King Wu of Zhou (died c. 1043 BC), personal name Ji Fa, was the founding king of the

Zhou dynasty of China. He is considered one of the inaugurators of the Chinese dynastic cycle and a model ruler in the Confucian tradition.

King Wu's rule of the Predynastic Zhou began around 1050 BC, when he succeeded his father King Wen. Working with Jiang Ziya, he set out to complete his father's unfinished task of overthrowing the tyrannical Di Xin and his Shang dynasty. In 1046 BC, leading a coalition that included eight other states, King Wu routed Di Xin's army at the Battle of Muye and captured the Shang capital Yin, marking the end of the Shang and the rise of the Zhou.

As King of China, King Wu consolidated his rule by granting territory to his relatives and allies. He is regarded as a virtuous ruler by later Confucians, and his overthrow of the Shang features prominently in Chinese historiography as an example of the Mandate of Heaven.

Name

In bronze inscriptions, such as the Li gui, King Wu's name is occasionally contracted to wǔ 珷. It is generally considered to be a ligature, though it is subject to scholarly debate, with some arguing that it could be seen as a specialised variant of wu 武. The Yinggong ding (应公鼎) records his name as "Wǔ Dì Rì Dīng" (珷帝日丁) "King Wu, the Thearch of the Ding Day."

The Li gui inscription goes as follows:

珷征商隹甲子朝

King Wu's campaign against Shang, on the morning of the jiazi day.

King Wu's personal name was Ji Fa 姬發.

Lineage

King Wu was the second son of the Predynastic Zhou elder Ji Chang (posthumously titled King Wen of Zhou) and Tai Si. His older brother was Bo Yikao, who was passed over as a result of tradition. This is reflected in the Book of Rites. King Wu's grandfather Jili had likewise inherited Zhou despite having two older brothers.

In later accounts of Bo Yikao being passed over, it is said that Di Xin had killed him by lingchi. Among the earliest accounts of this lie in Records of Emperors and Kings (帝王世紀) of the 9th Century, which was then transmitted and quoted through later texts, such as the historical fiction Fengshen Yanyi. Given this only appears in accounts several centuries ahead of Di Xin's time, the historicity of this account is vanishingly unlikely.

Reign

The chronology of King Wu's overall reign is disputed. However, his reign as the ruler of Predynastic Zhou is thought to have begun in 1050 BC, and his reign as King of China is thought to have begun around 1046 BC. He is then thought to have died around three years later.

King of Predynastic Zhou

Upon his succession as king of Predynastic Zhou, King Wu worked with his father-in-law Jiang Ziya to accomplish an unfinished task: overthrowing the Shang dynasty and its ruler, Di Xin, who was alleged to be a cruel and inept tyrant. He resided largely in the capital, Fengjing, and the royal center remained in Zhouyuan (周原), Mount Qi. During the ninth year of his reign, King Wu made a sacrifice at Bi (畢). He was assisted by Duke Dan of Zhou, the Duke of Bi, and the Duke of Shao in carrying out King Wen of Zhou's ambition. He marched down the Yellow River to the Mengjin ford and met with more than 800 elders. He constructed an ancestral tablet with his father's posthumous name and placed it on a chariot in the middle of the host; considering the timing unpropitious, though, he did not yet attack Shang, stating "You still do not know the Mandate of Heaven, it is not yet possible."
