When Civil Wars Recur: Conditions for Durable Peace after Civil Wars

We argue that the duration of the peace after civil wars is mainly a function of the extent to which the outcome of the previous civil war preserved a condition of multiple sovereignty and the extent to which the post-civil war environment creates incentives for dissident groups to resort to violence rather than sustain the peace. Hazard models suggest that the outcome of the previous conflict does affect the duration of the peace, and this effect varies across time. The introduction of peacekeeping forces has a substantial positive effect on peace duration. We also find evidence of a curvilinear relationship between ethnic fractionalization and post-civil war peace duration. Based on these results, we conclude with recommendations for how peace can be maintained after a civil war.
