Battle of Chaeronea (338 BC)
The Battle of Chaeronea was fought in 338 BC, near the city of Chaeronea in Boeotia, between Macedonia under Philip II and an alliance of city-states led by Athens and Thebes. The battle was the culmination of Philip's final campaigns in 339–338 BC and resulted in a decisive victory for the Macedonians and their allies. Philip had brought peace to a war-torn Greece in 346 BC, by ending the Third Sacred War, and concluding his ten-year conflict with Athens for supremacy in the north Aegean, by making a separate peace. Philip's much expanded kingdom, powerful army and plentiful resources now made him the de facto leader of Greece. To many of the fiercely independent city-states, Philip's power after 346 BC was perceived as a threat, especially in Athens, where the politician Demosthenes led efforts to break away from Philip's influence.
