Home / Great Wall / History / Qin Dynasty. The Great Wall of the Qin Dynasty (221BC-207 BC) was built during the reign of Emperor Qin Shi Huang, along the country's northern border to prevent the invasion of Huns. In 221BC, Emperor Qin Shi Huang unified China for the first time after annexing six states.
The Great Wall of China was not built all at one time. In 7th and 8th century BC, battles happened frequently among the states of the Spring-Autumn and Warring States dynasty and in order to defend themselves they began to built walls and towers on the borders. It was the state Chu who first built the wall.
