On Nov. 11, 1965, the conservative white-minority government of Rhodesia declared its independence from Britain. The country resisted the demands of black Africans, and Prime Minister Ian Smith withstood British pressure, economic sanctions, and guerrilla attacks in his effort to uphold white supremacy. On March 1, 1970, Rhodesia formally proclaimed itself a republic. Heightened guerrilla war and a withdrawal of South African military aid in 1976 marked the beginning of the collapse of Smiths 11 years of resistance.

Black nationalist movements were led by Bishop Abel Muzorewa of the African National Congress and Ndabaningi Sithole, who were moderates, and guerrilla leaders Robert Mugabe of the Zimbabwe African National Union (ZANU) and Joshua Nkomo of the Zimbabwe African Peoples Union (ZAPU), who advocated revolution.

On March 3, 1978, Smith, Muzorewa, Sithole, and Chief Jeremiah Chirau signed an agreement to transfer power to the black majority by Dec. 31, 1978. They formed an executive council, with chairmanship rotating but with Smith retaining the title of prime minister. Blacks were named to each cabinet ministry, serving as coministers with the whites already holding these posts. African nations and rebel leaders immediately denounced the action, but Western governments were more reserved, although none granted recognition to the new regime.
