Definition
Religious conflict is strife rooted in differences of faith, encompassing persecution of minorities, struggles over religious authority, and wars fought partly or wholly in the name of religion. It occurs both between distinct religions and between rival branches of a single faith.
History offers many examples, including the Crusades, the Reconquista, the European Wars of Religion, and the schisms within Christianity and Islam.
Why it matters
How it works
Religion can become a source of conflict when belief is tied to identity, political authority, or claims to land. Rulers have used religious difference to mobilize populations and justify expansion, while genuine theological disagreement has also driven schism and persecution. Yet religious difference does not always produce conflict; many societies, such as medieval Iberia under Muslim rule, sustained long periods of coexistence. Conflict tends to intensify when political leaders find advantage in framing rivals as religious enemies.
