Hippies emerged in the 1960s as a countercultural movement that rejected mainstream American values. They advocated peace, love, anti-materialism, and free expression. Key figures and bands represented the hippie movement including The Beatles, Janis Joplin, The Doors, and The Jaivas, who fused indigenous Latin American music with rock. The movement began to decline after events like the Altamont Free Concert and Charles Manson murders in the late 1960s.
