Alevism (/æˈlɛvɪzəm/; Turkish: Alevîlik or Turkish: Anadolu Alevîliği/Alevileri, also called Qizilbash,[1] or Shī‘ah Imāmī-Tasawwufī Ṭarīqah, or Shīʿah-ī Bāṭen’īyyah)[2] is a syncretic,[3] heterodox,[4] and local Islamic tradition,[5] whose adherents follow the mystical (bāṭenī)[2] teachings of Ali, the Twelve Imams and a descendant—the 13th century Alevi saint Haji Bektash Veli. Alevis are found primarily in Turkey among ethnic Turks and Kurds,[6] and make up between somewhere between 10 and 40% of Turkey's population,[7] the largest belief after Sunni Islam.[5]
