In Sub-Saharan Africa, the spread of democracy since the 1990s has been accompanied by the proliferation of bans on ethnic political parties. A majority of constitutions in the region explicitly prohibit political parties to organize on the basis of race, ethnicity, religion, region and other socio-cultural attributes. More than a hundred political parties have been dissolved, suspended or denied registration on these grounds. This book documents the experience with ethnic party bans in Africa, traces its origins, examines its record, and answers the question whether ethnic party bans are an effective and legitimate instrument in the prevention of ethnic conflict.This book was published as a special issue of Democratization.
