movement. No one joined and there were no set guidelines to becoming a hippie. It was, in fact, a yourthful subculture that began in the United States and quickly became an international phenomena. The two most renowned early hotspots for the movement were in Greenwich Village (New York City) and the Haight-Ashbury district (San Francisco). The word "hippie" derived from the word "hipster," which evolved as a later synonym for "beatnik"--the youth who followed the ways and customs of the Beat Generation. Hippies generally wore their hair long, dressed colorfully and unconventionally, listened to the most modern rock music (especially psychedelic and hard rock), used drugs freely and often, and embraced sexual freedom. The transition to the hippie subculture was a conscious decision in response to the restrictions of parents or conservative upbringing. Youthful opposition to the Vietnam War was another motivation. Events such as the Be-In in San Francisco's Golden Gate Park in early 1967 and the year's later Summer of Love, and the 1969 Woodstock Festival in New York came to define the movement. The advent of the hippie effected the world's culture significantly, particularly with the burgeoning rock music scene, but the hippie culture became visible on TV, movies, health foods, fashion, art and literature.
