Hulegu confirmed Hajjaj as the new ruler of Kerman, while Kutlugh Turkan was named a regent responsible for civil affairs.
Hajjaj's brother-in-law Azad al-Din Hajji was confirmed as the supreme commander, much to Turkan's displeasure, who later obtained full sovereign rights.

According to "History of Qara-Khitai Shahs" (Tāriḵ-e šāhi-e Qarāḵtāʾiān), he grew ambitious and asked Turkan to dance in front of her while his followers chanted "The sky and the stars are old.
This plot was revealed when some of his ministers and commanders, including Taj al-Din Satilmish defected to Turkan, who in turn asked for Abaqa's interference.
