Akhenaten was an ancient Egyptian pharaoh. He was founder of Atenism and is believed to the father of the Abrahamic religions.
While he allowed the traditional Egyptian faith for many years, something occurred, that caused Akhenaten to snap and suppress the worship of other traditional Ancient Egyptian gods, except Ra, which he equated with Aten, the only deity in his own religon.
After his death, Akhenaten was deleted from many Egyptian records, only referring to him as "The Enemy" or "The Criminal."
