Queen Jeongseong (정성왕후 서씨; 12 January 1693 – 3 April 1757[1]), of the Daegu Seo clan, was the first wife of King Yeongjo of Joseon and the adoptive mother of Crown Prince Sado.[2]


The future queen was born on 12 January 1693 in Gahoebang (가회방, 嘉會坊). She was the second daughter and fourth child of Seo Jong-jae and Lady Yi of the Ubong Yi clan.

In November 1703, at the age of ten, she married the eight-year-old Prince Yeoning. As the wife of a prince, she was given the title of Princess Consort Dalseong (달성군부인). On their first night of marriage, it was said that Prince Yeoning had asked how were the hands of the princess so pretty. The princess responded by saying that she never did any labor to get them dirty. This comment had unsettled the Prince because it reminded him of his mother, Royal Noble Consort Suk.

It was said that from then on to her death as Queen, the Princess was not visited much from the Prince.

In 1720, her husband was appointed as Crown Prince (왕세제, 王世弟), As his wife, Dalseong was given the title Crown Princess Consort (왕세제빈).

In 1724, Prince Yeoning's older brother, King Gyeongjong died. Prince Yeoning ascended the throne on 30 August of that year as King Yeongjo and she became his queen consort.

As queen, it was said that she held a generous character to her. The Queen had also cherished and treated Crown Prince Hyojang, Yi Jeong-bin's son, and Crown Prince Sado, Yi Yeong-bin’s son, as if they were her own sons.

The Queen died at Changdeok Palace on 3 April 1757. Her death distressed Crown Prince Sado, contributing to his declining mental condition.[3] Queen Jeongseong had no biological children.
