In every era, there were sages like Yi Yin, such as Yi Yin in the Shang Dynasty and Jiang Shang in the Zhou Dynasty. It is only the choice of the sages, many times will determine the direction of the dynasty. When the sages all tacitly stood on the opposite side, the government of the Yin Shang Dynasty was in great turmoil. As the land territory of the Yin Shang Dynasty became larger and larger, the chaos of the government produced more centrifugal forces between the Fang State and the princes, the contradiction between the Yin Shang royal family and the princely States became increasingly intense, and the Yin Shang Dynasty fell apart, in the morning and night.
Tracing the root causes of this chaos may also be related to the "Ninth Chaos" of the Shang Dynasty. What is the "Ninth Chaos"? The Yin Shang Empire went through more than a dozen monarchs, and by the time of the Shang King Zhongding, the development of the entire dynasty gradually transitioned to a period of instability, that is, starting from Zhongding, the Shang Dynasty frequently moved its capital, and even more frequently launched wars against the Rong clan. What does this mean? It shows that the influence of the Yin Shang Empire on the surrounding areas has been seriously weakened.
The Yin Shang Empire implemented a succession system that combined "father-son inheritance" and "brother-to-brother and brother", unlike the Zhou people who highly respected the primogeniture inheritance system, many of the eldest sons of the Yin Shang Empire could not become the head of the country, for example, Weizi was the eldest brother of Di Xin, but did not become the monarch. The problem of this system was fine at the beginning of the founding of the country, but once in the middle and late period, due to the coveting of power, most of the sons of the kinship would fight for the throne.
During the Yin Shang Empire, there were no large-scale internal clan wars like the Xia and Zhou Dynasties, or it was related to the fact that the Yin Shang Empire did not implement a system of sub-feudalism. Most of the relatives and sons of the Yin Shang Empire served as officials in the middle of the dynasty, and the Jizi, Weizi, and Emperor Xin of the Yin Dynasty, who are the sons of the kings of the previous and subsequent dynasties, talked together in front of the court of the Heavenly Son of the Dynasty. This circumvented the complete control of the army by the sons of the kin, who could not wage a more complete rebellion. But, wouldn't that be civil unrest? Of course not.
Chaos comes from within, and this seems to be a common thing in the ancient history of the world. The rise and fall of a country often depends on the family of the person in charge of the country. If there is a problem with this family, there will be a problem in this country, and most of the civil strife in Western history has come from relatives. A good emperor needs a good tutor, Zhou Wen Zhou Wu has a good family, the emperors of the Yin Shang Empire are not so lucky, in the middle of the development of the Yin Shang Empire, there is the "Ninth Rebellion", nephews hunting down uncles and brothers against each other, etc. Have been seen during the "Ninth Dynasty".
During the "Rebellion of the Ninth Dynasty", the Ninth Dynasty monarchs successively moved from the capital to Huan, to Xiang, then to Geng, to Xing, then to Pi, and then to Xiang, and then to Xiang, during which they successively fought with Lanyi, Banfang, Qilongrong, and Danshanrong, which shows that the Rong clan in the north at that time was already quite powerful. The deterrent power of the Merchant Empire was more likely to be seriously challenged. The so-called "Rebellion of the Ninth Dynasty, the Princes of mo dynasty" is that those Fang states that submitted to the Yin Shang Empire may gradually no longer obey orders.
The Shang king Wuding had mobilized a large number of garrisons in the north of the Shang Dynasty to suppress the Dongyi tribes, and the emptiness of the northern troops led to the aryans who moved east to break through Xinjiang and occupy the Mongolian plateau, thus threatening the Central Plains. The northern nomadic Daxing disaster was later on, and the ancestors of the Zhou people, Gu Gonggong, migrated only after being harmed by the Northern Rongdi, and the newly arrived ethnic groups in Middle-earth mixed with the Rongdi tribes here, resulting in more ethnic groups. And they later merged into the Northern Di Xi Rong Southern Barbarian Eastern Yi.
Even after the Shang King Wuding Zhongxing Empire, the entire Yin Shang Empire still did not completely eliminate the threat of Rong Yi, and Wu Ding and subsequent generations of monarchs have launched large-scale wars many times, which also shows that the Yin Shang Empire has tacitly acquiesced to the development and growth of the Northern Rong and Eastern Yi since the "Ninth Rebellion". More control of the Yin Shang Empire was still in the Middle Lands area, and Dongyi became the object of conquest for the Emperors of the Yin Shang, because the East was also the birthplace of the ancestors of the Yin Shang. However, even by the time of the last monarch, King Yin, the Yin Shang Empire had not really eliminated those Fang states of Dongyi.
The later attitude of the Zhou people towards the surrounding tribes was basically influenced by the Yin Shang Empire. The name Of the Rong Di is often related to the non-I race. Those who had been attached to the Yin Shang Empire, because they were invaded by more foreign tribes, those who were powerless to resist migrated again, some to the east, some to the south, some to the north, and they also brought the Middle-earth civilization to farther away, some to Lake Baikal, some to Siberia, or to the far south. It was this great rout of control of the Yin Shang Empire that brought about subtle changes in the political and geographical landscape of East Asia.
Those Fang States and princes who were able to resist, in addition to garrisoning the border, also had doubts about the national strategy of the Yin Shang Empire, such as the ancient Gong Gong father, King Wen JiChang, etc. all went to the Yin Shang capital to protest. Gu Gong's father accused the Shang royal family of disregarding their family affection and disregarding the social order, so after moving to Zhou Yuan, they were "Shiwei Merchants". Those relatives of the Yin Shang Empire, those sages, all chose to betray the Empire without hesitation. The Yin Shang Empire, which had lost the hearts and minds of the people, was now worried about internal and external troubles.
