Several independent sectors of South African society opposed apartheid through various means, including social movements, passive resistance, and guerrilla warfare. Mass action against the ruling National Party (NP) government, coupled with South Africa's growing international isolation and economic sanctions, were instrumental in leading to negotiations to end apartheid, which began formally in 1990 and ended with South Africa's first multiracial elections under a universal franchise in 1994.
Apartheid was adopted as a formal South African government policy by the NP following their victory in the 1948 general election. From the early 1950s, the African National Congress (ANC) initiated its Defiance Campaign of passive resistance. Subsequent civil disobedience protests targeted curfews, pass laws, and "petty apartheid" segregation in public facilities. Some anti-apartheid demonstrations resulted in widespread rioting in Port Elizabeth and East London in 1952, but organised destruction of property was not deliberately employed until 1959. That year, anger over pass laws and environmental regulations perceived as unjust by black farmers resulted in a series of arsons targeting sugarcane plantations. Organisations such as the ANC, the South African Communist Party, and the Pan Africanist Congress (PAC) remained preoccupied with organising student strikes and work boycotts between 1959 and 1960. Following the Sharpeville massacre, some anti-apartheid movements, including the ANC and PAC, began a shift in tactics from peaceful non-cooperation to the formation of armed resistance wings.
