FIGURE 22.1 Global Comparison: Casualties of the First World War Historians disagree about the number of casualties in World War I. Record keeping in many countries was only rudimentary. Moreover, the destructive nature of the war meant that countless soldiers were wholly obliterated or instantly buried. This chart shows estimates of casualties (the combined number of wounded and killed soldiers) per country. The percentage listed with each casualty figure represents the portion of soldiers mobilized who became casualties. However approximate, these figures make clear that the conflict that raged from 1914 to 1918 was a truly catastrophic world war. Although soldiers came from almost every part of the globe, the human devastation was not evenly distributed. Which country suffered the most casualties? Which country suffered the greatest percentage of casualties? What do you think was the principal reason that the United States suffered a smaller percentage of casualties than most other nations?
