Apartheid was a legal racial separation system that ruled the Republic of South Africa from 1948 to 1993. Apartheid's mechanisms were in place before its creation, and South Africa is still dealing with these issues. Apartheid divided various races into different regions, and discrimination against people of color was not only acceptable, but also legal, with white people having full priority on housing, jobs, education, and political power. Even though South Africa was constantly chastised for the system, it wasn't until 1991 that the legal system of apartheid began to crumble, and it was finally brought down in 1993.
What is Apartheid?
Apartheid has been legally abolished, but whites and blacks continue to coexist in separate communities. There are still "black" and "white" neighborhoods, as well as "black" and "white" churches and restaurants. When the international media writes about Southern Africa, they almost always mention the country's "fading rainbow" and experiment in multi-ethnic democracy .
