genghis khan's great army's

After Genghis Khan's death, the empire was divided into four kingdoms, or "Khanates". One of these, the "Great Khanate," comprised the Mongol homeland and China, and its emperors were known as the Yuan Dynasty. Its founder, Kublai Khan, set up his centre in present day Beijing. After more than a century of power, the Yuan Dynasty was replaced by the Ming Dynasty in 1368, and the Mongol court fled north. The Ming armies pursued and defeated them in Mongolia, but were not able to conquer Mongolia. However, they were successful in sacking and destroying the Mongol capital Karakorum and other cities in 1380. The Chinese wiped out the cultural progress of the Mongols achieved during the imperial period and Mongolia was thrown back to the primitive state until the renaissance of the 16th-17th centuries.
