In 403 BC, King Weilie of the Eastern Zhou Dynasty appointed three governors, namely Han, Zhao and Wei, and the situation of seven heroes in the Warring States was formally formed. From 140 princes in the early Spring and Autumn Period, after more than 360 years of merger, only more than 20 princes remained in the early Warring States Period.
Among them, there is Qin State in the west, Qi State in the east, Three Jin States in the Central Plains (Zhao, Wei and Han), Chu State in the south and Yan State in the north, with the strongest strength. History is called "Seven Heroes of the Warring States". The war of annexation reduced the number of vassals, expanded the territory of the victors, increased the population and concentrated wealth. Originally scattered in the hands of various governors, the wealth of land and population was concentrated in the hands of a few governors.
The world has been integrated from hundreds of small countries into more than a dozen large entity countries, and the original strategic buffer space no longer exists, so big countries have to face the pattern of direct and brutal competition. The concentration of resources makes the scale and intensity of wars between countries rise sharply.
How to survive the fierce attack and competition among each other, and Qiang Bing, a rich country, has become the primary consideration of policy makers in various countries. Under the total demand of this era, a series of political reforms were launched in time, and the curtain of the Warring States period was also opened.
According to statistics, there were 230 wars from the first year of Zhou Yuanwang (475 BC) to the twenty-sixth year of Qin (22 BC1year). When the war broke out, both sides dispatched tens of thousands to hundreds of thousands of people at every turn. At the end of the Western Han Dynasty, Liu Xiang compiled all kinds of historical materials into a book called The Warring States Policy. Since then, this historical stage has been called the Warring States Period.
Extended data:
Among the Seven Heroes in the Warring States Period, the strongest is Qin.
Mainly because of the success of Shang Yang's political reform. In 356 BC, Shang Yang began to reform with the support of Qin Xiaogong.
The law provides that:
1, the state recognizes that land is private and allows free trading.
2. Those who reward farming and produce more grain and cloth can be exempted from corvee.
3, according to the size of the military, awarded a title and Tian Zhai, abolished the old aristocratic privileges without military.
4, the establishment of county system, by the monarch directly sent officials for governance. After Shang Yang's political reform, Qin's economy developed, and the combat effectiveness of the army was constantly strengthened, and it developed into the most prosperous feudal country in the late feudal period.
