霊太后
Yuan Cha (元叉) (died 525), courtesy name Bojun (伯雋), nickname Yecha (夜叉), was an official of the Chinese/Xianbei dynasty Northern Wei, who initially came to power as the brother-in-law of Emperor Xiaoming's mother and regent Empress Dowager Hu. In 520, after a conflict with her lover Yuan Yi (元懌) the Prince of Qinghe, he killed Yuan Yi and put Empress Dowager Hu under house arrest, effectively taking over as regent. In 525, a countercoup by Empress Dowager Hu restored her, and bowing to public pressure, she forced him to commit suicide.
