The Old Elamite period begins around 2700 BCE.

Historical records mention the conquest of Elam by Enmebaragesi the Sumerian king of Kish.

Three dynasties rule during this period.

We know of twelve kings of each of the first two dynasties, those of Awan (or Avan; c. 2400–2100 BCE) and Simash (c. 2100–1970 BCE), from a list from Susa dating to the Old Babylonian period.

Two Elamite dynasties said to have exercised brief control over parts of Sumer in very early times include Awan and Hamazi; and likewise, several of the stronger Sumerian rulers, such as Eannatum of Lagash and Lugal-anne-mundu of Adab, are recorded as temporarily dominating Elam.
