In BC, after defeating other states and unifying the Central Plain, Emperor Qin Shihuang ordered General Mengtian to connect the existing walls and extend them further as a front line to defend against possible invasion from northern nomadic tribes. This took more than 10 years.

Therefore, a continuous Great Wall was made for the first time about 2, years ago. In addition, there were also four periods of repair and construction during the reign of Emperor Wu of the Han Dynasty.

The first time and second times were both in BC to prepare for war with the northern Huns and to guarantee the safety of the Silk Road. The third time was during — BC, and the last time was — BC.

They are in bits, and very few of them look like the glorious creation to which tourists go. Tame sections give way to wild ones — crumbling, overgrown, barred to walkers — and wild ones vanish into gaps made by roads and reservoirs. In many places, the Wall doubles, triples even quadruples itself.

And all of these bits overlap each other in time. The sections you see around Beijing have ancient precedents, some of which run directly beneath the Wall. And these divided sections are as nothing compared to other walls of earth, which run westward in parallel lines and scattered segments.

Construction to create the current 13, miles of wall continued, on and off, for more than two millennia. Much of what remains was built during the Ming Dynasty. While intended to keep out foreign invaders, Genghis Khan demonstrated how even a wall as great as this had a flaw. He marched his Mongol horde around one of the sides. Sections of the Great Wall owe their longevity to a rather unusual mortar — glutinous rice flour.

And there is much more to the Wall than walls or banks: fortresses, barracks, guard-towers and beacon-towers stalk the main lines of the Wall in a sort of stretched-out halo. The threat then was from the Xiongnu, who possibly became the ancestors of the Huns.
