An apocalyptic race war will arise

Charles Manson : musician, criminal
Manson believed in what he called "Helter Skelter," a term he took from the song of the same name by The Beatles. Manson believed Helter Skelter to be an impending apocalyptic race war, which he described in his own version of the lyrics to the Beatles' song. He believed his murders would help precipitate that war. From the beginning of his notoriety, a pop culture arose around him in which he ultimately became an emblem of insanity, violence and the macabre. The term was later used by Manson prosecutor Vincent Bugliosi as the title of a book he wrote about the Manson murders.
