As one of the oldest tribes in Middle East, Kurds have a lot of historical and cultural things in common with Iranians. In the course of history, they have acted as a robust barrier in confrontation with the foreigners considering their geographical position. But, a pact was signed between the ottoman Sultan Salim I (1497-1506) and some Kurd leaders with the emergence of Shah Ismail I (1486-1509) and his adoption of some policies in respect to Kurd tribes as well as with the excitations Idris Bitlisi (death in 1502), as one of the thinkers and influential figures, who had joined ottomans following Chaldoran defeat; based on the pact, a vast part of Kurdish dwelling regions and numerous Kurd tribes were separated from Iran forever and accepted ottoman citizenship. Considering the subtle effects and persistence of this event for centuries on Iran-ottoman relations, on the one hand, and Iran-Kurds relations, on the other hand, the present study, meanwhile exploring the reasons and outcomes of this important incident, tries investigating the role of Idris Bitlisi in this regard using a descriptive-analytical method with an emphasis on first-hand resources.
