What is "kullassina-bel"

Kullassina-bel of Kish was the second king in the First Dynasty of Kish according to the Sumerian king list, which adds that he reigned for 960 years (or 900 in some copies).

As the name seems to be an Akkadian phrase meaning "All of them (were) lord", it has sometimes been suggested that the occurrence of this name on the list was intended to denote a period of no central authority in the early period of Kish. The following kings of Kish on the list preceding Etana are all names of animals, such as Zuqaqip (scorpion).
