The Battle of Chaeronea took place in 338 BCE between the forces of the Kingdom of Macedon, led by Philip II, and a coalition of Greek city-states, including Athens and Thebes. This battle was significant as it marked the rise of Macedon as a dominant power in Greece, showcasing the effectiveness of the Macedonian phalanx and cavalry tactics. The Macedonian victory at Chaeronea led to the establishment of the Corinthian League, which united the Greek states under Macedonian hegemony. This battle also set the stage for the future conquests of Philip's son, Alexander the Great, who would go on to expand Macedonian influence across much of the known world.
