Volume three concerns political action on the margins of conventional political participation in a democracy: extremist, protest, and social movements. This theme covers a huge spectrum, ranging from pro-democracy movements in authoritarian regimes to anti-democratic extremist. The volume is organised in four sections: first, a theoretical paper linking the social movements literature to the literature on democratization; second, a series of comparative studies; third, essays on the United States and western Europe; and finally, a set of studies of successful or failed democratic transition in Yugoslavia, South Africa and the Philippines. The first section presents an ambitious synthesis of social movement theories with the ‘political interactionist’ theories of democratization associated with Guillermo O'Donnell, Philippe Schmitter, Adam Przeworski and others. The second section contains comparative studies, examining whether recent right-wing extremist voting in western Europe represents a real shift to the right. Two dimensions of nationalism in eastern Europe are examined and another chapter looks at two contextual factors affecting political protest in western democracies: mobilization by collective organizations and national political and socioeconomic conditions. Finally Karl-Dieter Opp examines the prospective role of political protest in the European unification process. Four papers pursue the analysis of contemporary far right in France, Germany and Austria. What are the characteristics of French National Front voters? Focus is also placed on right-wing violence in unified Germany and racism and anti-semitism in Austria. Two potential threats to democracy are studied: Basque terrorism and nazism in interwar Germany. Finally in this, there is an examination of the rise to power of the Nazy Party in Germany.
