According to the article "Slavery in Brazil," the abolition of slavery did not officially end slavery in Brazil until 1872. However, before that there had been several attempts by the abolition groups, activist, and revolutions to end slavery, one of the most significant one include a muslim uprising in 1837. It was lead by a muslim born ethnic group who revolted against slave owners in Bahai, this group included muslims and non-muslims, but there was also a large absence in Brazilian born slaves who often achieved freedom before any other slaves. This made it even more difficult to achieve a successful revolution in Brazil since Brazilian born slaves did not participate in uprisings. This was often a result of tension created by masters who favored Brazilian born slaves more than African slaves, they did not see a need to revolt against their masters because they experienced higher rates of manumissions. So not only was a unified rebellion hard to achieve in Bahai due to the regime but the social tension between Brazilian born descendants and African born slaves prevented the formation of a common slave identity. Brazils independence also lead to the emancipation of slavery in 1884, but was only achieved from the effects from the Grande Seca in 1877-1878, which increased water shortages in the northeast province of Ceara. This drought decreased cotton and sugar production forcing plantation owners to sell their slaves quickly as popular resistance and resentment grew as famine and food shortages began to spread. Additionally, influence from religious activist and political leaders who grew concerned with the slavery of indigenous groups and Africans helped move forward the abolishment of slavery with the end of the sugar trade from Brazil to Britain. This eventually lead to the official end of slavery in 1888 when the golden act was passed, thus the institution had began to decline. In conclusion, Brazil was the last nation to abolish slavery having estimated to have imported roughly 4 million slaves during that time. So while this institution has now ended the history of slavery in brazil is still prevalent in Brazilian culture and society today.
