"This book is the culmination of decades of careful research, and assumes an important place on a historiographical pitch steamrollered by an over-concentration on British perspectives." · European History Quarterly
"This work elucidates, with clear prose and abundant evidence, a new and important finding: the top slave trading nation of the nineteenth century did not act only upon British will, but developed its own antislavery attitudes within a nationalistic context." · Enterprise & Society
"His is a uniquely authoritative voice on abolition in Portugal, a far remove from the 'enlightened will of the masters' approach...that long dominated the historiography. The book is a spell-binding narrative with scholarship of the highest order. Marques is to be congratulated on breaking the silence surrounding the abolition of the slave trade of Portugal and bringing a Portuguese voice t6o international debates on abolition." · The International History Review
"[Marques] offers an important contribution not only for those interested in the Atlantic slave trade but also enriches generally the transnationally or globally oriented historiography. " · H-Net, Clio-online Portugal was the pioneer of the transatlantic slave trade, the ruler of both Brazil and Angola - the all time champions of that trade -, and one of the last western countries to decree the abolition of slaving institutions. Paradoxically, and in spite of the overwhelming number of works devoted to the problems of slavery produced in recent decades, little was known about the way Portugal dealt with the twilight of the age of slavery and, most of all, with abolitionism. This book offers the first study of the abolition of the Portuguese slave trade, covering the period from the end of the eighteenth century to the mid-1860s, and bringing to life a dark and silenced corner in the history of the odious commerce. Based on a thorough examination of Portuguese and British historical sources - most of them never used before -, and on his awareness of the international scholarship in the field in which he writes, it investigates not only the Portuguese pro and anti-abolitionist attitudes but also the underlying ideologies, and whether and how those attitudes and ideologies changed over time and in the light of events in the political, economic and social spheres.
