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.
1987 South Korean presidential election
Nearly a month later on 10 June, mass protests broke out as Roh Tae Woo was announced successor to the presidency as the then chair of the DJP. The public nature of the announcement and the death of a university student who was tortured by the police triggered protests across Korea. In the following weeks, multiple protests were held, and on 29 June, the DJP candidate Roh Tae Woo capitulated to demands for constitutional amendments, proposing an eight-point plan"." It included the following concessions:
The new constitutional amendment was ratified by the National Assembly on 12 October, and was submitted to a referendum to the South Korean public on 27 October. 93% of voters cast ballots in favor of the amendment, which permitted the direct, democratic election of the 6th President of South Korea.
