Philip II of Macedon Wins the Battle of Chaeronea
On August 2, 338 BC, Macedonian king Philip II defeated the combined forces of Athens and Thebes at the Battle of Chaeronea in Boeotia, Greece. The victory gave Philip effective control over most of mainland Greece and paved the way for a unified Hellenic league under his leadership. His son Alexander, later called “the Great,” reportedly commanded the Macedonian left wing, gaining his first major taste of battle. The outcome reshaped Greek politics and cleared the stage for Alexander’s later campaigns across Persia and beyond.
