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.
The rise of the first cities in southern Mesopotamia dates to the Chalcolithic (Uruk period), from c. 5300 BC; its regional independence ended with the Achaemenid conquest in 539 BC, although a few native neo-Assyrian kingdoms existed at different times, namely Adiabene, Osroene and Hatra.
