Division of the Chagatai Khanate

Timeline

1. 1270–1274Ferghana (Fergana) · Fergana BasinThe Chagatai descendant Baraq was raised to the khanship by the princes, but his rule was weak, relations with Abaqa of the Ilkhanate and eastern princes were tense, factions proliferated, and military and civil commands could not be unified.
2. 1275–1278Samarkand · TransoxianaThe prince Taliqu overthrew Baraq and declared himself khan, only to be assassinated soon after; the Chagatai khanship changed hands several times within a few years, local military governors and princes each acting independently, and the khanate effectively split into multiple rival blocs.
3. 1278–1279Seven Rivers region · Seven Rivers regionKaidu's forces expanded across the Seven Rivers and north and south of the Tianshan, forming an east–west standoff with the princes of Transoxiana; though nominally still a Mongol vassal, the Chagatai Khanate had in fact split into multiple uncoordinated political units, laying the groundwork for the long Kaidu–Duwa wars of the 1280s.
