Answer: when Nelson Mandela was growing up, there was a society where racism and segregation were all around the country. there was a policy called Apartheid which means segregation; lit. "separateness". It was a system of institutionalised racial segregation that existed in South Africa and South West Africa (Namibia) from 1948 until the early 1990s. Apartheid was characterised by an authoritarian political culture based on baasskap (or white supremacy), which encouraged state repression of Black African, Coloured, and Asian South Africans for the benefit of the nation's minority white population. The economic legacy and social effects of apartheid continue to the present day.
Explanation: Broadly speaking, apartheid was delineated into petty apartheid, which entailed the segregation of public facilities and social events, and grand apartheid, which controled housing and employment opportunities by race. Prior to the 1940s, some aspects of apartheid had already unfolded in the form of minority rule by White South Africans and the socially enforced separation of Black South Africans from other races, which later extended to pass laws and land apportionment. Apartheid was adopted as a formal policy by the South African government after the election of the National Party (NP) at the 1948 general election.
