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.
List of leaders of North Korea
The Constitution of North Korea has recognized the title "Supreme Leader" since 2009, when the Chairman of the National Defence Commission was formally designated as "the Supreme Leader of the Democratic People's Republic of Korea" (Korean: 조선민주주의인민공화국의 최고 지도자). It was slightly amended in 2012, with "Chairman" replaced by "First Chairman." It was further amended in 2016 to reflect the replacement of the NDC with the State Affairs Commission.Kim Jong-il died on 17 December 2011, but has since been posthumously named the "Eternal General Secretary". Thus his son and successor as leader, Kim Jong-un, was not given the title of General Secretary.
