Looking at travelogues, ethnographic monographs, consular reports, diaries and letters, sketches, photography and more, Burroughs examines eyewitness travel reports of atrocities committed in European-funded slave regimes in the Congo Free State, Portuguese West Africa, and the Putumayo district of the Amazon rainforest during the late-nineteenth and early-twentieth centuries. As Burroughs articulates, as well as bringing home to readers ongoing brutalities, eyewitness narratives importantly contributed to debates on humanitarianism, trade, colonialism, and race and racial prejudice in late Victorian and Edwardian Britain.
