h the Toba continued until 515. As a rule the Toba were
the more successful, not at least through the aid of princes of the
deposed "Southern Ch'i dynasty" and their followers. Wars began also in
the west, where the Toba tried to cut off the access of the Liang to the
caravan routes to Turkestan. In 507, however, the Toba suffered an
important defeat. The southern states had tried at all times to work
with the Kansu states against the northern states; the Toba now followed
suit and allied themselves with a large group of native chieftains of
the south, whom they incited to move against the Liang. This produced
great native unrest, especially in the provinces by the upper Yangtze.
The natives, who were steadily pushed back by the Chinese peasants, were
reduced to migrating into the mountain country or to working for the
Chinese in semi-servile conditions; and they were ready for revolt and
very glad to work with the Toba. The result of this unrest was not
decisive, but it greatly reduced the strength of the regions along the
upper Yangtze. Thus the main strength of the southern state was more
than ever confined to the Nanking region.

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.
