Submission of Sumerian kings

The submission of some Sumerian rulers to the Akkadian Empire, is recorded in the seal inscriptions of Sumerian rulers such as Lugal-ushumgal, governor (ensi) of Lagash ("Shirpula"), circa 2230–2210 BC. Several inscriptions of Lugal-ushumgal are known, particularly seal impressions, which refer to him as governor of Lagash and at the time a vassal (𒀵, arad, "servant" or "slave") of Naram-Sin, as well as his successor Shar-kali-sharri. One of these seals proclaims:

“Naram-Sin, the mighty God of Agade, king of the four corners of the world, Lugal-ushumgal, the scribe, ensi of Lagash, is thy servant.”

It can be considered that Lugal-ushumgal was a collaborator of the Akkadian Empire, as was Meskigal, ruler of Adab. Later however, Lugal-ushumgal was succeeded by Puzer-Mama who, as Akkadian power waned, achieved independence from Shar-Kali-Sharri, assuming the title of "King of Lagash" and starting the illustrious Second Dynasty of Lagash.
