Empress Guo (明元郭皇后, Minh Nguyên Quách hoàng hậu; d. 264), native of Xiping, was the empress of Emperor Ming of Wei (Cao Rui) and Empress Dowager during the reigns of Cao Fang, Cao Mao, and Cao Huan during the Three Kingdoms era.
Elevated to Empress on Cao Rui’s deathbed in 239, Empress Dowager Guo occupied a position of immense constitutional authority for twenty-five years as the living embodiment of imperial legitimacy in Cao Wei. In 249 during the Gaoping Tombs coup, Sima Yi presented his memorial to Empress Dowager Guo to legitimize the purge of regent Cao Shuang. In 254, when Sima Shi deposed Cao Fang, Empress Dowager Guo tenaciously defended royal rights, refusing to yield the Imperial Jade Seal until Sima Shi guaranteed Cao Mao’s succession. In 260, when Cao Mao was brutally assassinated by Sima Zhao’s henchman Cheng Ji, Empress Dowager Guo was forced in tears to sign the deposition decree, passing away in 264 shortly before the formal usurpation of the Jin Dynasty.
Role in History (Sanguozhi)
Records of the Three Kingdoms (Sanguozhi, vol. 5, Biographies of Consorts): “Empress Mingyuan was discerning and courageous. When Sima Shi demanded the Imperial Seal, the Empress Dowager held it fast, declaring: ‘The seal belongs to the ancestors of Cao; on what authority do you claim it?!’ Her words shook the palace halls.”
