Heonjeong

Queen Heonjeong of the Hwangju Hwangbo clan (; 966–993), or formally called as Grand Queen Mother Hyosuk during her son's reign, was a Goryeo royal family member as the third daughter of Wang Uk and youngest sister of King Seongjong. She later became the fourth wife of her first cousin, King Gyeongjong. After his death, she had an affair with her half uncle, giving birth to King Hyeonjong.

Not much is known about her early life beside that she and her siblings were raised by their paternal grandmother.

Affair with Wang Uk When her husband King Gyeongjong died at the young age of 26, Heonjeong was in her mid-teens. As a widow she moved to her maternal home outside of the palace in Gaegyeong; the house was close to her half uncle Wang Uk's, located in Wangnyun Temple , Songak Mountain. Since the law forbade the dowager queen from approaching other men, she often visited her uncle and, as they spent time together, they became close.

One night in 991, after praying for her late husband's happiness in Wangnyun Temple, Wang Uk and the Queen confirmed each other's feelings and embraced their love. As a result, Heonjeong became pregnant.

As the people around them kept quiet, the court was unaware of their affair. Knowing what she'd done and feeling the fetus growing in her belly, the Queen was anxious and wanted to die because she was supposed to remain faithful to her late husband and not have an affair with another man, even becoming pregnant by her own uncle. She held on to a willow branch and ultimately gave birth to a son, Wang Sun, but she died soon after.
