This book highlights newly-discovered and underutilized sources for the study of slavery and abolition. It features the contributions of scholars who work with Portuguese, Spanish, German, Dutch, and Swedish materials from Europe, Africa and Latin America. Their work draws on legal suits, merchant correspondence, Catholic sacramental records, and rare newspapers dating from the seventeenth through the nineteenth centuries. Essays cover the volume of the early South Atlantic slave trade; African and African-descended religious and cultural communities in Rio de Janeiro and the Spanish circum-Caribbean; Eurafrican trade alliances on the Gold Coast; and public participation in abolition in nineteenth-century Brazil. These essays change and enrich our understandings of slavery and its end in the Atlantic World. This book was originally published as a special issue of Slavery and Abolition.
