Why didn't the State of Qin support the State of Jin when the three clans were divided into Jin?

"Three clans divided Jin" refers to the event that Jin was divided up by Han, Zhao and Wei at the end of the Spring and Autumn Period in China. Historically, the "three divisions of Jin" was regarded as a watershed in the late Spring and Autumn Period and the early Warring States Period. Sima Guang listed it as the opening work of Zi Tong Zhi Jian. According to historical records such as The Warring States Policy and Zuo Zhuan, in 403 BC, King Wei Lie of Zhou made Han Qian, Evonne and Wei Si governors. In 376 BC, Han, Zhao and Wei abandoned Jin and moved to Duanshi (now Qinshui County, Jincheng City). Divide the rest of the land in Jinfu. Therefore, Han, Zhao and Wei are also collectively called "Sanjin". During the Spring and Autumn Period, the relationship between Qin and Jin was relatively good, that is, there was a saying that Qin and Jin were good. Then, the question is, why didn't Qin support Jin when the three tribes were divided into Jin?

one

First of all, during the Spring and Autumn Period, the relationship between Qin and Jin was very good. As far as good things are concerned, Qin Miaogong first married his daughter, and later Qin Miaogong married his daughter to Jin Huaigong (his grandson, son of Jin). After Qin Xiangong, the State of Qin not only sent troops to help Zhong Er, the son of the State of Qin, return to China to fight for a position, but also sent five women to Zhong Er, including some nieces. Therefore, the frequent and intensive marriages between Qin Jin were called "the goodness of Qin and Jin" by later generations. However, as far as Qin State and Jin State are concerned, although each has its own strengths as Qin Jin, after Jin Wengong dominated the Central Plains, the relationship between Qin State and Jin State gradually broke down, and then many wars broke out.

So obviously, when Wei Zhaohan was divided into Jin, an important reason for Qin's apathy was that wars broke out between Qin Jin many times, which led to poor relations. For example, in the Battle of Kan, the army of the State of Jin hit the army of the State of Qin hard. After the Battle of Kans, the wars of meandering, pumice and horse tunnel broke out between Qin Jin. In the long-term contest, Qin would like to see Jin divided into three. Furthermore, it is obviously in the interests of Qin to divide the State of Jin into three vassal states: Wei, Han and Zhao. From the point of view of Qin State, the powerful Jin State in the Spring and Autumn Period has been suppressing itself, which has caused Qin State to be unable to expand to the Central Plains for a long time.

In the historical stage of the Spring and Autumn Period and the Warring States Period, first-class talents and advanced technology and culture are often located in the Central Plains. But as far as Qin State is concerned, because of the existence of Jin State, it has been unable to expand to the Central Plains for a long time. To this end, many wars broke out between Qin Jin, but the result was more defeat than victory. Therefore, the division of the State of Jin into three obviously increased the possibility of the State of Qin defeating Sanjin. On this basis, the State of Qin was naturally unwilling to rescue the State of Jin. In other words, if the State of Qin helps the State of Jin, which leads to the fact that the State of Jin is not divided into three vassal states and ensures the continuity of the State of Jin, then it means that the State of Qin probably has no future. Moreover, even if the Qin State still carried out Shang Yang's political reform, it would be difficult to defeat the powerful Jin State.

Finally, according to historical records such as The Warring States Policy and Zuo Zhuan, in 403 BC, Han, Zhao and Wei sent envoys to Luoyi to see King Zhou Weilie, asking the Zhou Emperor to make them princes. King Wei Lie of Zhou thinks it's no use denying it. It is better to conform to the situation and formally establish three princes. As we all know, in the early Spring and Autumn Period and the Warring States Period, the Zhou royal family still had a certain appeal. As a result, because the Third Division of Jin was recognized and recognized by the Zhou Emperor, the State of Qin sent troops to support the State of Jin, and it was also an unknown division.

In other words, if the Zhou royal family calls on the world governors to attack Wei, Zhao and Han, Qin will probably take the opportunity to make moves, thus gaining certain benefits in the division of Jin by the three clans. But without the call of the Zhou emperor, Qin naturally could not sing, so he watched Wei, Han and Zhao become the seven heroes of the Warring States.
