From the condemnation of protest to skepticism of religious ecstasy, radical movement has been defined by freedoms and restrictions relative to class conflict, national policy, and colonialism. In this book, author Kelina Gotman examines choreographies of unrest, rethinking the modern formation of choreomania, a fantastical concept across scientific disciplines used to designate the spontaneous and uncontrolled movements of crowds. In these misformations of body politics, prejudices against spontaneity unravel, suggesting widespread anxieties about impulsiveness and irregularity. In tandem with dialogues of the erratic, Gotman makes use of histories of nineteenth-century control which identify the period as one of increasing regimentation. As she notes, constraints on movement signal constraints on political power and agency and on individuals' capacity to shift their allegiances, inhabiting more hospitable terrains. In each chapter, Gotman confronts the many ways choreomania functions as an extension of colonialism, dismissing expressive bodies as mentally and physically infected others.Through her research, Gotman unearths the many instances of choreomania that represent collective efforts to escape social tyranny inflicted by the upper class.
