Queen Gyeongseong

Queen Gyeongseong of the Gyeongju Gim clan (Hangul: 경성왕후 김씨, Hanja: 敬成王后 金氏; d. 23 September 1086[3][4]) was a Korean Royal Princess as the only daughter of Hyeonjong of Goryeo and Consort Wonsun. She also become the Korean Queen Consort as the first wife of Deokjong of Goryeo,[5][6] who was initially her half-brother.[7][8] As a Royal Princess, she therefore was called as "Oldest Daughter of the Gyeongheung Residence" (경흥원 장녀, 景興院 長女) since it was her mother's official residence.

Since the same clan couldn't married, she then followed her maternal clan (Gyeongju Gim[9])[10] and became the 19-years-old Deokjong's queen consort in 1034. However, their marriage lasted only 7 months which Deokjong died in the same year, so she lived 52 years alone until her death in 1086. During her lived-alone, at least she watched the reigns of four monarchs (Jeongjong, Munjong, Sunjong and Seonjong). She later buried in Jilleung (질릉, 質陵), the same tomb with her husband[11] and received her Posthumous name in 1096.
