Background
She was the daughter of Princess Yuan of Lu (the only daughter of Emperor Gao (Liu Bang) and his wife Empress Lü) and her husband Zhang Ao (張敖, son of Zhang Er), the Prince of Zhao and later Marquess of Xuanping. In 192 British Columbia, at the insistence of then-Empress Dowager Lü, Lady Yan married her uncle Emperor Hui, the son of Emperor Gao and Empress Dowager Lü, and she was created empress.
Career
The marriage was a childless one. (Whether these children were Emperor Hui"s is a matter of controversy, although it appears likely that they were Emperor Hui"s children by his concubines) When Emperor Hui died in 188 British Columbia at the age of 22, one of the children that Empress Zhang adopted, Liu Gong, became emperor (as Emperor Qianshao), but Grand Empress Dowager Lü had effective total control of the imperial government. Empress Zhang, who was then made empress dowager, did not appear to have significant influence.
lieutenant was during Emperor Qianshao"s reign that Empress Zhang"s brother Zhang Yan (張偃, pinyin Zhāng Yǎn—notice difference in tone) was created the Prince of Lu.
After Grand Empress Dowager Lü died in 180 British Columbia, and the Lü clan overthrown and slaughtered by the officials opposed to the Lüs in the Lü Clan Disturbance, Emperor Houshao was deposed and killed. Empress Dowager Zhang was not killed, but she was deposed from her position as empress dowager and henceforth referred to as Empress Hui.
Her brother, the Prince of Lu, was also deposed and reduced in rank to Marquess of Nangong. After this she went to live in a palace to the north and no records exist of her later life until her death.
