The impact of criminal prosecutions during intrastate conflict

The International Criminal Court's interventions have prompted debate about the wisdom of criminally prosecuting combatants while attempting to build peace in conflict-ridden societies. Previous research fails to distinguish between different types of trials. Using a large-N dataset of three types of criminal trials undertaken during internal conflict - domestic security trials of rebels, domestic human rights trials of state agents, and international war crimes trials of both - this article tests a theory of the compellent effect of criminal prosecution on conflict termination. We find that, even when accounting for endogeneity, rebel trials are associated with a higher probability of conflict termination, while trials of state agents are weakly associated with conflict persistence. We argue that the former compel the opposition to discontinue fighting, while the latter signal to rebels a lack of government resolve. We also find that the effect of international trials, which at times appear weakly associated with conflict termination, is endogenous to international intervention more generally.
