Factors responsible for the democratic trend include the legitimacy dilemmas of authoritarian regimes; economic and social development; the changed role of the Catholic Church; the impact of the United States, the European Community, and the Soviet Union; and the ""snowballing"" phenomenon: change in one country stimulating change in others. Five key elite groups within and outside the nondemocratic regime played roles in shaping the various ways democratization occurred. Compromise was key to all democratizations, and elections and nonviolent tactics also were central. New democracies must deal with the ""torturer problem"" and the ""praetorian problem"" and attempt to develop democratic values and processes. Disillusionment with democracy, Huntington argues, is necessary to consolidating democracy. He concludes the book with an analysis of the political, economic, and cultural factors that will decide whether or not the third wave continues.

Several ""Guidelines for Democratizers"" offer specific, practical suggestions for initiating and carrying out reform. Huntington's emphasis on practical application makes this book a valuable tool for anyone engaged in the democratization process. At this volatile time in history, Huntington's assessment of the processes of democratization is indispensable to understanding the future of democracy in the world.
