The Early Dynastic period was brought to an end when Sargon (2334-2279) created the world's first empire, stretching the length and breadth of the fertile crescent. The impact of Sargon's unification of Sumer and Akkad resonated down through the history of Mesopotamia for the next two thousand years.
