Third Dynasty of Ur
The Third Dynasty of Ur is dated to c. 2047–1940 BC short chronology. Ur-Nammu of Ur defeated Utu-hegal of Uruk and founded the Third Dynasty of Ur. Although the Sumerian language ("Emegir") was again made official, Sumerian identity was already in decline, as the population became continually absorbed into the Akkadian (Assyro-Babylonian) population.
