12 May 1972
The South African Students' Organisation (SASO) adopted the "Alice Declaration" during a pre-arranged SASO meeting at the Federal Theological Seminary in Alice, Eastern Cape. The Declaration resolved that students nationwide should close down Black institutions of higher education through lecture boycotts in support of the expelled Onkgopotse Abram Tiro from the University of the North (now University of Limpopo, Turfloop Campus). Tiro had been expelled because of a graduation ceremony speech in which he had attacked segregated education and White domination of Black institutions.
