Xiao Zhangmao

Xiao Zhangmao (蕭長懋) (458 – 25 February 493), courtesy name Yunqiao (雲喬), nickname Baize (白澤), formally Crown Prince Wenhui (文惠太子, literally "the civil and benevolent crown prince"), later further posthumously honored as Emperor Wen (文皇帝) with the temple name of Shizong (世宗), was a crown prince of the Chinese Southern Qi dynasty. He was Emperor Wu (Xiao Ze)'s oldest son but predeceased his father. After his death, his son Xiao Zhaoye became crown prince and eventually succeeded Emperor Wu but was soon thereafter overthrown by Emperor Wu's cousin Xiao Luan, who usurped the throne. By 498, all of Xiao Zhangmao's descendants had been exterminated.
