Battle of Kadesh, (1275 BC), major battle between the Egyptians under Ramses II and the Hittites under Muwatallis, in Syria, southwest of Ḥimṣ, on the Orontes River. In one of the world’s largest chariot battles, fought beside the Orontes River, Pharaoh Ramses II sought to wrest Syria from the Hittites and recapture the Hittite-held city of Kadesh. There was a day of carnage as some 5,000 chariots charged into the fray, but no outright victor. The battle led to the world’s first recorded peace treaty.
