The decolonization of the Americas occurred over several centuries as most of the countries in the Americas gained their independence from European rule. The American Revolution was the first in the Americas, and the British defeat in the American Revolutionary War (1775–83) was a victory against a great power, aided by France and Spain, Britain's enemies. The French Revolution in Europe followed, and collectively these events had profound effects on the Spanish, Portuguese, and French colonies in the Americas. A revolutionary wave followed, resulting in the creation of several independent countries in Latin America. The Haitian Revolution (1791–1804), perhaps one of the most successful slave uprisings in history, resulted in the independence of the French slave colony of Saint-Domingue (now Haiti). The Peninsular War with France, which resulted from the Napoleonic occupation of Spain, caused Spanish Creoles in Spanish America to question their allegiance to Spain, stoking independence movements that culminated in various Spanish American wars of independence (1808–33), which were primarily fought between opposing groups of colonists and only secondarily against Spanish forces. At the same time, the Portuguese monarchy fled to Brazil during the French invasion of Portugal. After the royal court returned to Lisbon, the prince regent, Pedro, remained in Brazil and in 1822 successfully declared himself emperor of a newly independent Brazilian Empire.
Spain would lose all three of its remaining Caribbean colonies by the end of the 1800s. Santo Domingo declared its first independence from Spain in 1821. The independent state was renamed Republic of Spanish Haiti. Haiti conquered the region shortly afterwards in 1822. Two decades later, in 1844, independence was proclaimed for the second time, and the Dominican Republic was established. This triggered the Dominican War of Independence (1844–56). In 1861, however, Spain regained control of the territory, and the colony was reestablished. The Dominican Restoration War (1863–65), the second war of liberation, led to the second independence from Spain, and the Dominican Republic's third and final independence. Cuba fought for independence from Spain in the Ten Years' War (1868–78) and Little War (1879–80) and finally the Cuban War of Independence (1895–98). American intervention in 1898 became the Spanish–American War and resulted in the United States gaining Puerto Rico, Guam (which are still U.S. territories), and the Philippine Islands in the Pacific Ocean. Under military occupation, Cuba became a U.S. protectorate until its independence in 1902.
