Cheonchu Dowager Queen

Queen Cheonchu (Cheonchu Taehu, 964–1029), formally titled Queen Heonae, was a consort of Gyeongjong, the fifth king of Goryeo, and the mother of Mokjong, its seventh king. When her elder brother Seongjong died and her young son Mokjong took the throne, she assumed the regency and effectively directed the politics of early Goryeo. She became widely known as "Cheonchu Taehu" after Cheonchujeon, the palace hall where she resided.
