In London, Paris and Washington, the abolitionist movement was gathering momentum. After the slave rebellion in Santo Domingo, and facing the public opinion’s growing outrage, the major European powers abolished the trans-Atlantic trade in 1807. Yet Europe, in the midst of the industrial revolution, could not do without the slave workforce. To satisfy its needs in raw materials, it pushed further the frontiers of slavery and turned a blind eye on the new forms of human exploitation in Brazil, the United States and Africa. At a time when legal trade was finally prohibited, the deportation of African captives would explode, and become more important than ever. Within 50 years, nearly 2.5 million were deported.
