The appearance of revolutions and revolutionary movements in developing countries is a result of political as well as social and cultural developments and dynamics. More specifically, as discussed in previous chapters, the particular characteristics of Third World states, the larger consequences of social change, and the features inherent in political cultures combine to give rise to conditions conducive to the outbreak of revolutions. Nevertheless, despite the widespread prevalence of such conditions throughout the developing world, revolutions are rather rare historical occurrences. Why, it is thus important to ask, have revolutions not taken place with greater frequency given the existence of their social and political preconditions? Moreover, exactly how and what social and political dynamics lead to revolutions and at which specific junctures?
