Korean War

1950-1953 war between North and South Korea

The Korean War, (Korean ;한국전잴/Russian ; Корейская Война/Chinese ; 朝鲜战争) also known as the Forgotten War, took place between 25 June 1950 and 27 July 1953 between the Republic of Korea (or South Korea), supported by the armed forces of several countries that were commanded by the United States;, and the Democratic People's Republic of Korea (or North Korea), supported by the People's Republic of China and the Soviet Union. The war began at 4:30 a.m. on June 25, 1950. The fighting stopped on July 27, 1953, after more than two million Koreans had been killed, mostly in the North.

Both sides blame each other for starting the war. The north, led by communist Kim Il-Sung, was helped mostly by People's Republic of China led Mao Zedong and the Soviet Union led by Joseph Stalin . There was medical support from East Germany (led by Walter Ulbricht),Hungary (led by Mátyás Rákosi), Romania (led by Gheorghe Gheorghiu-Dej), Czechoslovakia,(led by Klement Gottwald) and Poland (led by Bolesław Bierut) and Bulgaria . Other support came from Mongolia led by Khorloogiin Choibalsan (1895-1952) The south, led by nationalist Syngman Rhee, was helped by many countries in the United Nations, and especially by the United States.

The war ended on July 27, but the United States still keeps troops in South Korea in case North Korea ever invades again. Both Koreas are divided by the Korean Demilitarized Zone, which crosses the 38th parallel.

Origins and causesEdit

In 1910 10 year’s after the First Sino-Japanese War Japan occupied Korea under Japanese rule and was still ruling when World War II ended in 1945 . After Japan surrendered, the United States and the Soviet Union agreed to split Korea into two temporary occupation zones, with the Soviets occupying the North and the Americans occupying the South. It was at first meant to be only for a short time.

At the Moscow Conference of the Council of Foreign Ministers in December 1945, the Americans and the Soviets agreed on Korea having a provisional government, which would not last long. That became difficult because of the rise of the Cold War.[1]

The Cold War was an important cause in the Korean War. Relations between the two occupying powers were already bad, but when China became communist in October 1949, US President Harry Truman was very worried that other countries around China would go communist as well, such as Japan. The US Army was about one twelfth the size of five years earlier.[2] and Joseph Stalin had recently lost a Cold War dispute over the Berlin Blockade and subsequent airlift. Both powers argued mainly over fair border lines and the spread of communism.
