The History of the Great Wall of China
The Great Wall of China has a history of more than 2,000 years. The Great Wall of China’s history began in the Spring and Autumn Period (770–476 BC) and was last rebuilt as a defense in the Ming Dynasty (1368–1644).
During the Spring and Autumn Period (770–476 BC) and the Warring States Period (475–221 BC) when the eastern and central region of what is now China consisted of many small states or princedoms, the princes ordered independent walls be built along state borders to protect their states. The earliest was probably built between the states of Lu and Qi around 650 BC, which later became part of the Chu State Wall.
The Qin Dynasty (221–206 BC)
Qin Shihuang (king of the State of Qin from 247–221 BC) conquered and unified the other states. Emperor Qin Shihuang ordered that the northern sections of wall on state borders, especially the walls in the northern part of China built by the states of Qin, Zhao and Yan, be joined together to form a unified line of defense against Mongol harassment from the north, the first true Great Wall. Other state border walls became obsolete in a unified China and were subsequently eroded or dismantled.
The Han Dynasty (206 BC – 220 AD)
The northern fortifications were strengthened and lengthened, with sections of wall running parallel for hundreds of kilometers and interlinking along the Inner Mongolian border.
The Han Dynasty Great Wall from the North Korea coast near Pyongyang in the east to Jade Gate Pass (Yumenguan) in the west was the longest the Great Wall has ever been at more than 8,000 km (5,000 miles). The total length included many branching walls, natural barriers, and trenches.
The Yuan Dynasty (1271–1368)
The Yuan Dynasty was the first dynasty in which the whole of China was controlled by a non-Han people, the Mongols. The Great Wall had done a good job of preserving Han China for 1,500 years. Building of the Great Wall, not surprisingly, ceased during the Yuan Dynasty, as China and Mongolia to the north were one.
The Ming Dynasty (1368–1644)
China flourished during the Ming Dynasty and its military might swell. The Great Wall was systematically rebuilt in a 100-year project to prevent further northern invasion.
Most of the remaining Great Wall was built in the Ming Dynasty, and is known as the Ming Great Wall. The Great Wall sections close to Beijing like the Badaling section and Mutianyu section were built during the Ming Dynasty.
Post-Ming History (1644–present)
A breach in the Great Wall at Shanhai Pass in 1644 by Manchu forces signaled the end of Han control in China for the last and final Chinese dynasty, the Qing Dynasty (1644–1911). It also signaled the end of construction and maintenance of the Great Wall, until the Badaling section was restored by the government of the Peoples' Republic of China, and opened to the public in 1957 as a tourist attraction.

Who Built the Great Wall and When
The Great Wall of China has a long history — more than 2,300 years. It was built in different areas by different states/dynasties to protect different territorial borders.
It's often said that the First Emperor of Qin built the Great Wall. Actually he was not the first to build it. See below:
|Dynasty||Great Wall History — Key Events|
|Zhou Dynasty: The (Pre-) Warring States Period (770–221 BC)||State overlords built state border walls.|
|The Qin Dynasty (221–207 BC)||The First Emperor of Qin linked the Great Wall sections on China's northern border.|
|The Han Dynasty (206 BC – 220 AD)||Han Wudi extended the Great Wall west to Yumen Pass and beyond.|
|The Ming Dynasty (1368–1644)||Hero General Qi Jiguang rebuilt the Great Wall around Beijing.|
Why the Great Wall Was Built
- To prevent invasion
- To protect Silk Road trade
In the Qin Dynasty, the First Emperor of Qin inked the northern walls to prevent invasion from northern nations. In the Han Dynasty, the emperors extended the Great Wall far into today's western China to protect Silk Road trade. See Why the Great Wall Was Built.
How the Great Wall Was Built
The majestic Great Wall was built with wisdom, dedication, blood, sweat, and tears. Families were separated, and many workers died and were interred as part of the Great Wall itself.
- Workers: soldiers, peasants, rebels
- Materials: stone, soil, sand, brick
- Material delivery: by hand, rope, cart, goat

How Tall Is the Great Wall of China?
The height of the Great Wall is 5–8 meters (16–26 feet), where intact/restored. It was designed to be at least three times the height of a man. Some of the Wall was built along ridges, which make it look taller.
The Great Wall's Structure — Walls, Watchtowers, Fortresses
The Great Wall of China was not just a wall. It was an integrated military defensive system with watchtowers for surveillance, fortresses for command posts and logistics, beacon towers for communications, etc.
In the Ming Dynasty (1368–1644), the Great Wall was reconstructed to be stronger and more sophisticated, due to better construction techniques being developed.
- The wall body: The Ming Great Wall usually had battlements 1.8 meters (6 feet) high with loopholes and crenels, and parapet walls 1.2 meters (4 feet) high.
- Flanking towers: Every 500 meters or less (1,640 feet) on the Great Wall there was a flanking tower allowing defenders to shoot arrows at attackers at the face of the wall.
- Fortresses were built at important/vulnerable access points (passes), such as Shanhai Pass Fortress, Juyong Pass Fortress, and Jiayu Pass Fortress. There were many archery windows and gates on the forts. The fortress gatehouses were the strongest and most impregnable structures on the Great Wall.
