German Angst analyzes the relationship of fear and democracy in postwar West Germany. While fear has historically been associated with authoritarian regimes, the book highlights the role of fear and anxiety in a democratizing society: these emotions undermined democracy and stabilized it at the same time. By taking seriously postwar Germans’ uncertainties about the future, the book challenges dominant linear and teleological narratives of postwar West German “success.” It highlights the prospective function of memories of war and defeat, of National Socialism and the Holocaust. Fears and anxieties derived from memories of a catastrophic past that postwar Germans projected into the future. Based on case studies from the 1940s to the present, the book provides a new interpretive synthesis of the Federal Republic. It tells the history of the Federal Republic as a series of recurring crises, in which specific fears and anxieties emerged, served a variety of political functions, and then again abated. Drawing on recent interdisciplinary insights of emotion studies, the book transcends the dichotomy of “reason” and “emotion.” Fear and anxiety were not exclusively irrational and dysfunctional but served important roles in postwar democracy. These emotions sensitized postwar Germans to the dangers of an authoritarian transformation, and they also served as the emotional engine of the environmental and peace movements. The book also provides an original analysis of the emotional basis of right-wing populism in Germany today, and it explores the possibilities of a democratic politics of emotion.
