Queen Seonui

The future queen was born on 14 December 1705 during the reign of King Sukjong. Her father, Eo Yu-Gu, was a member of the Hamjong Eo clan, and her mother was a member of the Jeonju Yi clan.

Her 4th cousin eventually married Lady Hyegyeong’s father's cousin, Hong Sang-han. They would eventually become the great-grandparents of Hong Hyeon-ju; the husband of Princess Sukseon, a daughter of King Jeongjo and Royal Noble Consort Su of the Bannam Park clan.

In 1718, when Lady Eo was 14 years old, she married the 30 year old Crown Prince Hwiso and was appointed as crown princess consort. When her husband ascended to the throne and became the 20th Joseon monarch (temple name: Gyeongjong) in 1720, she automatically became queen consort.

The King suffered ill health and was unable to produce an heir—or to do much of anything for that matter. During his reign, the Noron and Soron factions battled for power. The Soron faction were the ruling political faction and supported Gyeongjong, and the Noron faction supported his half-brother, Prince Yeoning. The Noron faction and his step-mother, Queen Dowager Hyesun pressured him to appoint Prince Yeoning as his heir.

According to one theory, the Queen opposed Prince Yeoning and planned to secretly adopt Prince Milpung (밀풍군, Milpung-Gun), the great-grandson of Crown Prince Sohyeon, King Injo's first son. However, two months after the King's enthronement, Prince Yeoning was installed as Crown Prince (Wangseje, 왕세제, 王世弟).

Gyeongjong later died in 1724 and the Queen was honoured as Queen Dowager Gyeongsun. Prince Yeoning succeeded his brother as the 21st Joseon monarch (temple name: Yeongjo). After she knowing that her family were suspected of an assassination attempt on Yeongjo, Gyeongsun was enraged and rejected all the food. She died of starvation in 1730 in Jeoseung Hall of Gyeonghui Palace.

She was posthumously given the title of Queen Seonui (선의왕후; 宣懿王后).

After her death, Jeoseung Hall was accommodated and converted into living quarters for Crown Prince Sado to which the name was changed to Chwiseondang (취선당), and was also a Soju room. In her memoir, Lady Hyegyeong stated that the reason why Crown Prince Sado's mental state worsened or started was because of the ominous environment that the hall living quarters had; Royal Noble Consort Hui, Gyeongjong's mother, was executed in the hall in 1701, and Queen Seonui died 29 years later in the same hall.
