Members of a movement of cultural protest that began in the United States in the 1960s and affected Europe before fading in the 1970s. Hippies were bound together by rejection of many standard American customs and social and political views (see counterculture). The hippies often cultivated an unkempt image in their dress and grooming and were known for practices such as communal living, free love, and the use of marijuana and other drugs. Although hippies were usually opposed to involvement of the United States in the Vietnam War, their movement was fundamentally a cultural rather than a political protest. (See Woodstock; compare beatniks.)
