Historical materials of the Great Wall

The history of the construction of the Great Wall can be traced back to the Western Zhou Dynasty, and the famous allusion "bonfire drama princes" occurred in Haojing, the capital (now Xi 'an, Shaanxi) originated from this.

During the Spring and Autumn Period and the Warring States Period, countries competed for hegemony and defended each other, and the construction of the Great Wall entered its first climax, but the construction length at this time was relatively short. After Qin destroyed the six countries and unified the world, Qin Shihuang connected and repaired the Great Wall of the Warring States Period, which was called the Great Wall of Wan Li. The Ming Dynasty was the last dynasty to overhaul the Great Wall, and most of the Great Wall seen by people today was built at this time.

The Great Wall is mainly distributed in Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia and Xinjiang 15 provinces, autonomous regions and municipalities.

Shaanxi Province is the province with the richest resources of the Great Wall in China, with a total length of 1838 km. According to the results of the national Great Wall resources survey conducted by cultural relics and surveying and mapping departments, the total length of the Great Wall in Ming Dynasty was 885 1.8km, and it was more than 1 1,000 km in Qin and Han Dynasties and its early period, and the total length was more than 2 1 1,000 km.

Construction history:

The Great Wall is an ancient defense project with the longest construction time and the largest engineering quantity in China and even in the world. Since the Western Zhou Dynasty, it has been built continuously for more than 2,000 years, distributed in the vast land in northern and central China, with a total length of more than 50,000 kilometers.

Since Qin Shihuang, almost all dynasties that ruled the Central Plains have built the Great Wall. There are more than ten dynasties such as Han, Jin, Northern Wei, Eastern Wei, Western Wei, Northern Qi, Northern Zhou, Sui, Tang, Song, Liao, Jin, Yuan, Ming and Qing, all of which have built the Great Wall of different scales.

Judging from the ruling nationalities who built the Great Wall, besides the Han nationality, many dynasties in which ethnic minorities ruled China also built the Great Wall, more than those ruled by the Han nationality.

During the Kangxi period of the Qing Dynasty, although the construction of the Great Wall was stopped on a large scale, it was later built in some places. It can be said that from the Spring and Autumn Period and the Warring States Period to the Qing Dynasty, the construction of the Great Wall has never stopped for more than two thousand years.

According to historical documents, more than 20 vassal states and feudal dynasties built the Great Wall. If you add up the Great Wall built in different times, it is more than 10 in Wan Li, and the length of the Great Wall in Qin, Han and Ming dynasties exceeds 1 Wan Li.
