Definition
There is no academic consensus on the definition of the state. The term "state" refers to a set of different, but interrelated and often overlapping, theories about a certain range of political phenomena. According to Walter Scheidel, mainstream definitions of the state have the following in common: "centralized institutions that impose rules, and back them up by force, over a territorially circumscribed population; a distinction between the rulers and the ruled; and an element of autonomy, stability, and differentiation. These distinguish the state from less stable forms of organization, such as the exercise of chiefly power."
The most commonly used definition is by Max Weber who describes the state as a compulsory political organization with a centralized government that maintains a monopoly of the legitimate use of force within a certain territory. Weber writes that the state "is a human community that (successfully) claims the monopoly of the legitimate use of physical force within a given territory."
While defining a state, it is important not to confuse it with a nation; an error that occurs frequently in common discussion. A state refers to a political unit with sovereignty over a given territory. While a state is more of a "political-legal abstraction," the definition of a nation is more concerned with political identity and cultural or historical factors. Importantly, nations do not possess the organizational characteristics like geographic boundaries or authority figures and officials that states do. Additionally, a nation does not have a claim to a monopoly on the legitimate use of force over their populace, while a state does, as Weber indicated. An example of the instability that arises when a state does not have a monopoly on the use of force can be seen in African states which remain weak due to the lack of war which European states relied on. A state should not be confused with a government; a government is an organization that has been granted the authority to act on the behalf of a state. Nor should a state be confused with a society; a society refers to all organized groups, movements, and individuals who are independent of the state and seek to remain out of its influence.
Neuberger offers a slightly different definition of the state with respect to the nation: the state is "a primordial, essential, and permanent expression of the genius of a specific [nation]."
The definition of a state is also dependent on how and why it forms. The contractarian view of the state suggests that states form because people can all benefit from cooperation with others and that without a state, there would be chaos. The contractarian view focuses more on the alignment and conflict of interests between individuals in a state. On the other hand, the predatory view of the state focuses on the potential mismatch between the interests of the people and the interests of the state. Charles Tilly goes so far as to say that states "resemble a form of organized crime and should be viewed as extortion rackets." He argued that the state sells protection from itself and raises the question about why people should trust a state when they cannot trust one another.
Tilly defines states as "coercion-wielding organisations that are distinct from households and kinship groups and exercise a clear priority in some respects over all other organizations within substantial territories." Tilly includes city-states, theocracies and empires in his definition along with nation-states, but excludes tribes, lineages, firms and churches. According to Tilly, states can be seen in the archaeological record as of 6000 BC; in Europe, they appeared around 990, but became particularly prominent after 1490. Tilly defines a state's "essential minimal activities" as:
War making – "eliminating or neutralizing their outside rivals"
State making – "eliminating or neutralizing their rivals inside their own territory"
Protection – "eliminating or neutralizing the enemies of their clients"
Extraction – "acquiring the means of carrying out the first three activities"
Adjudication – "authoritative settlement of disputes among members of the population"
Distribution – "intervention in the allocation of goods among the members of the population"
Production – "control of the creation and transformation of goods and services produced by the population"
Importantly, Tilly makes the case that war is an essential part of state-making; that wars create states and vice versa.
Modern academic definitions of the state frequently include the criterion that a state has to be recognized as such by the international community.
Liberal thought provides another possible teleology of the state. According to John Locke, the goal of the state or commonwealth is "the preservation of property" (Second Treatise on Government), with 'property' in Locke's work referring not only to personal possessions but also to one's life and liberty. On this account, the state provides the basis for social cohesion and productivity, creating incentives for wealth-creation by providing guarantees of protection for one's life, liberty, and personal property. Provision of public goods is considered by some such as Adam Smith as a central function of the state, since these goods would otherwise be underprovided. Tilly has challenged narratives of the state as being the result of a societal contract or provision of services in a free market – he characterizes the state more akin to a protection racket in the vein of organized crime.
While economic and political philosophers have contested the monopolistic tendency of states, Robert Nozick argues that the use of force naturally tends towards monopoly.
Another commonly accepted definition of the state is the one given at the Montevideo Convention on the Rights and Duties of States in 1933. It provides that "[t]he state as a person of international law should possess the following qualifications: (a) a permanent population; (b) a defined territory; (c) government; and (d) capacity to enter into relations with the other states." And that "[t]he federal state shall constitute a sole person in the eyes of international law."
Confounding the definition problem is that "state" and "government" are often used as synonyms in common conversation and even some academic discourse. According to this definition schema, the states are nonphysical persons of international law, and governments are organizations of people. The relationship between a government and its state is one of representation and authorized agency.
