In a recent article in the International Organization, Manuel Vogt, Lecturer in International Security at the Department of Political Science, explores why ethnic movements are more likely to turn violent in some multi-ethnic countries than in others. He finds that colonial legacies still have a profound impact on civil conflict risk in multi-ethnic states today. Internal colonialism in settler states is not only associated with high inter-group inequality but also with significantly lower levels of intergroup violence than those found in other multi-ethnic countries. In contrast, ethnic mobilization in the decolonized states and other segmented multi-ethnic societies is more likely to trigger violent conflict.
