Why the Great Wall was built, why the Great Wall was built

The Great Wall was developed from a castle and a fort. Castles and forts, which served as military defensive works, began as early as the end of the primitive commune.

A kind of passive fortification, in order to prevent the northern Xiongnu from raiding south, Qin unified the six countries and connected the Great Wall of the northern countries into one.

The original intention was to prevent the Xiongnu from attacking, but it did not actually play any role.

Kiss! The Great Wall of China is a great project, it is an outstanding representative of ancient Chinese civilization and one of the world's cultural heritage. The main reasons for the construction of the Great Wall are as follows:

Defend against foreign invasions: The most important function of the Great Wall is to defend against attacks by foreign enemies in the field. In Chinese history, it has often faced invasions from northern nomads.

In order to protect the security of the country and the people, all dynasties and dynasties built the Great Wall and set up border defense military facilities in the border areas. Conveying information and transportation: The Great Wall can also serve as a conduit for conveying important information and strengthening transportation links.

Especially in ancient China, due to the inconvenience of transportation and the imperfect postal system, the transportation of information and materials needed to be transported by land, so the Great Wall became an important passage connecting the east, west, north and south. Demonstrating the strength and dignity of the country: The construction of the Great Wall embodies the strength and dignity of a country, and is a symbol of China's civilization and strength to the outside world.

As a result, each dynasty regarded the construction of the Great Wall as an important undertaking to demonstrate the authority and majesty of the dynasty. To sum up, the construction of the Great Wall can be said to be a combination of historical and practical needs, and an important embodiment of Chinese civilization and national dignity. The construction of the Great Wall also reflects the development and changes of ancient Chinese society, politics, economy, military and other aspects, and has important historical and cultural significance.

The role of the Great Wall in Chinese history is very important. Here are a few reasons why the Great Wall was built:1

Defending the Frontier: Ancient China's northern borders were often plagued by foreign intrusions, and the Great Wall could deter invaders and secure China's borders. 2.

Maintain national unity: The original intention of the Great Wall was to prevent the invasion of the first faction such as the northern nomads (such as the Xiongnu), protect the rule of the ** dynasty, and maintain the unity of the country. 3.

Collection of customs duties: The Great Wall is an important route in China, which can collect customs duties from merchants in transit, bringing huge benefits to the national treasury. 4.

Strengthening military control: The construction of the Great Wall requires a lot of human, financial and material resources, and its existence shows that the state has unprecedented strength in military power and territorial governance. 5.

Strengthen national pride: The Chinese people regard the Great Wall as a symbol and pride of the country, and the Great Wall protects the territory of the motherland and strengthens the sense of national pride and belonging.

The Great Wall was built to resist the invasion of ethnic minorities such as the Xiongnu, Linhu, Donghu, and Loufu in the north.

During the Warring States Period, in order to resist the invasion of ethnic minorities such as the Xiongnu, Linhu, Donghu, and Loufu in the north, the vassal states of Qin, Yan, and Zhao had begun to build the Great Wall. However, while the Warring States states built the Great Wall against the northern nomads, they also built the Great Wall on the border between them.

After Qin Shi Huang unified the whole country, on the one hand, the Great Wall in the north of the countries was repaired and connected into one; On the other hand, the Great Wall between the Central Plains states was destroyed, so that the local separatist forces could no longer rely on it, so that true domestic unification could be achieved.

In the 30th year of Qin Shi Huang (217 BC), Pai Mengtian led an army of 300,000 to drive the Xiongnu north, and then because of the terrain, it took 9 years and countless manpower to build the Great Wall, starting from Lintao in the west and going to Liaodong in the east.

Because of the terrain, use danger to control the blockage", which very concisely summarizes the basic principles of designing the Great Wall route, because in this way, the best defense effect can be achieved with the least amount of manpower, capital and materials. This principle has been well implemented in the construction of later dynasties.

The Great Wall was built mainly to defend the country's Hail and Heng borders against foreign invasion. After Qin Shi Huang unified China, he built the Great Wall in order to prevent the invasion of the Xiongnu in the north. The construction of the Great Wall was also one of the reasons for the establishment of the Qin Dynasty and the closely related Yuanlu as a nation - the Xiongnu.

The defense engineering buildings of the Great Wall have accumulated rich experience in the construction process of more than 2,000 years, and the layout has summed up the important experience of "using danger to control the congestion due to the terrain".
