Haitian Revolution

Mass uprising begins on Saint-Domingue’s Northern Plain

About 200 trusted plantation figures — coachmen, drivers, domestic servants — reportedly met to plan the rising, while slaveholders relied on those same people to run the estates.

The night of 22 August 1791

The coordinated mass uprising of enslaved people broke out in full force on Saint-Domingue's Northern Plain on the night of 22 August 1791. Dutty Boukman, a coachman on the Clément estate, launched the rebellion in the parish of Acul, and it spread through the plantation districts around Cap-Français.

The rising had been planned by enslaved organizers from numerous plantations. Boukman, Jean-François, Georges Biassou and Jeannot were among its early leaders.

Why the calendars disagree

The 21 August date attached to this entry probably conflates a preliminary or religious gathering — and possibly premature plantation fires — with the mass uprising itself.

Carolyn Fick places the probable Bois Caïman ceremony on 21 August and the full outbreak on 22 August; UNESCO commemorates the beginning as the night of 22–23 August; another university overview describes the coordinated revolt as the night of 21–22 August.

The date, location and details of the Bois Caïman ceremony are themselves contested, because the evidence combines a small number of contemporary references with later oral tradition.

What the first weeks destroyed

A well-attested meeting near the Lenormand de Mézy estate on 14 August had fixed the plans, with about 200 plantation representatives reported present.

Plantations were attacked and burned as the uprising expanded; a Cambridge University Press study reports that 184 sugar plantations were destroyed in the ensuing weeks.

Toussaint Louverture, the figure most often made the face of the revolution, is not securely documented as the commander who launched it — his name does not appear in surviving documents until later in 1791.

The rising unfolded overnight and across multiple plantations, so sources differ according to whether they date its planning, first fires, full mobilization or dawn discovery.
