What role does the Great Wall play in history?

1. From the Qin and Han Dynasties to the Ming and Qing Dynasties, many passes along the Great Wall became places or centers for ethnic trade in the two major economic and cultural systems of agriculture and animal husbandry, and some gradually developed into important towns along the Great Wall.

2. 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.

3. 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.

In Han Dynasty, because it took a long time to build the Great Wall, many people put forward suggestions on immigration, which were adopted and implemented by the Han government.

6. Immigrants and soldiers guarding the Great Wall cultivated wasteland together for farming, which not only accelerated the economic development of the border region, saved a lot of military expenses of the government, but also greatly reduced the pain of long-distance transportation and spread Chinese culture farther and wider.

7. Culturally, the Great Wall has also played an important role in the formation and development of the pluralistic and integrated pattern of the Chinese nation. On the contrary, the construction and defense of the Great Wall and the war in the Great Wall area promoted the extensive integration of the Han nationality in ancient China and a dozen ethnic minorities.

8. In the third year of Ganlu (5 1 year ago), the southern Xiongnu returned to Han, which realized the intersection of the Han nationality in China and the northern pastoral nationality in the Central Plains agricultural area, and was the beginning of the formation of the Chinese nation.
