Siege of Potidaea: What Happened

The Siege of Potidaea, from 432 to 430 BC, was one of the key events that led to the Peloponnesian War. Potidaea was a city on the Chalkidiki peninsula in northern Greece. It paid tribute to Athens as a member of the Delian League, but it had been founded by Corinth and still kept close ties with its mother city. When Athens, fearing a revolt, ordered Potidaea to tear down part of its walls and send away its Corinthian magistrates, the city rebelled with support from Corinth. Athens sent an army that defeated a Corinthian force outside the city and then surrounded Potidaea with siege walls. Among the Athenian soldiers were the philosopher Socrates and the young Alcibiades, and Socrates is said to have saved Alcibiades' life in battle. The siege dragged on for more than two years and cost Athens a fortune, as the defenders were starved into eating their own dead. Potidaea surrendered in the winter of 430 to 429 BC. Corinth's anger over the siege helped push Sparta into war with Athens.
