Enslaved Africans in Saint-Domingue, led by Dutty Boukman, held a Vodou ceremony that became a pivotal act of resistance. This gathering sparked a mass uprising against slavery, marking the beginning of the Haitian Revolution.
Bois Caïman was the site of the first major meeting of enslaved Africans during which the first major slave insurrection of the Haitian Revolution was planned.
