The newly arrived slaves who died before they even started toiling in Brazil’s mines were hauled to a mass grave nearby, their corpses left to decay amid piles of garbage. As imperial plantations flourished, diggers at the Cemitério dos Pretos Novos — Cemetery of New Blacks — crushed the bones of the dead, making way for thousands of new cadavers....
cholars say the scale of the slave trade here was staggering. Brazil received about 4.9 million slaves through the Atlantic trade, while mainland North America imported about 389,000 during the same period, according to the Trans-Atlantic Slave Trade Database, a project at Emory University.
Rio is believed to have imported more slaves than any other city in the Americas, outranking places like Charleston, S.C.; Kingston, Jamaica; and Salvador in northeast Brazil. Altogether, Rio received more than 1.8 million African slaves, or 21.5 percent of all slaves who landed in the Americas, said Mariana P. Candido, a historian at the University of Kansas.
