The native princes of southern Babylonia resisted it, and the Elamites harried the country with fire and sword.

In B.C.2280 Kudur-Nankhundi, the Elamite king, sacked Erech and carried away the image of its goddess, and not long afterwards we find another Elamite king, Kudur-Laghghamar or Chedor-laomer, claiming lordship over the whole of Chaldsea.

The western provinces of Babylonia shared in the fate of the sovereign power, and an Elamite prince, Kudur-Mabug by name, was made "Father" or "Governor of the land of the Amorites." His son Eri-Aku, the Arioch of Genesis, was given the title of king in southern Babylonia, with Larsa as his capital.

Larsa had been taken by storm by the Elamite forces, and its native king, Sin-idinnam, driven out.

He fled for refuge to the court of the King of Babylon, who still preserved a semblance of authority.
Khammurabi or Amraphel, the fifth successor of Sumu-abi, was now on the throne of Babylon.
