Queen Seonui (Goryeo)

Queen Seonui of the Chŏngju Yu clan or formally called Grand Queen Mother Seonui, was a Goryeo princess, second daughter of King Taejo and Queen Jeongdeok. She married her half brother, Daejong of Goryeo, giving birth to three sons (among which King Seongjong), and two daughters, Queen Heonae and Queen Heonjeong.

Seonui and her husband died when their children were still young, so they were raised by their paternal grandmother. Both she and her husband were posthumously honoured as a king and queen after their second son, Wang Chi, ascended the throne.
