1. Sugarcane: This was the most important crop, and Saint-Domingue was the world's largest producer of sugar in the 18th century. The sugar industry was extremely labor-intensive, requiring a large workforce of enslaved Africans.
2. Coffee: Coffee was another major export crop, grown on smaller plantations than those used for sugarcane.
3. Indigo: This dye plant was also a significant export, though less important than sugar or coffee.
It's important to remember that the cultivation and export of these crops relied heavily on the forced labor of enslaved people.
