Hyogong

Queen Hyogong of the Pyeongchang Yi clan (; 1207–?) was the wife Yi Ansa and mother of Yi Haengni, making her great-grandmother to Yi Jachun who was the father of Yi Seonggye, Joseon's founder. Among the Joseon queens, she was the only one who came from the Yi clan and honoured as Hyo-Bi at first.

Biography Her 4th great-grandfather was Yi Gwang, Prince Baekoh (; 1126–1170) from Pyeongchang-gun, Gangwon Province. Because King Sejong disallowed a man and woman from the same clan to marry and any woman with the surname Yi, she became the only Joseon Queen Consort whom came from a Yi clan in Joseon history.

In 28 July 1392, when Taejo established a new dynasty, she was granted the royal title Consort Hyo along with her husband whom was granted the title King Mok . Later on 22 April 1411, King Taejong, gave her a posthumous name Queen Hyogong . Her tomb was located in Alleung, Neung-ri, Gapyeong-myeon, Siheung-gun, Hamgyeongnam-do along with her husband.
