This article considers initiatives to reform religious education after violent identity-based conflicts in Lebanon, Northern Ireland and Macedonia. The Taif Agreement, the Belfast Agreement and the Ohrid Agreement mapped extensive education reforms and established consociational power-sharing in the three jurisdictions, altering state identity and inter-communal hierarchies. The existing literature generates two hypotheses on the political function of religious education after violent conflicts: (1) religious education tends to entrench existing ethnic, national and political cleavages or (2) religious education helps further mutual knowledge, integration and social cohesion after violent conflicts. This comparative research employs original interviews and documents to evaluate initiatives to reform religious education (as a curricular subject) in post-conflict Lebanon, Northern Ireland and Macedonia. It suggests that the first hypothesis reflects more accurately the political function of education: religious education helps entrench existing cleavages in these deeply divided societies, but this does not necessarily hamper short-term peace and political stability.
