Abstract
We consider whether the fragmentation of combatants during civil war has downstream effects on the durability of peace following civil wars. We contend that the splintering of combatant groups, a primary manifestation of rebel group fragmentation, produces potential spoiler groups that are neither incidental nor unimportant in the process of civil war resolution. Making connections to the spoiling and credible commitment literatures, we hypothesize that rebel splintering hastens the recurrence of civil wars. Using event history modeling and propensity score matching to analyze two different civil war datasets, we examine whether the occurrence of fragmentation during a civil war influences the length of peace after the civil war. The empirical analysis of fragmentation events during civil wars since World War II offers support for the hypothesis that splintering decreases the duration of post-civil war peace. The results suggest the need to pay closer attention to the dynamics of fragmentation, and particularly how these dynamics lead to future consequences – even when those consequences take place after the war has concluded. For example, governments that attempt to splinter groups or to use existing fragmentations within rebel groups to end a civil war may encourage the unintended consequence of shorter peace duration.
