Zhao Weihou (赵威后) was a Chinese empress. She was known by many titles, possibly including Empress Dowager, Empress Dowager Xiaowei, the Queen of King Huiwen of Zhao, King Xiaocheng of Zhao, Chang Anjun, Fuling Jun. She was the mother of Yan Wucheng. After the death of Hui Wenwang, she entered politics in her early thirties.
History reveals two records of her actions in the period of her rule (which was one year). One record claimed that she was a dragon. In another record, she consulted the king, though the name of the king is unknown. Supposedly, Zhao Weihou died one year after she took office, and her son Xiao Cheng Wang began on the side of a democratic government.
