International isolation and the Anti-Apartheid Movement
The International Response to Apartheid
Resistance to apartheid was not confined to South Africa. From the early 1960s, an international movement grew to isolate the apartheid regime through boycotts, sanctions and public protest. The Anti-Apartheid Movement (AAM) was founded in Britain in 1959, initially as a small activist group. By the 1980s it had become a mass movement with significant political influence.
Trevor Huddleston, an Anglican priest who had lived and worked in Sophiatown (a vibrant mixed-race area of Johannesburg that was demolished under the Group Areas Act), was a founding figure of the British AAM. His memoir Naught for Your Comfort (1956) had introduced many British readers to the reality of apartheid.
Three major forms of international pressure combined: sports isolation (South Africa excluded from the Olympics from 1964; Gleneagles Agreement 1977 on Commonwealth sports), economic sanctions (US Comprehensive Anti-Apartheid Act 1986; Chase Manhattan refused to roll over loans 1985) and diplomatic isolation (left the Commonwealth 1961; UN mandatory arms embargo 1977).
Sports Isolation
Sport was among the most publicly visible fronts of the isolation campaign. South Africa was excluded from the 1964 Tokyo Olympics and banned from all subsequent Games until 1992. In 1970 South Africa was shut out of international cricket when its tour of England was called off. The Gleneagles Agreement (1977) committed Commonwealth governments to discouraging sporting contact with South Africa. When rebel cricket and rugby tours were organised in defiance of the boycott, they provoked significant protests.
For many white South Africans, the sports boycott was among the most psychologically damaging forms of isolation — South Africa had strong sporting traditions and international competition mattered to white identity. Apartheid supporters argued the boycott was “politics in sport”; anti-apartheid campaigners replied that apartheid itself had already politicised sport by enforcing racial selection policies.
Economic pressure grew through the 1980s. In 1985, the Chase Manhattan Bank refused to roll over South Africa’s short-term loans — a dramatic signal that international financial confidence in the regime was collapsing. Other banks followed. The South African government declared a debt moratorium in September 1985.
In 1986, the United States Congress passed the Comprehensive Anti-Apartheid Act, imposing sweeping economic sanctions. President Reagan vetoed the bill on “constructive engagement” grounds, but Congress overrode his veto — a rare and significant act. Universities, pension funds and corporations across the US and Europe were pressured by campaign groups to divest from companies doing business in South Africa.
Oliver Tambo and Desmond Tutu
Oliver Tambo’s work in exile was central to the international campaign. He lobbied the United Nations, the Organisation of African Unity and sympathetic governments. The ANC under his leadership maintained MK training camps and built alliances with the Soviet Union, Sweden and other states that provided financial and logistical support.
Desmond Tutu, Archbishop of Cape Town from 1986 and Nobel Peace Prize winner (1984), was one of the most prominent internal voices calling for sanctions. He argued that economic pressure was the only non-violent alternative to escalating violence inside South Africa.
Reagan and Thatcher both opposed comprehensive sanctions, arguing that “constructive engagement” — maintaining economic ties — would encourage reform more effectively. Critics (including Tutu and the ANC) argued this was a justification for protecting Western economic interests and that it gave the regime legitimacy it did not deserve.
South Africa had left the Commonwealth in 1961, withdrawing its application to stay in as a republic once other members attacked apartheid. In 1977, following Biko’s death and the Soweto uprising, the United Nations Security Council passed Resolution 418 — a mandatory arms embargo that required all member states to stop selling weapons to South Africa. This was the UN’s most significant direct action against apartheid. South Africa responded by developing its own arms industry (Armscor) and seeking covert supplies, but the embargo nonetheless damaged its military capacity.
Corporate Disinvestment and the Campaign in Universities
Beyond government sanctions, the disinvestment campaign targeted private companies. Barclays Bank — which had a major presence in South Africa through its subsidiary Barclays National Bank — faced sustained protests in British universities during the late 1970s and early 1980s. Students union campaigns against Barclays culminated in the bank selling its South African subsidiary in 1986. Shell, IBM and dozens of other corporations came under similar pressure from shareholders and consumers to divest from South Africa. By 1987, over 200 American companies had withdrawn investments.
The Commonwealth Eminent Persons Group (EPG) visited South Africa in 1986 to explore whether conditions for negotiation existed. The EPG recommended comprehensive Commonwealth sanctions after the South African government launched military raids into Zambia, Zimbabwe and Botswana — frontline states supporting the ANC — during the very week the EPG was visiting. Only Thatcher’s Britain blocked full Commonwealth sanctions, but the political isolation was already overwhelming.
