World War II brought an end to the race, but it was revived in 1960 as part of the Formula One circuit, entering the World Championship calendar two years later. It was a popular F1 event, but the Grand Prix was suspended right after the controversial 1985 race, due to the nation's policy of apartheid. Following the end of apartheid in 1991, two further races were held in 1992 and the last time, 1993.
