Memorial Day is an American holiday started after the American Civil War, and is held on the last Monday of every May. It is very similar to Veterans Day, which is held on November 11th. Both holidays celebrate the men and women who have served in the armed forces, but Memorial Day takes it a step further and venerates those who died while in service.
Considering the cost in lives that our Civil War had, it is no wonder such a day of remembrance was implemented. If all of our casualties of wars were added up, from every war we've ever fought, over 50% of them would be from the Civil War alone. While I think it is very important for us to remember those who have died to keep this country safe and free, I think it is equally important to remember that we have killed more of our own than any foreign power has. United we stand.
