The Battle of Qarqar was fought in 853 BC when the army of the Neo-Assyrian Empire led by Emperor Shalmaneser III encountered an allied army of eleven kings at Qarqar led by Hadadezer, called in Assyrian Adad-idir and possibly to be identified with King Benhadad II of Aram-Damascus; and Ahab, king of Israel. This battle, fought during the 854–846 BC Assyrian conquest of Aram, is notable for having a larger number of combatants than any previous battle, and for being the first instance in which some peoples enter recorded history, such as the Arabs. The battle is recorded on the Kurkh Monoliths. Using a different rescension of the Assyrian Eponym List would put the battle's date at 854 BC.

The Neo-Assyrian Empire was the fourth and penultimate stage of ancient Assyrian history. Beginning with the accession of Adad-nirari II in 911 BC, the Neo-Assyrian Empire grew to dominate the ancient Near East throughout much of the 8th and 7th centuries BC, becoming the largest empire in history up to that point. Because of its geopolitical dominance and ideology based in world domination, the Neo-Assyrian Empire is by many researchers regarded to have been the first world empire in history. It influenced other empires of the ancient world culturally, administratively, and militarily, including the Babylonians, the Achaemenids, and the Seleucids. At its height, the empire was the strongest military power in the world and ruled over all of Mesopotamia, the Levant and Egypt, as well as parts of Anatolia, Arabia and modern-day Iran and Armenia.
