Subcultures were often based on socializing and wild behaviour, but some of them were centred around politics. In the United States, these included the Black Panthers and the Yippies. Allen Ginsberg took part in several protest movements, including those for gay rights and those against the Vietnam War and nuclear weapons. In Paris, France in May 1968, there was a university student uprising, supported by Jean-Paul Sartre and 121 other intellectuals who signed a statement asserting "the right to disobedience." The uprising brought the country to a standstill, and caused the government to call a general election rather than run the risk of being toppled from power.
