Adad-nirari III
"The Antakya inscription describes the interference of the Assyrian King in a territorial conflict between Atarsumki, king of Arpad, and Zakkur, king of Hamath ... At that time, both kings were vassals of Adad-nirari III ... the settlement was established in favour of the previously hostile king of Arpad ... The reason for preferring Arpad is clear: it had broken up the lines of the Syro-Hittite coalition, and opened before Adad-nirari III the way to the south, to Damascus."
