Sarduri II
Arpad later became a major vassal city of the Kingdom of Urartu. In 743 BC, during the Urartu-Assyria War, the Neo-Assyrian king Tiglath-Pileser III laid siege to Arpad following the defeat of the Urartian army of Sarduri II at Samsat. But the city of Arpad did not surrender easily. It took Tiglath-Pileser three years of siege to conquer Arpad, whereupon he massacred its inhabitants and destroyed the city. Afterward Arpad served a provincial capital. The remains of Arpad's walls are still preserved in Tell Rifaat to the height of 8 meters. A coalition of princes which had been allied to the city was also defeated, including the kings of Kummuh, Quwê, Carchemish and Gurgum. Bit Agusi was never repopulated.
