司马颙
As Emperor Hui continued to be a pawn of the princes during the War of the Eight Princes, Empress Yang herself appeared to have had little influence. She was, however, frequently used as an excuse for certain conspirators' actions, and during the span from 304 to 306 she was deposed four times and restored four times, often in conjunction with her husband's nephew Sima Qin (司馬覃)'s fortunes as crown prince. She was nearly killed after her fourth removal in 305, as Sima Yong, then holding Emperor Hui at Chang'an and leaving her in the capital Luoyang, became convinced that she was easily usable by his opponents as a rubber stamp, and so he ordered that she be forced to commit suicide. The governor of the capital region, Liu Tun (劉暾) offered a petition to save her life, which nearly cost him his own—as Sima Yong ordered to have him arrested, and he was barely able to flee with his life. However, after Liu's intercession, for whatever reason, Sima Yong cancelled the order to have her forced to commit suicide.
