This book provides fresh perspectives on a key period in the history of humanitarianism. Drawing on economic, cultural, social and diplomatic perspectives, it explores the scale and meaning of humanitarianism in the era of the Great War. Foregrounding the local and global dimensions of the humanitarian responses, it interrogates the entanglement of humanitarian and political interests and uncovers the motivations and agency of aid donors, relief workers and recipients. The chapters probe the limits of humanitarian engagement in a period of unprecedented violence and suffering and evaluate its long-term impact on humanitarian action.
