Who Dat Nation Facts: the Haitian Revolt Doubled the Size of the United States Thru the Louisiana Purchase
When Napoleon Bonaparte had tried and FAILED to re-conquer Saint-Domingue territory and re-establish slavery under his brother-in-law Charles Leclerc, he offered the U.S. all of Louisiana instead of just New Orleans, at an expense of $15 million, equivalent to about $219 million in present day terms.
The Purchase encompassed all or part of 14 current U.S. states and two Canadian provinces which doubled the size of the United States, comprises around 23% of current U.S. territory.

I Absolutely think that you're on point with your idea of using the Haitian Revolution for Black History Teaching. Our children should know all of our history, because we are all connected so it (Black History) shouldn't be limited to what happened in America. I find that teaching about others and being able to link it back is more interesting. I wonder if the State of Louisiana offers French as a second language in its elementary schools? That would be nice for the kids if they did.
