What is Sovereign State?

Alternative Forms: Sovereign states
Legal Definition
A sovereign state is, in international law, a nonphysical juridical entity that is represented by one centralised government that has sovereignty over a geographic area. International law defines sovereign states as having a permanent population, defined territory, one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is neither dependent on nor subjected 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 statehood, 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.

Legal Definition
States whose subjects or citizens are in the habit of obedience to them, and which are not themselves subject to any other (or paramount) state in any respect. The state is said to be semisovereign only, and not sovereign, when in any respect or respects it is liable to be controlled (like certain of the states in India) by a paramount government, (e. g., by the British empire.) Brown. "In the intercourse of nations, certain states have a position of entire independence of others, and can perform all those acts which it is possible for any state to perform in this particular sphere. These same states have also entire power of self-government; that is, of independence upon all other states as far as their own territory and citizens not living abroad are concerned. No foreign power or law can have control except by convention. This power of independent action in external and internal relations constitutes complete sovereignty." Wools. Pol. Science, I. 204.
