Further student protests, including hunger strike and more barricades of Hamilton Hall and the Business School during the late 1970s and early 1980s, were aimed at convincing the university trustees to divest all of the university's investments in companies that were seen as active or tacit supporters of the apartheid regime in South Africa. A notable upsurge in the protests occurred in 1978, when following a celebration of the tenth anniversary of the student uprising in 1968, students marched and rallied in protest of university investments in South Africa. The Committee Against Investment in South Africa (CAISA) and numerous student groups including the Socialist Action Committee, the Black Student Organization and the Gay Students group joined together and succeeded in pressing for the first partial divestment of a U.S. university.
