Noronha e Brito believed that slave masters were too strict and petty for punishing their slaves with unnecessary rigor, forcing them to work too much, feeding them poorly, and giving them minimal leisure. For him, slaves were "uneasy" due to mistreatment. Therefore, he encouraged the festivities held by slaves, unlike their masters. The Count of Arcos chose to deal with slaves through deterrence. In his view, when the slaves practiced their religions, they would come into conflict with each other, since the African ethnic plurality was enormous, which was also reflected in Brazil. He believed this to be a better option than inducing the practice of Christianity among them, as that could lead to unity and possibly rebellions. The Count of Arcos also believed that slavery was a necessary evil that could be alleviated by making it more bearable for the slaves. It was with his support that the brotherhood of Barroquinha managed to build a noble hall attached to its temple. The temple also gained more equipment and increased in size. The meetings, which were prohibited by the previous governor, the Count of Ponte, became legal by the Count of Arcos and, therefore, had a substantial improvement even in their structures. His policy in dealing with slavery displeased the local nobles. They wrote a letter to the king to demonstrate their displeasures. During his rule, there were at least three slave revolts in the captaincy. In the letter, they mentioned that the rebels had achieved the union of various ethnic groups, contrary to the Count's policy that the free practice of their customs would separate them. They commented that the uprisings were violent, noting that 150 houses were burned by the rebels and more than 50 people were killed. They also asserted that slaves could not be treated well, as "fear and punishment are the only means of doing them well". The Count of Arcos paid little attention to the nobles. For him, the masters' fear and discontent was based on the very remorse they felt for daily mistreating their slaves. With this, the nobles held a meeting with the aim of removing Marcos de Noronha from power. Despite the support of the Military Commander of Bahia, brigadier
Felisberto Caldeira Brant, future Marquis of Barbacena, the nobles were not prepared to carry out a coup d'état. Brant proved to be a strong opponent of the Conde of Arcos on the slave issue, as he wrote to the court in Rio de Janeiro that the governor should change his guidelines and ban slave parties, which were known as
batuques. He claimed that the Count of Arcos seemed unable to "write or say a syllable against blacks". His discontent reached the level of personally going to Rio de Janeiro, seat of the court, to protest in favor of the slave owners in Bahia. There he obtained an order from the government with basic measures for the treatment of slaves. When Brant returned to Bahia, the Count of Arcos imprisoned him for a few days because of his audacity. Afterwards, the two reconciled to fight the Pernambuco Revolt of 1817, which demanded the independence of Brazil. His approach was peaceful so that the slaves would not rebel, but when they did they were harshly repressed. In one of the revolts that took place in the captaincy, four slaves were sentenced to death, others sentenced to public floggings, and 23 men - probably freed slaves - were deported to
Angola, to the Portuguese port of Benguela. More than 20 slaves died in prisons from mistreatment. == Pernambuco Revolt of 1817 ==
