This is the story of the evolution of the citizen army throughout Western nations during the nineteenth century and up through World War I. The French Revolution had brought to Europe the concept of military service as a citizen responsibility. Until then, armies and navies had been the province of the upper classes and of mercenaries, with authoritarian governments firmly in place that held little connection to the common person. As more democratic and republican governments developed during the 1800s, military service became not only a citizen's obligation, but for many, an honor. By the time of World War I, men and women-in more limited roles-were becoming willing to risk their lives for the goals of their countries.
