In this paper the socio- political role of Qaderieh Tariqat resided in Kurdish Iraq (1918- 1931) has been studied. Qaderieh, specially Barzanji branch survived after the decline of Baban administration in 1851 to put its long desire into trial. They could ultimately succeed to take the highest political position in 1918- 1931. The main question is why could the Qaderieh Dervishi Tariqat reach to the central point of power in Kurdish Iraq? Taking sociological approach by applying Durkhim’s social solidarity theory and studying on original resources, the research approves that Dervishi well- established organization would not have been able to succeed if they had failed to build social solidarity within the crisis-ridden Kurdish society.
