During the late 18th and early 19th centuries, major revolutions on both sides of the Atlantic occurred above all in the United States, France, Haiti, and across Spanish America, with related uprisings in places like Ireland and parts of the Polish–Lithuanian Commonwealth. These events are often grouped together as the “Atlantic Revolutions” or part of the broader “Age of Revolution.”

Key Atlantic revolution countries

  • United States – The American Revolution (roughly 1775–1783) created an independent republic out of Britain’s North American colonies and became an early model for later Atlantic revolutions.
  • France – The French Revolution (from 1789 into the early 1800s) overthrew the monarchy, triggered radical social and political change, and influenced movements across Europe and the Americas.
  • Haiti (then Saint‑Domingue) – Beginning in 1791, the Haitian Revolution was a massive slave uprising that abolished slavery in the colony and led to Haiti’s independence in 1804, the second independent state in the Americas.
  • Spanish America – A series of independence wars (c. 1810–1825) in territories that became Mexico, Colombia, Venezuela, Argentina, Chile and others broke most of Spain’s American empire away from European rule.

Other related uprisings

  • Ireland – The United Irishmen’s Rebellion in 1798 tried to establish an independent Irish republic, inspired in part by the American and French examples.
  • Polish–Lithuanian Commonwealth – Reformist upheavals and wars in the late 18th century, such as around the 1788–1792 period, are also counted within the wider wave of revolutions during the “Age of Revolution,” though they were less successful.

In classroom contexts, when asked “which countries on both sides of the Atlantic experienced revolutions during the late 18th and early 19th centuries,” the core expected answers are usually: the United States, France, Haiti, and the new nations emerging from Spanish American independence movements.
