OcakorOdjak (Turkish: Ocak, Kurdish: Ocax, Azerbaijani: Ocaq, lit. 'hearth') is the particular religious community which adherents of Alevism belong to. In Alevi tradition, each ocak is led by a dede, who is assumed to be descended from sayyids.[1][2]
Ocaks are interconnected and there is a familial connection between them. At the top of the family tree is Haji Bektash Veli. There are people descended from every ocak. The Dedes which are the older sons of ocaks are in a higher position then the younger sons. This hierarchical structure is part of the "Hand in hand, Haqq" mentality.[3]
There are Dede ocaks in Turkey whose hierarchy has not been established due to the lack of research. The most well-known example is the Şücaeddin Veli.[4][5]
All Alevi Dedes are affiliated with a particular Ocak [lit. hearth]. Because of this, they are also called Ocakzade [lit. son of hearth]. The Ocakzade dedes are assumed to be descendants of the Prophet, and are accordingly called "seyyid".
