The division of Hispaniola between France and Spain in 1697 recognized a reality with which neither the Kings nor their Revolutionary successors were happy. Although the population of Spanish Santo Domingo was perhaps one-fourth that of French Saint-Domingue, this did not prevent Charles IV of Spain from launching an invasion of the French side of the island in 1793, attempting to take advantage of the chaos sparked by the French Revolution (1789–99).[7] Although the Spanish military effort went well on Hispaniola, it did not so in Europe.
