Qin, the First United Empire (221-206
The ruler of Qin used the theory of legalists who advocated that
law should be made and should be strictly executed. The ruler called
himself Qinshihuang (First Emperor of Qin Dynasty's). He ordered
to connect the Great Wall. He not only united China through military
forces, but also unified weights and measures, introduced a standard
currency, and applied a Qin writing style. In addition, he also
developed the main road and canal system. He also attempted to unify
thoughts in order to better control his people. His name is forever
tied with the "Burning the Books and Burying the Scholars"
because he ordered all books except those on medicine, agriculture
and divination burnt and many prominent scholars buried alive for
their different opinions.
His ruthlessness and much expensive cost on building his palace,
his tomb, the road and the Wall depleted the wealth of his country.
Qin Dynasty was overthrown not long after his death.
Qinshihuang left behind a form of political organization, which
was to endure for some 2,000 years. The most remarkable innovation
was the bureaucratic apparatus that remained in the following dynasties.
