Who Wins, Who Loses, Who Negotiates Peace in Civil Wars: Does Regime Type Matter?

Previous research has shown that the outcome of a civil war is related to conflict duration: military victory by either the government or the rebels occurs early if it occurs at all, and the longer a civil war lasts, the more likely it is to end in a negotiated settlement. The models of civil war duration and outcome that have produced these findings are built on characteristics of the civil war and less on attributes of the state itself, other than where the state lies on the Polity autocracy-democracy scale. We propose that how civil wars end varies not only between democracies and authoritarian regimes but among the different authoritarian regime types identified by Geddes, Wright, and Franz. The distinguishing attributes of these regime types-democracy, one-party, personalist, military, monarchical-should lead to different likelihood in defeating a rebel movement, being defeated by a rebel movement, and negotiating a peace agreement with a rebel movement. Results from a series of competing-risk models using the Uppsala-Peace Research Institute Oslo Armed Conflict Dataset demonstrate support for our claim that how civil wars end is partly a function of the characteristics of the regime.
