The Manson Family (known among its members as the Family) was a commune, gang, and cult led by Charles Manson that was active in California in the late 1960s and early 1970s. The group consisted of approximately 100 followers, who lived an unconventional lifestyle with habitual use of hallucinogenic drugs such as LSD. Most were young women from middle-class backgrounds, many of whom were radicalized by Manson's teachings and drawn by hippie culture and communal living.Soon after release from prison in 1967, Manson, who had been institutionalized or incarcerated for more than half of his life, began attracting acolytes in the San Francisco-area. They gradually moved to a run-down ranch, called the Spahn Ranch in Los Angeles County. The ranch burned down during a Southern California wildfire in September 1970. According to group member Susan Atkins, the members of the Family were convinced that Manson was a manifestation of Jesus Christ and believed in his prophecies concerning an imminent, apocalyptic race war.In 1969, Family members Susan Atkins, Tex Watson, and Patricia Krenwinkel entered the home of Hollywood actress Sharon Tate and murdered her and four others. Linda Kasabian was also present, but did not take part. Members of the Manson Family were also responsible for a number of other murders, assaults, petty crimes, and thefts.
