357 BC

Events

The Athenian general and mercenary commander, Chares and the Euboean mercenary Charidemus regain the Thracian Chersonese for Athens from the Thracian king Cersobleptes. Charidemus receives from Athens a golden crown for his part in the victory.

The Macedonian general, Parmenio, wins a great victory over the Illyrians. King Philip II of Macedon, having disposed of an Illyrian threat, occupies the Athenian city of Amphipolis (which commands the gold mines of Mount Pangaion). Philip II now has control of the strategic city which secures the eastern frontier of Macedonia and gives him access into Thrace.
Philip II of Macedon marries Olympias, the Molossian princess of Epirus thus helping to stabilize Macedonia's western frontier.

The brother-in-law of Dionysius I, Dion, exiled from Syracuse in 366 BC by Dionysius II, assembles a force of 1,500 mercenaries at Zacynthus and sails to Sicily. Dion wrests power from the weak Dionysius II, who is exiled and flees to Locri.
