Characteristics of the city in a polis were outer walls for protection, as well as a public space that included temples and government buildings. The temples and government buildings were often built on the top of a hill, or acropolis. A surviving example of a structure central to an ancient acropolis is the famous Parthenon of Athens. The Parthenon was a temple built to honor the goddess Athena. The majority of a polis’s population lived in the city, as it was the center of trade, commerce, culture, and political activity.
There grew to be over 1,000 city-states in ancient Greece, but the main poleis were Athína (Athens), Spárti (Sparta), Kórinthos (Corinth), Thíva (Thebes), Siracusa (Syracuse), Égina (Aegina), Ródos (Rhodes), Árgos, Erétria, and Elis.

It emphasized maintaining a strong military, while Athens valued education and art. In Athens every male citizen had the right to vote, so they were ruled by a democracy. Rather than have a strong army, Athens maintained their navy.
Greek city-states likely developed because of the physical geography of the Mediterranean region. The landscape features rocky, mountainous land and many islands. These physical barriers caused population centers to be relatively isolated from each other. The sea was often the easiest way to move from place to place. Another reason city-states formed, rather than a central, all-encompassing monarchy, was that the Greek aristocracy strove to maintain their city-states’ independence and to unseat any potential tyra
