The article analyses the unification of the political experiences of the three major nineteenth-century New World slave societies (United States, Cuba, and Brazil) after the rise of the Anglo-American abolitionist alliance in the 1830s. Describing the political framework of those three zones, it shows how they reacted to the Anti-Slavery International abolitionism in an integrated and cooperative way, something that can be called the Proslavery International. Finally, it examines why this interaction has not evolved to an official platform of its respective governments. The Proslavery International disappearance occurred with the impact of the American Civil War (1861-1865) in the Brazilian and the Spanish Empire slave systems.
