'This is a remarkable work of historical scholarship that compels us to rethink what we know about the Amazon rubber boom and Britain's role within it. The horrors of the Putumayo atrocities are known and have long stood as one of the darkest chapters in the history of the Amazon rubber boom. Yet the prevailing narrative has often portrayed these crimes as the isolated excesses of a single company rather than evidence of a broader system of exploitation. Drawing on diaries, correspondence, and company records, this groundbreaking study challenges that assumption. By reconstructing the day-to-day operations of the British-owned Tambopata Rubber Syndicate between 1907 and 1913, Nic Madge exposes the direct involvement of British managers in the enslavement, abuse, and coercion of Indigenous workers through the enganche por deudas bonded labor system. Coercion, bonded labor, and violence against Indigenous peoples were embedded in the everyday operations of a British-owned enterprise. As Madge says, "Historians may debate whether it was chattel slavery, debt peonage or a contemporary form of slavery, but to the indigenous people enslaved by the Syndicate those distinctions were academic. They made no difference to the oppression and brutality that they suffered.

" He's 100% right. By reconstructing life at the Tambopata Rubber Syndicate's remote barracas with exceptional archival precision, the book restores the voices and experiences of Indigenous workers while exposing the human cost of imperial capitalism. Rich in archival detail and compelling in its human focus, this book transforms our understanding of British participation in Amazonian rubber extraction. A major contribution to the histories of empire, capitalism, Indigenous peoples, and human rights, it compels readers to confront the enduring human costs of imperial commerce.'
