Tiglath-Pileser III
In the 8th century BC, Rezin had been a tributary of Tiglath-Pileser III, the king of Assyria. In c. 732 BC, he formed an alliance with Pekah, the king of Israel, to attack Ahaz, the king of Judah. Ahaz appealed to Tiglath-Pileser III for help. This the Assyrian king obliged after Judah paid tribute to the Assyrian king. Tiglath-Pileser III attacked Damascus and annexed Aram. The population was deported and Rezin was executed. Tiglath-Pileser recorded this act in one of his inscriptions.
