The Purple Heart is a United States military decoration awarded in the name of the President to those wounded or killed while serving, on or after April 5, 1917, with the U.S. military. With its forerunner, the Badge of Military Merit, which took the form of a heart made of purple cloth, the Purple Heart is the oldest military award still given to U.S. military members – the only earlier award being the obsolete Fidelity Medallion. The National Purple Heart Hall of Honor is located in New Windsor, New York.
