An allied army led by Philip II of Macedon overcame the forces of city-states led by Athens and Thebes at the Battle of Chaeronea, securing Macedonian hegemony over the majority of ancient Greece. Philip II of Macedon: Philip II of Macedon was the king (basileus) of Macedon from 359 BC until his death in 336 BC. The rise of Macedon, from a kingdom initially at the periphery of classical Greek affairs, to a power that came to dominate Ancient Greece in the span of less than 25 years, was largely thanks to the character and policies of Philip. He was the father of Alexander the Great and a member of the ruling Argead dynasty that founded the kingdom of the Macedonians. August 2, 338 BC. Wiki link
