The emergence of ex-rebels’ political parties after peace accords creates a vehicle for political reintegration, which in turn has positive effects on peace and democracy consolidation after war. However, many of these parties tend to break apart and disappear, elevating the risk of renewed cycles of political violence. In times of war, cohesion plays a pivotal role in maintaining the bonds among members of armed organizations. It empowers them to perform effectively even in the face of challenging conditions and continues to be a critical factor during postconflict transitions. By means of a quantitative analysis of former FARC guerrillas in Colombia, now part of a newly founded legal political party, we test whether ideology, organizational dynamics, or individual perceptions and motivations help to explain their levels of cohesion. Our results show that even if all dimensions add up to the observed cohesion levels, perceptions of internal democracy, and inclusion, are the most relevant. We argue that assistance to former rebels in their organizational reengineering efforts after war will help to reduce the risk of the negative effects of rebel party collapse.

Civilian confidence in domestic institutions, particularly in the security sector, is important for stability and state consolidation in post-conflict countries, where third-party peacekeepers have helped maintain peace and security after a conflict. While other scholars have suggested that a strong security sector is necessary for mitigating the credible commitment problem, this article provides two alternative criteria for assessing security sector reforms’ effect on confidence in the security sector: restraint and inclusiveness. Female ratio balancing in the security sector meets these two criteria, suggesting that it has the potential to help enhance confidence in the security sector and thereby create the right conditions for the peacekeeping transition. The argument is tested using original surveys conducted in post-conflict, ex-combatant communities in Liberia. The expectations received empirical support. The findings indicate that restraining and inclusive reforms could improve trust in the state’s security sector. They also demonstrate the importance of considering gender in theories related to post-conflict peace building and international relations more broadly.
