Biography
editHis mother, Lady Hyegyŏng of the Pungsan Hong clan was the great-great-great-granddaughter of Princess Jeongmyeong, the only daughter of Queen Inmok and King Seonjo. Due to intermarriage within the royal family, Princess Jeongmyeong was also his 5th great-grandaunt and 4th great-grandmother.
His maternal grandfather was Chief State Councilor Hong Bong-han, whose younger brother was Hong In-han, another prominent official of the period.
Yi Jeong was the first grandson of the King Yeongjo and his father, Crown Prince Sado, was Yeongjo's second and only surviving son (his elder brother, Crown Prince Hyojang, had died at the age of 9, seven years prior to Sado's birth). Sado suffered from severe mental disorders and was often at odds with his father.
Yi Jeong was born in 1750, in Changgyeonggung. Half a year later, King Yeongjo declared him grand heir (왕세손; 王世孫).
In December 1751, his aunt-in-law, Crown Princess Hyeon, died. Soon after, on 17 April 1752, Yi Jeong also passsed away. Yeongjo took both of their deaths hard and grieved for some time.
He was given a state funeral,[1] on special instructions from his grandfather. Yeongjo gave him the posthumous name Uiso (의소; 懿昭), and personally composed the eulogy and epitaph. His body was buried to the south of Mount Ahnhyon,[2] and the tomb was known as Uisomyo (의소묘; 懿昭墓).
His younger brother, Yi San, was born several months after his death; he became gand heir in 1759, and would ascend to the throne in 1776. In 1762, Crown Prince Sado was executed through starvation after being locked in a rice chest.
During Gojong's reign, his tomb was upgraded to Uiryeongwon (의령원; 懿寧園).[3] On 7 June 1949, it was relocated to the Seosamneung Cluster in Goyang, Gyeonggi Province.
