What did the Greek polis began as what?

The Greek polis began as a small community or settlement that evolved from agricultural villages. These early settlements were centered around a fortified hilltop, known as the acropolis, and a surrounding area called the agora, which served as a public space for gatherings and commerce. Over time, as populations grew and social structures became more complex, these settlements developed into city-states with their own governments, cultures, and identities, becoming the foundation of classical Greek civilization.
