In
the year 221 BC, Emperor
Qin Shihuang defeated all his enemies and unified China for
the first time in its history. During his reign, the Huns from the
north were a constant threat, often coming down to the Yellow
River Basin and taking land from people in the Hetao Area, located
at the top of the Great Bend of the Yellow River in Ningxia and
Inner Mongolia. To protect his people and safeguard his political
power, the Emperor ordered General Meng Tian, commanding 300,000
soldiers, to defeat the enemy force. To prevent further attacks
by the Huns, he decided to consolidate and extend the Great Wall.
Many people believed that it was Emperor Qin Shihuang who first
built the Great Wall. But research showed that before Qin's Great
Wall, the six ducal states had already built their own walls to
prevent attacks from each other and the Huns. Qin's Great Wall was
built by connecting parts of the walls belonging to the past ducal
states Qin, Zhao and Yan, plus adding several thousand miles of
its own. The Great Wall of Qin resembled a gigantic dragon, extending
from Lintao in the west to Liaodong in the east. Thus it was named
'Wanli Changcheng' (Ten Thousand Li Great Wall)
Generally speaking, Qin's Great Wall can be divided into three
sections: western, middle and eastern. The western section started
from the present Min County in Gansu Province, winding its way to
Inner Mongolia via Guyuan County in Gansu Province; Jingbian, Yulin,
Shenmu in Shaanxi Province; ending at the south bank of the Yellow
River. The middle section started from Xinghe County in Inner Mongolia,
winding its way to the north border of Wulanbuhe desert by way of
Daqingshan Mountain, Guyuan County, Yinshan Mountain and the Yellow
River. This part of the Great Wall was built mainly by using rubbles
left from existing walls. The eastern section started from Huade
County, Inner Mongolia, through Hebei Province, ending in Fuxin
City in Liaoning Province. This part of the wall was built on the
foundation of the ruins of Yan Dynasty walls.
It took about nine years to finish this grand project. The construction
of the Qin Great Wall took many lives and a great deal of money
and materials. From a historical aspect, during Qin Shihuang's rule,
the Great Wall had served its role as a defensive force to protect
people from wars and ensured them a peaceful and stable society.
