Answer :

Korea was conquered by Japan during World War II. At the end of the war, Korea was partitioned at the Thirty-eighth Parallel into democratic South Korea and communist North Korea. The Korean War (1950-1953) was a United Nations effort to assist South Korea, which had been invaded by the army of North Korea. The administration of Harry S. Truman had pressured the UN Security Council for a resolution to use military force-UN troops and ships, led by the United States-to defend South Korea.
