The Mongols carved out the largest land-based empire in world history, stretching from Korea to Russia in the north and from China to Syria in the south in the thirteenth century. Along with their leader Chinggis Khan they conjure up images of plunder and total destruction. Although this book does not ignore the devastation and killings wrought by the Mongols, it also reveals their contributions to governance, arts, culture, and the promotion of trade. The Mongol peace resulted in considerable travel and relations among numerous merchants, scientists, artists, missionaries, and entertainers of different ethnic groups. It is no accident that Europeans, including Marco Polo, first reached China in this period. Eurasian and perhaps global history starts with the Mongol empire.
