German Angst analyses the relationship between fear and democracy in postwar West Germany. While fear and anxiety have historically been associated with authoritarian regimes, Frank Biess demonstrates the ambivalent role of these emotions in a democratizing society: in West Germany, fear and anxiety both undermined democracy and stabilized it. By taking seriously postwar Germans’ uncertainties about the future, this study challenges dominant linear andteleological narratives of postwar West German ‘success’, highlighting the prospective function of memories of war, National Socialism, and the Holocaust. Postwar Germans projected fears and anxieties that they derived from memories of a catastrophic past into the future. Based on case studies from the 1940s to the present, German Angst provides a new interpretive synthesis of the Federal Republic. It tells the history of the Federal Republic as a series of cyclical crises in which specific fears and anxieties emerged, served a variety of political functions, and then again abated. Drawing on recent interdisciplinary insights generated by the field of emotion studies, Biess’s study transcends the dichotomy of ‘reason’ and ‘emotion’. Fear and anxietywere 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 emotional engines of new social movements, including the environmental and peace movements. German Angst 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.
