Enannatum I
Enannatum I, son of Akurgal, succeeded his brother Eannatum as Ensi of Lagash. During his rule, Umma once more asserted independence under its ensi Ur-Lumma, who attacked Lagash unsuccessfully. After several battles, Enannatum I finally defeated Ur-Lumma. Ur-Lumma was replaced by a priest-king, Il, who also attacked Lagash.
