Genghis Khan and the Making of the Modern World

by Jack Weatherford

As different as the Mongols were in many respects, the Chinese masses found more common ground with them in their taste and sensibilities than with their own Chinese court officials. Year by year, soldiers, officials, and peasants deserted the Sung to live under the Mongols or helped the Mongols to take over their local area. More merchants took their trade to the Mongols, more priests and scholars found protection and greater freedom of movement under the Mongols, and eventually Chinese generals and whole regiments of soldiers and sailors deserted to the Mongol lines. The collapse of the Sung dynasty was not a sudden fall or conquest, but a slow erosion as it fell apart.
