The Nusairis/Arabian Alawis are one of the religious groups living in the region of Hatay. The Institution of amca (religious uncle) is one of the important institutions in the Nusairis / Arabian Alawis in the tradi- tional sense. This institution is a major in-stitution that has existed for centuries such as the clergy class in the traditional sense and hierarchical levels. The religious teach- ing and values are passed on to new gener- ations significantly through this institution in the society. In this context, the process of training of the young persons who will be to Alawi/Nusairi way takes place under the guidance and observation of religious uncle. The relationship of the candidate, who is under training, with his family is cut during the educational process. This pro- cess covers the important period in terms of the transfer of religious teachings and values to new generations. The ceremony of road entrance is held by notifying of the case to Shaykh who has an important place in the clergy class when the religious uncle decided that the candidate no longer ma- tures and achieves a sufficient level. In this paper, we will try to evaluate the place and basic functions of the institu- tion of religious uncle in Nusairis with the general outline. In this framework, firstly the place and importance of the institu- tion of religious uncle in Nusairis/Arabian Alawis will be discussed and, the way that the institution works will be revealed. And then, the effect of the institution of religious uncle on on Nusairi society and its situa- tion of contemporary urban conditions will be discussed. The method we used in the working process includes the descriptive and analytic point of view rather than the critical and comparative point of view.
