Yun Po-sun
2nd President of South Korea (1897-1990)
Yun Po-sun (Korean: 윤보선, pronounced [junbosʌn] or [jun] [posʌn]; August 26, 1897 – July 18, 1990) was a South Korean politician and activist who served as the second president of South Korea from 1960 to 1962. He was the only president of the short-lived Second Republic of Korea, and served as little more than a figurehead due to its nature as a parliamentary system.
Having entered politics after World War II, Yun served as Secretary to Korea's Chief of Staff in 1947, and was Mayor of Seoul in 1948. He served as Commerce Minister for the newly liberated Korea from 1949 to 1950. In 1955, Yun helped establish the South Korean Democratic Party. He was forced to resign the presidency by Park Chung Hee as a result of the May 16 coup in 1961.
Early life
Yun Po-sun was born in Dunpo-myeon, Asan, South Chungcheong Province in 1897. He was a son of Yun Chi-so (윤치소, 尹致昭, 1871–1944) and Lady Yi Beom-suk (이범숙, 李範淑, 1876–1969). Yun Chiso is the second son of Yun Yeong-ryeol (윤영렬;尹英烈). Yun Yeong-ryeol is an 8th generation descendant of the prominent Joseon scholar-official Yun Tusu.

Why this record matters
“Yun Po-sun” is worth following because a concise public description often conceals a longer documentary argument. Here, Po-sun, President and South provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q192049. VIAF identifies the subject as 265768302. The Library of Congress control number is nr93006067. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1897, 1990, 1960 and 1962.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
