Sustaining the Peace: Determinants of Civil War Recurrence

Over half of all civil wars that began and ended between 1944 and 1997 were followed by at least one if not more episodes of civil war. We present a model to explain which characteristics of a civil war and the post-war environment make civil war more or less likely to recur. We test this model with data on civil wars that began and ended between 1944 and 1997. Findings suggest that civil wars are less likely to recur following rebel victories and peace agreements supported by peacekeeping forces. Post-war economic development also reduces the probability of civil war recurrence, and the longer the peace can be sustained, the less likely civil war is to recur. These effects hold regardless of whether the previous war was ethnically based or not, and whether it was secessionist or revolutionary.
