===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 (Sumerian)|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 ({{cuneiform|6|𒀵}}, ''arad'', "servant" or "slave") of Naram-Sin, as well as his successor [[Shar-kali-sharri]].<ref>{{cite web |title=Sumerian Dictionary |url=http://oracc.iaas.upenn.edu/epsd2/cbd/sux/A.html |website=oracc.iaas.upenn.edu}}</ref><ref name="HR"/><ref>{{cite book |last1=Woolley |first1=Leonard |title=The Summerians |date=1938 |page=[https://archive.org/details/in.ernet.dli.2015.166848/page/n130 83] |url=https://archive.org/details/in.ernet.dli.2015.166848}}</ref><ref>{{cite book |title=The Art Of Ancient Mesopotamia ( Art Ebook) |page=53}}</ref> One of these seals proclaims:

It can be considered that Lugal-ushumgal was a collaborator of the Akkadian Empire, as was [[Meskigal]], ruler of [[Adab (city)|Adab]].<ref>{{cite book |title=The Cambridge Ancient History |date=1971 |publisher=Cambridge University Press |page=436 |isbn=9780521077910 |url=https://books.google.com/books?id=KorxAAAAMAAJ}}</ref> 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.<ref>{{cite book |last1=Álvarez-Mon |first1=Javier |last2=Basello |first2=Gian Pietro |last3=Wicks |first3=Yasmina |title=The Elamite World |date=2018 |publisher=Routledge |isbn=978-1-317-32983-1 |page=254 |url=https://books.google.com/books?id=yClKDwAAQBAJ&pg=PT254 |language=en}}</ref><ref>{{cite book |title=The Cambridge Ancient History |date=1971 |publisher=Cambridge University Press |page=998 |isbn=9780521077910 |url=https://books.google.com/books?id=KorxAAAAMAAJ}}</ref>
