Shangguan Wan'er
Shangguan Yi (; 608 – 4 January 665), courtesy name Youshao (), formally Duke of Chu (), was a Chinese poet and politician. He was an official of the Chinese dynasty Tang Dynasty, serving as chancellor during the reign of Emperor Gaozong. In 664, with Emperor Gaozong displeased with his wife Empress Wu (later known as Wu Zetian) for her controlling behavior, and also he grew resentful of her controlling influence in the empire, Shangguan proposed that Empress Wu be deposed, a proposal that Emperor Gaozong was initially receptive to but disavowed once Empress Wu discovered it. Empress Wu then had Shangguan accused of plotting treason with Emperor Gaozong's oldest son, the former crown prince Li Zhong (who had been displaced by Empress Wu's son Li Hong), and Shangguan was executed. After that, Empress Wu had more complete and direct control over the government and Emperor Gaozong himself, and exercised excessive dominion. also, His granddaughter Shangguan Wan'er later served as a key secretary to Empress Wu and a beloved concubine to her son Emperor Zhongzong.
