Considerable scholarship has traced the flows of captives from West Central Africa, especially the Kongo and Angola areas, and the Bights of Benin, Biafra and the Upper Guinea Coast. However, this book is the first work to consider the movement for the abolition of slavery in the seventeenth century as a unified endeavour in both the Old and New Worlds. This book has engaged with African abolition and the wider Atlantic network, including not only enslaved Africans but also New Christians and Indigenous Americans in the mid-seventeenth century. Anglophone and Lusophone scholars have paid little attention to the Black Atlantic abolitionist movement beyond the Americas, a topic that has been considered in depth here. Let me summarise my main findings.
