Sima Yu
In 299, the political firestorm became too big for Zhang Hua to handle after Empress Jia Nanfeng framed Sima Yu for treason in 299 and had him deposed. In the following year, fearing that Sima Yu would make a comeback, Empress Jia had him murdered. Sima Lun (the Prince of Zhao), a granduncle of Emperor Hui, plotted a "coup d'état" to remove Empress Jia from power. He tried to persuade Zhang Hua to join him, but Zhang Hua was reluctant to do so. Later that year, after Sima Lun successfully overthrew Empress Jia, he had her several of her supporters and associates (including Zhang Hua) executed along with their families.
