Emperor Fei
In 369, after Huan Wen launched a major attack against Former Yan but suffered a devastating defeat at the hands of Murong Chui, he considered another way to showcase his power. He decided to depose Emperor Fei, and he spread false rumors that Emperor Fei was impotent and that his sons were actually sons of men that he favored (implying a homosexual relationship between him and those men). In winter 371, Huan forced Empress Dowager Chu to issue an edict deposing Emperor Fei and replacing him with Sima Yu, who took the throne with trepidation but felt he had no choice.
