En-shag-kush-ana

Enshakushanna (or En-shag-kush-ana, Enukduanna, En-Shakansha-Ana) was a king of Uruk in the later 3rd millennium BC who is named on the Sumerian king list, which states his reign to have been 60 years. He conquered Hamazi, Akkad, Kish, and Nippur, claiming hegemony over all of Sumer. He adopted the Sumerian title en ki-en-gi lugal kalam-ma, which may be translated as "lord of Sumer and king of all the land" (or possibly as "en of the region of Uruk and lugal of the region of Ur"), and could correspond to the later title lugal ki-en-gi ki-uri "King of Sumer and Akkad" that eventually came to signify kingship over Mesopotamia as a whole.

He was succeeded in Uruk by Lugal-kinishe-dudu, but the hegemony seems to have passed to Eannatum of Lagash for a time. Lugal-kinishe-dudu was later allied with Entemena, a successor of Eannatum, against Lagash's principal rival, Umma.
