The Hippie Movement was a youth counterculture that emerged in the United States during the mid-1960s. It originated from the Beat Generation and had important bases in San Francisco and Berkeley, California. The movement promoted ideals of peace, love, environmentalism, and libertarian socialism. Famous hippies included musicians like Jimi Hendrix, Janis Joplin, and members of the Grateful Dead and Beatles. Major hippie events included the 1967 Human Be-In and the 1969 Woodstock Festival. However, the movement declined after events like Altamont and due to integration into mainstream society.
