Violent conflicts between white colonists and black slaves were common in Saint-Domingue. Bands of runaway slaves, known as maroons (marrons), entrenched themselves in bastions in the colony's mountains and forests, from which they harried white-owned plantations both to secure provisions and weaponry and to avenge themselves against the inhabitants. As their numbers grew, these bands, sometimes consisting of thousands of people, began to carry out hit-and-run attacks throughout the colony. This guerrilla warfare, however, lacked centralized organization and leadership. The most famous maroon leader was François Macandal, whose six-year rebellion (1751-57) left an estimated 6,000 dead. Reportedly a boko, or voodoo sorcerer, Macandal drew from African traditions and religions to motivate his followers. The French burned him at the stake in Cap Français in 1758. Popular accounts of his execution that say the stake snapped during his execution have enhanced his legendary stature.

Many Haitians point to the maroons' attacks as the first manifestation of a revolt against French rule and the slaveholding system. The attacks certainly presaged the 1791 slave rebellion, which evolved into the Haitian Revolution. They also marked the beginning of a martial tradition for blacks, just as service in the colonial militia had done for the gens de couleur. The maroons, however, seemed incapable of staging a broad-based insurrection on their own. Although challenged and vexed by the maroons' actions, colonial authorities effectively repelled the attacks, especially with help from the gens de couleur, who were probably forced into cooperating.

The arrangement that enabled the whites and the landed gens de couleur to preserve the stability of the slaveholding system was unstable. In an economic sense, the system worked for both groups. The gens de couleur, however, had aspirations beyond the accumulation of goods. They desired equality with white colonists, and many of them desired power. The events set in motion in 1789 by the French Revolution shook up, and eventually shattered, the arrangement.

The National Assembly in Paris required the white Colonial Assembly to grant suffrage to the landed and tax-paying gens de couleur. (The white colonists had had a history of ignoring French efforts to improve the lot of the black and the mulatto populations.) The Assembly refused, leading to the first mulatto rebellion in Saint-Domingue. The rebellion, led by Vincent Ogé in 1790, failed when the white militia reinforced itself with a corps of black volunteers. (The white elite was constantly prepared to use racial tension between blacks and mulattoes to advantage.) Ogé's rebellion was a sign of broader unrest in Saint-Domingue.

A slave rebellion of 1791 finally toppled the colony. Launched in August of that year, the revolt represented the culmination of a protracted conspiracy among black leaders. According to accounts of the rebellion that have been told through the years, François-Dominique Toussaint Louverture helped plot the uprising, although this claim has never been substantiated. Among the rebellion's leaders were Boukman, a maroon and voodoo houngan (priest); Georges Biassou, who later made Toussaint his aide; Jean-François, who subsequently commanded forces, along with Biassou and Toussaint, under the Spanish flag; and Jeannot, the bloodthirstiest of them all. These leaders sealed their compact with a voodoo ceremony conducted by Boukman in the Bois Cayman (Alligator Woods) in early August 1791. On August 22, a little more than a week after the ceremony, the uprising of their black followers began.

The carnage that the slaves wreaked in northern settlements, such as Acul, Limbé, Flaville, and Le Normand, revealed the simmering fury of an oppressed people. The bands of slaves slaughtered every white person they encountered. As their standard, they carried a pike with the carcass of an impaled white baby. Accounts of the rebellion describe widespread torching of property, fields, factories, and anything else that belonged to, or served, slaveholders. The inferno is said to have burned almost continuously for months.

News of the slaves' uprising quickly reached Cap Français. Reprisals against nonwhites were swift and every bit as brutal as the atrocities committed by the slaves. Although outnumbered, the inhabitants of Le Cap (the local diminutive for Cap Français) were well-armed and prepared to defend themselves against the tens of thousands of blacks who descended upon the port city. Despite their voodoo-inspired heroism, the ex-slaves fell in large numbers to the colonists' firepower and were forced to withdraw. The rebellion left an estimated 10,000 blacks and 2,000 whites dead and more than 1,000 plantations sacked and razed.

Even though it failed, the slave rebellion at Cap Français set in motion events that culminated in the Haitian Revolution. Mulatto forces under the capable leadership of André Rigaud, Alexandre Pétion, and others clashed with white militiamen in the west and the south (where, once again, whites recruited black slaves to their cause). Sympathy with the Republican cause in France inspired the mulattoes. Sentiment in the National Assembly vacillated, but it finally favored the enfranchisement of gens de couleur and the enforcement of equal rights. Whites, who had had little respect for royal governance in the past, now rallied behind the Bourbons and rejected the radical egalitarian notions of the French revolutionaries. Commissioners from the French Republic, dispatched in 1792 to Saint-Domingue, pledged their limited support to the gens de couleur in the midst of an increasingly anarchic situation. In various regions of the colony, black slaves rebelled against white colonists, mulattoes battled white levies, and black royalists opposed both whites and mulattoes. Foreign interventionists found these unstable conditions irresistible; Spanish and British involvement in the unrest in Saint-Domingue opened yet another chapter in the revolution.
