Under Philip’s rule, Macedon transformed from a poor backwater to the most powerful state in the Greek world, setting the stage for his son, Alexander The Great conquests. In 356 BC, Philip won control of Thessaly, and the victory of his race horse in the Olympic games earned him more prestige. A blunt, hard-drinking, and uncultured man, Philip was beloved by his soldiers and detested by the elite of most Greek cities, particularly Athens. In 338 BC he crushed a combined Athenian-Theban army at Chaeronea, making him effective master of all Greece. His ultimate aim was to lead a united Greek army against the Persian Empire, but his assassination in 336 BC left the task to his charismatic son. His coinage in gold and silver was immense and coins continued to be minted with his name and types long after his death.
