THIS BRIEF ESSAY is not intended to be a systematic comparison of the impact of defeat on German society following the two World Wars. Such a comparison would require a book, perhaps two. Rather, it is more of a reflection, drawn from work on research projects in the two postwar periods. The main focus will be on how Germans perceived defeat after each war and how these perceptions, combined with certain concrete postwar conditions, shaped subsequent political developments.' In comparing Germany in 1918 and 1945, one is immediately struck by the differing magnitude of physical destruction suffered by the country and the changed role of military occupation. Both physical destruction and military occupation were limited after 1918 but extensive after 1945. These facts are obvious and have some obvious consequences; at the same time a closer examination of the interrelationship of these two truisms will, I hope, provide some new perspectives, nuances, and implications for the study of the two postwar eras. In contrast to 1945, it was easy in 1918 for Germans to imagine that they were still undefeated. World War I ended with German troops in foreign lands; there was no fighting in Germany; and official propaganda proclaiming victory on all fronts was not substantially undermined by counterdata from outside the country.
