The earliest mention of the city of Babylon can be found in a tablet from the reign of Sargon of Akkad, dating back to the 23rd century BC. Following the collapse of the last Sumerian “Ur-III” dynasty at the hands of the Elamites (2002 BC traditional, 1940 BC short), the Amorites gained control over most of Mesopotamia, where they formed a series of small kingdoms. __
