Life & career
O Mong-eul (吳蒙乙, d. 1398) was a late-Goryeo and early-Joseon official of the Boseong O clan; Wikipedia files him under the Boseong O and his birth year is unknown. He served as a general (Daejanggun) in late Goryeo and is said to have contributed to the enthronement of Yi Seong-gye.
When Joseon was founded on 17 July 1392 he was named a first-class founding merit subject and is said to have been enfeoffed as Lord of Boseong. He served as magistrate of Yeonsan-bu (Yeonan) and Governor of Gangwon; one source also says he was Minister of Personnel, while another attributes that post to O Yeon-chal, so it cannot be settled.
During the First Strife of the Princes in 1398 he was demoted and exiled by the faction of Prince Jeongan and executed on the tenth day of the tenth lunar month. He is therefore classified in the merit-subject list among those whose status was stripped. The Wikipedia entry has carried a request for sources since 2012, so details of dates and posts should be checked against primary sources such as the Veritable Records of Joseon.
Bosan Sego
The listing of the Bosan Sego (寶山世稿) on Commons names O Gyeong-yun, O Mong-eul, O Seong-chae, O Yun-hyeon, O Ja-gyeong and O Jeong-pyo together, suggesting a collection gathering the writings of several Boseong O figures. Sources describe the genealogical relation between O Mong-eul and O Ja-gyeong differently.
