The ending of the slave trade in Brazil has a number of consequences.

First, because labor needs increase in Rio de Janeiro and São Paulo as the world demand for coffee rises, Northeastern planters sell their surplus slaves to Southern growers

In addition, Parliament had passed laws encouraging European immigration, as well as the Land Law of 1850.

Second, ending the slave trade frees capital that can now be used for investment in transport and industrial enterprises.

Third, it ensures that Britain does not interfere in Brazil's military intervention to end the rule in Buenos Aires of Juan Manuel de Rosas (president of Argentina, 1829-33, 1835-52).
