What is the reason why Chiyou went to war with the Yellow Emperor?

Legend has it that in ancient times, more than 4,600 years ago, Chiyou, Yan Di and Huangdi were the leaders of three tribes, and they fought with each other to solve their internal survival problems. From a macro point of view, there is no difference between justice and evil, and there is no difference between who is right and who is wrong. They all fought for the survival of themselves and their tribe.

And history is always based on "the winner is king and the loser is the enemy", and the winner can get more praise. Historically, whenever a tribe or country becomes more and more powerful, its population and area will increase from time to time. In order to meet the needs of development and deal with the problem of survival, it will gradually expand outward.

When expanding to foreign borders, there will inevitably be friction and conflict with foreign countries, and the result of the conflict is to trigger a war and seize territory from each other by force. The winner annexed a lot of territory, and the loser's territory shrank further, leading to national subjugation.

Chiyou is powerful, brave and good at fighting, and has the reputation of "God of War" among the people. He lived in the middle and lower reaches of the Yellow River, located in today's Henan, Shandong and Hebei areas. He is an outstanding leader of Jiuli tribe. The whole tribe worships the cow as a totem, and Chi You led the tribe to open up wasteland, cultivate, smelt iron, make weapons and make etiquette here, which laid a solid foundation for China's early farming culture. It is said that iron smelting technology, ritual and music culture and weapon manufacturing were all created by Chiyou. As the ultimate winner, Huangdi's greatest contribution was to defeat Chiyou and Yan Di and unify China. Therefore, it is regarded as the * * * co-owner of the Huaxia tribe.

At first, both Chiyou and Yandi were very powerful, pushing the Yellow Emperor into a small center in the middle reaches of the Yellow River. Later, with the development of the Yellow Emperor from time to time, it formed a tripartite confrontation with Chiyou and Yan. Chiyou lives in the east and in Hebei, Shandong. Emperor Yan ruled the west, about in the northwest today. The Yellow Emperor ruled the Central Plains in the middle and lower reaches of the Yellow River. In order to seize the vast territory in the lower reaches of the Yellow River, Chiyou and Yan Di first launched a great war in the Central Plains. Due to the help of many strange people in the Chiyou array, Yan Di lost his way after hiding for a while, so he fled south.

Seeing that Chiyou's power is getting stronger and stronger, the Yellow Emperor is worried that it will pose a threat to himself in the future. So, he took the initiative to separate from Emperor Yan and formed a tribal alliance, and the joint forces of the two fought a decisive battle with Chiyou's army in Jinglu area (now Zhangjiakou, Hebei). At the beginning of the campaign, the two sides were almost evenly matched, with each other winning or losing. Legend has it that both sides invited many strange people and animals to participate in the battle, and the attack and defense were quite fierce. Eventually, due to the superb skills of the Yan-Huang allied forces, Chiyou was completely annihilated in the Central Plains.
