Ur-Nammu (ŭr-nämˈō) [key], fl. 2060 B.C., king of the ancient city of Ur, sometimes called Zur-Nammu or Ur-Engur. He founded a new Sumerian dynasty, the third dynasty of Ur, that lasted a century. Ur-Nammu was the promulgator of the oldest code of law yet known, older by about three centuries than the code of Hammurabi. It consists of a prologue and seven laws; the prologue describes Ur-Nammu as a divinely appointed king who established justice throughout the land. This code is of great importance to the study of biblical law, which it predates by about five centuries. The two most famous monuments of Ur-Nammu's reign are the great ziggurat (temple) at Ur and his stele, of which fragments remain.
