While the Sumerian princes were engaged in mutual war, the Semites were occupying northern Babylonia, and establishing their power in the city of Agadê or Akkad, not far from Sippara. Here, in B.C. 3800, arose the empire of Sargani-sar-ali, better known to posterity as "Sargon" of Akkad. He became the hero of the Semitic race in Babylonia.
