note that the title of the commander of these armies,
_tu-tu_, in the fourth century meant a commander in the church-Taoist
organization; it was used by the Toba and from the seventh century on
became widely accepted as title among the Uigurs, Tibetans, Sogdians,
Turks and Khotanese.

When the prefectural armies and the militia forces weakened, special
regional armies were created (from 678 on); this institution had existed
among the Toba, but they had greatly reduced these armies after 500. The
commanders of these new T'ang armies soon became more important than the
civil administrators, because they commanded a number of districts
making up a whole province. This assured a better functioning of the
military machine, but put the governors-general in a position to pursue
a policy of their own, even against the central government. In addition
to this, the financial administration of their commands was put under
them, whereas in the past it had been in the hands of the civil
administration of the various provinces. The civil administration was
also reorganized (see the table on pages 83-84).

Towards the end of the T'ang period the state secretariat was set up in
two parts: it was in possession of all information about the economic
and political affairs of the empire, and it made the actual decisions.
Moreover, a number of technical departments had been created--in all, a
system that might compare favourably with European systems of the
eighteenth century. At the end of the T'ang period there was added to
this system a section for economic affairs, working quite independently
of it and directly under the emperor; it was staffed entirely with
economic or financial experts, while for the staffing of the other
departments no special qualification was demanded besides the passing of
the state examinations. In addition to these, at the end of the T'ang
period a new department was in preparation, a sort of Privy Council, a
mainly military organization, probably intended to control the generals
(section 3 of the table on page 83), just as the state secretariat
controlled the civil officials. The Privy Council became more and more
important in the tenth century and especially in the Mongol epoch. Its
absence in the early T'ang period gave the military governors much too
great freedom, ultimately with baneful results.

At first, however, the reforms of A.D. 624 worked well. The
administration showed energy, and taxes flowed in.
