Created in 1861 and first awarded in March 25, 1863 during the American Civil War, this highest United States military decoration is presented by the United States government to a member of the armed forces or to their family. 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. No one can receive a Medal of Honor for having acted under orders, no matter how heroically they carried out those orders, for the medal is reserved strictly for those who act of their own accord and out of complete selflessness. More than 3,500 Medals of Honor have been awarded in total.

In 1990, the United States Congress designated March 25th of each year as National Medal of Honor Day, a day dedicated to Medal of Honor recipients. This award is equivalent to the United Kingdom’s Victoria Cross award.

Based solely on the sept surnames of Clan Donnachaidh, the following forty-five U.S. military service members have been awarded the Medal of Honor. Eight of these awards were made posthumously.
