Syngman Rhee
Syngman Rhee (, ; Lunisolar calendar , 1875 – July 19, 1965) was a South Korean politician, the first and the last Head of State of the Provisional Government of the Republic of Korea, and President of South Korea from 1948 to 1960. His three-term presidency of South Korea (August 1948 to April 1960) was strongly affected by Cold War tensions on the Korean Peninsula.

From 1948, South Korea was governed by President Syngman Rhee, an anti-Communist who used the Korean War to consolidate a monopoly on political power in the republic. Rhee represented the interests of a conservative ruling class, the so-called "liberation aristocrats" who had risen to positions of influence under American occupation. These "liberation aristocrats" formed the bulk of the political class, encompassing both Rhee's supporters and his rivals in the Democratic Party, which advanced a vision of society broadly similar to his own. Rhee eliminated any significant source of real opposition, securing for example the execution of Cho Bong-am, who had campaigned against him in the presidential elections of 1956 on a platform of peaceful reunification and had attracted some 30% of the vote, an unacceptably high level of support for an opposition candidate.
