Question: Which early leader of the Haitian Revolution conducted a secret ceremony during which the first major slave insurrection was planned in 1791?

<P0-S0> François-Dominique Toussaint Louverture (] 20 May 1743 – 7 April 1803), also known as Toussaint L'Ouverture or Toussaint Bréda, was the best-known leader of the Haitian Revolution. <P0-S1>  His military and political acumen saved the gains of the first Black insurrection in November 1791. <P0-S2>  He first fought for the Spanish against the French; then for France against Spain and Great Britain; and finally, for Saint-Domingue against Napoleonic France. <P0-S3>  He then helped transform the insurgency into a revolutionary movement, which by 1800 had turned Saint-Domingue, the most prosperous slave colony of the time, into the first free colonial society to have explicitly rejected race as the basis of social ranking. <SEP> <P1-S0>  Once Napoleon had lost his control of the land holding in the Caribbean to the Haitian rebellion, he felt that the French territory in the southern part of the United States was useless to the French Empire. <P1-S1>  The US even went as far as to refuse acknowledgement of Haitian independence until 1862, which was during the heat of the North American civil war; coincidentally the main causal factor for the war between the states was slavery. <P1-S2>  An extremely beneficial aspect and real estate triumph that resulted from the Haitian Revolution and impacted the United States was the Louisiana Purchase. <P1-S3>  The Haitian Revolution of 1804 impacted the United States of America, led by Thomas Jefferson, instilling fear of racial instability in the US, and the possible problematic effect the revolution could have on the early foreign relations and trade between the US and the new independent Haiti. <P1-S4>  The second major impact that the Haitian Revolution had on the United States was on early foreign relations and trade that had been conducted with Haiti. <P1-S5>  Haiti was the main producer of the United States supply of sugar and coffee, and once the Haitian slave population had broken from slavery, the US was reluctant to continue trade with them in fear that they would upset the French and the Southern slaveholders. <P1-S6>  Thomas Jefferson realized that the Haitian Revolution had the potential to cause an upheaval against slavery in the US not only by the slaves themselves, but by white abolitionists as well. <P1-S7>  They realized that they would need to seek an opportunity to stop the tyranny that was being placed upon them, thus they took a stand and revolted. <P1-S8>  The United States had conducted trade and commerce with the Haitian island under French rule during the eighteenth century. <P1-S9>  The US was only interested in the New Orleans area; however, the revolution enabled the sale of the entire territory west of the Mississippi River for around $15 million. <P1-S10>  Southern slaveholders feared that the revolt might spread from the island of Hispaniola to the slave plantations of the Southern United States. <P1-S11>  But there were anti-slavery advocates in northern cities who believed that consistency with the principles of the American Revolution — life, liberty and equality for all—demanded that the U.S. support the slave insurgents. <P1-S12>  This purchase more than doubled the United States’ territory. <P1-S13>  The primary goal of the US was to maintain social order in the country, so the United States attempted to suppress the Haitian Revolution. <P1-S14> The Haitian Revolution provoked mixed reactions in the United States. <SEP> <P2-S0> Bois Caïman (Haitian Creole: "Bwa Kayiman" ) is the site of the Vodou ceremony during which the first major slave insurrection of the Haitian Revolution was planned. <P2-S1>  On the night of August 14, 1791, representative slaves from nearby plantations gathered to participate in a secret ceremony conducted in the woods by nearby Le Cap in the French colony of Saint-Domingue. <P2-S2>  Presided over by Dutty Boukman, a prominent slave leader and Vodou priest, the ceremony served as both a religious ritual and strategic meeting as conspirators met and planned a revolt against the ruling white planters of the colony's wealthy Northern Plain. <SEP> <P3-S0> Dutty Boukman (also known as Boukman Dutty) (died 7 November 1791) was an African man, enslaved in Jamaica and later in Haiti. <P3-S1>  He is considered both a maroon leader and Vodou hougan (priest) and was an early leader of the Haitian Revolution.
