King Wu of Zhou in the context of "Dongyi"

The Western Zhou (Chinese: 西周; pinyin: Xīzhōu; c. 1046 – 771 BC) was a period of Chinese history corresponding roughly to the first half of the Zhou dynasty. It began when King Wu of Zhou overthrew the Shang dynasty at the Battle of Muye and ended in 771 BC when Quanrong pastoralists sacked the Zhou capital at Haojing and killed King You of Zhou. The "Western" label for the period refers to the location of the Zhou royal capitals, which were clustered in the Wei River valley near present-day Xi'an.

The early Zhou state was ascendant for about 75 years; thereafter, it gradually lost power. The former lands of the Shang were divided into hereditary fiefs that became increasingly independent of the Zhou king over time. The Zhou court was driven out of the Wei River valley in 771 BC: this marked the beginning of the Eastern Zhou period, wherein political power was wielded in actuality by the king's nominal vassals.

The Chinese ritual music is the music used in the rituals of traditional Chinese religion. It is also described as the ritual and music system (Chinese: 礼乐制度; pinyin: Lǐ yuè zhìdù) because of its perceived importance in Chinese culture since the Zhou dynasty— particularly within Confucianism—to establishing and maintaining social order. Together with the patriarchal system, it constituted the social system of the entire ancient China and had a great influence on the politics, culture, art and thought of later generations. The feudal system and the Well-field system were two other institutions that developed at that time. According to legend it was founded by the Duke of Zhou and King Wu of Zhou.

The Ritual Music System is divided into two parts: ritual and music. The part of ritual mainly divides people's identity and social norms, and finally forms a hierarchy. The music part is mainly based on the hierarchical system of etiquette, using music to alleviate social conflicts.

Lu (Chinese: 魯; c. 1042 – 249 BC) was a vassal state during the Zhou dynasty of ancient China located around modern southwest Shandong. Founded in the 11th century BC, its rulers were from a cadet branch of the House of Ji (姬) that ruled the Zhou dynasty. The first duke was Boqin, a son of the Duke of Zhou, who was brother of King Wu of Zhou and regent to King Cheng of Zhou.

Lu was the home state of Confucius as well as Mozi, and, as such, has an outsized cultural influence among the states of the Eastern Zhou and in history. The Annals of Spring and Autumn, for instance, was written with the Lu rulers' years as their basis. Another great work of Chinese history, the Zuo Zhuan or Commentary of Zuo, was traditionally considered to have been written in Lu by Zuo Qiuming.

The Battle of Muye, Mu, or Muh (c. 1046 BC) was fought between forces of the ancient Chinese Shang dynasty led by King Zhou of Shang and the rebel state of Zhou led by King Wu. The Zhou defeated the Shang at Muye and captured the Shang capital Yin, marking the end of the Shang and the establishment of the Zhou dynasty—an event that features prominently in Chinese historiography as an example of the Mandate of Heaven theory that functioned to justify dynastic conquest throughout Chinese history.

Dan, Duke Wen of Zhou, commonly known as the Duke of Zhou, was a member of the royal family of the early Zhou dynasty who played a major role in consolidating the kingdom established by his elder brother King Wu. He was renowned for acting as a capable and loyal regent for his young nephew King Cheng, and for successfully suppressing the Rebellion of the Three Guards and establishing firm rule of the Zhou dynasty over eastern China. He is also a Chinese culture hero, with the authorship of the I Ching and the Classic of Poetry having traditionally been attributed to him, as well as the establishment of the Rites of Zhou.

King Cheng of Zhou (Chinese: 周成王; pinyin: Zhōu Chéng Wáng; Wade–Giles: Chou Ch‘êng Wang; 1055–1021 BC), personal name Ji Song, was the second king of the Chinese Zhou dynasty. The dates of his reign are 1042–1021 BCE or 1042/35–1006 BCE. Ji Dan, Duke of Zhou served as regent during his minority. His parents were King Wu of Zhou and Queen Yi Jiang.

The State of Cao (simplified Chinese: 曹国; traditional Chinese: 曹國; pinyin: Cáoguó) was a vassal state in China during the Zhou dynasty (1046–221 BC). The state was founded sometime in the 11th century BC by Shu Zhenduo of Cao (zh) (d. 1053 BC), a son of King Wen of Zhou and younger brother of King Wu of Zhou. With its capital at Taoqiu (陶丘), the State of Cao covered roughly the area of modern-day Dingtao County, Shandong Province. It was located on the flat country of the North China Plain about 50 miles east of the point where the current course of the Yellow River changes from east to north-east. To the northwest was Wey, to the northeast Lu and to the southeast Song.
