司馬倫
In 300, under the advice of a prince she favored -- Sima Lun the Prince of Zhao, Emperor Wu's uncle—Empress Jia decided to eliminate Crown Prince Yu as a threat. She sent assassins and had Crown Prince Yu assassinated. He was buried with honors due a prince—under the title of Prince of Guanling. Sima Lun's intent was, however, to use this assassination as excuse to overthrow Empress Jia, and he did so later that year. He had Crown Prince Yu reburied with the honors due a crown prince and had him given the posthumous name Minhuai. He also welcomed Crown Princess Wang back to the palace, along with Crown Prince Yu's surviving sons Sima Zang () (whom he had created crown prince) and Sima Shang (). However, when Sima Lun then usurped the throne briefly in 301, Crown Prince Zang was killed. After Emperor Hui's restoration later that year, Sima Shang was created crown prince, but died in 302, extinguishing Crown Prince Yu's line.
