How was the freedom won by the slaves in central america

I don't quite understand your question, but I think this is what you mean:

"Slavery was abolished in British Caribbean colonies from 1834, though slaves were forced to undertake a further 4 year period of apprenticeship before they were finally freed. The achievement of freedom is thus dated from 1 August 1838. Brazil was again the last country to emancipate all its slaves in 1888."

Hoped I helped!
