Childhood, Family Background, and Education
Oliver Tambo was born on 27 October 1917 in the village of Nkantolo in Bizana, Eastern Pondoland, now part of the Eastern Cape province.
He was born into a family of subsistence farmers, and his father, Mzimeni Tambo, was also an assistant salesperson at a local trading store. Mzimeni had four wives and ten children, all of whom were literate—a rarity at the time. Oliver’s mother, Julia, was Mzimeni’s third wife and played a significant role in his early upbringing.
Oliver Tambo’s Early Activism
Tambo excelled academically and graduated from high school in 1938 as one of the top students. He was admitted to the University of Fort Hare, one of the only institutions in South Africa that provided higher education to Black students. However, his academic journey was disrupted in 1940 when he, along with Nelson Mandela and other students, was expelled for participating in a student strike protesting against the university administration’s policies.
Following his expulsion, Tambo returned to Johannesburg and began teaching science and mathematics at his former high school. His early exposure to educational inequality and racial injustice fueled his commitment to activism.

Political Beginnings and the ANC Youth League
In 1944, Tambo, alongside Nelson Mandela and Walter Sisulu, founded the African National Congress Youth League (ANCYL). The Youth League sought to revitalize the ANC by introducing more radical tactics aimed at dismantling apartheid. Tambo became its first National Secretary and later joined the National Executive in 1948.
Dissatisfied with the ANC’s traditional methods of petitions and peaceful demonstrations, the Youth League introduced the “Program of Action,” advocating for boycotts, strikes, civil disobedience, and non-collaboration. This shift marked a turning point in South Africa’s liberation struggle, leading to increased mass mobilization against apartheid.
Ascending the Ranks of the ANC
In 1955, Tambo was appointed Secretary-General of the ANC after Walter Sisulu was banned by the apartheid government under the Suppression of Communism Act. Three years later, he became the ANC’s Deputy President. His role in the ANC continued to grow, but in 1959, he was served with a five-year banning order, restricting his political activities within South Africa.
Faced with increasing state repression, the ANC leadership sent Tambo into exile in 1960 to mobilize international opposition to apartheid. He settled in Muswell Hill, London, with his family, where he lived until 1990. His wife, Adelaide, remained active in supporting ANC members within South Africa. Despite the emotional toll of separation, Tambo continued his work abroad, ensuring that the world remained aware of the atrocities occurring in South Africa.
Leadership in Exile
Following the death of Chief Albert Luthuli in 1967, Tambo became the Acting President of the ANC. During his tenure, he played a vital role in uniting the fragmented resistance movement and strengthening international alliances.
Tambo traveled extensively, meeting with world leaders and securing support for the anti-apartheid cause. His diplomatic skills led to strong ties between the ANC and socialist governments, including the Soviet Union, Cuba, and various African states. These relationships provided the ANC with financial resources, military training, and weapons.
Under Tambo’s leadership, the ANC intensified its armed struggle against the apartheid government. He played a key role in directing guerrilla operations carried out by the ANC’s military wing, Umkhonto we Sizwe (MK). In a 1985 interview, he acknowledged that civilians might be affected by the ANC’s armed resistance, reflecting the complexities of waging a liberation struggle against a heavily militarized regime.
The Church Street Bombing and the Truth and Reconciliation Commission
Between 1978 and 1979, Tambo authorized special operations units to carry out attacks against strategic targets in South Africa.
One of the most controversial incidents was the 1983 Church Street bombing, which resulted in 19 deaths and nearly 200 injuries.
The ANC justified the attack as a response to the South African Defence Force’s (SADF) cross-border raids, but the Truth and Reconciliation Commission (TRC) later investigated the event, leading to amnesty applications from those involved.
Return to South Africa and the Path to Democracy
Tambo returned to South Africa on 13 December 1990, following the unbanning of the ANC. His return was met with widespread support, even from former political rivals. However, his health had deteriorated due to a stroke he suffered in 1989, limiting his capacity to lead the ANC’s transition into a legal political organization.
In 1991, at the ANC’s 48th National Conference, Nelson Mandela was elected President of the ANC, while Tambo was honored with a newly created position of National Chairman in recognition of his contributions. His leadership had laid the groundwork for the democratic transition that would follow in the coming years.
Honors and Legacy
Oliver Tambo’s contributions have been honored through various recognitions. In 2006, Johannesburg International Airport was renamed O.R. Tambo International Airport in his honor. Additionally, statues, memorials, and parks have been dedicated to him, both in South Africa and abroad.
His house in Muswell Hill, London, was purchased by the South African government in 2010 and is now a historical monument. Similarly, the ANC safe house in Lusaka, Zambia, where he spent much of his time in exile, has been declared a national monument.
Tambo was instrumental in fostering international solidarity against apartheid. In 1977, he signed the first solidarity agreement between the ANC and an Italian municipality, Reggio Emilia. This partnership led to numerous acts of support from Italy, including the dispatch of humanitarian aid and the minting of the prestigious Isitwalandwe Medals.
Oliver Tambo’s life was one of unwavering dedication to justice, equality, and the liberation of South Africa.
Personal Life and Death
Tambo was a devout Anglican and a devoted family man. Despite the hardships of exile, his wife Adelaide played an integral role in supporting both him and the ANC’s cause.
After suffering complications from his stroke, Tambo passed away on 24 April 1993, at the age of 75. His death occurred just a year before South Africa’s first democratic elections. Nelson Mandela, Thabo Mbeki, Walter Sisulu, and many other prominent leaders attended his funeral. He was laid to rest in Benoni, Gauteng.
