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. 

Traditional Chinese history says that the Zhou were able to take over the Shang because the Shang had degenerated morally. Part of this belief may have been caused by the Zhou themselves, who are credited with the idea of the Mandate of Heaven. The Zhou used this idea to validate their takeover and subsequent ruling of the former Shang kingdom. The Mandate of Heaven says that Heaven, or tian, places the mandate, tianming, to rule on any family that is morally worthy of the responsibility. Also, the only way to know if the Mandate of Heaven had been removed from the ruling family was if they were overthrown. If the ruler is overthrown, then the victors had the Mandate of Heaven. 

The Zhou adopted much of the Shang lifestyle and 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, which 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. 

The Zhou Dynasty is divided into sub periods. The first is the Western Zhou, which occurs from the time of their victory over the Shang until about 771 B.C. when they were forced east by barbarians from the north. The king was killed but his son was saved and moved east where a new capital was formed in Luoyang. This began the period known as the Eastern Zhou. The Eastern Zhou is further divided into two time periods, the Spring and Autumn Period and the Warring States Period. The Spring and Autumn Period occurred from about 770-476 B.C. During this time, the Zhou emperor steadily lost power due to the realization by the feudal lords that he was not powerful and could be beaten, which had been proven by the defeat in the west. The second half, the Warring States Period, is so named because of the power struggle between the large states of China that were trying to gain control over the entire area. It lasted from about 475 - 221 B.C. 

This time period of the Warring States is considered the classical age, it was a time of great philosophers. This cultural flowering is sometimes called the One Hundred Schools Period. Confucianism, Taoism, and Legalism developed during this time. Of these three, Legalism had the most immediate effect, as it was the philosophy that the Qin, the next dynasty used as the basis of their rule. Some of the most memorable poetry and prose were also written during this time. Other advances included the writing down of the laws, an increase in market places, and a money economy. The development of iron, and tools made of iron, greatly increased agriculture and thus population exploded.

Kings of the Zhou Dynasty 

The rulers of the Zhou dynasty were titled Wang (王, literally “king”) like the Shang rulers before them. The position is normally translated into English as "king". In addition to these rulers, King Wu's immediate ancestors – Danfu, Jili, and Wen – are also referred to as "Kings of Zhou", despite having been nominal vassals of the Shang kings.

NB: Dates in Chinese history before the first year of the Gonghe Regency in 841 BC are contentious and vary by source. Those below are those published by Xia–Shang–Zhou Chronology Project and Edward L. Shaughnessy's The Absolute Absolute chronology of the Western Zhou Dynasty.
