Polis, plural poleis, literally means city in Greek. It can also mean a body of citizens. In modern historiography, polis is normally used to indicate the ancient Greek city-states, like Classical Athens and its contemporaries, and thus is often translated as city-state. These cities consisted of a fortified city centre built on an acropolis or harbor and controlled surrounding territories of land. The Ancient Greek city-state developed during the Archaic period as the ancestor of city, state, and citizenship and persisted (though with decreasing influence) well into Roman times, when the equivalent Latin word was civitas, also meaning citizenhood, while municipium applied to a non-sovereign local entity.
