Articles related to the Third Dynasty of Ur (c. 2112 BC – c. 2004 BC), a Sumerian ruling dynasty based in the city of Ur, and to its short-lived territorial-political state which some historians consider to have been a nascent empire. The Third Dynasty of Ur was the last Sumerian dynasty which came to preeminent power in Mesopotamia. It began after several centuries of control by Akkadian and Gutian kings. It controlled the cities of Isin, Larsa, and Eshnunna and extended as far north as Upper Mesopotamia. The dynasty corresponded to a Sumerian renaissance following the fall of the First Dynasty of Ur.
