15 April 1954
African National Congress (ANC) member Walter Sisulu acted as speaker at a meeting of the organisation held in Sophiatown, Johannesburg. This was in defiance of the forced removal of Blacks in places earmarked for Whites only. Sisulu urged the Blacks not to allow themselves to be removed from the Western areas. This came after a series of legislation was enacted, aimed at segregating Black and White residential areas.
