Tambo

In 1960, when the apartheid state banned the African National Congress following the Sharpeville Massacre, Oliver Tambo was already abroad on ANC business. He had been sent ahead to build international support. He did not return to South Africa for thirty years. In those thirty years he built, from a sequence of offices in Dar es Salaam, Lusaka, and London, one of the most effective international solidarity campaigns in the history of human rights diplomacy — a campaign that isolated apartheid South Africa economically, diplomatically, and culturally, that secured arms embargoes and trade sanctions, that kept the imprisoned Nelson Mandela alive in the world's consciousness, and that ultimately created the conditions under which the apartheid regime was forced to negotiate its own end. He did this from exile, without an army, without a country, and without the international recognition of a head of state. He did it with legal training, extraordinary diplomatic skill, strategic patience, and a moral clarity about what he was fighting for that never wavered across three decades.

Oliver Reginald Tambo was born on October 27, 1917, in Nkantolo, a village in the Eastern Cape. His father was a subsistence farmer; his mother died when he was a child. He was educated at mission schools and showed exceptional academic promise, winning a scholarship to the University of Fort Hare — the only university in sub-Saharan Africa that admitted Black students and that educated many of the generation's liberation leaders, including Nelson Mandela, Robert Mugabe, Julius Nyerere, and Herbert Chitepo. At Fort Hare, Tambo studied mathematics and natural science. He and Mandela became close friends and co-founders of the ANC Youth League, a radical faction that pushed the parent organization toward mass mobilization and active confrontation with the apartheid state. He was expelled from Fort Hare for organizing a student protest, completed his degree by correspondence, and went on to study law at Witwatersrand.

In 1952, Tambo and Mandela opened South Africa's first Black law firm in Johannesburg — Mandela and Tambo, Attorneys — providing legal representation to Africans who had no access to the legal system. The firm was immediately busy and immediately harassed by the apartheid authorities. In 1956, both were among the 156 people charged with high treason in the Treason Trial, which lasted until 1961. Tambo was eventually not among those convicted. He left South Africa in January 1960 on ANC instruction, tasked with building international support networks. Three months later, the Sharpeville Massacre and the subsequent banning of the ANC transformed a temporary diplomatic mission into a three-decade exile.

Tambo became ANC President in 1967 following the incapacitation of Chief Albert Luthuli. His political strategy rested on three pillars: sustained armed resistance inside South Africa through Umkhonto we Sizwe (the ANC's military wing, whose operations he oversaw from Lusaka); mass internal mobilization through the trade unions and civic organizations that survived banning; and the international isolation of the apartheid regime through sustained diplomatic pressure on Western governments, corporations, and international sports bodies. On the international front he was spectacularly effective. By the mid-1980s, most Western European governments had imposed sanctions, major corporations were divesting, South Africa had been expelled from international sports, and the United States Congress had overridden Ronald Reagan's veto to pass the Comprehensive Anti-Apartheid Act of 1986. This was not accidental. It was the product of twenty-five years of Tambo's diplomatic work, conducted through embassies, solidarity organizations, trade unions, churches, university campuses, and international organizations across four continents.

Tambo suffered a severe stroke in 1989, which left him partially incapacitated. He returned to South Africa in December 1990, shortly after Nelson Mandela's release, to a hero's welcome. He was too ill to play an active role in the negotiations that ended apartheid but lived to see the ANC's unbanning and the beginning of the democratic transition he had worked thirty years to create. He died on April 24, 1993, a year before the first democratic election in which Black South Africans could vote. Nelson Mandela, in his autobiography, called him the greatest man he ever knew. The Oliver Tambo International Airport in Johannesburg — South Africa's largest — was named in his honor in 2006.

Tambo's legacy is inseparable from the question of how apartheid ended. The apartheid state was extraordinarily well armed, internationally supported until the 1980s by the United States and Britain, and domestically brutal. It did not collapse because of internal pressure alone. It collapsed because it became internationally untenable — economically, diplomatically, and morally — and this was substantially Tambo's achievement. The man who kept the ANC alive in exile, who kept Mandela's name in the world's consciousness through the darkest years, who built the international framework within which the apartheid state had nowhere left to hide, deserves recognition not just as a footnote to Mandela's story but as one of the great diplomatic strategists of the twentieth century.
