Which Olympics was the last time South Africa was allowed to compete due to apartheid?

The last Olympics that South Africa was allowed to compete due to apartheid was indeed in 1964. During this time, South Africa was still under a system of racial segregation that heavily influenced its participation in international sports. The International Olympic Committee (IOC) had already suspended South Africa from the Olympic Games from 1964 onwards due to growing tensions and international pressure concerning its apartheid policies. After its performance in 1964, South Africa was prohibited from participating in future Olympic events until they were reinstated for the 1992 Summer Olympics in Barcelona, well after the official end of apartheid. This significant historical context illuminates why 1964 marks the last participation for South Africa under the apartheid regime.
