Why did the pelapanesian war happen?

Answer 1

The Peloponnesian War occurred primarily due to rising tensions between the Athenian Empire and the Peloponnesian League, led by Sparta. Athens' expanding influence and imperial ambitions threatened the autonomy of other city-states, leading to fears and rivalries. Key events, such as the conflict over Corcyra and the siege of Potidaea, escalated the situation, ultimately resulting in a full-scale war that lasted from 431 to 404 BCE. The war had profound effects on ancient Greece, leading to the decline of Athenian power and the eventual rise of Sparta.
