Just to see exactly what we are talking about, here is another version of this "historical fact" making the rounds in Evangelical circles:
It is a matter of well-documented historical fact that the nation of Haiti
was dedicated to Satan 200 years ago. On August 14, 1791, a group of houngans
(voodoo priests), led by a former slave houngan named Boukman, made a pact with the Devil at a place called Bois-Caiman. All present vowed to exterminate all of the white Frenchmen on the island. They sacrificed a black pig in a voodoo ritual at which hundreds of slaves drank the pig's blood. In this ritual, Boukman asked Satan
for his help in liberating Haiti from the French. In exchange, the voodoo
priests offered to give the country to Satan for 200 years and swore to serve
him. On January 1, 1804, the nation of Haiti was born and thus began a new
But is it "a matter of well documented fact?" Here is the report of a Dr. Gelin, a Haitian scientist and minister, who researched this question because, as he notes, "the idea that Haiti was dedicated to Satan prior to its independence is a very serious and profound statement with potentially grave consequences for its people in terms of how they are perceived by others or how the whole nation is understood outside its borders." I appreciate that his concern is the consequences for Haiti in terms of its image abroad and not the "spiritual" ramifications of the curse itself, because that is quite a reasonable concern. You can read his whole article, but, in short, he found no historical proof for it. Furthermore, as a believing Christian he joined a group who decided to go to the fabled spot of this Satanic dedication and undo any curses that might have been activated, just in case. So, why didn't Robertson know this? Why was he not informed by God that the cursed had been lifted? Must have his wires crossed.
I have searched through several sources of Haitian history and found no proof of this pact with the devil. It was not the devil who set the slaves in Haiti free from their tyrannical French masters, it was some damned fine guerrilla fighting on the part of the Haitians themselves. In fact, in an era of increasing worldwide dominance by European military forces, the former slaves assembled a very effective military that repulsed three different European invasions (British, French, and Spanish.) The nation's troubles since then are due to a number of different factors, from American and European meddling to an acute lack of education, skills, and resources, all historically documented, and none attributable to Satan.
