How Greece Became a Land of City-States (Polis)

No single person divided Greece into city-states. The polis system emerged organically over centuries:

1. 8th Century BCE: Population growth spurred new settlements, often on defensible hilltops (acropoleis).
2. Growing Independence: These settlements gained autonomy from older mother-cities.
3. 6th Century BCE: Hundreds of independent poleis existed, each with its own government, laws, calendar, and identity.

Geography—mountains, islands, isolated valleys—reinforced fragmentation. Famous poleis included Athens, Sparta, Corinth, Thebes, and Miletus.
