Khorasan Dervishes, including "Haci Bektas-i Veli" the great Turkish thinker, had mixed up in the same cultural crucible Christian communities living in Anatolia with Turkmen groups come by immigration, through activities of education and reconstruction, and had not played a vital role in creation of cultural integrity in Anatolia and constitution of Central Authority. A number of Dervishes who had come to Anatolia by way of immigration settled in secluded road junctions, opened lodges (Zaviye) there, and these institutions established on unsettled territories had been converted into centers of culture, reconstruction and religion in time.
Thus religious communities had been spread out everywhere; rules of ethic, decency, behaviour, belief had been standardised, knowledge and science had been produced and expanded in these centers within the framework of availabilities of the era. These Dervishes had settled in villages and cultivated soil and dealt with education had been also supported by Rulers, and a number of privileges had been granted to Dervishes. Consequently lodges had been set up even at the most remote corners of Anatolia and a common cultural texture had been commenced forming thanks to the education provided.
