Although long overshadowed by the far more destructive Second World War, it was World War I (then known as the Great War) that first gave humanity a bloody taste of large-scale, industrialized warfare. Indeed, the unresolved conflicts of the First World War is what largely gave rise to the second.
All that aside, the amount of death wrought by this aptly proclaimed “War to End All Wars” is staggering, as the following chart from The Economist soberingly displays. I’ll let the numbers speak for themselves.
An entire generation was ground up in a senseless war that everyone thought would be over in no time. Every single one of those men was a distinct human being with his own identity, personality, dreams, fears, and loved ones. It’s hard to believe tens of millions more would join them just two decades or so later — and many more have since, albeit in far less visible conflicts.
