Apartheid in South Africa began in 1948 which was just after Carel's parents, Elza and Hennie Pretorius, were born. Afrikaaners took over the government and enforced apartheid policy. Carel's grandparents were very conservative and they were pro-apartheid. When Hennie Pretorius grew older he lived in Europe to get a better education. After this, he and Elza came to have more liberal beliefs. They became serious anti-apartheid activists when they returned to South Africa.
“It was very difficult because my parents were anti-apartheid activists."
-- Carel Pretorius
Carel's father was highly educated. He got a PHD at a very young age during his time in Europe, however he could not get any good positions in his field because of his political views. He was very anti-apartheid. While white men in South Africa had little difficulty finding opportunities due to apartheid, Hennie's active role fighting against it made it nearly impossible for him to get a job to make a living. He ended up working in an Independant Home Land, which was a territory that the National Party administration of South Africa set aside for black inhabitants of South Africa. It was one aspect of the apartheid policy.
Hennie, Carel's dad, and Wessel, Carel's brother, were sent to jail for protesting and fighting against apartheid and racism. The challenges that the Pretorius family faced were not easy to overcome, but Carel's family continued to be persistent, fighting apartheid and working for what they believed in.
“I still remember even though I was young, signs for “Whites Only” and “Natives Only”... on bathrooms, bus stops, drinking fountains. It was terrible."
-- Carel Pretorius
The area where the Pretorius family lived did not have very good education, so eventually Carel went to a boarding school in Bloemfontein, a very conservative city. The black people were typically working as servants and the white people had tons of privilege.
