Yi Suhyeong (; 1435–1528) was a Korean politician and Confucian scholar, writer, and poet of the Joseon period. His art names were Dochon and Gongbukheon. It was after King Sejo of Joseon took possession of the throne by force and after the loss of his nephew, that he left politics and secluded himself away from society.
He studied at Kim Dam's school and later married one of Kim's daughters. In 1450, he was a successor of an ancestral government position at a young age of 17. His political post was then succeeded by Sung Yorang, Junsaeng Seoryung and Bu Sajik .
In 1455, Sejo of Joseon usurped the throne held by his nephew, Danjong of Joseon. Yi Suhyeong responded in resentment, and left the government service. He retired to a hermitage in the mountains.[1]
After the assassination of his nephew, Danjong in 1457, he mourned for him in 3 years. Missing his nephew, as he had since Danjong's death, he had cut himself completely from all human contact,[2] for the next 70 years.
