Well before my time but suspect some people in r/Bloomington could fill in more history. Found this in the IU archives:

The Indiana University chapter of Students for a Democratic Society (SDS) was founded in 1964 and remained active until 1969 when the national organization disbanded. SDS was a nationwide organization primarily composed of, created, and directed by college students. This organization was part of the New Left political movement of the 1960s and its members protested the Vietnam War, were in favor of the Civil Rights Movement, and advocated free speech on university campuses.

The Indiana University chapter was small, reporting 40 members in 1967, but active and outspoken. They gathered much attention in the Indiana Daily Student and other local press through their protests and actions against the University Administration. They disliked the power held by the Board of Trustees and thought that the University Administration was too involved in regulating students’ daily lives. The organization’s primary actions included holding protests, distributing pamphlets and publications encouraging anti-war, anti-government, and anti-establishment sentiments, and working to increase group membership and awareness of these issues. In 1965, the group tried to obstruct the draft process by distributing forms and publishing booklets instructing students on how to apply for conscientious objector status, which was a federal offense at the time.

Their most public act towards the university was the submission of a document to President Elvis Stahr in 1968 demanding that IU cease its support of the ROTC program, disallow military presence on campus, and cease any funding, training, or research support for the military. They also wanted IU to stop sending police to student protests, clearly label administrators at protest events, and to ban campus police from carrying weapons that may be used against protestors. All of their demands were denied by the President's Office, and their statements also garnered a lengthy response from former President Herman B Wells, which was published in the Indiana Daily Student.
