Kubaba

Kubaba (in the Weidner "Chronicle"), also known as Kug-Baba or Kubau, is the only queen on the Sumerian king list. Before overthrowing the rule of En-Shakansha-Ana of the 2nd Uruk Dynasty and becoming monarch, the king list says she was a tavern-keeper. "The house of Kubaba" is mentioned "in the reign of Puzur-Nirah, king of Akshak" (line 38) in the Weidner "Chronicle", a propagandistic letter attempting to predate the shrine of Marduk to an early period: "Kubaba gave bread to the fisherman and gave water, she made him offer the fish to Esagila" (line 43). Her reign as the only "king" of the 3rd Dynasty of Kish was one of peace and prosperity. Her reign is contemporary with the "Early Dynastic III" period of Sumer. Her reign is listed to have lasted for 100 years. If she is a historical ruler, she probably lived in the 23rd to 25th century BC.
