According to the Korean War historical records, by the end of the decade, two new states had formed on the peninsula. In the South, the anti-communist dictator Syngman Rhee (1875-1965) enjoyed the reluctant support of the American government.
The Korean war occurred between North Korea and South Korea around 1950 to 1953.
During this period, South Korea was supported by the United Nations, majorly the United States, while the Soviet Union and China supported North Korea.
In the North, the communist dictator Kim Il Sung (1912-1994) enjoyed the slightly more enthusiastic support of the Soviets.
