In the 11th century BC, King Wu of Zhou led a large army to attack the King of Shang, and the two sides fought fiercely at the Battle of Muye, which resulted in the Shang army turning against each other. Knowing that the end had come, the king ascended the deer platform, dressed in a magnificent jade robe, and then set himself on fire. After that, the Zhou army rushed to Lutai, and King Wu of Zhou beheaded the head of the King of Zhou, and then hung it on a white flag pole to show the public. Although the Shang Dynasty perished, but those Shang royal families still existed, what was their end?
After all, the Shang Dynasty ruled for five or six hundred years, and its influence far exceeded that of the newly established Zhou Dynasty. Therefore, after the fall of the Shang Dynasty, King Wu of Zhou did not wantonly massacre the Shang royal family, but adopted a policy of Huairou. When King Wu of Zhou divided the princes, he also crowned Wu Geng, the son of King Huan, and let him manage the old land of Yin Shang, "in order to continue Yin's worship and make the practice of Pan Geng's government". This decision was correct, "Yin Min Da Yue".
At the same time, King Wu of Zhou was worried that Wu Geng had the idea of restoring the country, so he divided three princely states near the old land of Yin Shang, which were managed by his three younger brothers, namely Guan Shuxian, Cai Shudu, and Huo Shu, known in history as the "Three Prisons". However, three years later, King Wu of Zhou fell ill and died, and Zhou Gongdan assisted the young King Cheng of Zhou, which caused dissatisfaction among Guan Shuxian and others. Wu Geng also saw this as an opportunity, so he joined forces with the "Three Prisons" to launch a rebellion.
Zhou Gongdan led an army on the Eastern Expedition, which eventually put down the rebellion, and Wu Geng was killed in the process of fleeing. Although Wu Geng died, there was still a royal family in the Shang Dynasty, and they were the two brothers of King Huan, namely Wei Zi Qi and Wei Zhongyan. In the late Shang Dynasty, the Qi brothers fled the Shang Dynasty and defected to the Zhou Dynasty. After the fall of the Shang Dynasty, King Wu of Zhou restored the two men to their original titles. During the Wu Geng Rebellion, Wei Ziqi did not participate in the rebellion, so he gained the trust of the Zhou royal family.
After Wu Geng was killed, Zhou Gongdan, in the name of King Cheng of Zhou, sent his son to the Song Dynasty, "to continue the Empress Yin", that is, the State of Song. After Wei Ziqi's death, his younger brother became the monarch, and his descendants ruled the Song kingdom. Although the Song kingdom was not strong, it had the highest title among the kingdoms, and was a duke of the fifth rank. It was not until the Warring States period that the Song state was destroyed by the State of Qi, the time is 286 BC, and the existence time is about 800 years.
In addition to the Qi brothers and Wu Geng, there was a very famous member of the royal family in the Shang Dynasty, who was Jizi. In the last years of the Shang Dynasty, there were three sages, namely Bigan, Jizi, and Weizi Qi, known in history as the "Three Rens of the End of Yin". Jizi was of high rank, he was the uncle of the King of Shang, and held important positions in the Shang Dynasty. Miko had repeatedly advised the King of Qiu, but instead of adopting it, he was persecuted by the King of Lu, resulting in him being imprisoned by the King of Lu.
After King Wu of Zhou entered the imperial court, in order to appease the Yin merchants, he took a series of measures, including the release of Jizi and the "summoning of the gong to release the prisoner of Jizi". However, Miko did not see King Wu of Zhou, but chose to flee, and for a time went into hiding. After King Wu of Zhou found Jizi, he asked him for advice on the way to govern the country, and Jizi explained the "Hongfan Nine Domains" to King Wu of Zhou, which won the praise of King Wu of Zhou. Later, King Wu of Zhou also divided the seals, "sealing the Jizi in Korea".
Miko's regime was known as "Miko Joseon", and under his rule, the area was developed, "Miko taught the silkworm with ritual righteousness, and also made the Eight-Point Religion". According to records, There were 41 monarchs in Jizi Joseon until the 1st century BC, that is, in the early years of the Western Han Dynasty. In other words, Miko and his descendants have ruled this land for nearly a thousand years!
