Why did congress impose economic sanctions in South Africa?

Congress imposed economic sanctions on South Africa primarily to protest the country's apartheid policies, which enforced racial segregation and discrimination against the non-white population. These sanctions aimed to pressure the South African government to dismantle apartheid and promote racial equality and human rights. The measures included trade restrictions and divestment from South African companies, reflecting a growing international consensus against apartheid in the 1980s. Ultimately, these actions contributed to the eventual end of the apartheid regime.
