Ukush

Ukush is known from the Nippur vase inscription of Lugal-Zage-Si:

Other inscriptions, such as an inscription on a brick with a central hole in the Bible Lands Museum, also mention Lugalzagesi as "son of Ukush" (𒌉 𒌑𒌑, dumu u2-u2). Another dedicatory inscription is also known.

It is thought that he played an important role in making Umma a strong city with a powerful army, which allowed his son to achieve the defeat of neighbouring and traditional rival Lagash and its king Urukagina, and then the conquest of all Sumer.
