Parts of the Great Wall were first built by princes and overlords in the Seventh Century BC as regional border defenses when China was divided into many small states.

The Great Wall Joined

After the unification of China in the beginning of the Qin Dynasty (221-206 BC), the China's first emperor, Qin Shihuang (you must have heard of his Teracotta Army), linked the walls of the three states in the north (Qin, Zhao and Yan). This formed the first "Wan Li Chang Cheng" (ten thousand li Great Wall, li is a Chinese unit of length, 2 li = 1 km).

Great Wall History

Since then, the Great Wall was rebuilt, modified or extended throughout Chinese history for over 2,000 years by millions of Chinese people drafted in for the task. The primary purpose was always to protect the Chinese Empire from the Mongolians and other invaders. Most of the Great Wall we see today was built in the Ming Dynasty (1368-1644). In some areas, two walls built in two different dynasties can be seen running side by side.

The Great Wall is not just a wall. Other defensive works such as forts, passes and beacon towers were built along the Wall to house auxiliary soldiers, store grain and weapons, and transmit military information.

Infrastructure and Development

As a product of the clashes between agricultural and nomadic economies, the Great Wall provided protection to economic development and cultural progress. It safeguarded the trading routes such as the Silk Road, and secured transmission of information and transportation.

Tourism and Building Material!

Today the world has completely changed and a few sections of the Great Wall have become some of the greatest tourist attractions in the world. The Great Wall has lost its former function.
