The Northern Line at the Great Wall of China Mapped by Archaeologists
Archaeologists have carried out the first systematic survey of a section of the Great Wall, previously thought to be constructed to defend against Genghis Khan.
The Northern Line (also called Genghis Khan’s Wall) is a section of the Great Wall of China, that runs across the Mongolian Steppe in Mongolia and some sections in Russia and China. The wall spans 737 km and was built in the medieval period between the 11th-13th century AD.
The study, published in the journal Antiquity has suggested that the wall was constructed to not only prevent nomadic raids, but also served as a mechanism to monitor and control the movements of nomadic populations and their supporting herds.
Archaeologists examining the wall have revealed that instead of defence, the wall was aimed at expanding the influence of the Khitan-Liao Empire, one of the Imperial dynasties in the region that sought control over the nomads living along their northern territory.
