Alevi means "follower of Ali". Alevis are the first minority in Turkey, representing 20% of the population. They are also located to a lesser extent in Bulgaria, Cyprus, Greece, the Caucasus and Iran.
Haçi Bektas Veli lived in the XIIIth century AD and settled down near Cappadocia. Sultan Sahkulu was his companion and together converted many Anatolian people to Islam and their brotherhood.
