After more than three hundred years of Spanish rule, the Dominican people declared independence in November 1821. The leader of the independence movement, José Núñez de Cáceres, intended the Dominican nation to unite with the country of Gran Colombia, but the newly independent Dominicans were forcefully annexed by Haiti in February 1822. Independence came 22 years later in 1844, after victory in the Dominican War of Independence. Over the next 72 years, the Dominican Republic experienced mostly civil wars (financed with loans from European merchants), several failed invasions by its neighbour, Haiti, and brief return to Spanish colonial status, before permanently ousting the Spanish during the Dominican War of Restoration of 1863–1865. During this period, two presidents were assassinated (Ulises Heureaux in 1899 and Ramón Cáceres in 1911).
