At the time of the founding of the Western Zhou Dynasty, the sphere of influence was not large, but the hometown of the Zhou State plus the Gyeonggi region of the old Shang, that is, the area along the middle and lower reaches of the Weishui River and the middle reaches of the Yellow River. The vast expanse of land in the lower reaches of the Yellow River was still in the hands of the powerful Dongyi clique, not to mention the distant Huai River and Jianghan. The remnants of the old Shang stubborn forces roamed in all directions and constantly harassed the Western Zhou forces, and the attitude of the princes of the world towards the new dynasty regime was not gloomy, and the security environment of the Western Zhou Dynasty was still not optimistic.

Based on this situation, the ruling group of the Western Zhou Dynasty carried out the first great partition; The first big seal adopted a defensive strategic thinking, and the division was carried out around a center and two basic points.

One of the centers is the Gyeonggi land of the old merchants.

King Wu divided Gyeonggi into several regions, and divided the northern region into Wu Geng, and this feudal country was called "Shao"; King Wu also migrated some of the Yin people of Chaoge with Wu Geng.

King Wu gave the Wendi southwest of Gyeonggi to the great priest Su Xinsheng; The central and southeastern parts were given to Wang Zixian, Wang Zidu, and Prince Du, and the State of Guan, Cai, and Huo were established. These three countries are known as the "Three Prisons" and play the function of monitoring and containing the Shao State.

The two basic points are the east and the west.

Now Xingyang, Henan is the east gate of the Western Zhou Dynasty, and Baoji, Shaanxi is the west gate, and King Wu divided his two uncles Uncle Yu and Yu Zhong into two places respectively, called Dongyu and Xiyu.

King Wu took back Weizi's fief and re-sealed him to Shangqiu, the former capital of Yin Shang, with the country name Song (Song and Shang are synonymous). This is a very high yin move, Weizi has a very high prestige among the old Shang nobles, he is loyal to the Western Zhou Dynasty and his ambition is dead, and now King Wu has given him more fiefs than during the period of King Wu (the name "Wei" land sounds not very big), and encircling Weizi can stabilize half of the merchants.

King Wu also divided the descendants of a number of saints, such as Feng Shun's descendant Yu Manchu in Huaiyang, with the country name Chen.

King Wu's brothers, Duke Zhou, Duke Zhao, Duke Bi, Mao Bo and other heroes with different surnames, were also given land, and the old kingdom of Xia Shang, which was a vassal to the new dynasty, still retained its original country and title. At this time, the Qi, Lu, Jin, Chu, Qin, Zheng, Wei, Wu and other countries that were in shock during the Spring and Autumn Period were not born.

The Western Zhou Dynasty was divided into feudal princes, maintaining the unity and stability of the regime, rewarding meritorious heroes, and stabilizing the people's basic policies. There is a proverb in Zhou: "Under the whole world, it is not the king's land; On the shore of the land, it is not the king's minister. "The Zhou people believe that God gave birth to the people, and then ordained the Son of Heaven to protect the people's livelihood. The Son of Heaven took the place of Heaven to administer the land under heaven, and gave the land to the nobles. Therefore, the Son of Heaven is the only landlord, and the princes and princes all belong to the lords.

As long as the lord respects the people, if nothing happens (such as being destroyed), his descendants can always keep their fiefdoms. But there are no landlords in the world (except for the Son of Heaven), and the lord should have been a landlord for a long time (this is all a later story).

After the end of the partition, the Western Zhou Dynasty presented a happy and peaceful scene, and people began to erase the wounds caused by the war, and worked hard to build their homes and prepare for a new life.

However, the heavens may have thought that the historical mission of King Wu Keshang had been completed, and that any kind of work he created was a matter of inadequacy, so he took the life of King Wu in his upright prime not long after the issuance of the decree.

King Wu of Zhou, a figure known for his iron-fisted rule of the country, died and the enormous coercion on his ministers disappeared in an instant, and his successor, King Cheng of Zhou, was only a teenager. King Cheng was powerless to grasp the boundless royal power in a short period of time; Some of his uncles with ulterior motives began to prepare to seize the power of the monarch, and as a result, the largest rebellion in the history of the dynasty broke out, the Rebellion of the Three Eunuchs.
