What was the primary purpose of the Great Wall of China?

• A. To serve as a trade route
• B. To protect against invasions from northern tribes
• C. To demarcate territory
• D. To house troops permanently

Answer: (B)

The primary purpose of the Great Wall of China was to protect against invasions from northern tribes, particularly during the various dynastic periods when nomadic groups posed significant threats to Chinese settlements. This massive structure was constructed and expanded over centuries, with its origins dating back to the 7th century BC, under different dynasties, notably the Qin, Han, and Ming.

The wall functioned as a defensive fortification, integrating watchtowers, troop barracks, and signaling systems to ensure rapid communication and response to potential invasions. Its strategic positioning allowed for monitoring and controlling movement along the northern border, helping to safeguard agricultural and urban areas from raids.

While the Great Wall did play a role in demarcating territory, it was primarily a military defense mechanism. It did not serve as a trade route, although trade occurred along its peripheries, nor was it designed to house troops permanently; rather, it acted as a deterrent and provided security for the troops stationed along its length during times of conflict.
