 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.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.
