 One inscription found on a boulder states that Eannatum was his Sumerian name, while his "Tidnu" (Amorite) name was "Lumma".Eannatum, grandson of Ur-Nanshe and son of Akurgal, was a king of Lagash who conquered all of Sumer, including Ur, Nippur, Akshak (controlled by Zuzu), Larsa, and Uruk (controlled by Enshakushanna, who is on the King List).He entered into conflict with Umma, waging a war over the fertile plain of Gu-Edin.
