Brazil in the 19th century was a exportation only country. Our economy depended on the exportation of coffee and for it slaves were the best option (or at least that's what they thought), differently from the US, as the North didn't depend so much from the slavery as the South. Also, our process of ending the slavery were more political than bellicose and it was a gradual process. In 1850 it was approved the Eusébio de Queirós act, were it was prohibited to import more slaves from Africa; In the Paraguayan War many slaves were fighting, and the ones who didn't die, got their Independence; In 1871 the Ventre Livre act was approved, were the children of slaves weren't considered slaves from that date forward; In 1885 the Sexagenários act were approved, were the slaves older than 65 were freed; And finally in 1888 the Lei Áurea abolished slavery definitely, signed by Princess Isabel. But don't think that the abolishment of slavery here didn't had any consequences. Because of that, the coffee lords that were unhappy with it, together with the army, unhappy with the end of the Paraguayan War, in 1889 realized a Coup d'État that ended the monarchy and established an oligarchical republic (which, even though it is no longer oligarchic, lasts until today. But also isn't any better than the monarchy, in my opinion).
