  In 1207, Genghis had appointed a man named Qorchi as governor of the subdued Hoi-yin Irgen tribes in Siberia. Appointed not for his talents but for prior services rendered, Qorchi's tendency to abduct women as concubines for his harem caused the tribes to rebel and take him prisoner in early 1216. The following year, they ambushed and killed Boroqul, one of Genghis's highest-ranking nökod. The khan was livid at the loss of his close friend and prepared to lead a retaliatory campaign; eventually dissuaded from this course, he dispatched his eldest son Jochi and a Dörbet commander. They managed to surprise and defeat the rebels, securing control over this economically important region.
  
  Kuchlug, the Naiman prince who had been defeated in 1204, had usurped the throne of the Central Asian Qara Khitai dynasty between 1211 and 1213. He was a greedy and arbitrary ruler who probably earned the enmity of the native Islamic populace whom he attempted to forcibly convert to Buddhism. Genghis reckoned that Kuchlug could be a threat to his empire, and Jebe was sent with an army of 20,000 cavalry to the city of Kashgar; he undermined Kuchlug's rule by emphasising the Mongol policies of religious tolerance and gained the loyalty of the local elite. Kuchlug was forced to flee southwards to the Pamir Mountains, but was captured by local hunters. Jebe had him beheaded and paraded his corpse through Qara Khitai, proclaiming the end of religious persecution in the region.
