Islam in Turkey

Islam is the predominant religion in Turkey, with about 90% of Muslims belonging to the Sunni branch of Islam and predominantly following the Hanafi fiqh. The Shia sects make up about 10% of the population, with most of them being adherents of the Alevi faith, which is considered by most of its followers to be a form of Shia Islam. However, a minority considers it to have different origins. The Bektashi community is a small Sufi order of Islam that is closely related to Alevism and is indigenous to Turkey, but it also has many followers in the Balkan peninsula. Other sects such as Alawite, observed by some ethnic Arabs in southern provinces, and Jafari, the traditional sect of ethnic Azerbaijanis, also have significant populations in Turkey.
