Liu Yizhi

Liu Yizhi (劉禕之; 631 – June 22, 687), courtesy name Ximei (希美), was a Chinese politician of the Tang dynasty, serving as chancellor during the first reign of Emperor Ruizong. He was initially a trusted advisor of Emperor Ruizong's powerful mother Empress Dowager Wu (later known as Wu Zetian), but later offended her by suggesting privately that she should return imperial powers to Emperor Ruizong, and in 687, she ordered him to commit suicide.
