During the Zhouconquest of Shang, Jiang Ziya, a native of Ju County served as the chief minister to King Wu of Zhou, the same position he had held in service to King Wu's father. Following Zhou victory, the lands comprising much of the Shandong peninsula and some nearby surrounds were established as the state of Qi, with the Jiang clan charged with ruling and defending them. After King Wu's death, Ziya remained loyal to the Duke of Zhou's regency during the Three Guards' failed rebellion. Jiang Ziya was also called Lü Shang so the state of Qi is ruled by the Lü family of the Jiang clan and was commonly known as Jiang Qi.
