Gabriel de Clieu brought coffee seedlings to Martinique in the Caribbean in 1720. Those sprouts flourished and 50 years later there were 18,680 coffee trees in Martinique enabling the spread of coffee cultivation to Saint-Domingue (Haiti), Mexico and other islands of the Caribbean. The French territory of Saint-Domingue saw coffee cultivated starting in 1734, and by 1788 supplied half the world's coffee. Coffee had a major influence on the geography of Latin America. The French colonial plantations relied heavily on African slave laborers. However, the dreadful conditions that the slaves worked in on coffee plantations were a factor in the soon-to-follow Haitian Revolution. The coffee industry never fully recovered there.
