The Medal of Honor was created during the American Civil War and is the highest military decoration presented by the United States government to a member of its armed forces. The recipient must have distinguished themselves at the risk of their own life above and beyond the call of duty in action against an enemy of the United States. Due to the nature of this medal, it is commonly presented posthumously.
The President of the United States, in the name of the United States Congress, has awarded more than 3520 Medals of Honor including 19 second awards to the nation's soldiers, sailors, airmen, marines, and coast guardsmen since the decoration's creation in 1861.
