<P> Charles Manson was a lifelong criminal who had been released from prison just in time for San Francisco's Summer of Love . With his long hair, charisma and the ability to charm a crowd with his guitar playing, his singing and rhetoric, Manson exhibited many of the outward manifestations of hippie identity . Yet he hardly exemplified the hippie ideals of peace, love, compassion and human fellowship; through twisted logic, hallucinogenic drugs, and psychological manipulation, he inspired his followers to commit murder . Manson's highly publicized 1970 trial and subsequent conviction in January 1971 irrevocably tarnished the hippie image in the eyes of many Americans . </P> <P> Also around this time, John Lennon of the Beatles and his wife Yoko Ono took up the mantle of a more prominent media role, as a force for continuing the' humane revolution' that was politically opposed to the' establishment' . As early as March 1969 the couple had conducted their first "Bed - In for Peace"; in August 1971 they moved to New York City and joined up with the Chicago Trial "Yippie" defendants and other notable activists . In December 1971, Lennon sang at the John Sinclair Freedom Rally in Michigan, calling attention to Sinclair's ten - year prison sentence for giving two joints to an undercover policewoman . Sinclair's release was suddenly approved by the state's authorities three days later, a testimony to the potential force of popular pressure; however, soon thereafter, the Nixon administration responded by seeking to have Lennon deported, on the pretext of a 1968 marijuana conviction in London . This dragged on through half of 1973, only increasing their status as anti-war and counterculture celebrities; by June 1973, the Watergate hearings had begun in earnest, and the famous pair made their final political statement by attending one of them . In 1975, the deportation case was dropped, and Lennon and Yoko attended the Inaugural Ball of president Jimmy Carter in January 1977 . </P> <P> Much of hippie style had been integrated into mainstream American society by the early 1970s . Large rock concerts that originated with the 1967 Monterey Pop Festival and the 1968 Isle of Wight Festival became the norm . Mustaches, beards, sideburns, and longer hair became mainstream, and colorful, multi-ethnic clothing dominated the fashion world . </P> <P> Starting in the late 1960s, some working class skinheads have attacked hippies . Hippies were also vilified and sometimes attacked by punks, revivalist mods, greasers, football casuals, Teddy Boys and members of other American and European youth cultures in the 1970s and 1980s . Hippie ideals were a marked influence on anarcho - punk and some post-punk youth cultures, such as the Second Summer of Love . </P>

When did the hippie movement start and end
