When Haiti’s slaves fought for their independence (and won) against France, France required its former colony to pay “reparations” to the French government and French slaveholders for the “theft” of their slaves. Costing billions of dollars in today’s money, it was financed by French banks and the American Citibank. The debt was only paid off in 1947. Having to continually send money out of the country has been a major factor in maintaining Haitian poverty over the past two centuries.
France, by the way, continues to refuse considering repaying the reparations back to Haiti.
