Park Chung-hee
Yun remained in office to provide legitimacy to the regime, but resigned on March 22, 1962. Pak Chŏng Hŭi was the real power as chairman of the Supreme Council for National Reconstruction. Following pressure from the Kennedy administration in the United States, a civilian government was restored, with Pak narrowly winning the 1963 election as the candidate of the newly created Democratic Republican Party over Yun, candidate of the Civil Rule Party. He was re-elected in 1967, again defeating Yun by a narrow margin.
