Inspired by the French Revolution of 1789 and principles of the rights of man, the French settlers and free people of color pressed for greater political freedom and more civil rights. Tensions between these two groups led to conflict, as a militia of free-coloreds was set up in 1790 by Vincent Ogé, resulting in his capture, torture and execution. Sensing an opportunity, in August 1791 the first slave armies were established in northern Haiti under the leadership of Toussaint Louverture inspired by the Vodou ''houngan'' (priest) Boukman, and backed by the Spanish in Santo Domingo – soon a full-blown slave rebellion had broken out across the entire colony.
