[10][11][12] The twelve kings of Awan given in the list are: Pieli, Tari/ip, Ukkutahieš, Hišur, Šušuntarana, Na-?-pilhuš, Kikkutanteimti, Luhhiššan, Hišepratep, Hielu?, Hita-Idaddu-napir, Puzur-Inšušinak.

Little more of these kings' reigns is known, but Elam seems to have kept up a heavy trade with the Sumerian city-states during this time, importing mainly foods, and exporting cattle, wool, slaves and silver, among other things.

It is also known that the Awan kings carried out incursions in Mesopotamia, where they ran up against the most powerful city-states of this period, Kish and Lagash.

One such incident is recorded in a tablet addressed to Enetarzi, a minor ruler or governor of Lagash, testifying that a party of 600 Elamites had been intercepted and defeated while attempting to abscond from the port with plunder.

[13] Events become a little clearer at the time of the Akkadian Empire (c. 2300 BC), when historical texts tell of campaigns carried out by the kings of Akkad on the Iranian plateau.

Sargon of Akkad boasted of defeating a "Luh-ishan king of Elam, son of Hishiprashini", and mentions plunder seized from Awan, among other places.

This is confirmed by a document of great historical value, a peace treaty signed between Naram-Sin of Akkad and an unnamed king or governor of Awan, probably Khita or Helu.

The Elamites remained a major source of tension, that would contribute to destabilizing the Akkadian state, until it finally collapsed under Gutian pressure.

When the Akkadian empire started to break down around 2240 BC, it was Kutik-Inshushinak (or Puzur-Inshushinak), the governor of Susa on behalf of Akkad, who liberated Awan and Elam, ascending to the throne.
