Chinggis Khan ruled the Mongol Empire for twenty-one years. In that time, he established a law code, the yassa, that he hoped would allow his seminomadic people to live in harmony. He saw the people living in settled areas, such as the Xi Xia, Jin, and Khwarazmians, as a source of wealth and tribute. The empire changed enormously during Chinggis Khan’s reign, becoming more inwardly peaceful but also much more materialistic in its tastes. The military changed as well, becoming a sophisticated war machine capable of surprise attacks and deadly sieges. Chinggis Khan’s son Ogedei steered the empire toward his father’s vision of a united people, overseeing a peaceful Eurasia-wide exchange of goods and collection of taxes, and he expanded the empire to make it happen. Equally important, Ogedei undertook the development of the bureaucracy and infrastructure necessary to support trade on a large scale. Due to Ogedei’s lack of foresight in planning for succession, however, the reign of Chinggis Khan’s grandson Mongke marked the end of a united Mongol Empire. When Mongke’s brother Kublai succeeded him as great khan, the empire was beginning to divide into those who preferred the old nomadic ways and those who had adopted a settled lifestyle of wealth and trade.
