# Eusébio de Queirós

Eusébio de Queirós Coutinho Matoso da Câmara (Luanda, 1812 – Rio de Janeiro, May 7, 1868) was a Brazilian magistrate and politician, Minister of Justice (1848–1852) and author of one of the most important laws of the Empire of Brazil, the Eusébio de Queirós Law, which suppressed the slave trade and paved the way for its eventual eradication. He was also responsible for the Commercial Code of 1850 that still remains partly in force today.

## Early life

He was the son of Eusébio de Queirós Coutinho da Silva and Catarina Matoso de Queirós Câmara. Both his father and grandfather served as superintendent magistrate of Colonial Angola. When he was only three years old, his family moved to Rio de Janeiro, where the court of the prince regent of Portugal, future king John VI, was located. After exercising several positions as judge, his father was chosen to be a representative of Angola to the Constituent Cortes of 1820 (Constituent Assembly) in 1821, but soon joined the movement for the Independence of Brazil and was a member of the first Supreme Court of Justice of Brazil.

## Political career

Eusébio de Queirós graduated with a bachelor's degree in legal and social sciences from the Faculty of Law in Olinda in 1832.$^{:67}$ He was elected provincial representative as a Conservative for Rio de Janeiro in 1838. In 1842 he was elected to the National Assembly representing Rio de Janeiro, and was re-elected for four more terms.
He was Chief of Police in Rio de Janeiro. He also served as Minister of Justice from 1848 to 1852 under the government of Prime Minister Pedro de Araújo Lima. The position at that time included the command of the National Guard, the Ecclesiastical Affairs (nomination of bishops, payment of priests and bishops) and the appointment of judges and chiefs of police.$^{:28–29}$
He was the author of one of the most important laws of the empire, the Eusébio de Queirós Law, promulgated on September 4, 1850, which prohibited the slave trade from Africa to Brazil. Although there had been similar laws before, it was under him as Minister of Justice that the Brazilian government for the first time acted effectively against the slave trade to Brazil (previous laws having been passed mainly to placate the British, who were committed to ending the slave trade internationally). Since he had been Chief of Police in Rio de Janeiro, he knew each of the places where smuggled Africans could be hidden. He also had good connections with the Rio businessmen who trafficked slaves from Africa. Using his information and relationships, he acted with severity in repressing the prohibited traffic, ensuring that it ceased abruptly.
He steered through the law of June 25, 1850 enacting the first Commercial Code of Brazil. This remained in force until 2002 when the new Brazilian Civil Code incorporated Commercial Law. Until today, however, it remains in effect part of the Maritime Law of the Commercial Code of 1850.
He promulgated the Land Law which extinguished traditional land grants and obliged public lands to be acquired by open auction, but also prevented newly arrived immigrants from buying land. He deployed the first law-based penitentiary system in Brazil, dedicating long stretches of his ministerial reports to the subject. He also worked with Irineu Evangelista de Sousa to install the first gas lighting in Rio de Janeiro.
After serving as a minister, he was a judge, senator (1854) and member of the Council of State (1855). He was appointed Minister of the Supreme Court of Justice by decree of March 1, 1864. As this position was incompatible with that of State Councilor, he then asked for retirement, which was granted by Pedro II in a decree dated March 21, 1864. In the year of his death he resided in Rua Santa Teresa nº 9, in Rio de Janeiro.
