The Korean War

In 25 June 1950, the communist North Korean army, supplied by China and the Soviet Union, crossed the 38th parallel and invaded South Korea.

In 1948, the Republic of Korea and the Democratic People's Republic of Korea were established, practically they were divided two different nations in Korean peninsula. Kim Il-sung, the leader of the North Korea, wanted to reunify with the use of armed force even before the two nations were established, so China and Soviet's military assistance was precondition.

In 29th June 1949, U.S. Army completed evacuation except the military advisory group, and that gave Kim ill-sung the crucial motivation to start a war. 

The Korean War, started by a surprise attack of North Korea in 25th June 1950, showed a preponderance of North Korea.

In September 1950, the Operation Chromite turned the tide of the war, but the UN forces' going north cross the 38th parallel caused Chinese auxiliary troops took a part in the Korean war.

In July 1953, even though, Syngman Rhee, the first Korean president, opposed a ceasefire, military armistice agreement was sign by UN forces, China and North Korea, finally the Korean War which continued about 3years was ended.
