Book excerpt: This book examines the connection between affects, mobilisation, and political transformation. Offering unique insights into the affective and emotional dynamics of occupied Tahrir and Taksim Squares, this book builds a novel understanding of urban mass protests and their capacity to “travel” across time and space. Its Midān Moment concept breaks new ground in affect and emotion studies with a focus on political transformation in Egypt and Turkey. It is based on empirically grounded research which covers the 2011 and 2013 uprisings and their authoritarian aftermath. This book will appeal to scholars and students interested in affect and emotion studies in a range of disciplinary areas, including political science, sociology, anthropology, area studies, cultural studies, gender studies, and postcolonial studies.
