He secured a scholarship, and in 1966 entered the University of Natal Medical School. There, he joined what his biographer Xolela Mangcu called "a peculiarly sophisticated and cosmopolitan group of students" from across South Africa; many of them later held prominent roles in the post-apartheid era. The late 1960s was the heyday of radical student politics across the world, as reflected in the protests of 1968, and Biko was eager to involve himself in this environment. Soon after he arrived at the university, he was elected to the Students' Representative Council (SRC). The university's SRC was affiliated with the National Union of South African Students (NUSAS). NUSAS had taken pains to cultivate a multi-racial membership but remained white-dominated because the majority of South Africa's students were from the country's white minority. As Clive Nettleton, a white NUSAS leader, put it: "the essence of the matter is that NUSAS was founded on white initiative, is financed by white money and reflects the opinions of the majority of its members who are white". NUSAS officially opposed apartheid, but it moderated its opposition in order to maintain the support of conservative white students. Biko and several other black African NUSAS members were frustrated when it organised parties in white dormitories, which black Africans were forbidden to enter. In July 1967, a NUSAS conference was held at Rhodes University in Grahamstown; after the students arrived, they found that dormitory accommodation had been arranged for the white and Indian delegates but not the black Africans, who were told that they could sleep in a local church. Biko and other black African delegates walked out of the conference in anger. Biko later related that this event forced him to rethink his belief in the multi-racial approach to political activism: Founding the South African Students' Organisation: 1968–1972 Developing SASO Following the 1968 NUSAS conference in Johannesburg, many of its members attended a July 1968 conference of the University Christian Movement at Stutterheim. There, the black African members decided to hold a December conference to discuss the formation of an independent black student group. The South African Students' Organisation (SASO) was officially launched at a July 1969 conference at the University of the North; there, the group's constitution and basic policy platform were adopted. The group's focus was on the need for contact between centres of black student activity, including through sport, cultural activities, and debating competitions. Though
