A supreme leader or supreme ruler typically refers to the person among a number of leaders of a state, organization or other such group who has been given or is able to exercise the most – or complete – authority over it. In a religion, this role is usually satisfied by a person deemed to be the representative or manifestation of a deity or God on Earth. In politics, a supreme leader usually rules over an authoritarian or totalitarian government and has a cult of personality associated with them. Historic examples are Adolf Hitler of Nazi Germany, Francisco Franco of Francoist Spain, Benito Mussolini of Fascist Italy and Joseph Stalin of the Soviet Union.
