Abdul-Qadir Gilani
Ismail seized Baghdad in 1508. However, his armies zealously killed Sunnis and actively persecuted them through tribal allies of the Shah. His armies also destroyed several important Sunni sites, including the tombs of Abū Ḥanīfa and Abdul-Qadir Gilani. The Safavids even expelled the family of Gilani from Mesopotamia. After declaring Shiism the official form of Islam in Iraq, Ismail forced his new Iraqi subjects to convert to Shiism and outlawed Sunni practices. He then returned to Persia. These draconian actions by the conquering Safavids caused the Mesopotamian Sunnis to seethe with resentment.
