“In this Trade, No Places are Held:” Involvement of Portuguese slave traders in the slave trade between Africa and Brazil (1818-1828)

Abstract

Between 1818 and 1828, the Portuguese Board of Trade (known locally as the Junta do Comércio) gave ships departing from Lisbon permission to traffic African slaves to Brazil. This authorization was the result of international treaties signed between the monarchies of Portugal and Britain in 1815 and 1817. This article discusses the context in which the slave traders functioned, the ways in which they received license to trade, and how the source documents from the Portuguese Board of Trade during this period provide important information on the slave traders based in Portuguese harbors.
