The correct answer is A. The French Revolution affected the French colony of Saint-Domingue, today's Haiti, inspired the Haitian people to mount their own rebellion for independence.
Inspired by the French Revolution of 1789, from 1791 to 1803 General Toussaint Louverture, a former slave and leader of the only successful slave rebellion, with the help of the United States, managed to get the Spanish and British out of what is now Haiti.
The struggle for independence in Saint-Domingue took place in several stages: in the first stage, the big landowners, slaves, merchants and poor whites shared their solidarity with the revolutionary movement that had broken out in the metropolis and formed a local assembly, that claimed the end of the colonial pact. In a second stage, the free mulattos began to support the metropolitan revolution, believing that with that they would obtain from the whites residing in the colony the full equality of rights for free men, independently of race. In 1790 the white planters repressed the claims of the free, and these had no alternative but to ally the insurgents.
On August 14, 1791, a Boukman voodoo priest ceremony was held in Bois-Cayman, which is considered the starting point of the Haitian Revolution. In November of the same year, tens of thousands of slaves revolted. The long emancipation process had as protagonist François Dominique Toussaint-Louverture, who declared the abolition of slavery, and who between 1793 and 1802 led the Haitian revolution with sagacity, confronting Spanish, English and French, until his capture, exile and death in France.
In 1803, Jean Jacques Dessalines definitively defeated the French troops at the Battle of Vertierres and in 1804 declared the independence of the country, which he called with the old name of Haiti, and proclaimed himself emperor.
