Answer

Slavery in Brazil began long before the first Portuguese settlement was established in 1532, as members of one tribe would enslave captured members of another.Later, colonists were heavily dependent on indigenous labor during the initial phases of settlement to maintain the subsistence economy, and natives were often captured by expeditions called bandeiras.

The importation of African slaves began midway through the 16th century, but the enslavement of indigenous peoples continued well into the 17th and 18th centuries.

Steps taken to abolish slavery were:

Jean-Baptiste Debret, a French painter who was active in Brazil in the first decades of the 19th century, started out by painting portraits of members of the Brazilian Imperial Family, but soon became concerned with the slavery of both blacks and the indigenous inhabitants. During the fifteen years Debret spent in Brazil, he concentrated not only on court rituals but the everyday life of slaves as well. His paintings (one of which appears on this page) helped draw attention to the subject in both Europe and Brazil itself.
The Clapham Sect, although their religious and political influence was more active in Spanish Latin America, were a group of evangelical reformers that campaigned during much of the 19th century for the United Kingdom to use its influence and power to stop the traffic of slaves to Brazil. Besides moral qualms, the low cost of slave-produced Brazilian sugar meant that British colonies in the West Indies were unable to match the market prices of Brazilian sugar, and each Briton was consuming 16 pounds (7 kg) of sugar a year by the 19th century. This combination led to intensive pressure from the British government for Brazil to end this practice, which it did by steps over three decades.
Slavery was not legally ended nationwide until 1888 by the Lei Áurea ("Golden Act"), a legal act promulgated on May 13 by Isabel, Princess Imperial of Brazil.
