Zhou Dynasty
The Zhou Dynasty is probably the dynasty that reigned for the longest period not only of all Chinese dynasties, but of the whole world.
The Zhou Dynasty originated from the Zhou clan whose existence stretches back into history. By the 11th Century BC, the Zhou Clan had become increasingly powerful and had extended throughout the present Shaanxi and Gansu Provinces. The Zhou Clan´s mightiness increasingly menaced the Shang Dynasty and the conflict between the two groups intensified.
At that time, the Shang Dynasty was under the rule of King Zhou. He was atrocious to his people and doted on his imperial concubine, Daji. All he did caused great rage amongst his people. The chief of the Zhou Tribe, Zhou Wenwang thought it was the right time to attack the Shang Dynasty and entrusted his son Ji Fa to fulfill his last wish. After Zhou Wenwang died, his son Ji Fa (Zhou Wuwang) succeeded him. He made full preparations for the war and killed King Zhou. Thus the Shang Dynasty ended in 1046 BC.
Later, Zhou Wuwang established the Zhou Dynasty and made Haojing (the present Chang´an County, Shaanxi Province) its capital. The Zhou Dynasty was the longest dynasty in Chinese history. It lasted for over 800 years and included the reigns of 37 emperors.

The Zhou Dynasty is divided into two periods: the Western Zhou Dynasty (11th century BC to 771 BC) and the Eastern Zhou Dynasty (770 BC – 221 BC). It is so divided because the capital cities in the Western Zhou Dynasty of Fengyi (presently in the southwest of Chang´an County, Shaanxi Province) and Haojing lie to the west of the Eastern Zhou´s capital of Luoyi (present Luoyang, Henan Province). As to the Eastern Dynasty, it is divided into the Spring and Autumn Periods (770 BC-476 BC), and the Warring States Period (476 BC – 221 BC). Each of the periods featured turbulent wars.
The achievements during the Zhou Dynasty in economy, politics, science and culture, were much more illustrious than any which occurred during the Shang Dynasty.
The Zhou began as a semi-nomadic tribe that lived to the west of the Shang kingdom. Due to their nomadic ways, they learned how to work with people of different cultures. After a time, they settled in the Wei River valley, where they became vassals of the Shang. The Zhou eventually became stronger than the Shang, and in about 1040 B.C. they defeated the Shang in warfare. They built their capital in Xi´an. Part of their success was the result of gaining the allegiance of disaffected city-states. The Shang were also weakened due to their constant warfare with people to the north.
The Chinese civilization expanded during the time of the Zhou dynasty. The massive size that the dynasty covered was too much for the Zhou leaders to handle due to the poor means of communication. Because of this, the leaders decided to appoint people to oversee each of the territories. The territories started off as walled off cities. The leader of each of the territories were the lords, each receiving the title through inheritance. Next in the hierarchy were the fighting men, followed by the peasants and the domestic slaves. Soon, these territories became more independent, eventually breaking away from the main Zhou dynasty leaders.
The Zhou society was based on agricultural production. During that time, the land of the lords was divided among the peasants to grow crops. They were divided up into three by three squares, with the eight outer squares being worked on by the peasants. The center tract of land was worked on by all eight of the peasants for the lord. The extent of this type of land distibution was unclear, but the later dynasties believed that this was the most equitable way of dealing with land distribution and use.
The Zhou adopted much of the Shang lifestyle, often importing Shang families or communities to new towns they built to utilize the knowledge of the Shang artisans. The bronze vessels of the Zhou are nearly identical with those of the Shang. The Zhou also adopted much of the Shang writing system, rituals, and administration techniques. The Zhou however, began a different form of governing, which was basically feudal. Land was given to people in elaborate ceremonies. The landowners became vassals to the king. Descent became patriarchal, from father to son, rather than from eldest brother to youngest brother as practiced by the Shang.
The Zhou, despite transporting the Shang to their cities for their skills, did not want to live directly with the Shang. Their capital was divided into two sections, one for the Zhou, that contained the imperial court, and the other half for the transported Shang. Other Zhou cities exhibit this same characteristic. However, this was the only major change in cities from the Shang Dynasty to the Zhou Dynasty. Otherwise, the houses remained the same as in the Shang Dynasty.
The Zhou also brought their religion with them. They banned human sacrifice. They practiced the cult of Heaven. The worship of sun and stars was the most important thing. Some of the popular Shang gods became incorporated into this system. They were lesser gods, and served as feudal lords to the Heaven-god.
In the year 221 BC, Qin defeated the other six states which existed during the Warring States Period and unified China. Thus, history moved forward to a new age called the Qin Dynasty.
