The Kaidu–Kublai war was a war between Kaidu, the leader of the House of Ögedei and the de facto khan of the Chagatai Khanate in Central Asia, and Kublai Khan, the founder of the Yuan dynasty in China and his successor Temür Khan that lasted a few decades from 1268 to 1301. It followed the Toluid Civil War (1260–1264) and resulted in the permanent division of the Mongol Empire. By the time of Kublai's death in 1294, the Mongol Empire had fractured into four separate khanates or empires: the Golden Horde khanate in the northwest, the Chagatai Khanate in the middle, the Ilkhanate in the southwest, and the Yuan dynasty in the east based in modern-day Beijing. Although Temür Khan later made peace with the three western khanates in 1304 after Kaidu's death, the four khanates continued their own separate development and fell at different times.
