Historical development of Qadiriyya in Upper Euphrates Basin (1797-1973)

Sufism is one of the formations in the basin of culture and civilization of the Islamic world, which takes on the internal dimension of man and makes him adopt moral beauties and gain religious experiences. This formation has changed over time with people's differing lives, thoughts and interpretations, and thus different schools of Sufism have emerged. These schools of mysticism were represented under the leadership of a master and the necessary teachings reached the people through the so-called sect. As a result of the differences in the pedestals applied over time, the branches were divided in the sects provided that their teachings remained essentially the same. The new branches were named after Mürşidi Kamil, who was compared to him.
