The photographs contained in the archives of the International Committee of the Red Cross tell the story of people caught up in conflict, both victims and relief workers. They are the record of a century marked by deeds of extreme heroism as well as utmost infamy, bringing hope as well as despair. This book reflects the evolution of international humanitarian law and roll of visual images in humanitarian action. Based on photo reports from the time of the Crimean War up to the Second World War, the first part of the book traces the history of the Geneva Conventions. The second part draws on mostly unpublished photographs to illustrate wars since 1950 - in Korea, Vietnam, Biafra, the Middle East, Rwanda, Bosnia-Herzegovina, and many other theatres of conflict.
