When we think of state power over territory, we think precisely of what defines the state as the state. In sociologist Max Weber's classic definition, the state is that set of institutions which enjoys "the monopoly of the legitimate use of physical force within a given territory." This power is coercive: the state, by virtue of its control over the police, law, military, etc., has the power to coerce you, if you are inside its territory, to do or not do certain things, and to punish you if you don't follow the rules, which the state itself determines. Virtually all capitalist states limit these powers via laws, constitutions and "bills of rights," for example requiring the police to have a warrant to enter and search your home. But the state (at least in theory) remains the sole possessor of this territorially defined coercive power.
