The unequal treaties imposed on China by western powers after 1840 had two huge and complicated impacts on the social transition in China. The reform of the traditional Chinese law was carried out against the general background of social transition and directly motivated by the issue of consular jurisdiction. In late Qing Dynasty，the government carried out an all-round legal reform，marking the disintegration of the traditional Chinese legal system and the beginning of the modernization of the Chinese law. After the establishment of the Nanjing Government in 1927，the pace of legal modernization quickened. The establishment of the “Six-Law System” marked the preliminary completion of the modernization of Chinese law. The success of the modernization of the Chinese law depended on the organic unification of the logic of the philosophy of law with the logic of history.
