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.

和平协议后前叛乱分子政党的出现为政治重新整合创造了一个工具，这反过来又对战后和平和民主的巩固产生了积极影响。然而，这些政党中的许多政党往往会分裂和消失，从而增加了政治暴力新一轮循环的风险。在战争时期，凝聚力在维护武装组织成员之间的纽带方面起着关键作用。它使他们能够在面对具有挑战性的条件下有效地执行任务，并继续成为冲突后过渡期间的关键因素。通过对哥伦比亚前 FARC 游击队（现在是新成立的合法政党的一部分）进行定量分析，我们测试了意识形态、组织动力或个人观念和动机是否有助于解释他们的凝聚力水平。我们的结果表明，即使所有维度的总和都达到观察到的凝聚力水平，对内部民主和包容性的看法也是最相关的。我们认为，在战后对前叛乱分子的组织重组工作提供援助将有助于降低叛乱党崩溃的负面影响的风险。
