When was Great Wall of China done built?

Who built the Great Wall? There are many answers. Some say Emperor Qin Shihuang. Some say ordinary working people of ancient China, and some say that it was slaves who built the wall. This is not an easy question to answer, just like the wall was not easy to build.

Experts have given us the most credible answer. As early as the Warring States Periods (476 BC - 221 BC), the ruling powers began to build walls as a defense against the northern nomadic tribes and other potential enemies. The state of Chu (11th Century BC-223BC) was the first to build a wall, followed by the Qi, Yan, Wei, Zhao and Qin. After Emperor Qin Shihuang unified the six states, he ordered General Meng Tian to connect the existing walls and to extend them further as a front line defense against possible invasion. Thus the Great Wall was formed. It extended from Lintao (present Lintao County in Dingxi City in Gansu Province) in the west and ended at Liaodong (present the eastern and southern parts of Liaoning Province) in the east. It was called "Wan Li Chang Cheng" (The Long Wall of 10,000 Li).
