Wan Li Great Wall was built by which emperor in China?

In the 26th year of Qin Shihuang (22 1 year), Qin annexed six countries, unified the world and established the first unified multi-ethnic centralized country in China history. In order to maintain and consolidate the unprecedented unity and security of the Great Empire, Qin Shihuang successively adopted a series of major strategic measures for national defense construction and frontier defense, one of which was the large-scale construction of the Great Wall of Wan Li.

In the thirty-second year of Qin Shihuang (2 15), General Meng Tian led 300,000 troops to attack the Huns in the north and took the land of Henan. Later, the Great Wall was built, winding from Lintao (now Shanni County, Gansu Province) in the west to Liaodong (now Liaoning Province) in the east for more than 10,000 miles. Since Qin Shihuang built the Great Wall, it has been called the Great Wall of Wan Li.

From the Qin and Han Dynasties to the Ming and Qing Dynasties, many passes along the Great Wall became places or centers for ethnic transactions in the two major economic and cultural systems of agriculture and animal husbandry, and some gradually developed into important towns along the Great Wall. The Great Wall not only ensures the normal development of agricultural economy, culture and animal husbandry economy and culture, but also provides a place and convenience for their exchange and complementarity.

It also plays an important role in mediating the two economies and making the agriculture and animal husbandry economy develop in the direction of mutual assistance. Therefore, the Great Wall not only plays the role of isolating the two economies and cultures, but also shoulders the heavy responsibility of closely linking the two economies and cultures.

During the Qin and Han Dynasties, there were nearly ten million soldiers and civilians. While building the Great Wall, Qin Shihuang began to strengthen the development and construction of border areas, which opened the prelude to stationing farmland to defend the border and developing the border areas.

Because it took a long time to build the Great Wall in the Han Dynasty, many people put forward suggestions on immigration, which were adopted and implemented by the Han government. Immigrants and soldiers guarding the Great Wall cultivated wasteland together, which not only accelerated the economic development of the border region, saved a lot of government military expenditure, but also greatly reduced the pain of long-distance transportation and made Chinese culture spread farther and wider.
