onents rose, under the leadership of
Kao Tsu's family. Every member of the empress's family was exterminated,
and a son of Kao Tsu, known later under the name of Wen Ti (Emperor
Wen), came to the throne. He reigned from 179 to 157 B.C. Under him
there were still many fiefs, but with the limitation which the emperor
Kao Tsu had laid down shortly before his death: only members of the
imperial family should receive fiefs, to which the title of King was
attached. Thus all the more important fiefs were in the hands of the
imperial family, though this did not mean that rivalries came to an end.

On the whole Wen Ti's period of rule passed in comparative peace. For
the first time since the beginning of Chinese history, great areas of
continuous territory were under unified rule, without unending internal
warfare such as had existed under Shih Huang-ti and Kao Tsu. The
creation of so extensive a region of peace produced great economic
advance. The burdens that had lain on the peasant population were
reduced, especially since under Wen Ti the court was very frugal. The
population grew and cultivated fresh land, so that production increased
and with it the exchange of goods. The most outstanding sign of this was
the abandonment of restrictions on the minting of copper coin, in order
to prevent deflation through insufficiency of payment media. As a
consequence more taxes were brought in, partly in kind, partly in coin,
and this increased the power of the central government. The new gentry
streamed into the towns, their standard of living rose, and they made
themselves more and more into a class apart from the general population.
As people free from material cares, they were able to devote themselves
to scholarship. They went back to the old writings and studied them once
more. They even began to identify themselves with the nobles of feudal
times, to adopt the rules of good behaviour and the ceremonial described
in the Confucianist books, and very gradually, as time went on, to make
these their textbooks of good form. From this point the Confucianist
ideals first began to penetrate the official class recruited from the
gentry, and then the state organization itself. It was expected that an
official should be versed in Confucianism, and schools were set up for
Confucianist education. Around 100 B.C. this led to the introduction of
the examination system, which gradually became the one method of
selection of new officials. The system
