Sargon II (Neo-Assyrian Akkadian: 𒈗𒁺, romanized: Šarru-kīn, meaning "the faithful king" or "the legitimate king") was the king of the Neo-Assyrian Empire from 722 BC to his death in battle in 705. Probably the son of Tiglath-Pileser III (r. 745–727), Sargon is generally believed to have become king after overthrowing Shalmaneser V (r. 727–722), probably his brother. He is typically considered the founder of a new dynastic line, the Sargonid dynasty.
Modelling his reign on the legends of the ancient rulers Sargon of Akkad, from whom Sargon II likely took his regnal name, and Gilgamesh, Sargon aspired to conquer the known world, initiate a golden age and a new world order, and be remembered and revered by future generations. Over the course of his seventeen-year reign, Sargon substantially expanded Assyrian territory and enacted important political and military reforms. An accomplished warrior-king and military strategist, Sargon personally led his troops into battle. By the end of his reign, all of his major enemies and rivals had been either defeated or pacified. Among Sargon's greatest accomplishments were the stabilization of Assyrian control over the Levant, the weakening of the northern kingdom of Urartu, and the reconquest of Babylonia. From 717 to 707, Sargon constructed a new Assyrian capital named after himself, Dur-Sharrukin ('Fort Sargon'), which he made his official residence in 706.
