From the Polis to Alexander's World-Empire

The classical Greek polis — Athens, Sparta, Thebes, and hundreds of smaller city-states — was conceived as a self-governing community of citizens (politai) bound together by shared law (nomos) and direct participation in public life. In the opening book of his Politics (1253a), Aristotle treats the polis as prior to the individual by nature, the necessary context in which human flourishing (eudaimonia) could be realized at all. Citizenship (politeia) was a jealously guarded status, typically restricted to free adult males born of citizen parents and excluding women, slaves, and resident foreigners (metics) from formal political life. Civic virtue (arete) was accordingly understood in practical terms, exercised in the assembly, the law courts, and military service, rather than as an abstract inner disposition. Plato's Republic and Laws likewise treat the just city as the indispensable framework for the just soul, tightly linking individual psychology to political structure. This close identification of ethics with citizenship gave classical Greek philosophy its distinctive horizon: to ask how one should live well was, in practice, to ask how one should live well as a citizen of a particular polis.
