Between 1966 and 1968, Northwestern increased African American enrollments from less than 50 to 160. After the assassination of Martin Luther King, Jr. in April 1968, African American students on campus began expressing increasingly militant and separatist views demanding the administration increase recruitment activity and provide separate facilities for black students. After the university rejected their demands, on May 3, 1968, a group of 100 African American students identifying themselves as For Members Only and the Afro-American Student Union barricaded themselves the Bursar's Office and began a sit-in, demanding the university implement an admissions quota, increase financial aid, construct an all-black dorm and student center, create a Black Studies curriculum, and desegregate the university's real estate holdings in Evanston. In light of controversy surrounding the student protests at Columbia and Berkeley that spring, negotiations between Dean of Students Roland Hinz and AASU leader James Turner led to the sit-in dispersing peacefully after 38 hours. Although the administration rejected demands for racial preferences in admissions and financial aid, it made several concessions regarding desegregation, increasing student participation in policy matters, and developing a Department of African-American Studies.
