Why did King Qi Hua destroy the Song Dynasty and cause the three Jin states Qin, Chu and Zhao to joi

The main reason is that the strength of the Song State at that time was not very weak, and the destruction of the Song State by the Qi State not only destroyed the strategic balance at that time, but also caused dissatisfaction among other countries.

In the early Warring States period, after the three families were divided, Zhao, Wei, and Korea were among the powerful countries, and there were Tian generations of Qi, and the pattern of the Seven Heroes of the Warring States Period was formally formed, namely: Qin, Chu, Qi, Yan, Zhao, Wei, and Korea. In addition to the Seven Heroes of the Warring States, there were also large countries such as Yue, Ba, Shu, Song, Zhongshan, and Lu.

There are still Zheng Guo, Wei Guo, Teng Guo, Zou Guo, Fei Guo and so on. It is worth noting that for all the vassal states other than the Seven Heroes of the Warring States, they were basically annexed by the Seven Heroes of the Warring States, such as the State of Qi that eliminated the State of Song.

However, the price of Qi to destroy the Song Dynasty was very heavy. In 286 BC, King Qi destroyed the Song Kingdom. Two years later, that is, in 284 BC, King Yan Zhao took Le Yi as his general, and joined Yan, Qin, Han, Zhao, and Wei to attack Qi, invade Linzi, and even under 73 cities.

King Qi fled into Ju and was killed by Chu General Naoya. As a result, because of the elimination of the Song State, the Qi State was jointly attacked by the five states of Yan, Qin, Korea, Wei, and Zhao. So, the question is, after the Qi State destroyed the Song Dynasty, it was attacked by the Five Kingdoms, why did Korea destroy Zheng and not cause the princes to crusade?

First, after the Qi State destroyed the Song Dynasty, the reason why it was attacked by the Five Kingdoms is mainly divided into the following points. First, the state of Qi was very powerful in the middle of the Warring States period, and it was on an equal footing with the state of Qin, which led to its elimination of the Song state to make the princes of the world even more fearful; The second is that the State of Qi had a grudge with the State of Yan before the elimination of the Song State, so before the Five Kingdoms invaded Qi, King Zhao of Yan actively planned to promote the emergence of the Five Kingdoms Alliance; The third is that the Song State is a big country other than the Seven Heroes of the Warring States Period, and it is also a rich land, and the annexation of the Song State by the Qi State has caused the eyes of the surrounding powers to be red and dissatisfied.

In the author's opinion, based on the above reasons, the historical event of the Five Kingdoms Expedition has successfully appeared. Correspondingly, there was no similar situation when South Korea eliminated Jeong. In the early Warring States period, during the reign of Zheng Xianggong, the war with Korea was won and lost, and the situation improved for a time.

In the fifteenth year of the Emperor's reign, Han Fa Zheng took Zheng Zhiyongqiu; In the sixteenth year of the Emperor's reign, he defeated Han Yu and lost the army; Twenty-three years of Gonggong, surrounded Han Yang Zhai. That is, the annexation of Jeongkook by South Korea is not easy and easy.

Second, when Korea was about to destroy Zheng, Zhengguo once again had civil strife. Zheng Xianggong killed his prime minister Ziyang, and Ziyang's henchmen killed Zheng Xianggong. In this regard, in the opinion of many historians, Zheng Guo's civil strife accelerated the process of its elimination by Korea.

In 375 BC, Korea finally annexed the state of Zheng. On this basis, South Korea moved its capital to Xinzheng (now the area of Xinzheng City, Henan Province). Judging from the process of South Korea's elimination of Zheng Guo, it is clear that South Korea cannot be called a strong country, that is, the reason why it was able to annex Zheng Guo was because Zheng Guo himself had civil strife.

Prior to this, Zheng Guo once sent troops to besiege Yangzhai, the capital of South Korea. Of course, throughout the Warring States period, Korea has basically been the bottom vassal state among the Seven Heroes of the Warring States Period, and it is completely inferior to the other six vassal states in terms of overall strength. Therefore, although Korea eliminated Zheng, it still could not pose much of a threat to the other vassal states of the Seven Heroes of the Warring States, which was undoubtedly completely different from the situation when Qi eliminated Song.

Because South Korea is small, it is not powerful enough to threaten other countries. The Qi State was defeated because it was relatively strong, and after the destruction of the Song Dynasty, the power would be greater and threaten other countries, so it was defeated. South Korea is a country that other countries do not pay attention to, and naturally it has not been crusaded.

Because Korea did not have a grudge with any vassal state before and after the elimination of Zheng State, and Korea's sense of existence was low, and there was not much room for development, it was not crusaded.

In the author's opinion, Korea's elimination of Zheng did not cause the other vassal states of the Warring States Seven Heroes to be blushing and dissatisfied. However, the annexation of the Song State by the Qi State aroused the strong covetousness of the surrounding powers.

I think this may be due to the fact that Korea was also relatively powerful at that time, and the other princes did not crusade in order to preserve their own strength.

Because of the maintenance of the Three Jin Alliance, it was difficult for Wei and Zhao to join forces to defeat Korea. In the context that Wei and Zhao would not easily defect, the other vassal states naturally did not dare to form an alliance to crusade against Korea. And at that time, Korea was so inconspicuous that no one would pay attention to it.

As far as Korea is concerned, before and after the elimination of Zheng State, it did not form a deep hatred with any of the vassal states of the Seven Heroes of the Warring States. Due to its location in the middle reaches of the Yellow River, Korea was surrounded by Wei in the east and north, Qin in the west, Chu in the south, and the Eastern Zhou (Luoyang), which was already weak at the time, so there was no room for development.

Because the Qi State was very powerful at that time, even stronger than the Qin State, the Qin State did not dare to attack him directly, but wanted to rely on the strength of the other five countries to continuously weaken the power of the Qi State.

This was just a strategy, because at that time, the State of Qi was far away from the State of Qin, and the strength of the State of Qi was relatively strong, and the country was rich, so the State of Qin wanted to destroy the State of Qi first, which was a big problem, so it chose the Five Kingdoms to attack Qi.

Because the Qi State at that time was already stronger than the Qin State, one mountain could not tolerate two tigers, and it was necessary to destroy the largest one before carrying out a long-distance and close attack.
