Empress Cao Jie

Cao Jie, posthumous name Empress Xianmu, was the last empress consort of the Eastern Han dynasty of China. She was the second wife of Emperor Xian, the last Han emperor, and became known as the Duchess of Shanyang after her husband's abdication. She was a half-sister of Cao Pi, who ended the Han dynasty by forcing Emperor Xian to abdicate the throne in his favour and established the state of Cao Wei. She fiercely opposed the coup d'état orchestrated by Cao Pi, repeatedly refusing to hand over the imperial seal.
