This chapter considers the origin and significance of three terms widely used to characterize a decadent periodization in Britain, the United States, and France: fin de siècle, Gilded Age, and Belle Époque. While these terms were used loosely, and in some cases retrospectively, to describe the last thirty years of the nineteenth century, they also highlight dominant social narratives of the period. These decades witnessed unprecedented economic growth, rapid technological progress, and relative peace following such crises as the Franco-Prussian War in Europe and the Civil War in the United States. However, the cultural products of decadence were more likely to emphasize millennial doom, nervous exhaustion, sexual perversion, and scientific failure, while the decadent style was seen as a novel way of expressing how it felt to live in an era in which the pace of modern life brought with it febrile cultural, social, and political change.
