The end of apartheid in South Africa was a complex and significant historical process that unfolded over several decades. Apartheid, a system of institutionalized racial segregation and discrimination, was established by the National Party in 1948. The policies of apartheid aimed to enforce the supremacy of the white minority and systematically oppressed the majority black population, relegating them to inferior social, economic, and political status.

The resistance against apartheid gained momentum in the 1960s and 1970s, with various movements and leaders advocating for equality and justice. International pressure, in the form of economic sanctions and diplomatic isolation, also played a crucial role in pressuring the South African government to reconsider its policies.

One pivotal moment was the release of Nelson Mandela from prison in 1990 after 27 years of incarceration. Mandela's release signaled a turning point in the country's history, and negotiations began between the apartheid government and anti-apartheid activists, including Mandela and the African National Congress (ANC). These negotiations led to the dismantling of apartheid laws and the initiation of democratic reforms.

In 1994, South Africa held its first fully democratic elections, where people of all races were allowed to vote. Nelson Mandela emerged victorious, becoming the nation's first black president. His presidency marked a period of reconciliation and healing, as Mandela emphasized forgiveness and unity in overcoming the deep-rooted divisions caused by decades of apartheid.
