78:8.7

After the breakup of the early Sumerian confederation the later city-states were ruled by the apostate descendants of the Sethite priests. Only when these priests made conquests of the neighboring cities did they call themselves kings. The later city kings failed to form powerful confederations before the days of Sargon because of deity jealousy. Each city believed its municipal god to be superior to all other gods, and therefore they refused to subordinate themselves to a common leader.
