On another note, I wonder what happens with Saint-Domingue/Haiti ITTL? The Haitian Revolution never happens ITTL, but there's no way that the massive slave system could be maintained there long-term. It was both the most profitable colony for any European colonial power, but also a living hell for most of the inhabitants, and it's probably a powderkeg. However, I've already gone through the entire 19th Century when a slave revolt was most likely, and even without the Haitian Revolution forcing the colonial powers to reconsider slavery in the Caribbean, I don't see slavery surviving all the way to 1920.
