WORLD HISTORY

Detailed explanation-1: -The Great Wall of China was built over centuries by China’s emperors to protect their territory. Today, it stretches for thousands of miles along China’s historic northern border.

Detailed explanation-2: -The Great Wall safeguarded the central plain of Mainland China in history and successfully kept out invasions from various northern nomadic tribes including the Huns in the Qin and Han Dynasties, the Turks in the Sui Dynasty, the Khitan in the Song Dynasty, and the Tatar, Oirat and Jurchen in the Ming Dynasty.

Detailed explanation-3: -The Great Wall protected China’s economic development and cultural progress, safeguarding trading routes such as the Silk Road, and securing the transmission of information and transportation in northern China.

Detailed explanation-4: -It was finished in 1878 and it was meant to protect the north of the empire of China from enemy attacks. It is the longest structure humans have ever built. It is about 21, 196 kilometers long, 9.1 metres (30 feet) wide and 15 metres high. The earlier sections on the wall are made of compacted dirt and stone.

Detailed explanation-5: -Because invading armies often used cavalry, a wall provided a fairly solid impediment that was difficult to get horses across. It could also be used tactically, as in 1428, when a Chinese general was able to pin a group of invading Mongols against a section of the wall and defeat them.
