Spanish area at the end of the 18th century.
France came to own the island in 1795, when by the Peace of Basel Spain ceded Santo Domingo as a consequence of the French Revolutionary Wars. At the time, Saint-Domingue's slaves, led by Toussaint Louverture, were in revolt against France. In 1801 they captured Santo Domingo, thus controlling the entire island; but in 1802 an army sent by Napoleon captured Toussaint Louverture and sent him to France as prisoner. However, Toussaint Louverture's lieutenants, and yellow fever, succeeded in expelling the French again from Saint-Domingue, which in 1804 the rebels made independent as the Republic of Haiti. Eastwards, France continued to rule Spanish Santo Domingo.

He requested the new state's admission to Simón Bolívar's republic of Gran Colombia, but Haitian forces, led by Jean-Pierre Boyer, invaded just nine weeks later, in February 1822.

Boyer also placed more emphasis on cash crops grown on large plantations, reformed the tax system, and allowed foreign trade. The new system was widely opposed by Dominican farmers, although it produced a boom in sugar and
