The Awan Dynasty was the first dynasty of Elam of which anything is known today, appearing at the dawn of historical record. The Elamites were likely major rivals of neighboring Sumer from remotest antiquity; they were said to have been defeated by Enmebaragesi of Kish (ca. 25th century BC), who is the earliest archaeologically attested Sumerian king, as well as by a later monarch, Eannatum I of Lagash.
Awan was a city or possibly a region of Elam whose precise location is not certain, but it has been variously conjectured to be north of Susa, in south Luristan, close to Dezful, or Godin Tepe.
