The Battle of Chaeronea: Philip II’s Greatest Victory
Introduction
The Battle of Chaeronea was a decisive confrontation that marked the end of independent Greek city-state dominance. Fought in 338 BCE, it was the greatest victory of Philip II of Macedon, who established Macedonian supremacy over Greece.
Background of the Conflict
By the 4th century BCE, Greek city-states were weakened by constant warfare, especially after the Peloponnesian War.
Key Developments:
