History · The 20th century
25 June 1950 – 27 July 1953
The first shooting war of the Cold War, fought under a United Nations flag
The war that began when North Korean forces crossed the 38th parallel on 25 June 1950 and ended, three years later, close to where it started. The United Nations Security Council authorised a defence of the South while the Soviet delegate was boycotting its meetings, and sixteen countries sent combat troops under American command. Douglas MacArthur's landing at Inchon in September 1950 reversed the invasion, but the advance towards the Yalu brought Chinese intervention in October and November and a second retreat. From mid-1951 the front stabilised near the parallel while armistice talks dragged on. The armistice signed at Panmunjom on 27 July 1953 created the demilitarised zone; no peace treaty has ever followed.
