1970, the hippie movement began to wane. The events at the Alatamont Free concert shocked many people including some who had supported the hippie movement. Several hippie mega-stars, including Jimi Hendrix, Janis Joplin, and Jim Morrison, overdosed on drugs. The Charles Manson murders also contributed to the public hatred of the hippies. Soon, hippies were being physically attacked on the streets by skinheads, punks, athletes, greasers, and members of other youth subcultures.
