Liu Ju
Emperor Wu's first wife, Empress Chen Jiao, was deposed in 130 BCE after allegations that she attempted witchcraft to help her produce a male heir. In 91 BCE, similar allegations were made against Emperor Wu's Crown Prince Liu Ju, the son of his second wife Empress Wei Zifu. Liu Ju, in fear of Emperor Wu's believing the false allegations, began a rebellion in Chang'an which lasted for five days, while Emperor Wu was away at his quiet summer retreat of Ganquan (甘泉; in modern Shaanxi). After Liu Ju's defeat, he and his mother committed suicide.
