Geographical considerations[ edit ] Topographical map of China's northern frontier area, with modern political boundaries. Manchuriaunmarked, is to the east of Inner Mongolia.
The conflict between the Chinese and the nomads, from which the need for the Great Wall arose, stemmed from differences in geography.
The 15" isohyet marks the extent of settled agriculture, dividing the fertile fields of China to the south and the semi-arid grasslands of Inner Asia to the north. Although this allowed them to expand into the lower reaches of the Yellow River valley,  such extensive waterworks on an ever-increasing scale required collective labour, something that could only be managed by some form of bureaucracy.
Walled cities grew up around the granaries for reasons of defence along with ease of administration; they kept invaders out and ensured that citizens remained within. Likewise, according to this model, walls not only enveloped cities as time went by, but also lined the borders of the feudal states and eventually the whole Chinese empire to provide protection against raids from the agrarian northern steppes.
As animal herds are migratory by nature, communities could not afford to be stationary and therefore evolved as nomads.
According to the influential Mongolist Owen Lattimore this lifestyle proved to be incompatible with the Chinese economic model. For these needs, the nomads had to turn to the settled societies to get grains, metal tools, and luxury goods, which they could not produce by themselves.
If denied trade by the settled peoples, the nomads would resort to raiding or even conquest. Mongolia to the north, Manchuria to the northeast, and Xinjiang to the northwest. The Gobi Desertwhich accounts for two-thirds of Mongolia's area, divided the main northern and southern grazing lands and pushed the pastoral nomads to the fringes of the steppe.
On the southern side Inner Mongoliathis pressure brought the nomads into contact with China. Although the Yellow River formed a theoretical natural boundary with the north, such a border so far into the steppe was difficult to maintain.
The lands south of the Yellow River—the Hetaothe Ordos Desertand the Loess Plateau —provided no natural barriers on the approach to the Wei River valley, the oft-called cradle of Chinese civilization where the ancient capital Xi'an lay.
As such, control of the Ordos remained extremely important for the rulers of China: The region's strategic importance combined with its untenability led many dynasties to place their first walls here. When Chinese state control became weak, at various points in history Manchuria fell under the control of the forest peoples of the area, including the Jurchens and the Manchus.
The most crucial route that links Manchuria and the North China Plain is a narrow coastal strip of land, wedged between the Bohai Sea and the Yan Mountainscalled the Shanhai Pass literally the "mountain and sea pass".
In addition to the Shanhai Pass, a handful of mountain passes also provide access from Manchuria into China through the Yan Mountainschief among them the Gubeikou and Xifengkou Chinese: China proper is connected to this area by the Hexi Corridora narrow string of oases bounded by the Gobi Desert to the north and the high Tibetan Plateau to the south.
Thus it was also in China's economic interest to control this stretch of land, and hence the Great Wall's western terminus is in this corridor—the Yumen Pass during Han times and the Jiayu Pass during the Ming dynasty and thereafter.
One of the first mentions of a wall built against northern invaders is found in a poem, dated from the seventh century BC, recorded in the Classic of Poetry.
The poem tells of a king, now identified as King Xuan r. Most importantly, the fall of Western Zhou redistributed power to the states that had acknowledged Zhou's nominal rulership.It’s time for a new perspective.

The history of the Great Wall of China began when fortifications built by various states during the Spring and Autumn (– BC) and Warring States periods (– BC) were connected by the first emperor of China, Qin Shi Huang, to protect his newly founded Qin dynasty (– BC) against incursions by nomads from Inner caninariojana.com walls were built of rammed earth, constructed using.
