On April 11, 1951, President Harry Truman relieved General Douglas MacArthur of his command over the US Army in the Far East. The general superseded his orders from the president, publicly disagreeing with Truman's policies in the Korean War, and even trying to provoke an all-out war with China.
Truman fired MacArthur for insubordination, a controversial move at the time. The bull-headed general was replaced in Korea by Gen. Matthew Ridgeway.
