Conspiracy theories about Adolf Hitler's death

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. Largely stemming from a campaign of Soviet disinformation, most of these theories hold that Hitler and his wife, Eva Braun, survived and escaped from Berlin, typically asserting that he fled to South America.

In the post-war years, the United States Federal Bureau of Investigation (FBI) and Central Intelligence Agency (CIA) investigated related reports and an alleged photograph but did not endorse their veracity. The 21st-century declassification of these files has helped fuel fringe theories, in addition to the revelation that a skull in the Soviet archives purported to be Hitler's actually belonged to a woman.

The claims have received some exposure in popular culture, but are regarded by historians and scientific experts as being disproven by the hard evidence of Hitler's dental remains (including teeth on a mandibular fragment, the only part of his body confirmed) and certain eyewitness accounts.
