About 450 began the Toba policy of shifting the central government to the region of the Yellow River, to Loyang; for this purpose the frontier had to be pushed farther south. Their great campaign brought the Toba in 450 down to the Yangtze. The Sung suffered a heavy defeat; they had to pay tribute, and the Toba annexed parts of their northern territory.
The Sung emperors who followed were as impotent as their predecessors and personally much more repulsive. Nothing happened at court but drinking, licentiousness, and continual murders.
From 460 onward there were a number of important risings of princes; in some of them the Toba had a hand. They hoped by supporting one or another of the pretenders to gain overlordship over the whole of the southern empire. In these struggles in the south the Hsiao family, thanks mainly to General Hsiao Tao-ch'eng, steadily gained in power, especially as the family was united by marriage with the imperial house. In 477 Hsiao Tao-ch'eng finally had the emperor killed by an accomplice, the son of a shamaness; he set a boy on the throne and made himself regent. Very soon after this the boy emperor and all the members of the imperial family were murdered, and Hsiao Tao-ch'eng created the "Southern Ch'i" dynasty (479-501). Once more the remaining followers of the deposed dynasty fled northward to the Toba, and at once fighting between Toba and the south began again.
This fighting ended with a victory for the Toba and with the final establishment of the Toba in the new capital of Loyang. South China was heavily defeated again and again, but never finally conquered. There were intervals of peace. In the years between 480 and 490 there was less disorder in the south, at all events in internal affairs. Princes were more often appointed to governorships, and the influence of the cliques was thus weakened. In spite of this, a stable régime was not built up, and in 494 a prince rose against the youthful emperor. This prince, with the help of his clique including the Ch'en family, which later attained importance, won the day, murdered the emperor, and became emperor himself. All that is recorded about him is that he fought unsuccessfully against the Toba, and that he had the whole of his own family
killed out of fear that one of its members might act exactly as he had done. After his death there were conflicts between the emperor's few remaining relatives; in these the Toba again had a hand. The victor was a person named Hsiao Yen; he removed the reigning emperor in the usual way and made himself emperor. Although he belonged to the imperial family, he altered the name of the dynasty, and reigned from 502 as the first emperor of the "Liang dynasty".
