According to historical records such as Historical Records and Warring States Policy, 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". Sanfen Jin is an event of great significance in the ancient history of China, and it is a watershed in the Spring and Autumn Period and the Warring States Period. The three clans are divided into Jin, Wei, Zhao and Han Emperors, and are called "Seven Heroes of the Warring States" together with Qi, Qin, Chu and Yan. Although these seven vassal States are called "Seven Heroes of the Warring States", the strength gap between them is very obvious. On the whole, Qin was the most powerful vassal state among the Seven Heroes of the Warring States. Then, the question is coming. Which country is the weakest among the Seven Heroes in the Warring States Period? In this regard, many people's first reaction is South Korea in Sanjin.

one

First of all, in the eyes of many people, South Korea is the weakest country among the Seven Heroes of the Warring States Period. The reason is also very simple. South Korea lacked achievements in the Warring States period, and was destroyed by Qin in 230 BC, becoming a vassal state among the six Shandong countries. However, in my opinion, Yan is the weakest of the seven heroes in the Warring States Period. On the one hand, among the six countries destroyed by Qin, although South Korea was destroyed by Qin in 230 BC, Yan persisted until 222 BC. But as far as Korea is concerned, it was destroyed by Qin after being weakened by many battles such as the Battle of Yi Que, the Battle of Jiaocheng and the Battle of Yiyang. In other words, Qin destroyed Korea after many wars, which took decades or even hundreds of years.

Accordingly, the reason why Yan State was destroyed by Qin State in 222 BC was mainly because Yan State was far from the Central Plains and was separated from Qin State by vassal states such as Sanjin. Qin was almost overwhelming in destroying Yan, and there was no great resistance. If the positions of Yan and South Korea are reversed, Yan's performance is probably not as good as that of South Korea. On the other hand, Yan's performance in the Warring States period was very weak. According to historical records, in the sixth year of Qi Xuanwang (3 14 BC), the state of Qi took advantage of the civil strife in the State of Yan, so that the famous Zhang Kuang led a hundred thousand troops to set out from the Bohai Sea, and on the 50th, he attacked and destroyed the State of Yan. Thus, before Qin destroyed the Six Kingdoms, Yan was actually destroyed by Qi once.

For Qi, it took only a few days to break the capital of Yan and basically occupied the territory of Yan. This undoubtedly reflects the weakness of Yan. Of course, under the pressure of Qin, Wei, Zhao, South Korea and other vassal States, Qi finally withdrew from Yan State and Yan State was restored. Since then, after decades of efforts, Yan recovered and led five armies to attack more than 70 cities in Qi. In this respect, I think the success of cutting Qi is based on the union of Yan, Qin, Han, Wei and Zhao. In other words, Le Yi's success in cutting Qi does not reflect the strength of Yan State. Correspondingly, in the battle of Changping and Handan, the battle of Yanzhao revealed the true strength of Yan State.

Finally, in 25 1 year BC (the fourth year of Yan), Zhao was seriously injured in the battle of Changping and the battle of Handan. In this regard, Yan sent Li Abdomen to attack Zhao, Zhao sent Lian Po to resist, Li Abdomen was beheaded, and Lian Po took the opportunity to surround the capital of Yan. Yan sent a general to make peace, and Zhao listened to the mediation of General Canal and lifted the siege of Yan. In 243 BC (the 12th year of the Prince of Yan), Zhao sent Li Mu to attack the State of Yan and occupied Wusui and Fangcheng. In 236 BC (the 19th year of Yan State Xi), Zhao Limu once again led an army to attack Yan State and capture raccoons and Yangcheng. Thus, after being badly weakened, Zhao can still easily defeat Yan State and even surround the capital of Yan State. To sum up, among the seven heroes of the Warring States, Yan was the weakest vassal state. It is precisely because of her own weakness that Yan hopes to assassinate Qin Shihuang by means of "Jing Ke stabbing Qin" to delay her own demise.
