m part of the army into infantry. Fu Chien, however, with his
military organization that paid no attention to the tribal element,
created an infantry in addition to the great cavalry units, recruiting
for it large numbers of Chinese. The infantry proved extremely valuable,
especially in the fighting in the plains of north China and in laying
siege to fortified towns. Fu Chien thus very quickly achieved military
predominance over the neighbouring states. As we have seen already, he
annexed the "Earlier Yen" realm of the proto-Mongols (370), but he also
annihilated the Chinese "Earlier Liang" realm (376) and in the same year
the small Turkish Toba realm. This made him supreme over all north China
and stronger than any alien ruler before him. He had in his possession
both the ancient capitals, Ch'ang-an and Loyang; the whole of the rich
agricultural regions of north China belonged to him; he also controlled
the routes to Turkestan. He himself had a Chinese education, and he
attracted Chinese to his court; he protected the Buddhists; and he tried
in every way to make the whole country culturally Chinese. As soon as Fu
Chien had all north China in his power, as Liu Yuean and his Huns had
done before him, he resolved, like Liu Yuean, to make every effort to
gain the mastery over all China, to become emperor of China. Liu Yuean's
successors had not had the capacity for which such a venture called; Fu
Chien was to fail in it for other reasons. Yet, from a military point
of view, his chances were not bad. He had far more soldiers under his
command than the Chinese "Eastern Chin dynasty" which ruled the south,
and his troops were undoubtedly better. In the time of the founder of
the Tibetan dynasty the southern empire had been utterly defeated by his
troops (354), and the south Chinese were no stronger now.

Against them the north had these assets: the possession of the best
northern tillage, the control of the trade routes, and "Chinese" culture
and administration. At the time, however, these represented only
potentialities and not tangible realities. It would have taken ten to
twenty years to restore the capacities of the north after its
devastation in many wars, to reorganize commerce, and to set up a really
reliable administration, and thus to interlock the various elements and
consolidate the various tribes. But as early as 383 Fu Chien started his
great campaign against the south, with an army of something like a
million men
