## Biography
### Early life

The future Grand Internal Princess Consort Hadong was born into the Hadong Jeong clan on 23 September 1522 as the daughter of Jeong Se-Ho, and his wife, Lady Yi of the Gwangju Yi clan.
Her father, Jeong Se-Ho was the son of Jeong Sang-Jo and Lady Ahn of the Juksan Ahn clan; making him the grandson and Lady Jeong a great-granddaughter of Chŏng Inji. Her paternal grandmother, Lady Ahn, was the granddaughter of Princess Jeongui; who was the second daughter of Queen Soheon and King Sejong. Thus making her the maternal great-great-granddaughter through her grandmother.
Meanwhile, her mother was the daughter of Yi Se-geol and Lady Jeon of the Jeongseon Jeon clan. Lady Jeong had 2 older brothers and a younger brother. Her paternal cousin, Lady Jeong of the Hadong Jeong clan, eventually became the grandmother of Queen Yu, the wife of King Gwanghaegun.

### Marriage and later life

She later married Yi Cho when he was still Prince Deokheung (덕흥군; 德興君) and was honoured as Princess Consort Hadong (하동군부인; 河東郡夫人). Her father was then honored as Duke Hyogan, Internal Prince Hadong (효간공 하동부원군).
During her marriage, she gave birth to a son in 1545, a second son in 1546, a daughter in 1548, and a third son in 1552.
On 24 June 1567, during King Myeongjong's 22nd year of reign, she died at 46 years old. Her tomb is located near from her husband's tomb.

### Seonjo's ascension to the throne

Two months after her death, her third son, Yi Yeon, Prince Haseong succeeded Myeongjong who died without a royal heir. Thus becoming Myeongjong's adopted son when the prince ascended the throne as the 14th king of Joseon. Her husband couldn't be King (왕; 王) because of his low background, so the throne was immediately passed down to his legitimate son. On 1 November 1569, as the Princess Consort was the biological parent of the reigning King, she was granted the royal title of Princess Consort Hadong (하동부부인; 河東府夫人) at first, but was later changed to Grand Internal Princess Consort Hadong (하동부대부인; 河東府大夫人).
