The letter, dated September 19, 1857, was signed by José Thomaz Nabuco de Araújo, then Minister of Justice of the Empire of Brazil. In it, the minister informs the provincial authorities about ships suspected of participating in the illegal trafficking of Africans, even after the enactment of the Eusébio de Queirós Law (1850), which had officially prohibited the importation of enslaved people. The tone of the letter is administrative and legal, requesting greater vigilance and strict enforcement of the law against those involved in this clandestine trade.

The author of the letter was the father of Joaquim Nabuco (1849–1910), one of the most prominent figures in the Brazilian abolitionist movement. While the father was a respected politician, jurist, and slave owner, his son would dedicate his life to fighting against this institution, becoming the most influential voice of abolitionism in Brazil. This contrast reveals a striking paradox: within the same family, the common practice of the slave-owning elite coexists with the moral and political consciousness that would lead to the campaign for the abolition of slavery in the next generation.

This document is important because it symbolizes a moment of historical transition. It shows how, in the 1850s, the imperial government attempted to repress illegal trafficking without questioning the slave system itself. At the same time, the connection to Joaquim Nabuco gives the letter a symbolic and almost premonitory value: written by the slave-owning father who enforced the law against trafficking, it anticipates, in a way, the transformative role of his son, who, decades later, would be one of the main architects of the abolition of slavery in Brazil.
