The document summarizes the key events of the Korean War from 1945-1953. After World War 2, Korea was divided along the 38th parallel, with the Soviet Union occupying the north and the United States occupying the south. In 1950, North Korea invaded South Korea, leading the United Nations to intervene on behalf of South Korea. Fighting continued for three years until an armistice was signed in 1953, leaving the two Koreas still divided along the original border. The human cost of the war was high for both sides.
