a causal process or a necessary mechanism within certain conditions and they may borrow from other approaches. In general the theories include: Economic stratification, Conquest of other peoples, conflict in Circumscribed areas, and neoevolutionary growth of bureaucracy.
- Economic stratification
- One of the earliest theories based on anthropological evidence was Friedrich Engels' theory of the state in The Origin of the Family, Private Property and the State (1884). The theory of Engels developed from study of Ancient Society by Lewis H. Morgan and the sketches of this work by Karl Marx on the Asiatic mode of production. Engels then argued that the state developed as a result of the need to protect private property. The theory contended that surplus production as a result of the development of agriculture created a division and specialization of labor: creating classes who worked the land and those who could devote time to other tasks. Class antagonism and the need to secure the private property of those living on the surplus production produced by agriculturalists resulted in the creation of the state.
- Conquest theories
- Similar to the economic stratification theories, the conquest theory contends that the state was created by one city to control other tribes or settlements it had conquered. The theory has its roots in the work of Ibn Khaldun (1332-1406) and Jean Bodin (1530–1596), but it was first organized around anthropological evidence by Franz Oppenheimer (1864-1943). Oppenheimer argues that the state was created to cement inequality between peoples that resulted from conquest.
- Carneiro's circumscription theory
- Robert Carneiro created a theory aiming to provide a more nuanced understanding of state formation by accounting for the fact that many factors (surplus agriculture, warfare, irrigation, conquest, etc.) did not produce states in all situations. His answer was that while population pressure and warfare were mechanisms of state formation, they only created states in geographic regions circumscribed, or walled off from the surrounding area. Geographic barriers (or in some cases barriers created by nomadic raiders or rival societies) create limitations on the ability of the people to deal with production shortfalls and the result is that warfare results in state creation. In situations of unlimited agricultural land (like the Amazon or Eastern United States), Carneiro believes that the pressures did not exist and so warfare allowed people to move elsewhere and thus did not spur creation of the state.
- Neoevolutionary theories
- A number of different theories, sometimes connected with some of the processes above, explain state formation in terms of the basic evolution of leadership systems. The basis of the argument is that human society evolved from tribes or chiefdoms into states through a gradual process of transformation that let a small group hierarchically structure society and maintain order through appropriation of symbols of power. Groups that gained power in tribal society gradually worked towards building the hierarchy and segmentation that created the state.
- Elman Service's theory of state formation argues that, unlike in economic stratification theories, the state largely creates stratification in society rather than being created to defend that stratification. Bureaucracy evolves to support the leadership structure in tribes and uses religious hierarchy and economic stratification as means to further increase their power. Warfare may play a key role in the situation, because it allows leaders to distribute benefits in ways that serve their interests, however it is a constant that feeds the system rather than an autonomous factor. Similarly, anthropologist Henry T. Wright argues that competitive and conflictual environments produce political experimentation leading to the development of the state. As opposed to theories that the state develops through chance or tinkering, experimentation involves a more directed process where tribal leaders learn from organization forms of the past and the outcomes they produced.
Other theories 
Other aspects are highlighted in different theories as of contributing importance. It is sometimes claimed that technological development, religious development, or socialization of members are crucial to state development. However, most of these factors are found to be secondary in anthropological analysis. In addition to conquest, some theories contend that the need for defense from military conquest or the military organization to conquer other peoples is the key aspect leading to state formation.
Discredited theories 
Some theories proposed in the 1800s and early 1900s have since been largely discredited by anthropologists. These include theories that early state formation resulted from racial superiority, historical accident, or from a shared consciousness of the people. Similarly, Social Darwinism perspectives—prominent in the work of Walter Bagehot— maintained that the state form developed as a result of the best leaders and organized societies gradually gaining power until the state formed. These are not considered sufficient causes in recent scholarship.
Theories about modern state development 
In the medieval period (500 C.E.-1400 C.E.) in Europe, there were a variety of authority forms throughout the region. These included feudal lords, empires, religious authorities, free cities, and other authorities. Often dated to the 1648 Peace of Westphalia, there began to be the development in Europe of modern states with large-scale capacity for taxation, coercive control of their populations, and advanced bureaucracies. The state became prominent in Europe over the next few centuries before the particular form of the state spread to the rest of the world via the colonial and international pressures of the 1800s and 1900s. Other modern states developed in Africa and Asia prior to colonialism, but were largely displaced by colonial rule.
Political scientists, sociologists, and anthropologists began studying the state formation processes in Europe and elsewhere in the 1600s—beginning significantly with Max Weber. However, state formation became a primary interest in the 1970s. The question was often framed as a contest between state forces and society forces and the study of how the state became prominent over particular societies. A number of theories developed regarding state development in Europe. Other theories focused on the creation of states in late colonial and post-colonial societies. The lessons from these studies of the formation of states in the modern period are often used in theories about State-building. Other theories contend that the state in Europe was constructed in connection with peoples from outside Europe and that focusing on state formation in Europe as a foundation for study silences the diverse history of state formation.
Warfare theories 
Two related theories are based on military development and warfare, and the role that these forces played in state formation. Charles Tilly developed an argument that the state developed largely as a result of "state-makers" who sought to increase the taxes they could gain from the people under their control so they could continue fighting wars. In the constant warfare of the centuries in Europe, coupled with expanded costs of war with mass armies and gunpowder, warlords had to find ways to finance war and control territory more effectively. The modern state presented the opportunity for them to develop taxation structures, the coercive structure to implement that taxation, and finally the guarantee of protection from other states that could get much of the population to agree.
Michael Roberts and Geoffrey Parker, in contrast, finds that the primary causal factor was not the "state-makers" themselves, but simply the military revolutions that allowed development of larger armies. The argument is that with the expanded state of warfare, the state became the only administrative unit that could endure in the constant warfare in the Europe of this period, because only it could develop large enough armies. This view—that the modern state replaced chaos and general violence with internal disciplinary structures—has been challenged as ethnocentric, and ignoring the violence of modern states.
Feudal crisis theories 
Another argument contends that the state developed out of economic and social crises that were prominent in late-medieval Europe. Religious wars between Catholics and Protestants, and the involvement of leaders in the domains of other leaders under religious reasons was the primary problem dealt with in the Peace of Westphalia. In addition, Marxist theory contends that the economic crisis of feudalism forced the aristocracy to adopt their forms of organization so they could retain economic power, and this resulted in the formation of the modern state.
Cultural theories 
Some scholarship, linked to wider debates in Anthropology, has increasingly emphasized the state as a primarily cultural artifact, and focuses on how symbolism plays a primary role in state formation. Most explicitly, some studies emphasize how the creation of national identification and citizenship were crucial to state formation. The state then is not simply a military or economic authority, but also includes cultural components creating consent by people by giving them rights and shared belonging.
Outside Europe 
Modern states were created without European influence in some parts of Africa, Latin America, and elsewhere before colonialism. However, much of attention has focused on how states developed in Africa in the situation of post-colonial state formation. Although warfare is primary in many theories of state formation in Europe, with the development of the international norm of non-interventionism this process of state formation has decreased in relevance and other processes of state formation have become prominent outside Europe (including colonial imposition, assimilation, borrowing, and some internal political processes).
One explicit theory of the expansion of the state formation outside Europe is John W. Meyer's World Society Theory, which contends that the state form was part of a diffusion from Europe, institutionalized in the United Nations, and gradually the nation-state became the basis for both those in power and those challenging power. In addition, since the first modern states (the United Kingdom, United States, and France) took over significant empires in much of the rest of the world, it is sometimes argued that they set the institutional starts and that future developments were either imposed or copied from them because they were seen as successful.
