Dwight D. York (b. 1945), also known as Malachi Z. York, Issa Al Haadi Al Mahdi and Dr. York, is an American musician and writer who is known as the founding leader of various religious/political groups, including most notably the cult Nuwaubian movement. York began his ministry in the late 1960s. In 1967 he was preaching to the 'Ansaaru Allah' (viz. African Americans) in Brooklyn, New York, during the period of the Black Power movement. He founded numerous orders under various names during the 1970s and 1980s. These were at first based on pseudo-Islamic themes and Judaism (Nubian Islamic Hebrews). Later he developed a theme derived from 'Ancient Egypt,' mixing ideas taken from black nationalism, cryptozoological and UFO religions, and popular conspiracy theory. He last called his group the United Nuwaubian Nation of Moors, or Nuwabians.
