Ariq Böke
Kublai's victories left Alghu as Ariq Böke's only standing ally. Ariq Böke convinced Alghu to take control of the Chagatai Khanate in Central Asia. Chagatai's khan, Qara Hülëgü, had recently died. Alghu fought and killed Abishkha, a rival claimant to the throne endorsed by Kublai as ruler of the khanate. Alghu was one of Ariq Böke's strongest supporters and he appointed him khan of Chagatai. The khanate became an important source of Ariq Böke's provisions. Ariq Böke gave Alghu complete control over tax revenues in the region.
