Zhang Jian (Tang dynasty)
Zhang Jian, courtesy name Shiyue, was a relative of the Tang Dynasty emperors who became a duke.
He was a great-nephew of Emperor Gaozu of Tang, the founder of the dynasty. He did good service in aiding the Emperor to consolidate his power; and on one occasion rode alone into the camp of a revolted tribe of Turko-Scythians, and succeeded in gaining their submission. He held many important posts, and was ennobled as Duke. Posthumously named Mi.
