The Atlantic Revolutions were a revolutionary wave in the late eighteenth and early nineteenth centuries. It was associated with the Atlantic World during the era from the 1770s to the 1820s.
It took place in both the Americas and Europe, including the United States, France and French-controlled Europe, Haiti, Ireland and Spanish America. There were smaller upheavals in Switzerland, Russia, and Brazil. The revolutionaries in each country knew of the others and to some degree were inspired by or emulated them.
Independence movements in the New World began with the American Revolution, 1775–1783, in which France, the Netherlands and Spain assisted the new United States of America as it secured independence from Britain. In the 1790s the Haitian Revolution broke out. With Spain tied down in European wars, the mainland Spanish colonies secured independence around 1820.
In long-term perspective, the revolutions were mostly successful. They spread widely the ideals of liberalism, republicanism, the overthrow of aristocracies, kings and established churches.
