The Eusébio de Queirós Law targets the Atlantic slave trade

← Back to Dashboard
📅 4 September 1850 📍 Brazil

On 4 September 1850, Law no. 581 strengthened the imperial state’s authority to suppress the landing of enslaved Africans brought into Brazil by sea. It came after decades of treaty promises and continued illegal trafficking. This measure attacked the transatlantic supply route, not slavery within Brazil: people already enslaved remained property under imperial law, and domestic buying, selling, and forced labor continued. Enforcement also served state-building and diplomatic interests; it should not be mistaken for emancipation.
