The State is a political unit with the power to make laws and enforce them by a group living within an expressly determined territory. Therefore, it is a territorially delimited sovereign system of government governed on behalf of a community of citizens who identify as a nation.
The legitimacy of the government of a State over a territory and over the population that inhabits it derives from the right to self-determination of a national group within the State.
The national group members consider that the State belongs to them and that the territory of the State is their homeland. Consequently, they demand that other groups, inside and outside the State, recognize and respect their control over it.
