Zhang Ao
Traditional Chinese
Simplified Chinese


Born in the Kingdom of Zhao, he was the son of Zhang Er (張耳), a Zhao general and participated in his father's campaigns against the last armies of the Qin. The hegemon king Xiang Yu of Western Chu made Zhang Er king of Changshan (常山王) during the Eighteen Kingdoms Period, but Zhang Er changed his loyalty to Liu Bang, the eventual founder of the Han dynasty and was titled as King of Zhao. In 202 BC, Zhang Er died and Zhang Ao succeeded him to the throne of Zhao. He married Liu Bang's daughter, Princess Yuan of Lu (posthumous title). In 198 BC, his plot to kill Liu Bang was revealed, but he was pardoned and only demoted to Marquis of Xuanping (宣平侯). He was succeeded as king of Zhao by the emperor's young son Liu Ruyi. Zhang Ao died during the reign of the Empress Dowager Lü (r. 188–180 BC).


His posthumous title was Marquis Wu (武侯), but he was also venerated as King Yuan of Lu (魯元王). Zhang Ao's daughter Zhang Yan became the wife of Emperor Hui (r. 195–188 BC), her uncle.
