Among all the nuances of Memorial Day that are debated by historians, it is important to note its origins in the Civil War.
With over 752,000 estimated casualties — 2.4 percent of the country's population in 1860 — almost every American family lost someone in that bloody war.
Thereby, when Memorial Day was established, every single American was remembering someone they loved getting killed in action. The cost of war was understood by the entire nation, and the burden shared by all.
