When apartheid was the official policy in South Africa, many sportspeople adopted the conscientious approach that they should not appear in competitive sports there. Some feel this was an effective contribution to the eventual demolition of the policy of apartheid, others feel that it may have prolonged and reinforced its worst effects. Many African nations boycotted the 1976 Summer Olympics in Montreal, as a result of then New Zealand Prime Minister Rob Muldoon allowing the All Blacks to tour South Africa. The issue would later come to a head during the 1981 Springbok Tour.Douglas Booth, "Hitting apartheid for six? The politics of the South African sports boycott."
