Ur-Nammu
Ur-Nammu (or Ur-Namma, Ur-Engur, Ur-Gur, ca. 2047-2030 BC short chronology) founded the Sumerian 3rd dynasty of Ur, in southern Mesopotamia, following several centuries of Akkadian and Gutian rule. His main achievement was state-building, and Ur-Nammu is chiefly remembered today for his legal code, the Code of Ur-Nammu, the oldest known surviving example in the world.
