The overthrow of Haile Selassie in Ethiopia in 1974, and the independence of Angola and Mozambique in 1975, as well as Zimbabwe in 1980, seem to have strengthened the case for classifying African régimes on the basis of their ideology.
In a collection of mainly country-studies of socialism in sub-Saharan Africa edited by Carl Rosberg and Thomas Callaghy in 1978, various explanations were advanced about why the so-called ‘first wave’ of radicals failed to transform African societies successfully, and a common theme was the major rô played by ideology in differentiating ‘African’ from ‘scientific’ socialist régimes.1 In 1981 David and Marina Ottaway contrasted the ‘African socialism’ of Guinea, Zambia, and Tanzania with the ‘Afrocommunism’ of Angola, Mozambique, and Ethiopia, and contended that ideology was the best indicator of the clear differences that existed in both their institutions and policy choices.2 In 1982 Crawford Young placed African régimes in three ideological categories: ‘Populist socialist’, and ‘African capitalist’.3
