The involvement of religious dimensions in armed conflict reduces the space for resolution and threatens the durability of peace. Yet, there are empirical cases showing that it is possible to address the challenges posed by religious dimensions. There are various avenues to secure durable peace for conflicts involving religious dimensions. Recent studies have focused on the usage of politico-religious solutions. Their findings are however limited to a series of case studies and still have multiple unknowns. This thesis aims to contribute to this body of research with the research question: How do politico-religious arrangements impact peace durability for intrastate armed conflicts involving religious dimensions? Building on previous research on the termination of civil wars and the resolution mechanisms for religious conflicts, this thesis develops a theoretical argument proposing that the provision of politico-religious solutions increases the likelihood of peace duration. A large-N analysis of 107 settlements from 1975 to 2018 related to 30 dyadic conflicts with religious dimensions, shows that there insufficient statistical evidence to support the proposed relationship. The findings question the generalisability of previous research and propose new avenues to further research the applicability of politico-religious solutions.
