From The Art and Popular Culture Encyclopedia
Hippie refers to a subgroup of the 1960s and early 1970s counterculture that found its earliest beginnings in the North American counterculture, becoming an established social group by 1965 before declining during the mid-1970s. The hippie dream of peace and love was shattered in 1970 with the events at Altamont, the Manson murders and the deaths of Jimi Hendrix and Janis Joplin.
