This collection of essays explores activist performances, all connected to theater or performance training, that have changed the Americas—from Canada to the Southern Cone. Through the study of specific examples from numerous countries, the authors of this volume demonstrate a crucial, shared outlook: they affirm that ordinary people change the direction of history through performance. This project offers concrete, compelling cases that emulate the modus operandi of people like historian Howard Zinn. In the same spirit, the chapters treat marginal groups whose stories underscore the potentially unstoppable and transformative power of united, embodied voices. This book will be of great interest to students and scholars of theatre, performance, art and politics.
