Sumu-abum
Sumu-Abum was an Amorite, and the first King of the First Dynasty of Babylon. He reigned from 1830-1817 BC / 1897-1883 BC.
He freed a small area of land previously ruled by the fellow Amorite city state of Kazallu which included Babylon, then a minor administrative center in southern Mesopotamia. Sumu-Abum makes no claim to be King of Babylon, suggesting that the town was at this time still of little importance.
