The movement aimed at dismantling the apartheid system in South Africa was the Anti-Apartheid Movement. It gained momentum in the mid-20th century, advocating against the institutionalized racial segregation and discrimination enforced by the apartheid regime from 1948 onward. Key figures like Nelson Mandela, Desmond Tutu, and Oliver Tambo played crucial roles in mobilizing national and international support. Nonviolent protests, strikes, and international sanctions were employed to challenge the oppressive system. The movement ultimately succeeded, leading to the dismantling of apartheid laws in the early 1990s, and the establishment of a multiracial democracy in South Africa with Nelson Mandela becoming its first black president.
