History of Sumer

The history of Sumer, taken to include the prehistoric Ubaid and Uruk periods, spans the 5th to 3rd millenia BC, ending with the downfall of the Third Dynasty of Ur around 2004 BC, followed by a transition period of Amorite states before the rise of Babylonia in the 18th century BC. The first settlement in southern Mesopotamia was Eridu. The Sumerians claimed that their civilization had been brought, fully formed, to the city of Eridu by their god Enki or by his advisor (or Abgallu from ab=water, gal=big, lu=man), Adapa U-an (the Oannes of Berossus). The first people at Eridu brought with them the Samarran culture from northern Mesopotamia and are identified with the Ubaid period, but it is not known whether or not these were Sumerians (associated later with the Uruk period). The Sumerian king list is an ancient text in the Sumerian language listing kings of Sumer from Sumerian and foreign dynasties. Some of the earlier dynasties may be mythical; and only a few of the early names have been authenticated through archaeology. The best-known dynasty, that of Lagash, is not listed there at all.
