Kublai Khan by John Man

A brisk, narrative portrait of the Mongol ruler who transformed from steppe conqueror into emperor of China, detailing his military campaigns and the conquest of the Southern Song, his creation of the Yuan administrative system blending Mongol and Chinese institutions, his patronage of trade, religion and the arts (and contacts with travelers like Marco Polo), and the court intrigues, costly maritime expeditions and succession struggles that shaped both his reign and his complex legacy.
