After addressing Germaine de Stäel’s ‘invention’ of European Romanticism in On Literature and On Germany, the introductory chapter explains the editorial choices behind the collection, including its expansive time frame, European focus, and comparative method. It then surveys Lord Byron’s continental reception to demonstrate the utility of a pan-European approach. Although extremely familiar, the case of Byron and of Byronism is of central importance to the history of European Romanticism because of the European role that it gave to British literature, but also because it brings to the fore some common problems raised when using Romanticism as a critical category. The next section looks at how literary historians have addressed these problems, then discusses some of the period’s most salient features. The final part provides a chapter by chapter synopsis in order to help readers navigate the volume.
