Book excerpt: From Tahrir Square to Occupy, from the Red Shirts in Thailand to the Teachers in Oaxaca, protest camps are a highly visible feature of social movements' activism across the world. They are spaces where people come together to imagine alternative worlds and articulate contentious politics, often in confrontation with the state. Drawing on over fifty different protest camps from around the world over the past fifty years, this book offers a ground-breaking and detailed investigation into protest camps from a global perspective - a story that, until now, has remained untold. Taking the reader on a journey across different cultural, political and geographical landscapes of protest, and drawing on a wealth of original interview material, the authors demonstrate that protest camps are unique spaces in which activists can enact radical and often experiential forms of democratic politics.
