A sovereign state is a nonphysical juridical entity of the international legal system that is represented by a centralized government that has supreme independent authority over a geographic area. International law defines sovereign states as having a permanent population, a government, and the capacity to enter into relations with other sovereign states. It is also normally understood to be a state which is neither dependent on nor subject to any other power or state. The existence or disappearance of a state is a question of fact. While according to the declarative theory of state recognition a sovereign state can exist without being recognised by other sovereign states, unrecognised states will often find it hard to exercise full treaty-making powers and engage in diplomatic relations with other sovereign states.
Emergence of states
The first states came into existence as people "gradually transferred their allegiance from an individual sovereign (king, duke, prince) to an intangible but territorial political entity, of the state". States are but one of several political orders that emerged from feudal Europe (others being city states, leagues, and empires with universalist claims to authority.
Westphalian sovereignty is the concept of nation-state sovereignty based on territoriality and the absence of a role for external agents in domestic structures. It is an international system of states, multinational corporations, and organizations that began with the Peace of Westphalia in 1648.
Sovereignty is a term that is frequently misused. Up until the 19th century, the radicalised concept of a "standard of civilisation" was routinely deployed to determine that certain peoples in the world were "uncivilised", and lacking organised societies. That position was reflected and constituted in the notion that their "sovereignty" was either completely lacking, or at least of an inferior character when compared to that of "civilised" people." Lassa Oppenheim said "There exists perhaps no conception the meaning of which is more controversial than that of sovereignty. It is an indisputable fact that this conception, from the moment when it was introduced into political science until the present day, has never had a meaning which was universally agreed upon." In the opinion of H. V. Evatt of the High Court of Australia "sovereignty is neither a question of fact, nor a question of law, but a question that does not arise at all."
Sovereignty has taken on a different meaning with the development of the principle of self-determination and the prohibition against the threat or use of force as jus cogens norms of modern international law. The United Nations Charter, the Draft Declaration on Rights and Duties of States, and the charters of regional international organisations express the view that all states are juridically equal and enjoy the same rights and duties based upon the mere fact of their existence as persons under international law. The right of nations to determine their own political status and exercise permanent sovereignty within the limits of their territorial jurisdictions is widely recognised.
In political science, sovereignty is usually defined as the most essential attribute of the state in the form of its complete self-sufficiency in the frames of a certain territory, that is its supremacy in the domestic policy and independence in the foreign one.
- Nation denotes a people who are believed to or deemed to share common customs, religion, language, origins, ancestry or history. However, the adjectives national and international are frequently used to refer to matters pertaining to what are strictly sovereign states, as in national capital, international law.
- State refers to the set of governing and supportive institutions that have sovereignty over a definite territory and population. Sovereign states are legal persons.
State recognition signifies the decision of a sovereign state to treat another entity as also being a sovereign state. Recognition can be either express or implied and is usually retroactive in its effects. It doesn't necessarily signify a desire to establish or maintain diplomatic relations.
There is no definition that is binding on all the members of the community of nations on the criteria for statehood. In actual practice, the criteria are mainly political, not legal. L.C. Green cited the recognition of the unborn Polish and Czech states in World War I and explained that "since recognition of statehood is a matter of discretion, it is open to any existing State to accept as a state any entity it wishes, regardless of the existence of territory or of an established government."
In international law, however, there are several theories of when a state should be recognized as sovereign.
The constitutive theory of statehood defines a state as a person of international law if, and only if, it is recognized as sovereign by other states. This theory of recognition was developed in the 19th century. Under it, a state was sovereign if another sovereign state recognized it as such. Because of this, new states could not immediately become part of the international community or be bound by international law, and recognized nations did not have to respect international law in their dealings with them. In 1815 at the Congress of Vienna the Final Act recognised only 39 sovereign states in the European diplomatic system, and as a result it was firmly established that in future new states would have to be recognized by other states, and that meant in practice recognition by one or more of the great powers.
One of the major criticisms of this law is the confusion caused when some states recognize a new entity, but other states do not. Hersch Lauterpacht, one of the theory's main proponents, suggested that it is a state's duty to grant recognition as a possible solution. However, a state may use any criteria when judging if they should give recognition and they have no obligation to use such criteria. Many states may only recognize another state if it is to their advantage.
In 1912, L. F. L. Oppenheim had the following to say on constitutive theory:
...International Law does not say that a State is not in existence as long as it isn't recognised, but it takes no notice of it before its recognition. Through recognition only and exclusively a State becomes an International Person and a subject of International Law.
By contrast, the "declarative" theory defines a state as a person in international law if it meets the following criteria: 1) a defined territory; 2) a permanent population; 3) a government and 4) a capacity to enter into relations with other states. According to declarative theory, an entity's statehood is independent of its recognition by other states. The declarative model was most famously expressed in the 1933 Montevideo Convention.
Article 3 of the Montevideo Convention declares that statehood is independent of recognition by other states. In contrast, recognition is considered a requirement for statehood by the constitutive theory of statehood.
A similar opinion about "the conditions on which an entity constitutes a state" is expressed by the European Economic Community Opinions of the Badinter Arbitration Committee, which found that a state was defined by having a territory, a population, and a political authority.
State practice relating the recognition states typically falls somewhere between the declaratory and constitutive approaches. International law does not require a state to recognise other states.
Recognition is often withheld when a new state is seen as illegitimate or has come about in breach of international law. Almost universal non-recognition by the international community of Rhodesia and Northern Cyprus are good examples of this. In the former case, recognition was widely withheld when the white minority seized power and attempted to form a state along the lines of Apartheid South Africa, a move that the United Nations Security Council described as the creation of an "illegal racist minority régime". In the latter case, recognition was widely withheld from a state created in Northern Cyprus on land illegally invaded by Turkey in 1974.
De facto and de jure states
Most sovereign states are states de jure and de facto (i.e. they exist both in law and in reality). However, sometimes states exist only as de jure states in that an organisation is recognised as having sovereignty over and being the legitimate government of a territory over which they have no actual control. Many continental European states maintained governments-in-exile during the Second World War which continued to enjoy diplomatic relations with the Allies, notwithstanding that their countries were under Nazi occupation. The State of Palestine, which is recognized by most states doesn't have control over any of its claimed territory in Palestine and possess only extraterritorial areas (i.e. embassies and consulates). Other states may have sovereignty over a territory but lack international recognition; these are considered by the international community to be only de facto states (they are considered de jure states only according to their own Law and by states that recognize them). Somaliland is commonly considered to be such a state. For a list of entities that wish to be universally recognized as sovereign states, but do not have complete worldwide diplomatic recognition, see the list of states with limited recognition.
