曹皇后
Empress Cao (曹皇后, personal name unknown) (died January 11, 937), formally Empress Hewuxian (和武憲皇后), was an empress of the Chinese Five Dynasties and Ten Kingdoms Period state Later Tang. Her husband was Later Tang's second emperor Li Siyuan (Emperor Mingzong), and she was empress dowager during the subsequent reigns of his son Li Conghou (Emperor Min) and adoptive son Li Congke. Eventually, when her son-in-law Shi Jingtang rebelled against Li Congke, establishing his own Later Jin and attacked the Later Tang capital Luoyang, she died in a mass suicide with Li Congke, his family, and some officers.
