When did the hippie movement begin?

A hippie (sometimes misspelled as hippy) is a member of the counterculture of the 1960s, originally a youth movement that began in the United States during the mid-1960s and spread to other countries around the world. The word hippie came from hipster and was used to describe beatniks who moved into New York City's Greenwich Village, San Francisco's Haight-Ashbury district, and Chicago's Old Town community. The term hippie first found popularity in San Francisco with Herb Caen, who was a journalist for the San Francisco Chronicle.

The origins of the terms hip and hep are uncertain. By the 1940s, both had become part of African American jive slang and meant "sophisticated; currently fashionable; fully up-to-date". The Beats adopted the term hip, and early hippies inherited the language and countercultural values of the Beat Generation. Hippies created their own communities, listened to psychedelic music, embraced the sexual revolution, and many used drugs such as marijuana and LSD to explore altered states of consciousness.
