Answer: French colony of Saint-Domingue
Saint-Domingue used the French revolution as an inspiration to gain its own independence.
Its leaders François Dominique Toussaint-Louverture and Jean-Jacques Dessalines led the revolution against the slavery in Saint-Domingue.
The colony had been an important port in the Americas for goods and products (primary sugar) that flowed from France to Europe. It became the richest and most prosperous colony in the West Indies and gained independence.
