Queen Uijeong

Queen Uijeong of the Gim clan (Hangul: 의정왕후 김씨, Hanja: 義靜王后 金氏) or Queen Gyeongsun (Korean: 경순왕후; Hanja: 景順王后) and formally called as Queen Mother Gwangjeong (Korean: 광정태후; Hanja: 光靖太后) was a Goryeo Royal Family member as the 3rd daughter Duke Gangneung, grandson of King Munjong who became the Queen Consort though her marriage with her half second cousin once removed, King Myeongjong of Goryeo as his first and primary wife. She also became the mother of his successor, Gangjong of Goryeo[1] and two another daughters.[2] She was the sister of Queen Janggyeong, Marchioness Gaeryeong and Queen Seonjeong, also the one of several Goryeo queens to take their mother's clan name over their father's.[3]

From all of her families' records, just she who didn't appear clearly about her life. It was believed that she married Myeongjong when he was still "Marquess Ikyang" (익양후) and "Duke Ikyang" (익양공), but later died after his ascension to the throne succeeded King Uijong. When their son ascended the throne in 1211, he then honoured his mother as the Queen Mother (태후, 太后) and gave her Posthumous name.[4][5] Although she never became Queen consort, but as an example of a queen, it seems that her ritual was again performed and after her husband death, Choe Chung-heon performed it.
