Syngman Rhee
On July 20, 1948, Rhee was elected president of the Republic of Korea in the South Korean presidential election, 1948 with 92.3% of the vote; the second candidate, Kim Gu, received 6.7% of the vote. On August 15, the Republic of Korea was formally established in South Korea and Rhee was inaugurated as the first President of the Republic of Korea. The next month, on September 9, the north also proclaimed statehood as the Democratic People's Republic of Korea. Rhee himself had been an independence activist, and his relations with the "chinilpa" Korean elites who had collaborated with the Japanese were, in the words of the South Korean historian Kyung Moon Hwang, often "contentious," but in the end an understanding was reached in which, in exchange for their support, Rhee would not purge the elites. In particular, the Koreans who had served in the colonial-era National Police, whom the Americans had retained after August 1945, were promised by Rhee that their jobs would not be threatened by him. Upon independence in 1948, 53% of South Korean police officers were men who had served in the National Police during the Japanese occupation.
1971 South Korean presidential election
By tradition, the most senior members of the party leadership were supposed to run for president. It was assumed that either former Korea University president Yu Jin-oh, the sitting party chair Yu Jin-san, or former president Yun Po-sun would be chosen for the party's candidate. However, the norm was broken by lawmaker Kim Young-sam, who was only in his early forties, when he declared his bid for the New Democratic nomination for president on 8 November, 1969. He was followed by Kim Dae-jung and Lee Cheol-seung, both prominent politicians in their forties. The party leadership tried to discourage the three candidates at first, but later conceded that it was now time for the new generation to take over. Lee Cheol-seung withdrew his bid and endorsed Kim Dae-jung after the party leadership, including Chairman Yu Jin-san, announced they would be backing Kim Young-sam.
