Renaissance of Sumer
The Renaissance of Sumer is a period of the history of Mesopotamia that includes the years between the fall of the Akkadian Empire and the period of the Amorite dynasties of Isin and Larsa—both with governments of Semitic origin—between the centuries 22nd B.C. and 21st B.C. Within this stage the years of the so-called Third Dynasty of Ur or "Ur III" stand out, because of the new hegemony that would embrace all Mesopotamia, this time with the city of Ur at the head. == Sumer survives the Gutian invasion == Despite the irruption of the nomadic gutians, who provoked continuous plundering, razed cities and fields, and made trade difficult, the end of the Akkadian Empire did not bring decadence, at least in the southern part of Mesopotamia.
