For well over a century, humanitarians and their organizations have used photographic imagery and the latest media technologies to raise public awareness and funds to alleviate human suffering. This volume examines the historical evolution of what we today call "humanitarian photography" - the mobilization of photography in the service of humanitarian initiatives across state boundaries - and asks how we can account for the shift from the fitful and debated use of photography for humanitarian purposes in the late nineteenth century to our current situation in which photographers market themselves as "humanitarian photographers." This book is the first to investigate how humanitarian photography emerged and how it operated in diverse political, institutional, and social contexts, bringing together more than a dozen scholars working on the history of humanitarianism, international organizations and nongovernmental organizations, and visual culture in Africa, Asia, the Middle East, Europe, and the United States. Based on original archival research and informed by current historical and theoretical approaches, the chapters explore the history of the mobilization of images and emotions in the globalization of humanitarian agendas up to the present.
