[6] Deportations of Kurds from present-day Turkish Kurdistan and South Caucasus to Khorasan were initiated by Ismail I and continued under Tahmasp I in the early 16th century.
In the following decades, five Kurdish domains were established in Khorasan by Abbas the Great stretching from Astarabad to Chenaran.
During the reign of Nader Shah, Kurds from Ardalan and those already deported to Khorasan were settled in Gilan Province.
[7] The main reason behind the deportations was the desire to create a defense-line against Turkmen and Uzbek nomads from Central Asia.
