The vast Mongol-Chinese empire founded by Kublai Khan. It was the realm of the Great Khan, heir to the Mongol Empire, and took its name, Great Yuan, from the Book of Changes. Choosing a Chinese classic rather than a Mongol title for the name of the state was itself a sign of the road this empire would take.
Legend says the Mongols descend from a blue wolf and a white deer sent by Heaven. Their descendants used the fighting power of the steppe to bring down the Southern Song and unify all of China.
Instead of Karakorum out on the steppe, Kublai built a new capital, Dadu, where Beijing stands today. It lay close to the grain-rich south, so feeding it was easy, and it was well placed for governing China. Dadu impressed Marco Polo, and merchants came to it from every direction.
What held the empire together was the relay system. Stations a day's ride apart kept horses and food ready, so anyone carrying a passport tablet could change mounts and keep going. News, goods and travellers moved along those roads.
The Yuan sorted people into Mongols, Semu from the west, Han of the old Jin lands, and southerners of the old Song lands, and gave each group different access to office and different taxes. It was how a small number of Mongols governed a far larger population, but resentment built among those placed at the bottom. At the same time the dynasty spread paper money, supported Tibetan Buddhism, and brought in astronomers and engineers from the west.
In the middle of the 14th century floods, failed harvests and heavy taxes set off revolts everywhere, and in 1368 the Yuan gave up Dadu and withdrew to the steppe. The state it kept going on the Mongolian plateau afterwards is known as the Northern Yuan.
