📅 8 August 1845 📍 Brazil

On 8 August 1845, Britain passed the Aberdeen Act, authorizing British courts to try slave-trading vessels and crews under its interpretation of existing treaty rights. The act followed Brazil’s failure to suppress the trade and British frustration with the 1826 convention. It increased external pressure and threatened Brazilian sovereignty, while serving Britain’s own imperial agenda. The measure targeted the trade; it did not emancipate the millions of people already enslaved in Brazil.
