South Korea
Despite the initial plan of a unified Korea in the 1943 Cairo Declaration, escalating Cold War antagonism between the Soviet Union and the United States eventually led to the establishment of separate governments, each with its own ideology, leading to the division of Korea into two political entities in 1948: North Korea and South Korea. In the South, Syngman Rhee, an opponent of communism, who had been backed and appointed by the United States as head of the provisional government, won the first presidential elections of the newly declared Republic of Korea in May. In the North, however, a former anti-Japanese guerrilla and communist activist, Kim Il-sung was appointed premier of the Democratic People's Republic of Korea in September.
