General of the Army Douglas MacArthur, GCB (January 26, 1880 – April 5, 1964) was an American general, United Nations general, and Field Marshal of the Philippine Army. He was a Chief of Staff of the United States Army during the 1930s and later played a prominent role in the Pacific theater of World War II. He was a highly decorated US soldier of the war, receiving the Medal of Honor for his early service in the Philippines and on the Bataan Peninsula. He was designated to command the proposed invasion of Japan in November 1945. When that was no longer necessary, he officially accepted the nation's surrender on September 2, 1945.
MacArthur oversaw the Occupation of Japan from 1945 to 1951. Although criticized for protecting Emperor Hirohito and the imperial family from prosecution for war crimes, MacArthur is credited with implementing far-reaching democratic reforms in that country. He led the United Nations Command forces defending South Korea against the North Korean invasion from 1950 to 1951. On April 11, 1951 MacArthur was removed from command by President Harry S. Truman for publicly disagreeing with Truman's Korean War Policy.
MacArthur fought in three major wars (World War I, World War II, Korean War) and was one of only five men ever to rise to the rank of General of the Army.
