The Yuan dynasty was an imperial dynasty of China, proclaimed on 18 December 1271 by Kublai Khan, which succeeded the Song dynasty and preceded the Ming dynasty. It also functioned as a continuation of the Mongol Empire, which was founded by Genghis Khan in 1206, but which subsequently split into four autonomous states. The emperors of the Yuan dynasty thus comprise both Kublai's successors as rulers of China and his predecessors up to his grandfather Genghis, who was retrospectively presented as the founder of the dynasty.
The rulers of the Yuan dynasty were nominally superior to those of the other three post-Mongol states, but each was de facto independent of the others and occupied with their own territories. The Yuan dynasty adopted Han political traditions, including the use of posthumous names, temple names and era names. Aside from the title of emperor, Yuan rulers also concurrently held the title of khagan.
