Third Sacred War: What Happened

The Third Sacred War was fought from 356 to 346 BC over control of the sanctuary of Delphi. It began when the Amphictyonic League, the council responsible for protecting Delphi and dominated by Thebes, imposed a huge fine on the Phocians for farming sacred land. Unable or unwilling to pay, the Phocians, led by Philomelus, seized Delphi itself. To pay for their war, they took the sanctuary's vast treasures of gold and silver offerings and used them to hire large mercenary armies. The conflict drew in much of Greece. After Philomelus died, his successor Onomarchus won notable victories, including against Philip II of Macedon. But in 352 BC, Philip defeated and killed Onomarchus in Thessaly at the Battle of the Crocus Field. The war dragged on until 346 BC, when Philip marched south and forced Phocis to surrender. The Phocian cities were broken up, and Phocis was ordered to repay the stolen treasure. As a reward, Philip took over Phocis's seats on the Amphictyonic Council. The war gave Macedon a powerful voice in the affairs of Greece.
