Chu Suiliang

Chu Suiliang (褚遂良) (597–658), courtesy name Dengshan (登善), formally Duke of Henan (河南公), was a chancellor of the Chinese dynasty Tang Dynasty, during the reigns of Emperor Taizong and Emperor Taizong's son Emperor Gaozong. He became increasingly trusted by Emperor Taizong toward the end of his reign and was charged with the responsibilities of serving as the imperial historian and providing honest advice. At Emperor Taizong's death, Chu was entrusted with the responsibilities of assisting Emperor Gaozong, along with Emperor Gaozong's uncle Zhangsun Wuji. In 655, over his strenuous opposition to Emperor Gaozong's removal of his first wife Empress Wang and replacing her with Empress Wu (later known as Wu Zetian), Chu was demoted, and that began a series of demotions, eventually to be the prefect of the extremely distant Ai Prefecture (愛州, roughly modern Thanh Hoa Province, Vietnam). He died in exile in 658.
