Ur-Lumma again entered in a territorial conflict with Lagash, for the fertile plain of Gu-Edin.[6] Ur-Lumma, attacked Lagash and its king Enannatum, successor of Eannatum, managing to "destroy with fire the stele of Eannatum and the shrines of the gods set up beside it". Ur-Lumma vanquished Enannatum and occupied Lagash, but he was eventually repelled by Entemena, the son of Enannatum.[7][8]
Ur-Lumma was replaced by his nephew Illi, a priest-king, who also attacked Lagash, but was again defeated by Entemena.[8]
