Events leading to the Korean War: 1945-1950
August 1945 Korea is divided at the 38th Parallel.
After the Japanese surrender in 1945, both the Soviet Union and the United States sent troops to demobilize the Japanese troops that were still in Korea. Two inexperienced American colonels chose the 38th parallel because it was easy to find on a map. The Soviet Union dealt with the Japanese in North Korea and the United States would do the same in the South. The problem was that dividing Korea at the 38th parallel was not based on any geographical, cultural, or political lines.
September 1947 Korea remains divided.
The Soviet Union and the United States could not agree on the fate of the two Koreas, so the issue was brought up at the United Nations. The Soviet Union wanted the United States to leave when they did. Because North Korea did not send any representatives, the two Koreas remained divided.
August 1948 The government of North Korea is established.
North Korea is known officially as the Democratic People’s Republic of Korea.

Kim Il Sung becomes the first Premier of North Korea.
Kim Il Sung (1912-1994) was the chairman of the People’s Committee in North Korea from 1945, and when North Korea established its own government Kim Il Sung became its premier. He was trained in the Soviet Union. Kim Il Sung remained in power until his death, and his son, Kim Jong Il, took his place.
September 1948 The government of South Korea is established.
South Korea is now the Republic of Korea. The United Nations sees South Korea as the government of the entire Korean Peninsula.

Syngman Rhee is elected President.
Syngman Rhee (March 26, 1875-July 19, 1965) was elected the first president of the Republic of Korea. He had a doctorate degree from Princeton University and was a very staunch anti-communist. He served as president from 1948 until 1960.
