Alevi and Bektashi beliefs are presumed to have their origins in Central Asian Turkmen culture. However, they are likely to have absorbed Christian beliefs when Byzantine peasantry adopted the Alevi faith during the Turkic conquest of Anatolia during the tenth and eleventh centuries, and Iranian pre-Islamic ideas, since Kizilbash beliefs derived from the founders of the Iranian Safavid dynasty.
Isolated within what became Sunni Ottoman territory, Alevis have long been reviled. Many belonging to the majority have viewed Alevis as non-Muslims and questioned their loyalties, as well as targeted them with unfounded and scurrilous libels. To avoid persecution, Alevis practice taqiyya (dissimulation). Many Alevis celebrate the life of the sixteenth-century saint, Pir Sultan Abdal, a symbol for community cooperation and opposition to injustice.
Until relatively recently Alevis survived by living in remote areas. Hopes of faring better under a secular republic failed to take account of popular prejudice. With conscription and the drift towards towns in search of work, Alevis, especially Kurds, have increasingly been exposed to Sunni prejudice and animosity. This was often reflected at an official level, with policies such as the lack of legal status of Alevi cemevis (places of gathering and worship) and the widespread prohibition of their construction – a ban that remained in place until 2015.
However, there has also been a change in what Alevism signifies. Traditional Alevism, based upon village and rural life, broke down in the context of urbanization. In its place Alevism strongly identified with the political left. The Sunni Islamic revival of the 1980s has provoked a reaction among Alevis. The revivalist process has been an ethno-political movement rather than a strictly religious one, with a spate of publications in Türkiye concerning Alevi religion and history. Initiation into the esoteric aspects of the religion is dying out, but an Alevi cultural renaissance is undoubtedly taking place.
Tension between Sunni rightists and Alevi leftists grew from the 1970s. In part it was the migrant drift of Alevis from mountainous or unproductive land to seek work in predominantly Sunni towns which was a major catalyst in Sunni–Alevi tensions. At a local level the state has connived with this harassment, frequently to the point of persecution. Alevis harassed by Sunnis have seldom sought redress either from the police or the law courts since they believe the latter to be deeply prejudiced against them. In 1978 well over 100 Alevis were massacred in Maras by members of the extreme right National Action Party. In July 1993, 67 Alevis were killed in Sivas at the climax to the eight-hour siege of a hotel by Sunnis, while the police stood by. In March 1995 more than 20 Alevis were killed by vigilantes and police in Istanbul. Alevis remain economically underprivileged.
Targeting and attacks against Alevis have continued. In 2014, an Alevi man, Uğur Kurt, was shot and killed by police outside a cemevi in Istanbul while participating in a funeral ceremony for a relative; the family later won a court case and compensation.
