In 1948, the National Party came to power in South Africa, and began to implement the policy of apartheid. Apartheid as a doctrine envisaged the total segregation of races in South Africa, and East London was no different. In 1950, the Group Areas Act was placed upon the statute books making absolute segregation in all urban areas mandatory. In 1951, the Land Tenure Advisory Board, the body created to enforce the act, conducted initial investigations into the reallocation of space along racial lines in East London. Residential segregation had long been practised in East London prior to the advent of apartheid. In 1941, the East London Municipality moved residents from East Bank townships to the newly built township of Duncan Village.
