Origins of Blacks in Brazil The Africans brought to Brazil belonged to two major groups: the West African and the Bantu people. The West Africans mostly belong to the Yoruba people, who became known as the "nagô". The word derives from ànàgó, a derogatory term used by the Dahomey to refer to Yoruba-speaking people. The Dahomey enslaved and sold large numbers of Yoruba, largely of Oyo heritage. Slaves descended from the Yoruba are strongly associated with the Candomblé religious tradition. Other slaves belonged to the Fon people and other neighboring ethnic groups. Bantu people were mostly brought from present-day Angola and the Congo, most belonging to the Bakongo or Ambundu ethnic groups. Bantu slaves were also taken from the Shona kingdoms of Zimbabwe and coastal Mozambique. They were sent in large scale to Rio de Janeiro, Minas Gerais, and Northeastern Brazil. Gilberto Freyre noted the major differences between these groups. Some Sudanese peoples, such as Hausa, Fula and others, were Islamic and spoke Arabic and many of them could read and write in this language. Muslim slaves were brought from northern Mozambique. Freyre noted that many slaves were better educated than their masters, because many Muslim slaves were literate in Arabic, while many Portuguese Brazilian masters could not read or write in Portuguese. These slaves of greater Arab and Berber influence were largely sent to Bahia. These Muslim slaves, known as Malê in Brazil, produced one of the greatest slave revolts in the Americas, known as the Malê Revolt, when in 1835 they tried to take control of Salvador, until then the largest city of the American continent and all of the New World. Despite the large influx of Islamic slaves, most of the slaves in Brazil were brought from the Bantu regions of the Atlantic coast of Africa where today Congo and Angola are located, and also from Mozambique. In general, these people lived in tribes, kingdoms or city-states. The people from Congo had developed agriculture, raised livestock, domesticated animals such as goat, pig, chicken and dog and produced sculpture in wood. Some groups from Angola were nomadic and did not know agriculture. Abolition of slavery According to Petrônio Domingues, by 1887 the slave struggles pointed to a real possibility of widespread insurrection. On 23 October, in São Paulo,
