Western Zhou(西周):
In Chinese, it is pronounced as: xī zhōu，Written as:

The Western Zhou was an important dynasty in Chinese history, spanning from around 1046 BCE to 771 BCE. It marked the early phase of the Zhou Dynasty, with its capital at Haojing, which is today’s Chang’an District in Xi’an, Shaanxi Province.
The founder of the Western Zhou was King Wu of Zhou, whose given name was Ji Fa. In 1046 BCE, he united the feudal lords and defeated the Shang Dynasty at the Battle of Muye, overthrowing King Zhou of Shang and establishing the Zhou Dynasty. After King Wu’s death, his brother, the Duke of Zhou, assisted the young King Cheng in stabilizing the state and laying the political foundation for the Western Zhou.
The Western Zhou implemented a Feudal System, distributing land and people to members of the royal family and meritorious subjects, thus establishing them as feudal lords. This system helped to consolidate rule and also promoted local development.
During the Western Zhou, agricultural technology made significant advances and the use of iron tools began to spread, boosting agricultural production. The Western Zhou also emphasized the culture of Rites and Music, with its system becoming an important part of social norms and political structure, having a profound influence.
In the late Western Zhou, internal political corruption and invasions by the nomadic tribe, the Quanrong, gradually weakened the state. King You of Zhou attempted a revival, but with limited success. In 771 BCE, in an attempt to please his favorite concubine Bao Si with the “Teasing the Dukes with Beacon” ploy, he provoked an attack by the Quanrong, leading to the fall of Haojing and the end of the Western Zhou.
The Western Zhou was a crucial stage in the development of early Chinese civilization. Its political system, culture of Rites and Music, and Patriarchal Clan System had a deep impact on subsequent Chinese society. The fall of the Western Zhou marked the transition into the Eastern Zhou and the start of the tumultuous Spring and Autumn and Warring States periods.
