Around 1772, Romaine-la-Prophétesse acquired a plantation named Trou Coffy in the department (likely in what is now Fondwa), becoming a prominent cofeee grower and trader.[4] In 1791 and 1792, during the early Haitian Revolution, Romaine led some thirteen thousand slaves and rebels in freeing slaves from and burning the provinces plantations and briefly controlling two major cities, Léogâne and Jacmel.[5][6][7][8]
