Too many antagonistic social and ethnic groups existed within the Yuan government to secure a stable rule. The traditional Chinese value system had largely disappeared, and no political ethics had replaced it. While personalized loyalty focused on the ruler, the companionship of nökör relations was not enough to amalgamate the heterogeneous ruling group into a stable body. This unbalanced system of government could function only under a strong ruler; under a weak or incompetent emperor, disintegration was certain, and a decline in efficiency resulted.
The former scholar-officials of China remained to a great extent outside the governmental and administrative structure; only minor positions were open to them. The Mongols never made full use of the administrative potential of the scholar-officials, fearing their competence and abilities. The ruling foreign minority in China was more an elite of the colonialist type than a part of the Chinese social system.
The unwillingness of the Mongols to assimilate with the Chinese is shown by their attempts to cement the inequalities of their rule. After the Song empire had been conquered, the population of China was divided into four classes. The first class was the Mongols themselves, a tiny but privileged minority. Next came the semuren (“persons with special status”), confederates of the Mongols such as Turks or Middle Eastern Muslims. The third group was called the hanren (a term that generally means Chinese but that was used to designate the inhabitants of only northern China); this class included the Chinese and other ethnic groups living in the former Jin state, as well as Xi Xia, Juchen, Khitan, Koreans, Bohai, and Tangut, who could be employed in some functions and who also formed military units under Mongol leadership. The last group was the nanren, or manzi, pejorative terms in Chinese, meaning “southern barbarian,” which designated the former subjects of Song China (about three-fourths of the Chinese empire). The lowest stratum in Yuan China was occupied by the slaves, whose numbers were quite considerable. Slave status was hereditary, and only under certain conditions could a slave be freed.
More than four-fifths of the taxpayers came from the nanren group, which was generally barred from holding higher office (only rarely would one of them rise to some prominence). The Mongols and the semuren were tax-exempt and enjoyed the protection of the law to a higher degree than did the hanren and nanren.
The formal distinction between various ethnic groups and the corresponding graded status was not a Mongol invention but a social differentiation inherited from the Jin state. In the same way, many institutions were taken over from the Jin. Law in Yuan China was based partly on the legislation of the Jin and partly on traditional Chinese law; Mongol legal practices and institutions also played a great role, particularly in penal law. The Yuan legal code has been preserved in the dynastic history, Yuanshi, as well as other sources. In addition, many rules, ordinances, and decisions of individual cases are collected in compilations such as Yuandianzhang, which throw much light not only on the legal system but also on social conditions in general.
Mongol and Chinese dualism is also reflected in the problem of administrative documents and languages. Few of the ruling Mongols, even in the later years of the Yuan, knew Chinese, and the number who mastered the Chinese script was still smaller. On the other hand, only a few Chinese bothered to learn the language of their conquerors. Administration and jurisdiction therefore had to rely largely on interpreters and translators. Mongol was the primary language; most decisions, ordinances, and decrees were originally drafted in Mongol, and a Chinese interlinear version was added. This Chinese version was in the colloquial language instead of the formal documentary style, and it followed the Mongol word order so that it must have seemed barbaric to the native literati. Many of these Chinese versions have survived in collections such as Yuandianzhang.
Economy
The Mongol conquest of the Song empire had, for the first time since the end of the Tang, reunified all of China. Song China had traded with its neighbours, the Liao and the Jin, but trade had been strictly controlled and limited to authorized border markets. The Mongol conquest therefore reintegrated China’s economy. The Mongol administration, in its desire to utilize the resources of the former Song territory, the most prosperous part of China, tried to promote internal trade and aimed at a fuller integration of north and south. The region around the capital was dependent on grain transports from the south, and large quantities of food and textiles were needed to keep the Mongol garrisons. The Grand Canal, which had linked the river systems of the Yangtze, the Huai, and the Huang since the early 7th century, was repaired and extended to Dadu in 1292–93 with the use of corvée (unpaid labour) under the supervision of a distinguished Chinese astronomer and hydraulic engineer, Guo Shoujing—an action entirely within Chinese tradition. This was preceded, however, by another measure in the field of economic communications that was unorthodox in Chinese eyes: about 1280, concessions for grain transport overseas were granted to some private Chinese entrepreneurs from the southeastern coastal region (some Chinese government officials were traditionally antagonistic toward private trade and enterprise, an attitude that the ruling Mongols did not share). These private shipowners transported in their fleets grain from the lower Yangtze region to northern Chinese harbours and from there to the capital. Early in the 14th century, however, these private fleet owners, who had made huge fortunes, were accused of treason and piracy, and the whole action was abolished. The Mongol government never replaced them with government fleets.
Another factor that contributed to the flourishing internal trade in China was standardized currency. The Song and Jin had issued paper money but only in addition to bronze coins, which had remained the basic legal tender. The Yuan government was the first to make paper money the only legal currency throughout the empire (1260). This facilitated financial transactions in the private sector as well as in the state treasuries. As long as the economy as such remained productive, the reliance on paper money as the basic currency had no detrimental effects. Only when the economy began to disintegrate under the last Mongol ruler did the paper money become gradually valueless and inflation set in. One reason for the paper currency might have been that much bronze and copper was used for the Buddhist cult and its statues, another that metal ores in China proper were insufficient to supply enough coins for some 80 million people.
Religious and intellectual life
The Mongols did not try to impose their own religion (a cult of heaven, the forces of nature, and shamanistic practices) on their subjects. This gave comparative freedom to the existing religions in China, including what the Mongol rulers considered to be the sanjiao (“three teachings”): Daoism, Buddhism, and Confucianism. Both Daoism and Buddhism retained their distinctive identities and organizations; although they often rivaled each other, they were not mutually exclusive. The Neo-Confucianism of the Zhu Xi school enjoyed orthodox status after the 1310s, but adherents of the three teachings interacted philosophically and intellectually in a way that popularized the “amalgamation” of the three schools among the common people and the literati, if not the foreign residents, of China.
Daoism
Under the Jin dynasty several popular Daoist sects had flourished in northern China, and Genghis Khan had apparently been impressed by the Daoist patriarch Changchun. In 1223 Genghis Khan granted to Changchun and his followers full exemption from taxes and other duties demanded by the government; this was the first of a series of edicts granting special privileges to the clergy of the various religions in China.
