Known by many names, Jiang Ziya was a Chinese noble and sage who played a criitical role in the overthrow of the Shang Dynasty and the establishment of the Zhou Dynasty afterwards. The last ruler of the Shang Dynasty, King Zhou of Shang, was a tyrannical and depraved man corrupted by his possessed concubine Su Daji. After having dutifully served in the Shang court for twenty years, he found King Zhou's reign insufferable, and feigned madness to be excused from court life.

He was eventually found and recruited by King Wen of Zhou, reportedly at the age of seventy-two, after Jiang Ziya agreed to serve him. Given the title of Jiang Taigong Wang ('The Great Duke's Hope') and appointed as prime minister, he served King Wen's son, King Wu, after the former died. Once the people of Shang Dynasty had had enough of King Zhou's tyrannical rule and rose up against him, Jiang Ziya led an army to overthrow him, defeating the Shang army at the Battle of Muye in 1043 BCE. The Shang Dynasty fell, and the Zhou Dynasty rose in its place to rule over all of China.

He is also a prominent character in the Ming Dynasty classic novel 'Fengshen Yanyi', where he has mystical powers and is considered the archrival of Su Daji. After King Zhou's death, Su Daji was captured as she attempted to flee and executed on the order of Jiang Ziya himself. He is considered by some as the most famous Prime Minister in Chinese history, and one of the world's greatest strategists.
