A Wits-initiated research project, Perspectives of Wits (POW), published in 1986, revealed a surprising disconnect between the perceptions disadvantaged communities had of Wits and the image Wits had been attempting to convey of itself as a progressive opponent of apartheid. To many in the surrounding disadvantaged communities, there was a perception of Wits as an elitist institution dominated by white interests. A need was identified for further transformation of the university. instead of translating POW's proposals into institutional plans for transformation, Wits reacted in a defensive manner and refused to even acknowledge many of the criticisms that had been raised. Within the university community the perception was different—it was felt that Wits was on the right track. The contradiction between internal and external perceptions would increasingly undermine the unity of the university community, as progressive elements on campus began to take more radical positions in opposition to apartheid. The 1980s saw numerous protests on campus, which often ended with police invasions of the university. In 1990, when Nelson Mandela was released, the students of Men's Res, on East Campus, unofficially renamed the lawn outside their residence "Mandela Square".
