Yippies
Main article: Youth International PartyThe Yippies, who were seen as an offshoot of the hippie movements parodying as a political party, came to national attention during their celebration of the 1968 spring equinox, when some 3,000 of them took over Grand Central Station in New York — eventually resulting in 61 arrests. The Yippies, especially their leaders Abbie Hoffman and Jerry Rubin, became notorious for their theatrics, such as trying to levitate the Pentagon at the October 1967 war protest, and such slogans as "Rise up and abandon the creeping meatball!" Their stated intention to protest the 1968 Democratic National Convention in Chicago in August, including nominating their own candidate, "Lyndon Pigasus Pig" (an actual pig), was also widely publicized in the media at this time.
By the time of the convention, city officials were prepared for the worst, with 23,000 police, National Guard, and Federal troops. Following the pig's nomination on the first day, Rubin and 6 others were arrested, but protests and music concerts were allowed to continue in Lincoln Park for two days, albeit an 11:00 PM curfew was enforced. On the Convention's second night, poet Allan Ginsberg led protesters out of the park, thus avoiding confrontation, by chanting "Om". On the third night, riots erupted in response to the curfew, causing police to indiscriminately attack protesters and innocent bystanders alike, including journalists from around the world and even visiting dignitaries, throughout the streets of Chicago. The violence suffered by the journalists present, even including Mike Wallace, Dan Rather and Hugh Hefner, resulted in a mainstream media that was more sympathetic to certain hippie ideals, and less so to politicians, for several years. However, this galvanized the protest movement, and the following year, the trial of Hoffman, Rubin, and others as the "Chicago Seven" (originally Eight) generated significant interest.
