Chagatai Khanate Succession Dispute (c. 1306)

Timeline

1. 1306Around Almaty (Ilay) · Chagatai KhanateAround 1306, the aging Duwa Khan's control over the khanate weakened, and imperial clan members including his son Kunshi and his nephew Chapar began competing for succession rights. Chapar, drawing on Transoxiana's military forces and the support of some princes, expanded in the Fergana basin, forming a standoff with Duwa's direct line and making the succession crisis public.
2. 1307Transoxiana · TransoxianaAfter Duwa Khan's death in 1307, Kunshi acceded with the support of some imperial princes, but Chapar refused to submit, continuing to control Transoxiana and the Ili region, creating a 'two khans side by side' division. The Yuan dynasty closely monitored the northwestern situation and began planning military intervention to restore its suzerainty over the Chagataids.
3. 1308Ili River valley · IliIn 1308, Yuan Wuzong (Khaishan) dispatched forces westward against Chapar. Under pressure from the Yuan army, Chapar was defeated, surrendered with his followers, and was escorted eastward. Kunshi's position was briefly consolidated, but the imperial clan division of the Chagatai Khanate was now settled; thereafter the khanate saw frequent changes of khan and continued political turmoil in Central Asia.
