" The hippie subculture was originally a youth movement that arose in the United States during the mid-1960s and spread to other countries around the world. Theetymology of the term 'hippie' is from hipster, and was initially used to describe beatniks who had moved into San Francisco's Haight-Ashbury district. Both the words "hip" and "hep" came from African American culture and denote "awareness".[1] The early hippies inherited the countercultural values of the Beat Generation, created their own communities, listened to psychedelic rock, embraced the sexual revolution, and some used drugs such as cannabis, LSD and magic mushrooms to explorealtered states of consciousness."
