Fringe and conspiracy theories about the death of Adolf Hitler, dictator of Germany from 1933 to 1945, contradict the accepted fact that he committed suicide in the Führerbunker on 30 April 1945. Stemming from a campaign of Soviet disinformation, most of these theories hold that Hitler and his wife, Eva Braun, survived and escaped from Berlin, with some asserting that he went to South America. In the post-war years, the United States Federal Bureau of Investigation (FBI) and Central Intelligence Agency (CIA) investigated some of the reports, without lending them credence. The 2009 revelation that a skull in the Soviet archives long (dubiously) claimed to be Hitler's actually belonged to a woman has helped fuel fringe theories.
While the claims have received some exposure in popular culture, they are regarded by historians and scientific experts as disproven conspiracy theories. Eyewitnesses and Hitler's dental remains demonstrate that he died in his Berlin bunker in 1945.
