Third Sacred War
The Third Sacred War (356–346 BC) was fought between the forces of the Delphic Amphictyonic League, principally represented by Thebes, and latterly by Philip II of Macedon, and the Phocians. The war was caused by a large fine imposed in 357 BC on the Phocians by the Amphictyonic League (dominated at that moment by Thebes), for the offense of cultivating sacred land; refusing to pay, the Phocians instead seized the Temple of Apollo in Delphi, and used the accumulated treasures to fund large mercenary armies. Thus, although the Phocians suffered several major defeats, they were able to continue the war for many years, until eventually all parties were nearing exhaustion. Philip II used the distraction of the other states to increase his power in northern Greece, in the process becoming ruler of Thessaly. In the end, Philip's growing power, and the exhaustion of the other states, allowed him to impose a peaceful settlement of the war, marking a major step in the rise of Macedon to pre-eminence in Ancient Greece.

On his return to Phocis, Philomelos began assembling a mercenary army using the 15 talents from Archidamos, and also raised a force of 1000 peltasts from amongst the Phocian citizenry. In approximately July 356 BC, Philomelos marched on Delphi, just before the end of the period in which the Phocians had been required to pay their fine. He easily captured the city of Delphi, along with the sanctuary of Apollo. Philomelos captured the nobles of the Thrakidai family, who had probably been involved in imposing the fine on Phocis, and killed them, seizing their wealth to add to his treasury. He promised the other Delphians that he would not harm them, although he had initially contemplated enslaving the whole city.
