Historical small Bai Xie is invited. This is two problems, want to treat actual condition of Zhou Chao first, will solve again why movement of country of Chinese most dynasty does not exceed 300 years.
According to textual criticism of our country history, zhou Chao only then controlled 1100 at BC, 255 years to BC Qin Guogong enters Luo Yi, week government last a period of time 850 one's remaining years are formal and ruined. But actually cent is Zhou Chao 3 phase, royal family of times of the Eastern Zhou Dynasty already exist in name only, age and the Warring States are very different also, central Plains is the mainest fall to pieces of political power Jin Guoye, circumjacent Xiaoguo also annex dangers, do not talk to go up stable national politics system. Can say, this times still accords with Chinese dynasty 300 years roughly mensurable, only the Western Zhou Dynasty grows slightly a few.
So is the reason why?
Regard the history as layman, have some of immature view, fall without textual research of specific history data, the author thinks this is come from erupt to contradict with what cannot mediate between backward productivity at population, bear hard when land natural resources when population bear, violent change can bring about political power replace.
This kind is academic, receive it seems that be bordering on film answer couplet 3 destroy bully the balance is academic, namely population trap of Malthus talks the Englishman. Below the circumstance with limited natural resources, if cannot limit population scope, so the crisis can appear. This kind of thought, also coached inside a long time when plan of face radical homeland. . .
We know now, besides family planning, we still can wait for a way to increase resource load capacity through reforming productivity, raise the cereal breed with specific yield, new development for example, for example the large area of potato, corn is cultivated alleviated with respect to huge resource crisis.
Before Industrial Revolution, the development of productivity is very slow, but type of extremely easy however explosion increases population. For example Qin Mo is agelong chaos caused by war, the population when Han Chaojian stands is insufficient 13 million, but through Wen Jing the long preserve one's health of 2 emperor ceases, population of fierce emperor period has been broken through 36 million. The population that comes out more, how to find a place for became tremendous hidden trouble. Tang Chu, bright first, the phase that population quickness growth is at the beginning of Qing Dynasty. Xia Shangzhou can be maintained longer, I want to grow to have particular concern slower with population, at that time on the low side of human mean life, population and resource contradiction are not apparent.
The contradiction of population and land is essential contradiction. Want to solve this problem, no more than two kinds of methods, one kind is external the territory under one's control that dilate grabs exotic nation, in fact, hun, Tujue, Qidan, Mongolia, Nuuzhen a group of things with common features also is so dry; One kind is internally the territory under one's control that annex grabs people on one's own side, this kind of thing doing rises it is more easy to appear. Despot annex land, can cause social unrest, once encounter God,calamity person disaster can ignite fury.
Meanwhile, regime interior also can appear differentiation, centralized also meet with the conflict of local interest more and more apparent. Because of this China 2000 feudal society, it is almost hundred years do poineering work, the hundred years prodigal, hundred years mode that plays goes to be not taken off. In fact, the west is about the same also, do not see Roman Caesarean from beginning to end 1500, different level is immanent and actually complete it is different political power, resemble China two Chinese, two the Song Dynasty do not calculate a dynasty actually, just we am China empire on name just.
