The role of the Great Wall in the Han Dynasty is concise, thank you.

At the end of Qin and the beginning of the Han Dynasty, the Xiongnu took advantage of the war in the Central Plains, crossed the Great Wall built by Qin Mengtian, and reverted to the Han Dynasty with the Great Wall of Qin, Zhao and Yan as the boundary. Due to the disrepair of this Great Wall and the scarcity of defenders in the north, the powerful Xiongnu continued to enter the Great Wall and plunder, until it went deep into Daigu, Taiyuan, Xihe, Shangjun, Beidi and other counties, and Han Gaozu, Emperor Hui, Emperor Wen, and Emperor Jing were forced to adopt a policy of peace with the Xiongnu; Marry the princess to Shan Yu for the Yan family (i.e., the queen), and give a large amount of wealth. However, it is such a dilapidated Great Wall, and it also plays a military defensive role to a certain extent, if it is not for the Xiongnu army, it generally cannot enter the Great Wall and plunder.

Secondly, if the defenders are effective, even if there is a Xiongnu army, they will not be able to enter the Great Wall. Cheng Buzhi is also a famous general who guards the Great Wall, and Li Guang is as famous, he governs the army very strictly, and defends against the Hun raid at any time, and the Huns do not dare to attack, which also shows that the Great Wall of the Warring States has played a certain role. Its guards Qing, Huo Quzhi, Gongsun He, Gongsun Ao and others attacked the Xiongnu, all of which took the Great Wall of Zhao and Qin as the main bases for attacking and retreating.

This shows that until the early Western Han Dynasty, the Great Wall of Qin, Zhao and Yan of the Warring States Period was still playing a military defensive role, although its defensive capability was much inferior to that of the Warring States Period. It was not until Emperor Wu of the Han Dynasty drove the Xiongnu to Mobei that he repaired the Great Wall of Qin and built the Great Wall of Outer Heaven built by Meng Tian, that the Great Wall of Qin, Zhao and Yan was abandoned, and its military defense role came to an end.

The beginning is only for the symbol of the emperor.

Later, with the change of time, it gradually evolved into a line of defense against the Xiongnu.

The role of the Great Wall in ancient times:

1. Defensive role. The Great Wall is the greatest military defense project in the ancient history of the world, it is not a simple isolated first-line city wall, but from point to line, from line to surface, the passes, military forts, gates and military towns along the Great Wall are connected into a tight network to form a complete defense system.

2. The Great Wall is the guarantee of peace and stability in ancient China's agricultural society. In the long history of more than 2,000 years, the rulers of successive dynasties have repelled the invasion of the northern nomads many times by virtue of the Great Wall, created a relatively flat production environment for the survival and development of the agricultural economy in feudal society, and also made the people's lives more stable.

3. The Great Wall is a position for cultural exchanges between various ethnic groups inside and outside the Great Wall, and a link to unite and unify a multi-ethnic country.

Region: The invasion of the northern nomads to the farming peoples of the Central Plains.

The main role of the construction of the Great Wall in ancient times was, firstly, to consolidate the imperial dynasty and prevent foreign invasion; Secondly, in order to better protect the territory, there are people standing guard at high places, so that they can find the enemy situation anytime and anywhere, and then burn the smoke of gunpowder to communicate; Finally, in order to show the majesty of the empire, it has a deterrent effect on the people below.

In ancient times, the Great Wall served as a barrier to defend against foreign enemies. Because the existence of the Great Wall increases the difficulty of intruders, it directly protects the stability of the country.

First, the most important role of the ancient Great Wall was to defend against foreign enemies. Second, a lot of labor was consumed in the process of building the ancient Great Wall.

The Great Wall is a military defense project in ancient China, it is a tall, strong and continuous long wall, which is used to limit the movement of the enemy, and the Great Wall is not a simple isolated city wall, but a defense system with the city wall as the main body, and a large number of cities, barriers, pavilions and standards.

Thousands of miles of land in China have been formed.

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 trading 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 the exchange and mutual complementarity between the two.

3. It also plays an important role in mediating the two economies and making the agricultural and animal husbandry economies develop in the direction of mutual cooperation between the main and auxiliary industries. Therefore, the Great Wall not only played the role of separating the two economies and cultures, but also shouldered the important task of closely binding the two economies and cultures together.

4. During the Qin and Han dynasties, nearly 10 million soldiers and civilians were invested. While building the Great Wall, Qin Shi Huang began to strengthen the development and construction of the border areas, which opened the prelude to the development of the border areas in Tuntian.

5. Due to the long time spent on the construction of the Great Wall in the Han Dynasty, many people put forward suggestions for immigrating to Shibian, and these suggestions were successively accepted and organized by the Han Dynasty.

6. Together with the soldiers guarding the Great Wall, the immigrants reclaimed wasteland for farming, which not only accelerated the economic development of the border area, saved a lot of military expenditures, but also greatly reduced the suffering of long-distance transportation, and spread Chinese culture far and wide.

7. In terms of culture, the Great Wall has also played an important role in the formation and development of the pluralistic and integrated pattern of the Chinese nation. The construction and defense of the Great Wall, as well as the battles in the Great Wall area, led to the extensive integration of the Han and more than a dozen ethnic minorities in ancient China.

8. In the third year of Emperor Xuan of the Han Dynasty (51 years ago), the Southern Xiongnu returned to the Han Dynasty, realizing the convergence of the Chinese Han nationality and the northern animal husbandry in the Central Plains agricultural area, which was the beginning of the formation of the Chinese nation.

The Great Wall is a general term for a series of city walls and fortresses built in ancient China to defend against invasions, mainly built from the Spring and Autumn Period and the Warring States Period to the Ming and Qing Dynasties. The Great Wall is of great strategic importance and historical value.

In ancient times, the northern region of China faced constant threats from foreign tribes. In order to protect the security of the country and the integrity of the territory, the Great Wall was built by various dynasties. By strengthening the defensive capabilities of the border defense line, the Great Wall made it difficult for the enemy to cross mountains, rivers and dangerous passes, and at the same time controlled the activities of merchants and maintained the stability of the country.

In addition, the Great Wall has an important symbolic significance in Chinese history and culture. The Great Wall represents the great history and civilization of China, and is one of the symbols of the Chinese people. At the same time, the structure and scale of the Great Wall also show the level of technology and architectural talent of ancient China.

Today, the Great Wall has become an important tourist attraction in China, attracting many domestic and foreign tourists to come for sightseeing and tourism. It is not only a symbol of Chinese culture, but also one of the masterpieces in the history of human civilization.

Maybe in everyone's impression, the Great Wall will have beacon towers, platforms and other fortifications, this is mainly the impression created by tourism now, the Great Wall we see in the scenic area has been repaired, and more TV series are also rendering in this direction, in fact, when it comes to the real role of the Great Wall, it is just a courtyard wall of the two big families of the Youchan farming people and the nomads, the farming people have built more, and the nomadic people are responsible for demolishing it, which is also the Inner Mongolia although it has the most Great Wall resources, There is one reason why there are very few left.

While we all now bemoan the demolition of the majestic Great Wall of Jin (built by Jin to defend against the Mongols led by Genghis Khan), the meaning is another interpretation from the perspective of ecological restoration and communication. Spike dust.

We know that the Great Wall is a fortification made by using the moat, through artificial changes, so that it becomes easier to defend and difficult to attack, of course, there must be the function of sentry and sentry, which is generally built with local materials, such as the Ming Great Wall near the mouth of the tiger, most of them are the Great Wall of earth, because there are not a large number of bricks and stones here, and the soil is not suitable for burning bricks, so the Ming Great Wall near the Qingshui River, no matter how majestic and magnificent, is the Great Wall of earth;

If you are fortunate enough to have been to the Great Wall of the Qin and Han Dynasties in Bayannur City, the Great Wall there is also built along the mountain range, it is said that Qin Shi Huang sent Meng Tian and Gongzi Fusu to build together, more like a "dry base" made of local materials, and now in the rural areas of the west, there is still such a custom, and most of their livestock pens are built with stones. I don't know if it's left over from that time.

Of course, in the Qin and Han dynasties, Juyan Gusai and Jilusai were also built with stone "dry bases", which were actually "courtyard walls" to separate the exchanges between the two ethnic groups in the past, and then sent troops to guard them in important positions in an attempt to prevent the northern nomads from coming.

Some people say that building the Great Wall is a waste of money and labor, it is better to be friendly, especially in the Qing Dynasty, the role of harmony has been brought to the extreme, and the princess's mansion is built on the grassland, the prince's mansion, and various summoning temples, everyone lives in peace and mutual benefit, and these courtyard walls are no longer needed, just like many parks and green spaces now, which used to be fenced, and now they have begun to open.

Here's a detailed introduction.

It was during the Qingchun Warring States Period, and various countries built the Great Wall in order to defend themselves.

From a distance, the Great Wall looks like a long dragon, winding and circling between the mountains. From Shanhaiguan in the east to Jiayuguan in the west, there are more than 13,000 miles.

Cure? I'm going to beat you to death, is it in my eyes?

During the Qin and Han dynasties, there was an unprecedented dialogue and exchange between the cultures of the north and the south of the Great Wall, such as the Qin Quan, the edict plate, the murals of the tombs of Inner Mongolia and Lingelhan, the Shan Yu and Qin Wadang, and the famous tomb of Zhaojun, all of which are witnesses of cultural exchanges and integration between the north and the south. In the cultural belt of the Great Wall area, there are many places of interest and historic sites left behind, such as Dunhuang, Yungang Grottoes, Maijishan, Wanfotang Grottoes, murals and sculptures, Juyongguan Yuntai in the Yuan Dynasty, Lugou Bridge in the Jin Dynasty and the ruins of Jinzhongdu and Yuan Dadu and the unearthed cultural relics, etc., all reflect the characteristics of cultural exchanges, and also record the glory of the culture in the history of the Chinese nation before the memory.

Since Qin Shi Huang, almost all dynasties that ruled the Central Plains have built the Great Wall. More than 10 dynasties, including the Han, Jin, Northern Wei, Eastern Wei, Western Wei, Northern Qi, Northern Zhou, Sui, Tangzai, Piqing, Song, Liao, Jin, Yuan, Ming, and Qing dynasties, all built the Great Wall on different scales. In terms of the ruling ethnic groups that built the Great Wall, in addition to the Han Chinese, many ethnic minority dynasties ruled China also built the Great Wall, and more than the Han ruled dynasties.

During the Kangxi period of the Qing Dynasty, although the large-scale construction of the Great Wall was stopped, the Great Wall was also built in individual places, and it can be said that the construction of the Great Wall has not been stopped for more than 2,000 years from the Spring and Autumn Period and the Warring States Period to the Qing Dynasty.
