The nation's highest award for valor was first introduced exclusively for sailors and Marines, while the Army rejected the medal as a bad idea.
But six months after it was introduced in 1861, the Army changed its tune and authorized the Medal of Honor for soldiers. Since its creation, more than 3,400 military personnel have received the medal, which is awarded for "conspicuous gallantry and intrepidity at the risk of life above and beyond the call of duty."
In a documentary called "Medal of Honor - The History," there are many more insights into how the medal came to fruition during the Civil War, its different designs, and how the requirements for receiving it changed over time. Interestingly enough, the idea of "stolen valor" frauds that today's veterans continue to fight was a problem even in the late 1800s, which led recipients to form the Medal of Honor Legion.
The film, which is narrated by Gary Sinise, also explores the actions of some of the heroes who received the medal. It's worth a watch.
