Simurrum was an important city state of the Mesopotamian area from around 2000 BCE to 1500 BCE, during the period of the Akkadian Empire down to Ur III. The Simurrum Kingdom disappears from records after the Old Babylonian period. It is thought that in Old Babylonian times its name was Zabban, a notable cult center of Adad. It was neighbor and sometimes ally with the Lullubi kingdom.

Ibbi-Sin, son of Shu-Sin, was king of Sumer and Akkad and last king of the Ur III dynasty, and reigned c. 2028–2004 BCE or possibly c. 1964–1940 BCE. During his reign, the Sumerian empire was attacked repeatedly by Amorites. As faith in Ibbi-Sin's leadership failed, Elam declared its independence and began to raid as well.
