Zhou Dynasty had a long history from 1046BC to 256BC, and it mainly cut into two parts of Eastern Zhou and Western Zhou. Western Zhou lasted from 1046BC until 771BC, and the political sphere of influence it created continued well into the Eastern Zhou period for another 500 years.
The last emperor of Shang dynasty, De Xin attached great importance to the development of agriculture and productivity, and implemented social changes to make its national strength strong. In same time he kept leading war to the southeast of China to lead war to another clan which called Dong Yi and The Shang Dynasty extended its influence to the Jianghuai area. But this also cause the domestic emptiness eventually led to the collapse of the Shang Dynasty later.
The Zhou nationality was a tribe living in the Loess Plateau of northern Shaanxi during the Shang Dynasty. In the early period of the Shang Dynasty Di Xin, the Nine Hou (also called Ghost Hou), illustrateshou and Zhou Hou (Ji Chang, later named Xibo) are merged into three princes of the Shang Dynasty. The nine Hou and the Marquis were killed by King Zhou of the Shang one after another because of the incident of the nine Hou’s daughter, and Zhou Houchang was also imprisoned in Youli. Zhou Houchang was later redeemed and given the power to invade the West by Emperor Di Xin of the Shang Dynasty, known as Xibochang. Laws were enacted to control slaves, such as “no sinners, no children” and “no dead children.” To avoid further direct conflict with the Shang Dynasty, Xibochang adopted the policy of uniting friends, eliminating Western military states and friends of the Shang Dynasty, and completing the isolation of the Shang Dynasty. But King Wen died suddenly the following year and was succeeded by his son Ji Fa as King Wu of Zhou.
King Wu of Zhou wait for a long time and finally find a great chance in War of Mu Ye. When all the main army of Di Xin striked the Dong Yi in 1046BC, King Wu decided to use this chance and mass all his 40,000 army to the Mu Ye. On February 26th, Zhou’s army all ready for the war and after the King Wu had announce all the crime that Shang (Di Xin) have done, the Shang’s army in that war was form up mainly in peasant and had no more morale and defeat utterly, in this war Zhou’s army had kill 180,000 of Di Xin army. After this war, Di Xin escaped back to Zhao Ge and commit suicide which lead to the end of Dynasty Shang.
During the reign of King You, the Zhou Chamber disintegrated and collapsed. Guo was reappointed by King You of Zhou to govern the state, but he was fond of profit and corruption, and sent the seized wealth to Xiang Yi, which was widely resented by the Chinese people. Two years of earthquake, landslide and drought, the people believe that this is caused by a bad emperor.
The decision of King You to abolish the crown prince pushed Western Zhou into the abyss. King You of Zhou attacked the Kingdom of Bao and obtained Bao Si, whom he love very much. King You of Zhou removed the daughter and crown prince of Marquis Xishen and appointed Baosi and his son Bofu as crown prince, so that he could only return to the Kingdom of Xishen. Shen Hou allied with Zeng and Xirong to support Yizu, and King You of Zhou also sent an army against Xishen the following year. Finally, Shen Zeng led Xirong and Quanrong to defeat King You of Zhou which meant the end of Western Zhou.
