The biggest stain in Brazilian history, worst than any dictatorship or wars and the main cause of most of our social problems was slavery. Brazil was the last country in America and the last of the Western world (if you consider Brazil western) to abolish slavery, in 1888, and the slavers were so strong that they eventually couped the government in the following year, with any plan to indenize the slaves being shelved.
However, something that it is quite interesting is that Portugal abolished slavery in 1791, when still had Brazil as a colony (Brazil became a united kingdom about 20 years later), so what if Portugal had extended the abolition of slavery to Brazil, as a direct order completely disregarding the will of the brazilian elites, could this work, or instead Brazil would be independent as a way to preserve slavery like the CSA did?
