Chamshgazak Kurdish tribe and protection of the northeastern borders of Iran after the eleventh century AH

One of the Kurdish tribes of Iran is the Chamshegzak tribe. This tribe lived in the areas of Diar Bakr and south of Arzanjan in the Ottoman Empire before the 11th century AH. Due to the Ottoman government's violent treatment of Shiites in eastern Anatolia, the Chamshgazak Shiite tribe migrated into Iran and settled in and around the Mahabad border region. Simultaneously with the formation of the Safavid Uzbek government, which came to power in Transoxiana, they repeated their attacks, depriving peace and security on the northeastern borders of Iran. Insecurity on the northeastern border of Iran was the main security problem of this government. One of the actions of the Safavid government was the migration of this tribe from northwestern Iran to the northeastern borders of the country. The tribe acted as a strong defensive wall to prevent Uzbek aggression and prevented them from invading central Iran. One of the main purposes of this article is to explain the reasons for the migration of this tribe to the northeastern border region of the country and the other purpose is to explain its defensive role against repeated Uzbek aggression. The study of the success factors of this tribe in achieving the above goals is the subject of this article, which is explained by descriptive-analytical method. Belief in the Shiite religion, racial courage and interest in the land and water of this land seem to have been the main factors in this success.
