The riches of the Caribbean depended on Europeans' taste for sugar, which plantation owners traded for provisions from North America and manufactured goods from European countries. Starting in the 1730s, French engineers constructed complex irrigation systems to increase sugarcane production. By the 1740s Saint-Domingue, together with Jamaica, had become the main supplier of the world's sugar. Sugar production depended on extensive manual labor provided by enslaved Africans in the harsh Saint-Domingue colonial plantation economy. The white planters who derived their wealth from the sale of sugar knew they were outnumbered by slaves by a factor of more than ten and lived in fear of slave rebellion.[2]
In 1758, the white landowners began passing legislation that set restrictions on the rights of other groups of people until a rigid caste system was defined. Most historians have classified the people of the era into three groups. One was the white colonists, or blancs. A second was the free blacks (usually mixed-race, known as mulattoes or gens de couleur, free people of color). These tended to be educated, literate and often served in the army or as administrators on plantations. Many were children of white planters and slave mothers. The males often received education or artisan training, sometimes received property from their fathers, and freedom. The third group, outnumbering the others by a ratio of ten to one, was made up of mostly African-born slaves. A high rate of mortality among them meant that new slaves were being continually imported. They spoke a patois of French and West African languages known as Creole, which was also used by native mulattoes and whites for communication with the workers.[3]
