Kaidu
Kaidu (c. 1230–1301), grandson of Ögedei Khan and great-grandson of Genghis Khan, was a Mongol ruler who led the Ögedeid house and served as de facto khan of the Chagatai Khanate, controlling territories in Central Asia including Bukhara and minting coins with his tamgha as evidence of sovereignty.[1][2]
His most defining conflict was the Kaidu–Kublai war (1268–1301), a protracted struggle against Kublai Khan's Yuan dynasty that challenged centralized Mongol authority, allied with figures like Duwa to consolidate the Chagatai Khanate, and ultimately contributed to the irreversible division of the empire into autonomous khanates following his death from battle wounds near Karakorum.[2][1]
