Duke Zhou of Bolangsha once again stabilized the first large-scale war ruled by the Zhou Dynasty.

In the third year after the demise of Shang Dynasty, after Zhou Wuwang's death, his son Song Ji succeeded to the throne, that is, he was king, and the Duke of Zhou assisted him to be king. The Duke of Zhou was worried that he would become a king at a young age and covet ease, so he wrote an article in "There is no escape" urging him to become a king: You should know the benefits of hard work and hard work, not just covet enjoyment. We should follow the example of several sages of Shang Dynasty and Zhou Wenwang, cherish the people and strive to govern the country. On the contrary, if you don't care about people's sufferings and indulge in extravagance, you will not have a good end. For example, he said: When Yin Zhongzong was in power, he acted cautiously. He always reflects on himself, dare not indulge in pleasure and neglect political affairs. Ancestor A has been a citizen for a long time and knows the sufferings of the people. Therefore, after he succeeded to the throne, he was able to take care of the people, and Enwei did not bully widows. From then on, Wang Tiansheng, who succeeded to the throne, craved pleasure, indulged in the world all day, didn't know the hardships of farming, didn't pay attention to the king's labor, and his national strength gradually declined. He earnestly warned Wang Cheng to be a successful monarch, to be a good corporal like King Wen, and to manage the country well.

However, King Wu's younger brother, Duke Ji Dan of Zhou, acted as the king, which caused an uproar. Guan Shu, the second brother of King Wu, always wanted to succeed to the throne, and was extremely dissatisfied with Regent Zhou Gongdan. Not only did he spread rumors that Duke Zhou was a "bad boy", but he also incited other younger brothers of King Wu to openly oppose Duke Zhou. Guan Shu and Cai Shu actually encouraged Wu Genglu, the monarch of the old Shang Dynasty, to rise up against Ji Dan in an attempt to seize power. Correspondingly, there are dozens of countries in the East, such as Xu, Yan, Huai and Yi, which have good relations with Yin merchants. This was an extremely heavy blow to the newly established Zhou Dynasty. If the rebellion is not quelled, the achievements established by the ancestors of the Zhou Dynasty after decades of operation will be destroyed. At this time, the Zhou royal family was in a state of turmoil.

He first persuaded Jiang Taigong and Zhao Gong to maintain internal unity. He said:' The reason why I don't avoid difficulties is that I am afraid that the world will betray the Zhou Dynasty. Or I don't want it? Back to King Tai, King Ji and King Wen. The king worked hard for a long time, and now he has achieved something. Wu left us prematurely and the king was so young. I did this to realize Zhou Wang, Cai Chao and Zhou Gongdan. He publicly showed his attitude towards Jiang Ziya and other introverted officials, and he would definitely return the power to the king. On the one hand, actively take measures to conquer the east and start counterinsurgency.

In order to unify his thoughts and carry out the crusade smoothly, the Duke of Zhou issued a proclamation of "Dahao", expounding the necessity and significance of counterinsurgency, which not only won the silent recognition of the Yin people who did not want to fight again, but also made many vassal States stand on the side of the Duke of Zhou.

With everyone's support, in the second year, the Duke of Zhou crusaded against the rebellion of Guan, Cai and Wu Geng. Before going out for divination, Duke Zhou said to his courtiers, "The prosperity of our Zhou Xiaoguo is a godsend and the result of fate. For this expedition, I once again predict that God will help us. This is the majesty shown by God, and no one can disobey it. "You should obey God's will and help Zhou accomplish this great cause!" Hearing this, the courtiers United. After the propaganda and mobilization of the Duke of Zhou, the Duke of Zhou organized a crusade army, became the commander-in-chief and marched eastward.

Zhou is a very hard war, and it is a continuation of Zhou War. The war lasted for three years. He defeated Wu Geng and his troops, and Wu Geng was killed. At the same time, the duke of Zhou divided his forces and killed the defenders all the way. He soon wiped out the armed forces, occupied cities and killed them. Then, Zhou Jun occupied Cai Shu's residence, captured Cai Shu and imprisoned him in Guoling. Uncle Cai's son

After the crusade to pacify Guan and Cai, Duke Zhou intended to expand the crusade and destroy other rebels in one fell swoop. The Duke of Zhou originally planned to attack Oman eastward. Oman is the place where the main rebels in the east are located, that is, the place where the' great powers' live. Xin Gongjia, minister of the Zhou Dynasty, suggested:' It is difficult to attack a big country, but it is easy to attack a small country. Instead of attacking small countries, it is better to isolate big countries first.' Duke Zhou adopted his suggestion, so he changed his plan and decided to attack Jiuyi between Huai and Si first, so he sent troops to attack Jiuyi in the southeast. The strength of the small country in September 11th is not strong. Under Zhou Jun's powerful offensive, September 1 was losing ground. However, due to the long-term battle with Shang Dynasty before Jiuyi, although the army was small, its combat effectiveness was comparable and it was very familiar with local geography. Teacher Zhou's chariot is inconvenient to move, and many of his soldiers are not acclimatized. So the battle with Jiuyi was very hard, but after constant fighting, Jiuyi was finally conquered. The victory of the Eastern Expedition of the Zhou Dynasty also extended the ruling area of the Zhou Dynasty to the eastern coastal areas.

How to rule the conquered areas is a big problem after the victory of the war. Rebellion in Chouzhou and Huaiyi in Wu Geng shows that the old clan leaders can no longer be used in important areas, but must be distributed to the most reliable members of the Zhou royal family. This has something to do with the difference between Bao and Bao. In order to completely eliminate the hidden dangers of the remnants of the Shang Dynasty to the Zhou Dynasty, Duke Zhou built Luoyi on the north bank of Luoshui as the eastern capital of the Zhou Dynasty to strengthen his rule over the East. Duke Zhou named his brother Kang Shu as the central region under the rule of Shang Dynasty, with Hajj as the capital and Guo Wei as Wei Hou. Stationed in the old commercial market, managing the adherents of Shang Dynasty there. He belongs to seven Yin families: Shi Tao, Shishi, Fan Shi, Chishi, Fan Shi, Hongshi and Zhong Kui, most of whom have certain handicraft expertise. The fief in Kang Shu was not only large in area, but also had eight divisions to prevent the Yin people from resisting again.

Duke Zhou sealed his eldest son, Bo Qin, in the state of Lu and established the state of Lu. Jiang Taigong, formerly known as Qihou, is the capital of Britain. This time, Jiang Taigong made great efforts to put down the rebellion and had a very large fief, "east to the sea, west to the river, south to Muling, north to Wudi", and established Qi.

Zhou's namesake was sealed in Yan. The eldest son was sealed after he rose up, and the capital was in Kyrgyzstan. Yan is a barrier facing the northeast. In addition, the Tang and Shu Dynasties were sealed in the previous summer, and the State of Jin was established; Zhou Wang's younger brother Wei Zi was also enfeoffed for his rebellion against Zhou Wang and Wu Geng, and established the Song State in Shangqiu. Ji Dan has also divided countries with different surnames. According to records, since the founding of the People's Republic of China in July1,there are 53 people named Ji living alone. Brothers, heroes and nobles of the Zhou Dynasty in Ji Dan were placed in various important places throughout the country, which made the Zhou royal family in a security barrier. In addition, the vassal states also allocated some land to the doctors in China, which was called fiefs. Since then, Zhou's control over the lower reaches of the Yellow River has been relatively stable. Duke Zhou not only established a huge state institution, but also established a whole set of rites and music system.

The Eastern Expedition of the Zhou Dynasty played an important role in the founding history of the Western Zhou Dynasty. This is the biggest military action since King Wu was conquered. It suppressed the rebellion of the residual aristocratic forces in Shang Dynasty, played a key role in the consolidation and development of the rule of Zhou Dynasty, and had a far-reaching impact on the development of China's history. So this incident was an important turning point in the Zhou Dynasty.
