Answer:
I found something about this on Wikipedia, I will write the link but also give some leading marks that might help you in elaborating your answer.
https://en.wikipedia.org/wiki/Saint-Domingue
Explanation:
"Saint-Domingue became known as the "Pearl of the Antilles" — one of the richest colonies in the world in the 18th-century French empire, was the greatest jewel in imperial France's mercantile crown."
"The economy of Saint-Domingue became focused on slave-based agricultural plantations."
"Thus, the income and the taxes from slave-based sugar production became a major source of the French budget."
"The first sugar windmill was built in 1685."
"Prior to the Seven Years' War (1756–1763), the economy of Saint-Domingue gradually expanded, with sugar and, later, coffee becoming important export crops."
"By the 1780s, Saint-Domingue produced about 40 percent of all the sugar and 60 percent of all the coffee consumed in Europe."
"This single colony, roughly the size of Hawaii or Belgium, produced more sugar and coffee than all of the British West Indies colonies combined, generating enormous revenue for the French government and enhancing its power."
I hope this helps!
