Prince Sanggye

Prince Sanggye or Prince Wanpung (21 January 1769 – 20 November 1786) was a Korean prince, an adopted son of Jeongjo of Joseon and biological child of Prince Euneon.

Biography Prince Sanggye was born as Yi Jun, on 21 January 1769, in Hanseong. He was the son of Prince Euneon and his wife, Princess Consort Sangsan of the Jincheon Song clan, a daughter of Song Rak-hyu. His father was the son of Crown Prince Sado and his great-grandfather was King Yeongjo. During his early childhood, he was adopted by Hong Guk-yeong, the fourth cousin-once-removed of Lady Hyegyŏng, as the son of his sister, Wonbin Hong, and King Jeongjo.

At the time, Ku Seon-bok and other Joseon noblemen supported Yi Jun as heir to the throne, but as King Jeongjo was in his mid-20s and could still be expected to produce a child, Kim Jong-su, along with many of Jeongjo's ministers, who were enemies of Hong Guk-yeong, demanded his and Prince Wanpung's removal.

On 7 May 1779, Wonbin Hong suddenly died and the king's ministers repeatedly accused Hong Guk-yeong and the prince.

On 26 September 1779, Hong Guk-yeong was expelled from power and jailed. Prince Wanpung's title was demoted to Sanggye and his name was also changed from Yi Jun to Yi Dam, but the king's retainers continued their attacks.

On 21 January 1784, he was married to a lady from the Pyongsan Shin clan, daughter of Shin Oh.

On 20 November 1786, Prince Sanggye suddenly died, suspected to have been poisoned. Some accused Hong Guk-yeong or his biological father, Prince Euneon, and others accused some of King Jeongjo's retainers. After his death, he was buried at Yeonhul Castle, near modern Sinchon Station and Yonsei University. His funeral was personally arranged by King Jeongjo.

Prince Sanggye was not reinstated for many years. In 1801, his mother, Princess Consort Sangsan, and his wife, Princess Consort Shin, were executed for their conversion to Catholicism (Neo-Confucianism was the state religion of Joseon).

He was eventually amnestied and rehabilitated on 17 June 1849, by King Cheoljong, who was his half-nephew.
