Abstract
In Northern Nigeria, where ethno-religious tensions have led to recurrent violence and societal fragmentation, faith-based leadership plays a pivotal role in shaping peace or perpetuating conflict. This paper examines the influence of religious leaders in fostering interreligious harmony and preventing violence across Muslim and Christian communities in the region. Anchored in peacebuilding theory and the ethics of interfaith dialogue, the study investigates how faith leaders mediate disputes, counter extremist narratives, and promote coexistence in deeply divided societies. Through qualitative methods, including interviews with clerics, community stakeholders, and interfaith organizations, the study uncovers religious authority's transformative potential and limitations in volatile contexts. Findings reveal that where religious leaders actively engage in inclusive dialogue, advocate for tolerance, and collaborate across faith lines, significant reductions in community-level tensions occur. However, challenges such as politicization of religion, doctrinal rigidity, and lack of institutional support often hinder broader impact. The study concludes that faith-based leadership, when mobilized strategically and ethically, is a powerful catalyst for sustainable peace and mutual understanding. It recommends a multi-level approach to peacebuilding that strengthens interfaith networks, empowers grassroots religious actors, and integrates spiritual leadership into national conflict prevention frameworks.
