It is probably a huge rabbit hole, but I find it highly suspect the poorest country in the Americas is also the blackest.
The wikipedia article is rather short.
I learnt about this in history, Haiti were done dirty. All the Western powers refused to trade with them and refused to recognise Haiti. They already went into debt for the weapons they bought to fight off the French and were still straddled with reparations.
Then in the 1910s, the US marines took Haiti's gold reserves off them. Five years later, they invade Haiti again just to take control of their banks and other financial institutions.
Then in 2004, when Haiti's elected president asked France to pay them back, he got overthrown in a coup. France, as a P5 member of the UN , refused to let UN peacekeepers intervene until they got pressured by the US.
