Conquest of Sumer

In the inscription, Sargon styles himself "Sargon, king of Akkad, overseer (mashkim) of Inanna, king of Kish, anointed (guda) of Anu, king of the land, governor (ensi) of Enlil". It celebrates the conquest of Uruk and the defeat of Lugalzagesi, whom Sargon brought "in a collar to the gate of Enlil":
