Shaikh Hasan-i Buzurg
Hasan Buzurg was married to Bagdad Katun the daughter of Amir Coban. Coban later became the most influential person at the court of Abu Sa'id Mirza. However, the Ilkhan soon became enamored with Bagdad Katun, and sought to have her divorce Hasan Buzurg. Coban sent the two of them to Qarabagh in an attempt to rid Bagdad Katun from Abu Sa'id's mind, but the effort failed, and Bagdad Katun was forced to marry the Ilkhan. After the murder of Coban in 1327, Bagdad Katun and the Grand Vizier Ghiyath al-Din Muhammad competed for influence over Abu Sa'id. Ghiyah al-Din spread a rumor that Bagdad Katun and Hasan Buzurg were plotting against the Ilkhan; Hasan Buzurg was arrested in 1332. His mother convinced the Ilkhan to spare his life, and he was imprisoned in the castle of Kamakh. In 1333, however, he was cleared and was sent to become governor of Rüm. During Abu Sa'id's lifetime, Hasan Buzurg was also called upon by Ghiyas al-Din to help stop rampant tax abuses in eastern Persia.
