The document discusses the exclusion of South Africa and Rhodesia from the Olympic Games due to apartheid and political pressures in the late 1960s and early 1970s. It highlights the role of the International Olympic Committee (IOC), African nations, and geopolitical changes influencing these decisions, particularly around the 1972 Munich Olympics.
