Across Africa in the post-1956 era, the aspirations of African nationalists to secure power were boosted and quickly realized by the British, French and Belgian hasty retreat from empire. The Portuguese, Southern Rhodesian and South African governments, however, stood firm and would be challenged by their African nationalists.

In the case of Rhodesia, the Zimbabwe African People's Union (ZAPU), led by Joshua Nkomo, took this step in 1962 after their effort to foment rebellion in Rhodesia's urban areas in 1961-62 had been frustrated by police action and stiffened security legislation.
