Before The Breakup of The Ilkhanate
The Injuids gained control of parts of Persia, mostly Fars, in 1304 at the beginning of the reign of the Ilkhan Öljeitü. The Ilkhan had given Sharaf al-Din Mahmud Shah control of the injü (the Mongol word for the royal estates). Sharaf al-Din was reportedly descended from 'Abd-Allah Ansari, an 11th century mystic of Herat. His son, Amir Ghiyas al-Din Kai-Khusrau, assisted another family, the Muzaffarids, in their takeover of Yazd. By 1325 Sharaf al-Din had gained nearly an absolute grip on the region. His power displeased Öljeitü's successor Abu Sa'id, who ordered Sharaf al-Din removed and sent a Sheikh Hussein ibn Juban to replace him. Kai-Khusrau, who ruled Shiraz for his father, resisted; and Sheikh Hussein was forced to return with an Ilkhan army. Also during Abu Sa'id's lifetime, Sharaf al-Din was imprisoned in Tabriz for a failed attempt to murder his successor.
