despite Toregene's role in Güyük's accession. Against Toregene's wishes, Güyük had Toregene's favorite, Fatima, arrested, tortured and executed for bewitching his brother Koden (Khuden), and Abd-ur-Rahman was also beheaded for corruption. Of the provincial officials appointed under Toregene, only the Oirat official Arghun Aqa remained. Toregene herself died later, possibly at Güyük's orders. Güyük had Temüge's case investigated by Orda Khan and Möngke, and they had him executed. Güyük replaced the child khan Qara Hülëgü of the Chagatai Khanate with his favorite cousin Yesü Möngke to secure his position. He also restored his father's officials, Mahmud Yalavach, Masud Beg and Chinqai to positions in the provinces. Reign (1246–1248) Güyük reversed several unpopular edicts of his mother the regent and made a surprisingly capable khan, appointing Eljigidei in Persia in preparation for an attack on Baghdad and the Ismailis and pursuing the war against the Song Dynasty.

Due to Armenia's voluntary surrender, Sempad received a Mongol wife, and his kingdom was spared Mongol overseers and tax. Güyük demanded full-submission of the Abbasids and the Ismailis. Güyük Khan blamed Baiju for the irritated resistance of the Abbasid Caliphate. Güyük ordered an empire-wide census. In 1246, by the decree of Güyük, taxes amounting between to of value were imposed on everything and a heavy head tax of 60 silver drams was collected from males in Georgia and Armenia. The Great Khan separated the position of the great darughachi from that of chief scribe. Güyük took half of his father's kheshig for himself. Under his rule, the Uyghur officials increased their
