The August 1983 overthrow of Major Jean-Baptiste Ouedraogo by Captain Thomas Sankara in Upper Volta (now Burkina Faso), the New Year's Eve abrupt termination in Nigeria of Black Africa's largest multi-party democracy, and the decision by the Guinean army in April 1984 to remove their party leaders after the death of President Sékou Touré, illustrate two of the most salient realities of contemporary African politics: (1) military coups d'état are the principal form of régime change, and (2) they can happen under any type of political system–a functioning democracy, a personalistic civilian dictatorship, or an already existing military junta.1
