Xin dynasty
Empress Wang (王皇后, personal name unknown) (8 BC – 23 AD), formally Empress Xiaoping (孝平皇后), formally during her father Wang Mang's Xin dynasty Duchess Dowager of Ding'an (定安太后) then Princess Huanghuang (黃皇室主), was an empress during the Han Dynasty and the last empress of the Western Han Dynasty. She was the daughter of the eventual usurper Wang Mang, who established the Xin Dynasty. Her husband was Emperor Ping. She is largely viewed by historians as a tragic figure, the victim of circumstances who tried to remain loyal to her husband of only a few years, but whose faithfulness to her husband's dynasty eventually led her to commit suicide at the end of her father's reign.
