Chart the disintegration of the Mongol Empire, observing its rapid collapse in the Persian Ilkhanate in 1335 and Yuan China in 1368. Also, analyze the much more gradual break-up of the Chagatayid khanate and the Golden Horde, as the Mongols splintered into smaller, more autonomous units. Finally, focus on some of the long-lived successor states to the Mongols, such as the Ming dynasty in China.
