Charles Milles Manson was an American criminal and cult leader. In mid-1967, he formed what became known as the "Manson Family", a quasi-commune based in California. His followers committed a series of nine murders at four locations in July and August 1969. Although the motive for the murders was disputed by Manson, the Los Angeles County District Attorney believed that Manson intended to start a race war. In 1971, he was convicted of first-degree murder and conspiracy to commit murder for the deaths of seven people, including the film actress Sharon Tate. The prosecution contended that, while Manson never directly ordered the murders, his ideology constituted an overt act of conspiracy.
