Why South Africa attained independence in 1994?

South Africa attained independence in 1994 primarily due to the end of apartheid, a system of institutionalized racial segregation and discrimination that had been in place since 1948. The internal resistance, led by figures such as Nelson Mandela and organizations like the African National Congress (ANC), combined with international pressure and sanctions against the apartheid regime, created an environment where negotiations for a democratic transition became possible. The unbanning of the ANC and other liberation movements in the early 1990s, coupled with a negotiated settlement, culminated in the first multiracial elections in April 1994, marking the official end of apartheid and the establishment of a democratic South Africa.
