erted to
central China, did Korea's importance begin to diminish. Although this
"Earlier Yen dynasty" of the Mu-jung officially entered on the heritage
of the Huns, and its regime was therefore dated only from 352 (until
370), it failed either to subjugate the whole realm of the "Later Chao"
or effectively to strengthen the state it had acquired. This old Hun
territory had suffered economically from the anti-agrarian nomad
tendency of the last of the Hun emperors; and unremunerative wars
against the Chinese in the south had done nothing to improve its
position. In addition to this, the realm of the Toba was dangerously
gaining strength on the flank of the new empire. But the most dangerous
enemy was in the west, on former Hun soil, in the province of
Shensi--Tibetans, who finally came forward once more with claims to
dominance. These were Tibetans of the P'u family, which later changed
its name to Fu. The head of the family had worked his way up as a leader
of Tibetan auxiliaries under the "Later Chao", gaining more and more
power and following. When under that dynasty the death of Shih Hu marked
the beginning of general dissolution, he gathered his Tibetans around
him in the west, declared himself independent of the Huns, and made
himself emperor of the "Earlier Ch'in dynasty" (351-394). He died in
355, and was followed after a short interregnum by Fu Chien (357-385),
who was unquestionably one of the most important figures of the fourth
century. This Tibetan empire ultimately defeated the "Earlier Yen
dynasty" and annexed the realm of the Mu-jung. Thus the Mu-jung Hsien-pi
came under the dominion of the Tibetans; they were distributed among a
number of places as garrisons of mounted troops.
The empire of the Tibetans was organized quite differently from the
empires of the Huns and the Hsien-pi tribes. The Tibetan organization
was purely military and had nothing to do with tribal structure. This
had its advantages, for the leader of such a formation had no need to
take account of tribal chieftains; he was answerable to no one and
possessed considerable personal power. Nor was there any need for him to
be of noble rank or descended from an old family. The Tibetan ruler Fu
Chien organized all his troops, including the non-Tibetans, on this
system, without regard to tribal membership.
Fu Chien's state showed another innovation: the armies of the Huns and
the Hsien-pi had consisted entirely of cavalry, for the nomads of
