Hammurabi, or Hammurapi, sixth king of the first dynasty of Babylonia (r. 1792–50 B.C.). He conquered and united Mesopotamia, establishing an empire that did not long survive him. He was responsible for the Code of Hammurabi, the fullest known collection of Babylonian laws. The best source of the code is a black stone column found at Susa, Iran, in 1901.
