The earliest kings in the Old Elamite period may date to approximately 2700 BC. Already conflict with Mesopotamia, in this case apparently with the city of Ur, was characteristic of Elamite history. These early rulers were succeeded by the Awan (Shustar) dynasty. The 11th king of this line entered into treaty relations with the great Naram-Sin of Akkad (c. 2254-c. 2218 BC). Yet there soon appeared a new ruling house, the Simash dynasty (Simash may have been in the mountains of southern Luristan). The outstanding event of this period was the virtual conquest of Elam by Shulgi of the 3rd dynasty of Ur (c. 2094-c. 2047 BC). Eventually the Elamites rose in rebellion and overthrew the 3rd Ur dynasty, an event long remembered in Mesopotamian dirges and omen texts. About the middle of the 19th century BC, power in Elam passed to a new dynasty, that of Eparti. The third king of this line, Shirukdukh, was active in various military coalitions against the rising power of Babylon, but Hammurabi (c. 1792-c. 1750 BC) was not to be denied, and Elam was crushed in 1764 BC. The Old Babylon kingdom, however, fell into rapid decline following the death of Hammurabi, and it was not long before the Elamites were able to gain revenge. Kutir-Nahhunte I attacked Samsuiluna (c. 1749-c. 1712 BC), Hammurabi’s son, and dealt so serious a defeat to the Babylonians that the event was remembered more than 1,000 years later in an inscription of the Assyrian king Ashurbanipal. It may be assumed that with this stroke Elam once again gained independence. The end of the Eparti dynasty, which may have come in the late 16th century BC, is buried in silence.
