National political systems
The term nation-state is used so commonly and yet defined so variously that it will be necessary to indicate its usage in this article with some precision and to give historical and contemporary examples of nation-states. To begin with, there is no single basis upon which such systems are established. Many states were formed at a point in time when a people sharing a common history, culture, and language discovered a sense of identity. This was true in the cases of England and France, for example, which were the first nation-states to emerge in the modern period, and of Italy and Germany, which were established as nation-states in the 19th century. In contrast, however, other states, such as India, the Soviet Union, and Switzerland, came into existence without a common basis in ethnicity, culture, or language. It must also be emphasized that contemporary nation-states are creations of different historical periods and of varied circumstances. Before the close of the 19th century, the effective mobilization of governmental powers on a national basis had occurred only in Europe, the United States, and Japan. It was not until the 20th century and the collapse of the Ottoman, Habsburg, French, and British empires that the bulk of the world could be organized on a national basis. This transformation continued with the dissolution of the Soviet Union, which ceased to exist in 1991, and Yugoslavia, which finally disappeared from the map in 2003. In 1920 the League of Nations had recognized seven nation-states as “Great Powers”—the United Kingdom, France, the United States, Germany, Italy, Japan, and Russia—and it eventually admitted more than 40 other states to membership. Its successor, the United Nations, had more than 190 member states in the early 21st century. States in the post-Cold War world include the Great Powers, which, along with Canada, now constitute the highly industrialized countries known as the Group of Eight (G8); numerous other populous and prominent countries, such as Argentina, Australia, Brazil, China, Egypt, Greece, Hungary, India, Indonesia, Iran, Ireland, Kenya, Mexico, Nigeria, Pakistan, Poland, Saudi Arabia, South Africa, South Korea, Spain, Sweden, Switzerland, Turkey, and Venezuela; and a host of other states, from the tiny Pacific island country of Nauru to the vast Central Asian country of Kazakhstan.
The characteristics that qualify these variously composed and historically differing entities as nation-states and distinguish them from other forms of social and political organization amount in sum to the independent power to compel obedience from the populations within their territories. The state is, in other words, a territorial association that may range in size from Russia to Singapore, in population from China to Luxembourg, and that claims supremacy over all other associations within its boundaries. As an association, the state is peculiar in several respects: membership is compulsory for its citizens; it claims a monopoly of the use of armed force within its borders; and its officers, who are the government of the state, claim the right to act in the name of the land and its people.
A definition of the state in terms only of its powers over its members is not wholly satisfactory, however. Although all states make a claim to supremacy within their boundaries, they differ widely in their ability to make good their claims. States are, in fact, often challenged by competing associations within their boundaries; their supremacy is often more formal than real; and they are sometimes unable to maintain their existence. Moreover, a definition in terms of power alone ignores the fact that there are great differences among states in the structures they employ for the exercise of power, in the ways they use power, and in the ends to which they turn their power. Some of these differences are explored in the discussion that follows of two general categories of nation-states: the unitary state and the federal state. Partly from administrative necessity and partly because of the pressures of territorial interests, nearly all modern states provide for some distribution of governmental authority on a territorial basis. Systems in which power is delegated from the central government to subnational units and in which the grant of power may be rescinded at the will of the central government are termed unitary systems. Systems in which a balance is established between two autonomous sets of governments, one national and the other provincial, are termed federal. In federal systems, the provincial units are usually empowered to grant and take away the authority of their own subunits in the same manner as national governments in unitary systems. Thus, although the United States is federally organized at the national level, each of the 50 states is in a unitary relationship to the cities and local governments within its own territory.
Unitary nation-states
A great majority of all the world’s nation-states are unitary systems, including Bulgaria, France, Great Britain, the Netherlands, Japan, Poland, Romania, the Scandinavian countries, Spain, and many of the Latin American and African countries. There are great differences among these unitary states, however, specifically in the institutions and procedures through which their central governments interact with their territorial subunits.
In one type of unitary system, decentralization of power among subnational governments goes so far that in practice, although not in constitutional principle, they resemble federal arrangements. In Great Britain, for example, there are important elements of regional autonomy in the relationship between Northern Ireland, Wales, and Scotland and the national government in London; and the complex system of elected local governments, although in constitutional theory subject to abrogation by Parliament, is in practice a fixed and fairly formidable part of the apparatus of British government. In other unitary systems of this type, decentralization on a territorial basis is actually provided for constitutionally, and the powers of locally elected officials are prescribed in detail. Thus, the Japanese constitution, for example, specifies certain autonomous functions to be performed by local administrative authorities.
A second type of unitary system makes less provision for territorial decentralization of authority and employs rather strict procedures for the central supervision of locally elected governments. The classic example of this type is pre-1982 France. Until March 1982, when a law on decentralization went into effect, the French administrative system was built around départements, each headed by a préfet, and subdivisions of the départements, termed arrondissements, each headed by a sous-préfet. The préfets and sous-préfets were appointed by the government in Paris to serve as agents of the central government and also as the executives of the divisional governments, the conseils généraux, which were composed of elected officials. The system thus combined central supervision of local affairs through appointed officials with territorial representation through locally elected governments. (Following the passage of the decentralization law, the executive powers of the préfets were transferred to the elected conseils généraux; moreover, many functions previously performed by the central government were devolved to the newly created régions, units of local government that each encompassed a number of départements and that were overseen by directly elected regional councils.)
Yet a third type of unitary system provides for only token decentralization. In such cases, the officials responsible for managing the affairs of the territorial subdivisions are appointees of the central government, and the role of locally elected officers is either minimal or nonexistent. Examples of this kind of arrangement include Germany under Adolf Hitler and also several formerly communist countries. The Third Reich was divided into 42 Gaue, each headed by a gauleiter chosen for his personal loyalty to Hitler. In eastern Europe, the people’s councils or people’s committees were named by the centrally organized communist parties; their appointment was confirmed by elections with one slate of candidates.
