The first emperor of the Liang dynasty, who assumed the name Wu Ti (502-549), became well known in the Western world owing to his love of literature and of Buddhism. After he had come to the throne with the aid of his followers, he took no further interest in politics; he left that to his court clique. From now on, however, the political initiative really belonged to the north. At this time there began in the Toba empire the risings of tribal leaders against the government which we have fully described above. One of these leaders, Hou Ching, who had become powerful as a military leader in the north, tried in 547 to conclude a private alliance with the Liang to strengthen his own position. At the same time the ruler of the northern state of the "Northern Ch'i", then in process of formation, himself wanted to negotiate an alliance with the Liang, in order to be able to get rid of Hou Ching. There was indecision in Liang. Hou Ching, who had been getting into difficulties, now negotiated with a dissatisfied prince in Liang, invaded the country in 548 with the prince's aid, captured the capital in 549, and killed Emperor Wu. Hou Ching now staged the usual spectacle: he put a puppet on the imperial throne, deposed him eighteen months later and made himself emperor. This man of the Toba on the throne of South China was unable, however, to maintain his position; he had not sufficient backing. He was at war with the new rulers in the northern empire, and his own army, which was not very large, melted away; above all, he proceeded with excessive harshness against the helpers who had gained access for him to the Liang, and thereafter he failed to secure a following from among the leading cliques at court. In 552 he was driven out by a Chinese army led by one of the princes and was killed. The new emperor had been a prince in the upper Yangtze region, and his closest associates were engaged there. They did not want to move to the distant capital, Nanking, because their private financial interests would have suffered. The emperor therefore remained in the city now called Hankow. He left the eastern territory in the hands of two powerful generals, one of whom belonged to the Ch'en family, which he no longer had the strength to remove. In this situation the generals in the east made themselves independent, and this naturally produced tension at once between the east and the west of the Liang empire; this tension was now exploited by the leaders of the Chou state then in the making in the north. On the invitation of a clique in the south and with its support, the Chou invaded the present province of Hupei and in 555 captured the Liang emperor's capital. They were now able to achieve their old ambition: a prince of the Chou dynasty was installed as a feudatory of the north, reigning until 587 in the present Hankow. He was permitted to call his quasi-feudal territory a kingdom and his dynasty, as we know already, the "Later Liang dynasty".
