A cemevi or cem evi (pronounced and sometimes written as djemevi; meaning literally "a house of gathering" in Turkish) is a place of fundamental importance for Turkey's Alevi-Bektashiyyah tariqa populations.
The structuring of cemevi as into their present characteristics and rites owes much to the Bektashi tradition within various historical currents of Turkey's Alevi culture.
In larger towns in Turkey today, cemevi are multi functional buildings where a broad range of cultural activities take place.
For those who recognize it as religious, they consider it a form of Islam (often, a branch of Shia'ism), while a few claim it to represent an independent, non-Islamic religion (a radical position held by relatively few adherents).
Besides historical or theological grievances, the issues often center around outbreaks of anti-Alevi violence, complaints of systematic discrimination, and official non-recognition of Alevi identity.
