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 Yeongjo of Joseon. 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, Royal Noble Consort Won of the Pungsan Hong clan, 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 Crown Prince Wanpung's removal.
On 7 May 1779, Lady Hong Won-bin of Pungsan suddenly died and the King's ministers repeatedly accused Hong Guk-yeong and the Crown Prince.
On 26 September 1779, Hong Guk-yeong was expelled from power and jailed. Crown Prince Wanpung was dethroned and removed from the peerage. His title was changed from Wanpung 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 Lady Shin of Pyeongsan, a daughter of Shin Oh.
On 20 November 1786, Prince Sanggye suddenly died and it's 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 his adoptive father, Jeongjo of Joseon.
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 belief in Catholicism.
He was eventually amnestied and rehabilitated on 17 June 1849, by King Cheoljong, who was his half-nephew.
