Step-by-step explanation:
The Students for a Democratic Society (SDS) was a major student organization that spearheaded protests and demonstrations against the Vietnam War. In April 1965, the SDS organized a significant antiwar march in Washington D.C., which drew in about 20,000 participants.
The march reflected the increasing antiwar sentiment across college campuses and was a part of a widespread student movement that included other forms of protest such as "teach-ins." As the movement gained momentum, it embraced a diverse group of supporters, including scholars, labor leaders, minorities, and veterans, all advocating for the end of U.S. involvement in Vietnam.
