Explanation:

The Haitian society was majorly made up of a slave population. Many of the slaves felt inequality and racial segregation under French control. Because of this, they rose up and fought for their rights through a revolution. The fight started between the "affranchis," emancipated slaves, and Europeans because the affranchis didn't follow the new law. It was followed by rebellion and a revolution which later on, freed the Haiti with the help of Jean-Jacques Dessalinis. It made the country the first republic to be led by a black person.
