This is the first book to examine the shifting relationship between humanitarianism and the expansion, consolidation and postcolonial transformation of the Anglophone world across three centuries, from the antislavery campaign of the late eighteenth century to the role of NGOs balancing humanitarianism and human rights in the late twentieth century. Contributors explore the trade-offs between humane concern and the altered context of colonial and postcolonial realpolitik. They also showcase an array of methodologies and sources with which to explore the relationship between humanitarianism and colonialism. These range from the biography of material objects to interviews as well as more conventional archival enquiry. They also include work with and for Indigenous people whose family histories have been defined in large part by 'humanitarian' interventions.
