Long Wall of Ten Thousand Li China
Known to the Chinese as the 'Long Wall of Ten Thousand Li', the formidable defensive structures built to ward off invasion of the Celestial Empire by barbarians is called the Great Wall or the Wall of China by Europeans. The principle of these extraordinary fortifications goes back to the Chunqiu period (722-481 BC) and to the Warring States period (453-221 BC).The construction of certain walls can be explained by feudal conflicts, such as that built by the Wei in 408 BC to defend their kingdom against the Qin. Its vestiges, conserved in the centre of China, antedate by many years the walls built by the Kingdoms of Qin, Zhao and Yan against the northern barbarians around 300 BC. Beginning in 220 BC, Qin Shi Huang, the founder of the Empire of the Ten Thousand Generations, undertook to restore and link up the separate sections of the Great Wall which had been built in the 3rd century BC, or perhaps even earlier, and which stretched from the region of the Ordos to Manchuria. ...
