Sargon of Akkad
Lagash finally fell to Lugalzagesi, king of Umma, circa 2350 BCE, ending the First Dynasty of Lagash. Tablets of lamentation have been found, recording the fall of Lagash to Lugalzagesi, during the rule of Urukagina. Lugalzagesi went on to conquer the whole of Sumer, until he was himself vanquished by Sargon of Akkad.
