At the end of the Spring and Autumn Period, the power of the Zhou royal family was further weakened, and the Jin state at that time had become an unmatched hegemon of the princely states by holding high the banner of honoring the king, although the Jin state with strong military strength and vast and rich territory also showed its fatal weakness.
The successive monarchs of the Jin Dynasty who rose in the Central Plains also followed the Etiquette Of the Zhou Dynasty, and the sub-feudal system made the Jin clan too powerful. In the later period, the jin monarch suppressed the clan forces in order to strengthen the centralization of power. During the Jin Dynasty, the clan power was weakened, and in order to run the state apparatus, the Jin Wengong formulated the policy of six secretaries and used the Qing dafu to form a "small cabinet" to govern the country. However, with the passage of time, The strength of Dr. Qing gradually surpassed that of the Duke of Jin.
By the time of the Jin Dynasty, there were still four remaining families of the Jin Dynasty, namely the Zhi clan, the Zhao clan, the Han clan, and the Wei clan. Of the four families, the Zhi clan was the most powerful. Due to the infighting among various families for many years, the national strength was greatly damaged, and it was impossible to compete for hegemony externally, and when the Jin Dynasty was out of the gong, the Zhi clan patriarch Bo Yao ruled the Jin state, and the Jin state, which had suffered a great loss in national strength in successive years, increased its national strength significantly under the governance of Zhi Bo Yao. However, because of this, Zhi Boyao's ambitions swelled, hoping to weaken the Three Families of Zhao, Wei, and Han to monopolize the government, so he suppressed the three families under the pretext of being a rich country and a strong army, but was unexpectedly eliminated by the three families of Zhao, Wei, and Han, and the Zhi clan was not only slaughtered by the Zhao, Wei, and Han families overnight, but also divided up all the territories that originally belonged to the Zhi clan, so that han Wei Zhao's strength was further strengthened, and the deeply disturbed Jin Dynasty borrowed troops from Qi and Lu to attack the Zhao Wei and Han families, in an attempt to regain the royal rights. Unexpectedly, the three families jointly attacked Jin Chugong, and Jin Chugong was defeated, forced to flee, and eventually fell ill and died on the road. The three families also established the Duke of Jin as the new monarch.
The Duke of Jin was a puppet, and in 434 BC, the Duke of Jin died and was succeeded by the Duke of Jin. During the Jin Dynasty, the territory belonging to the jin monarch was only the two cities of Dai and Quwo, and as a monarch of a country, he lost all his majesty, lived in fear every day, looked at the woman he liked, and could only go quietly at night, and as a result, he was stolen and killed. After the Duke of Jin You, the enthronement was the Duke of Jin Lie.
During the reign of duke Lie of Jin, in 403 BC, King Weilie of Zhou ordered the three families of Han, Zhao, and Wei to be princes and established side by side with the Jin state, but although the titles of the monarchs of the Jin state were higher than those of the Han, Zhao, and Wei families. However, at this time, the Jin state was actually controlled by the State of Wei. In 389 BC, The Duke of Lie died and The Duke of Filial Piety took the throne.
During the Jin Dynasty, even the last two cities were divided, and no one was willing to accept the three families of the former monarch. In this way, Jin Xiaogong was kicked around like a leather ball by the Three Families of Han Zhao and Wei, and in the twentieth year of Filial Piety (369 BC), Zhao Moved Jinjun to Tunliu, and later sealed Jinjun to Duanshi. After the death of Duke Xiao of Jin, He was appointed to the throne.
After the Succession of duke Jing of Jin, in 349 BC, the State of Zhao captured the last fiefdom of the Jin monarch, Duanshi, and moved the Duke of Jin jing to Tunliu, which was controlled by Korea, and the Korean monarch Han Zhaohou ostensibly warmly greeted the Duke of Jinjing, and secretly instigated the concubines of the Duke of Jinjing to assassinate the Duke of Jinjing, and since then the State of Jin has completely disappeared from the territory of the Spring and Autumn Period, and history has entered the Warring States period.
Due to the weakening of the power of the clan feudal monarchs, the Jin state established six secretaries to strengthen the centralization of the monarchy. The monarchical centralization was originally a relatively advanced political system compared to the feudal system at that time. Unfortunately, the level of economy, culture and productivity at that time could not be implemented.
Eventually, after the monarch was displaced, the later Emperor Xian of Han was also due to the eunuchs and foreign relatives interfering in the government and power, resulting in emperor Xian of Han having the same experience, but the character of Han Zhaohou was much worse than that of Cao Cao.
