The Alevis are a religious community on the periphery of Shia Islam. The name “Alevi” means “Adherents of ʿAli,” alluding to Muhammad’s son-in-law and cousin ʿAli ibn Abi Talib, who enjoys extraordinary veneration among Alevis. Alevism was developed in Central Anatolia during the 13th century by itinerant Muslim mystics. It includes elements of pre-Islamic Turkish shamanism and aspects of mainstream Shia Islam, which influenced it through cultural contacts with Safavid Iran. Alevism never was a unified and homogeneous community but has always had a variety of sub-groups. For centuries Alevis practiced their rites in secret, which created suspicion and rumor among Sunnite Muslims. Today’s Alevis still have to struggle with this distrust, and are often regarded as heretics by the Sunnites. The designation “Alevi” came into use in the early 20th century as a collective term for a number of religious groups such as Bektaşi, Tahtacı, and Abdal, and today is used instead of the former, pejorative term Kızılbaş (“Red-Heads”). The Alevis are the largest religious minority group in the Republic of Turkey, where their estimated number is around 15 million. Large Alevi groups also reside in the Balkan states as well as in Central and Western Europe, particularly Germany and Austria. Roughly two-thirds of the Alevis are Turkish speakers. The other third speak Kurdish and Zazaki. In the 1980s, the community underwent the so-called “Alevi revival,” a process of exposure and openness that can be partly explained as a reaction against the re-Islamization of Turkish society. Today Alevis perform their rites and express their beliefs openly. Although they share certain features with them, the Alevis should not be confused with the Alawis (Nusayris), who live in southern Turkey and Syria and who are all Arabic speakers.
