The Sixties in the United States was a time of extreme political involvement for many. Many other countries saw similar activity, such as France with the Situationist Movement, but in the Unites States perhaps the most memorable and widespread were the civil rights and student activism that came about during this period. Students and youth, opposed to the military intervention in Vietnam as well as the mainstream liberalism and social conservatism that they saw, created a counter-cultural movement that sparked social revolution across the west. Central among their many issues were rights for women and minorities. These groups, such as Students for a Democratic Society (SDS) and Student Nonviolent Coordinating Committee (SNCC), used such tools as the strike, rallies, marches, sit-ins, posters, film and an extremely active underground press to spread their message.
