Religion and History in Comoros

The Union of the Comoros is constitutionally Sunni Muslim of the Shafi'i school, a religious identity the constitution ties directly to national belonging by defining the Comorian people's principles and rules of worship and social life as drawn from Sunni Islam. Comorian Islam reflects the archipelago's position astride Swahili coast, Arab, Persian, Malagasy and French colonial trade and migration routes, blending Sufi brotherhood practice, notably the Shadhiliyya order, with older East African and Malagasy customs around ancestor veneration and spirit possession still observed alongside orthodox practice in some communities.

The islands' modern political geography carries its own religious and colonial history. Comoros' fourth member island by geography, Mayotte, voted to remain French rather than join Comorian independence in 1975 and is today administered separately as a French overseas department, a division the Comorian state continues to dispute. Mayotte's own religious composition has diverged from the rest of the archipelago in the decades since, shaped by its distinct constitutional relationship with France rather than with the independent Comorian union.
