Foreign military intervention has had a profound impact on post-colonial African history and politics. Interventions have destabilized borderlands, overthrown governments, and taken a devastating toll on populations. Emizet F. Kisangani and Jeffrey Pickering advance a new theoretical framework and combine quantitative, qualitative, and historical methods to shed fresh light on these important but understudied events. Their detailed analysis brings understanding to supportive and hostile interventions and to interventions by former colonial states, non-colonial foreign actors, and African countries. Kisangani and Pickering also analyse military incursions into ungoverned territories and lands engulfed in civil war. Showcasing a variety of examples from the Second Congo War to the Ethiopian-Eritrean conflict, the book offers a rich and accessible examination of military intervention on the continent.
