SOCIAL CLASSES: SUB-ELITE AND COMMONER 651
The central features of this military system were hereditary status, separa-
tion from the society at large in their relation to the government, and direct
subordination to the Bureau of Military Affairs (Shu-mi yuan) through re-
gional and local military officials. There is administrative logic in this way of
solving the military needs of the time if
one
overlooks the nature of Chinese
society. The system, once in place, was kept in force through the century of
Yuan history. Its defects, obvious as time wore on, were frequently criticized,
but no essential changes were made. This institutional rigidity was character-
istic of many aspects of Yuan history after Khubilai's reign.
From the beginning, this military system ran counter to the ideological
and organizational tendencies of Chinese society. Chinese men seldom
wanted to be soldiers, and when restricted to that disdained career, they often
sought ways to escape. The favors accruing to their professional status did not
outweigh the liabilities. Initially, and through the conquest of the Southern
Sung, the system served to supply large numbers of soldiers at minimal cost
in money and management. Thereafter, under the sharply declining adminis-
trative effectiveness after Khubilai's reign, it also became clear that the Yuan
military machine, although it continued to function more successfully where
Mongolian units were involved, was by and large undermanned, badly
trained, undisciplined, and lacking in proper equipment to the point of
being useless. Late in the dynasty, local warlord armies, some nominally loyal
to the regime and others in open rebellion against it, repeatedly demon-
strated that the Mongolian government no longer commanded a reliable force
with which to coerce them or the population at large. General disorder and
civil war ended the dynasty. It had been founded by means of military
superiority, and it fell because of military weakness.
A number of factors contributed to that failure. One was the Mongols'
uncertainty about how far to accept non-Mongolian soldiers or generals as full
partners. In the civilian sphere Chinese officials could bear the main burdens
of daily work but were not admitted to the highest ranks of decision-making
officialdom. The infiltration of Chinese into the military, even as lower-
ranking officers and soldiers, was a still more sensitive issue. The Mongols
did not wish to create among the Chinese population any military force that
might encourage a centrifugal military tradition, one whose interests could
diverge from Mongolian priorities.
Before Khubilai's reign, when the problems of governing a sedentary
Chinese population had not yet assumed high importance, Chinese warlords
were given full acceptance as able associates; they enjoyed high rank and trust
as long as they demonstrated military abilities. During Khubilai's reign, the
emphasis was on institutional regularization. The most powerful northern
Chinese warlords and their myriarchies were brought under closer control.
