What role did divisions in saint-domingues society play in the events of the haitian revolution

The saint domingue society was stratified as white colonists, or blancs on top, who owned most of the property. The gens de couleur libres were next who were light-skinned and dark-skinned blacks. In 1789 The Declaration of the Rights of Man and the Citizen gave the right to vote for the gens de couleur libres which was opposed by the blancs that led to the slave revolt in 1791. Also the population of the third division of the society who were black-skinned black slaves grew to half a million which as in the ratio 10:1 with the blancs. The fugitive slaves who were called Maroons grouped themselves and attacked the blancs.
