Although the slave trade to Brazil did not end until 1850, and slavery itself lasted until 1888, the practice of freeing slaves had been common from the time of first colonization by the Portuguese in the 16th century, and the children of freed women were born free. The result was that, by the time of a national census in 1872, there were 4.25 million free blacks and mulattos in the country, accounting for over three quarters of all those of African descent and two fifths of Brazil’s total population. To understand the willingness of Brazilian slave owners to free so many one must first consider the general nature of Brazil’s social structure and the paradigms that ordered it. For most, society was not thought of as being made up of individuals equally protected in their rights and mobile in relationship to one another, but by castes, ranks, corporations, guilds, and brotherhoods, layered one atop another or arranged side by side. Almost everyone could feel superior to someone else, even if inferior to others. The nuanced distinctions of ranks somewhat restrained the threat to social order that free and freed blacks might otherwise have been thought to pose. “Free-and-equal” was not a phrase heard in Brazil. There is overwhelming evidence that race was an important variable affecting one’s position, and discrimination against blacks was widespread and constant. The government reinforced the prejudices of white Brazilians, acquiesced in maintaining a hierarchy based on color, and presented obstacles to the ambitions of free African Brazilians. Civil service positions were usually denied to them, regardless of their qualifications. Recruitment for the army was focused on the poor, that is, on African Brazilians. Yet, it is also true that many individuals found their way around those obstacles and rose to positions of some importance, for skin color was just one of the many characteristics to be considered. There are multiple examples of freeborn mulattos (and some freed and freeborn blacks) who succeeded in 19th-century Brazil. Some became doctors, pharmacists, journalists, and teachers. Others entered politics and rose to positions of real power. A few worked energetically to bring about the end of slavery.
