Akhenaton, Egyptian pharaoh and religious reformer, ruled 1370-50.
Fishburn and Hughes: "An Egyptian Pharaoh and religious reformer who introduced the monotheistic cult of Aton, the sun disc. Aton took the place of all other divinities. His worship was free of all moral codes and of the austerity demanded by former Egyptian cults. Amenophis's liberal reform of religious expression did not survive him long." (9)
