Book excerpt: Staging Authority: Presentation and Power in Nineteenth-Century Europe is a comprehensive handbook on how the presentation, embodiment, and performance of authority changed in the long nineteenth century. It focuses on the diversification of authority: what new forms and expressions of authority arose in that critical century, how traditional authority figures responded and adapted to those changes, and how the public increasingly participated in constructing and validating authority. It pays particular attention to how spaces were transformed to offer new possibilities for the presentation of authority, and how the mediatization of presence affected traditional authority. The handbook’s fourteen chapters draw on innovative methodologies in cultural history and the aligned fields of the history of emotions, urban geography, persona studies, gender studies, media studies, and sound studies.
