Students for a Democratic Society, aka SDS, was founded in 1960 and became the most influential student organization of the 1960s "New Left," until its fracturing into various competing sects in 1969. It opposed the Vietham War, supported the African American civil rights movement, academic freedom, and an end to college and university supervision and policing of the private lives and social mores of students.
