The Students for a Democratic Society (SDS) was formed in 1959 as a breakaway group from an existing student organization. The SDS was a radical student group comprised of teens and young adults that aimed to promote social change. They opposed the Vietnam War and fought for various civil rights causes. The SDS helped spark student activism on college campuses across the U.S. in the 1960s before ultimately dissolving in 1969 due to internal disagreements.
