Empress Jia Nanfeng

Jia Nanfeng, nicknamed Shi (峕), was a Chinese empress consort. She was a daughter of Jia Chong and the first wife of Emperor Hui of the Jin dynasty and also a granddaughter of Jia Kui. She is commonly seen as a villainous figure in Chinese history, as the person who provoked the War of the Eight Princes, leading to the Wu Hu rebellions and the Jin Dynasty's loss of northern and central China. Between July 291 to May 300, she ruled the Jin empire from behind the scenes by dominating her developmentally disabled husband.
