History >> Ancient Greece. The Peloponnesian War was fought between the Greek city-states of Athens and Sparta. It lasted from 431 BC to 404 BC. Athens ended up losing the war, bringing an end to the golden age of Ancient Greece.
Wars were very common in ancient Greece. The Greeks lived in little city-states, each one like a small town in the United States today, with no more than about 100,000 people in each city-state. These city-states - Athens, Sparta, Corinth, Thebes - were always fighting each other over their borders. Often they would get together in leagues, a lot of city-states together, to fight as allies. Sometimes other people invaded Greece, and then there would be wars to defend the city-states from the invaders.
