Amraphel, king of Shinar, southern Chaldea, one of the confederates of Chedorlaomer, king of Elam, in a war against Sodom and cities of the plain (Genesis 14:1,4). It is now found that Amraphel (or Ammirapaltu) is the Khammu-rabi whose name appears on recently-discovered monuments. (See CHEDORLAOMER). After defeating Arioch (q.v.) he united Babylonia under one rule, and made Babylon his capital.
