[1] Sargon led multiple offensives deep into Urartian territory, amassing numerous victories in the war.
However, the Assyrian King Tiglath-Pileser III saw the rising Kingdom of Urartu as a growing threat to the safety of his empire.
After Sargon's death in 706 BC, King Rusa's successor, Argishti II, launched a major counterattack, with his forces driving the Assyrians back across the pre-war border and deep into Assyrian colonies in northwestern Iran, reconquering major towns and cities around Lake Urmia, including Mushashir, Ushnu, and Tepe.
After the Uratuan victories during the early part of King Argishti II's reign, Urartu experienced a "Golden Age" characterized by a lengthy peace and economic prosperity throughout the remainder of Arghisti's reign and the entire rule of his successor, Rusa II.
This ultimately turned Urartu into an Assyrian client state, used as a buffer on the northern borders of this powerful empire.
