Pan-Islamism is a political movement advocating the unity of Muslims under one Islamic state – often a Caliphate – or an international organization with Islamic principles. As a form of religious nationalism, Pan-Islamism differentiates itself from other pan-nationalistic ideologies, for example Pan-Arabism, by excluding culture and ethnicity as primary factors towards unification.
