Multiple states under one central authority, usually created by conquest
An empire is a political unit made up of several territories, military outposts, and peoples, "usually created by conquest, and divided between a dominant center and subordinate peripheries". The center of the empire (sometimes referred to as the metropole) exercises political control over the peripheries. Within an empire, different populations have different sets of rights and are governed differently.
