Chaeronea(redirected from Cheronia)
Also found in: Dictionary, Thesaurus.
an ancient city in Boeotia, Greece. The battle of Chaeronea took place not far from the city on Aug. 2 or, according to some sources, Sept. 1, 338 B.C. In the battle, an army 30,000 strong under Philip II of Macedon clashed with forces of roughly equal strength sent by Athens and Boeotia. The joint action of the Macedonian cavalry and the left wing of the Macedonian phalanx decided the battle for Philip. The left wing, which was under the command of the king’s 18-year-old son Alexander (the Great), attacked while the cavalry outflanked the enemy’s right. Philip’s victory led to the establishment of Macedonian hegemony in Greece.
