Irkab-Damu (=Yirkab-Damu) in Wikipedida
Irkab-Damu (ca. 23rd century BC) was a king of the ancient city-state of Ebla.
He sent the commander of his army Enna-Dagan to overthrow the powerful coalition formed by Iblul-Il, king of Mari. This was successful and Enna-Dagan took the title of Lugal - the title lugal, literally "great man", meant king in other parts of Mesopotamia, but in Ebla it was used for the title governor. Iblul-Il was allowed to return to Mari as a governor.
