Sarduri II
In the reign of Tarhulara in 743 BC, Gurgum also took part in an anti-Assyrian military alliance led by Sarduri II of Urartu and Mati-Ilu of Arpad. The Assyrian king Tiglath-pileser III defeated the hostile alliance and also invaded Gurgum, destroying 100 Gurgumaean cities. Tarhulara submitted and beseeched the Assyrian king to spare the capital Marqas. Tarhulara was allowed to stay on the throne and henceforth was an Assyrian tributary, paying tribute to the Assyrian king in 738 and 732 BC.
