The Mîlan tribe had been in Raqqa since 1711. The Ottomans issued an order to deport them from the Nahid Al-Jilab region to the Raqqa area. However most of the tribe was returned to their original home as a result of diseases among their cattle and frequent deaths due to the Raqqa climate. In the mid-18th century, the Ottomans recognised the Kurdish tribal chiefs and appointed Mahmud Kalash Abdi as head of the iskân policy in the region. The tribal chiefs had the power to impose taxes and control over other tribes in the region.
