In 936 the Later T'ang dynasty gave place to the Later Chin dynasty (936-946), but this involved no change in the structure of the empire. The change of dynasty meant no more than that instead of the son following the father the son-in-law had ascended the throne. It was of more importance that the son-in-law, the Sha-t'o Turk Shih Ching-t'ang, succeeded in doing this by allying himself with the Kitan and ceding to them some of the northern provinces. The youthful successor, however, of the first ruler of this dynasty was soon made to realize that the Kitan regarded the founding of his dynasty as no more than a transition stage on the way to their annexation of the whole of North China. The old Sha-t'o nobles, who had not been sinified in the slightest, suggested a preventive war; the actual court group, strongly sinified, hesitated, but ultimately were unable to avoid war. The war was very quickly decided by several governors in eastern China going over to the Kitan, who had promised them the imperial title. In the course of 946-7 the Kitan occupied the capital and almost the whole of the country. In 947 the Kitan ruler proclaimed himself emperor of the Kitan and the Chinese. [Illustration: Map 6: The State of the later Tang dynasty] The Chinese gentry seem to have accepted this situation because a Kitan emperor was just as acceptable to them as a Sha-t'o emperor; but the Sha-t'o were not prepared to submit to the Kitan régime, because under it they would have lost their position of privilege. At the head of this opposition group stood the Sha-t'o general Liu Chih-yüan, who founded the "Later Han dynasty" (947-950). He was able to hold out against the Kitan only because in 947 the Kitan emperor died and his son had to leave China and retreat to the north; fighting had broken out between the empress dowager, who had some Chinese support, and the young heir to the throne. The new Turkish dynasty, however, was unable to withstand the internal Chinese resistance. Its founder died in 948, and his son, owing to his youth, was entirely in the hands of a court clique. In his effort to free himself from the tutelage of this group he made a miscalculation, for the men on whom he thought he could depend were largely supporters of the clique. So he lost his throne and his life, and a Chinese general, Kuo Wei, took his place, founding the "Later Chou dynasty" (951-959).
