Sectarianism refers to division and conflict arising from differences in religious or political beliefs, often within the same broader faith or ideology. It typically manifests in hostility between groups, leading to discrimination, violence, or social fragmentation. For example, in the context of Islam, sectarianism can occur between Sunni and Shia communities, each holding distinct interpretations and practices. This phenomenon can also extend to other belief systems, such as Christianity, where divisions may arise between Catholics and Protestants. Sectarianism can hinder social cohesion and contribute to ongoing cycles of conflict, making it a significant issue in many regions around the world.
