The Defiance Campaign against Unjust Laws was presented by the African National Congress (ANC) at a conference held in Bloemfontein, South Africa in December 1951. The Campaign had roots in events leading up the conference. The demonstrations, taking place in 1952, were the first "large-scale, multi-racial political mobilization against apartheid laws under a common leadership."

The African National Congress (ANC) is a political party in South Africa. It originated as a liberation movement known for its opposition to apartheid and has governed the country since 1994, when the first post-apartheid election resulted in Nelson Mandela being elected as President of South Africa. Cyril Ramaphosa, the incumbent national President, has served as President of the ANC since 18 December 2017.
