Wall Building during the Ming Dynasty
Despite its long history, the Great Wall of China as it is exists today was constructed mainly during the mighty Ming dynasty (1368-1644). Like the Mongols, the early Ming rulers had little interest in building border fortifications, and wall building was limited before the late 15th century.
In 1421, the Ming emperor Yongle proclaimed China’s new capital, Beijing, on the site of the former Mongol city of Dadu. Under the strong hand of the Ming rulers, Chinese culture flourished, and the period saw an immense amount of construction in addition to the Great Wall, including bridges, temples and pagodas.
The construction of the Great Wall as it is known today began around 1474. After an initial phase of territorial expansion, Ming rulers took a largely defensive stance, and their reformation and extension of the Great Wall was key to this strategy.
The Ming wall extended from the Yalu River in Liaoning Province to the eastern bank of the Taolai River in Gansu Province, and winded its way from east to west through today’s Liaoning, Hebei, Tianjin, Beijing, Inner Mongolia, Shanxi, Shaanxi, Ningxia and Gansu. Starting west of Juyong Pass, the Great Wall was split into south and north lines, respectively named the Inner and Outer walls.
Strategic fortresses (passes) and gates were placed along the wall; the Juyong, Daoma and Zijing passes, closest to Beijing, were named the Three Inner Passes, while further west were Yanmen, Ningwu and Piantou, the Three Outer Passes. All six passes were heavily garrisoned during the Ming period and considered vital to the defense of the capital.
