Name the organization that led the fight against Apartheid in South Africa.

The African National Congress (ANC) was the principal organization that led the fight against Apartheid in South Africa. Established in 1912, the ANC played a crucial role in resisting racial oppression and advocating for the rights of non-white South Africans. Throughout the years, the ANC organized protests, strikes, and other forms of activism aimed at dismantling the Apartheid system, which enforced racial segregation and discrimination.

Under the leadership of figures such as Nelson Mandela, the ANC garnered both national and international support, effectively mobilizing opposition to the Apartheid regime. The organization's persistent struggle included key events like the Defiance Campaign in the 1950s and the Soweto Uprising in 1976, which drew global attention to the injustices of Apartheid.

While other organizations, such as the South African Communist Party, the Pan Africanist Congress, and the South African Democratic Movement, also contributed to the resistance against Apartheid, the ANC is most widely recognized for its central leadership role and eventually played a significant part in the negotiations that led to the end of Apartheid and the establishment of a democratic South Africa in the early 1990s.
