Queen Mundeok

Queen Mundeok of the Chungju Yu clan was a Goryeo princess as the youngest daughter and child of King Gwangjong and Queen Daemok, also the youngest sister of King Gyeongjong.

Biography
It is unknown what year the future queen was born, but she was the youngest child of King Gwangjong and Queen Daemok. Although she was recognized as being part of the royal Wang clan, she was put under her paternal grandmother’s clan, the Chungju Yu clan.

She firstly married Wang Gyu, who was also the grandson of Lady Heondok and King Taejo, the only son of Crown Prince Sumyeong. They had a daughter together who would eventually marry King Mukjong, the son of King Gyeongjong.

But after Wang Gyu’s death, Lady Yu remarried again and became a queen consort through her marriage with her half first cousin, King Seongjong as his first and primary wife. From this marriage, Queen Mundeok became the fifth reigned Goryeo queen who followed her maternal clan after Queen Heonjeong, her half first cousin and the first Goryeo queen who remarried.

Although her death date was unknown, but seeing that her son-in-law (formerly nephew), King Mokjong gave her posthumous names in 997, it seems that she died before that.
