First of all, the enfeoffment system laid a curse. In order to maintain his authoritative rule, Zhou implemented a system of enfeoffment throughout the country, requiring governors of various countries to pay tribute regularly. And when Zhou Tianzi is in danger, he should come to protect him in time. Bonfires are used to contact other vassal States. Zhou thinks he is self-righteous, thinking that he can be safe and sound if he holds the state power in his own hands, but he doesn't know that the enfeoffment system laid the groundwork for the later national division.
The Western Zhou Dynasty was destroyed because it was too corrupt and the hierarchy was too strict. This opened the timeline of the Eastern Zhou Dynasty, which was divided into the Spring and Autumn Period and the Warring States Period. In the early Spring and Autumn Period, ideas flourished and a hundred schools of thought contended. In order to pass on their ideas, many thinkers have lobbied the rulers of various countries and publicized themselves. Without the control of the Zhou emperor, the vassal States became more and more rampant and powerful, which laid the groundwork for the struggle for power and profit during the Warring States period.
During the Spring and Autumn Period when the Qin Dynasty rose, Qi and Chu were the most prosperous countries. The rulers respectively chose their most satisfactory ideas, ruled the whole country, and had the idea of starting external expansion. At the end of the Spring and Autumn Period, the separatist melee intensified, which was beyond the control of thinkers. Thus the Warring States period began. During the Warring States period, there were seven most powerful countries, called the Seven Heroes of the Warring States Period.
In the early days, Qin was only a small country, and the rulers attached importance to legalism, so the country flourished. Under the strict rule of law and discipline, the people not only abide by the law, but also make the country stronger and stronger. Qin Shihuang had the idea of unifying the whole country at the end of the Warring States Period, and finally successfully established a unified Central Plains regime, which was also the first feudal dynasty in China history-the Qin Dynasty. It can be seen that in the Zhou Dynasty, legalist thought was very suitable for the chaotic national conditions at that time, and Li Si and Han Fei were famous representatives of legalist thought. However, the Qin Dynasty became a legalist and lost a legalist. Its downfall was also due to the harsh legalist ideology.
