Harry Mwaanga Nkumbula (1916–1983) was a Zambian nationalist leader involved in the movement for the independence of Northern Rhodesia, as Zambia was known until the end of British rule in 1964. He was born in the village of Maala in the Namwala district of Zambia's southern province. He was the youngest of three children and the only son.
Nkumbula received his early formal education at Methodist mission schools and in 1934 completed Standard VI at the Kafue Training Institute. He then taught in Namwala District for several years.
In 1938 Nkumbula joined the Northern Rhodesian government's teaching service and later worked in Kitwe and Mufulira on the Copperbelt. During World War II he became involved in African nationalist politics, like many other educated Africans of the day. For example, he held the position of Secretary of the Mufulira Welfare Association and co-founded the Kitwe African Society.
In 1946, from Chalimbana Teacher Training School, Nkumbula went to Kampala's Makerere University College in Uganda. This was made possible by the support of Sir Stewart Gore-Browne, a pro-black British settler politician. From Makerere, Nkumbula went on to study for and received a diploma from the Institute of Education, University of London. In London, Nkumbula had the opportunity to meet other African nationalists who were galvanized after attending the 1945 Pan-African Congress in Manchester, England. In 1949 he worked with Nyasaland's Hastings Kamuzu Banda in drafting a document that expressed African opposition to the proposed white-dominated Central African Federation. This collaboration prepared the two men for their subsequent struggles with the colonialists in their home countries. After his diploma, Nkumbula enrolled to study economics at the London School of Economics but he failed his examinations and returned to Northern Rhodesia without a degree early in 1950.
As a militant, articulate and uncompromising opponent of the Federation, Nkumbula was elected president of the Northern Rhodesian African Congress in 1951. The party was soon renamed the African National Congress (ANC). In 1953, Kenneth Kaunda became secretary general of the ANC. When Nkumbula called a national strike - disguised as a "national day of prayer" — in opposition to the Federation, the African population did not respond. This was due to the opposition of the president of the African Mineworkers' Union, Lawrence Katilungu, who campaigned against the strike on the Copperbelt. In October 1953, the white colonial settlers formed the Federation of Rhodesia and Nyasaland, ignoring the black African majority's opposition. In the early months of 1954, Nkumbula and Kaunda organised a partially successful boycott of European-owned butcheries in Lusaka. However, Nkumbula, Kaunda and the ANC found it difficult to mobilize their people against the Federation.
