The evolution of China's legal tradition was one of the most striking aspects of the transformation of Chinese civilization under Mongolian domination. Paul Ch'en's exploration of the legal system of the Yuan dynasty (1271-1368) and its first substantial legal code (the Chih-yuan hsin-ko, or Chih-yiian New Code) provides a key to our understanding of the impact of the Mongols on traditional Chinese law and society. Originally published in 1979. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
