ABSTRACT
During the 1990s the number of African states allowing multiparty elections increased dramatically. Paradoxically, this has been accompanied in the majority of countries by legal bans on ethnic and other particularistic parties. The main official reason has been the aim of preventing the politicization of ethnicity as this is feared to lead to ethnic conflict and political instability. Despite the resurgent interest in institutional engineering, this phenomenon has received little scholarly attention. This contribution outlines the main research questions and preliminary answers of a collaborative research project which combines large and small N comparisons and case studies. Bans are relatively rarely enforced and the decision actually to ban parties is best explained by the interaction of an experience of ethnic violence in the past and hybrid regimes using these measures to restrict political party competition. Positive effects on democracy and conflict management seem generally limited and are context dependent.
