Yi Sung hun

Short Biography

Yi Seung-Hun (1756 - April 8, 1801, Ja: Jasul (子述), Ho: Mancheon, baptismal name Peter) was one of the first Roman Catholic martyrs in Korea. He was born in 1756 in Seoul. His father was Soam Yi Dong-uk (蘇巖 李東郁, 1739-?) who rose to the rank of champan (vice-minister) and, after possible initial interest, fiercely opposed the spread of Catholic teachings. His mother was a sister of Yi Ga-hwan (李家煥, 1742-1801), one of the Catholics executed with him in 1801. Yi Seung-hun first came into contact with Catholicism via Yi Byeok in 1779. In 1783-4, he accompanied his father on a diplomatic mission to Beijing, China, and on the suggestion of Yi Byeok contacted the Catholic priests there. He was baptised in Beijing in the spring of 1784. This was the first time that a member of the Korean yangban class was formally baptised as a Christian and he returned to Korea with books, crucifixes, and other Catholic artifacts. Yi Byeok then seems to have taken some time to study the books before declaring himself convinced. He then set about evangelizing those around him, including Gwon Cheol-sin and his younger brother Gwon Il-sin. This was also the moment when he spoke of the Catholic faith to the brothers Jeong Yak-jong, Jeong Yak-jeon, and Jeong Yak-Yong (who recorded the event in his epitaph myojimyeong.
