Empress Dowager Hu
Empress Dowager Hu forced Emperor Xuanwu's brother Yuan Yi the Prince of Qinghe, who was popular among the people and the officials for his humility and abilities, to have an affair with her, and Yuan Yi, by 520, was effectively the leader of the administration. He often curbed the abuses of power that both Yuan Cha and the eunuch Liu Teng (劉騰), who became powerful because he had once saved Empress Dowager Hu's life. Yuan Cha therefore had one of his associates, Song Wei (宋維), falsely accuse Yuan Yi of treason, and Empress Dowager Hu, for some time, put Yuan Yi under house arrest while she investigated, but eventually Yuan Yi was cleared. Yuan Cha, fearful of retaliation by Yuan Yi, conspired with Liu Teng, and after convincing the 10-year-old Emperor Xiaoming that Yuan Yi was in fact plotting treason, took Emperor Xiaoming into their custody and then carried out a coup against Yuan Yi and Empress Dowager Hu, executing Yuan Yi and putting Empress Dowager Hu under house arrest. Yuan Cha made Emperor Xiaoming's granduncle Yuan Yong the Prince of Gaoyang the titular head of government, but in effect, Yuan Cha, in association with Liu, was the actual regent.
