Two basic systems of law, one Chinese, the other Mongol, coexisted in Eastern Asia. Because they arose from contrasting cultural bases, the systems were entirely different. Chinese law sprang from a settled agricultural way of life while the law of the Mongols arose from a nomadic, pastoral economy The Chinese developed the fundamental institutions of settled agrarian culture and law in the Far East which greatly influenced the peoples of Korea, Japan, Annam, and so forth. The Mongols unfolded the basic institutions of nomadic, pastoral law and culture which likewise affected the nomadic tribes of Asia which once formed parts of the empire of Jenghis Khan and his successors—the modern Buriats, Kirghiz, Tunguses, etc.
