Kubaba
Kubaba (in the Weidner or Esagila Chronicle; Sumerian: Kug-Bau) is the only queen on the Sumerian King List, which states she reigned for 100 years – roughly in the Early Dynastic III period (ca. 2500-2330 BC) of Sumerian history. Most versions of the king list place her alone in her own dynasty, the 3rd Dynasty of Kish, following the defeat of Sharrumiter of Mari, but other versions combine her with the 4th dynasty, that followed the primacy of the king of Akshak. Before becoming monarch, the king list says she was a tavern-keeper.
