Topic 5.2 Notes – Nationalism and Revolutions in the Period from 1750 to 1900
What Nationalism and Revolution Changed
This period changed the source of political authority. For centuries, people were usually subjects of a monarch. Now they were increasingly described as citizens who had rights and could judge whether a government deserved obedience.
The ideas came from the Enlightenment, but ideas alone did not start revolutions. Revolts usually happened when those ideas mixed with taxes, debt, inequality, slavery, colonial limits, or foreign invasion.
Political ideas to know together
- Natural rights means people have rights just for being human, such as liberty or property.
- Popular sovereignty means political power comes from the people, not from divine right.
- Social contract means government exists to protect rights. If it fails, people can replace it.
- Republicanism means representative government instead of hereditary monarchy.
- Liberalism in the 1800s meant constitutions, civil liberties, equality before the law, and private property. It did not always mean full democracy.
Nation and nationalism
- State means a government ruling a territory.
- Nation means a people who share identity through language, religion, customs, history, or land.
- Nation-state means a state that claims to represent one nation.
- Nationalism means loyalty to that nation and often the belief it should rule itself.
Nationalism could unify places like Italy and Germany, break apart empires like the Ottoman Empire, inspire anti-colonial movements, or be pushed from above by governments through schools, flags, and armies.
A constant exam pattern is this gap between universal ideals and limited inclusion. Rights were often restricted by race, gender, class, and property.
Why Revolutions Broke Out and How They Spread
These revolutions connect best when you see four causes working together:
- Intellectual causes
Enlightenment thinkers attacked monarchy, privilege, and arbitrary rule. - Structural grievances
People were angry about taxation, slavery, racial hierarchy, estate privilege, creole exclusion, and colonial exploitation. - Political and fiscal crises
War debt, food shortages, elite conflict, and invasion weakened governments. - Diffusion
Revolutions inspired other revolutions through print, travelers, soldiers, and famous documents.
Chain of influence
- American Revolution showed a colony could defeat an empire and form a republic.
- French Revolution spread ideas of citizenship, equality, and anti-privilege politics.
- Haitian Revolution showed enslaved people could overthrow slavery and colonial rule.
- Latin American revolutions borrowed from all three and grew stronger when Napoleon invaded Spain and Portugal.
By about 1830, that chain of influence had helped reshape much of the Americas into newly independent states, especially in Latin America.

Standard documents
| Document | Main idea |
|---|---|
| Declaration of Independence | People can break from a government that violates their rights |
| Declaration of the Rights of Man and of the Citizen | Sovereignty rests in the nation and citizens are equal before the law |
| Bolívar’s Letter from Jamaica | Spanish American independence is justified and necessary |
The Atlantic Revolutions
American Revolution
British debt after the Seven Years’ War led to new taxes and tighter control. Colonists answered with “no taxation without representation.” The Declaration of Independence in 1776 turned protest into a formal claim for separation. The result was U.S. independence and a constitutional republic. The limits matter just as much as the success. Slavery remained, women were excluded, and Indigenous land loss continued.
French Revolution
France faced debt, unequal estates, bourgeois resentment, bread shortages, and a weak monarchy. Key moments ran in sequence:
- Estates-General met in 1789
- National Assembly claimed to represent the nation
- Rights of Man attacked privilege
- Republic declared in 1792
- Louis XVI executed in 1793
- Reign of Terror showed radical instability
Napoleon Bonaparte
Napoleon kept some revolutionary gains, especially legal equality for men and the Napoleonic Code, but he also ruled as an authoritarian leader. His conquests spread reform and also sparked anti-French nationalism.
Haitian Revolution
Saint-Domingue was a brutally profitable slave colony built on plantation labor and racial hierarchy. Enslaved people rose in 1791. Toussaint Louverture became the best-known leader, and Jean-Jacques Dessalines helped finish the struggle. Haiti became independent in 1804, abolished slavery, and became the first independent Black republic.
Latin American independence
Creoles resented peninsular control, and Napoleon’s invasion of Iberia created the opening. Key leaders included Simón Bolívar, José de San Martín, Miguel Hidalgo, and José María Morelos. Bolívar helped create Gran Colombia, but it later fragmented. Brazil followed a different path when Pedro I declared independence in 1822 and kept a monarchy. Across Latin America, independence came, but creole elites usually stayed on top.
How Nationalism Reshaped States and Empires
Nationalism did not just overthrow rulers. It also built states and weakened empires.
Unification movements
- Italy
- Mazzini spread nationalist ideas, Cavour used diplomacy, and Garibaldi fought in the south. Piedmont-Sardinia led unification. The Kingdom of Italy formed in 1861, and Rome joined in 1870.
- Germany
- The Zollverein customs union built economic ties. Bismarck used diplomacy and war against Denmark, Austria, and France. The German Empire was proclaimed in 1871.
This map of Italy helps you see the patchwork of states nationalism pulled together during the 1800s.

Italian unification, 1815-1870
Nationalism against empires
- Greece revolted in 1821 and gained recognized independence in 1830.
- Balkan nationalisms in Serbia, Romania, and Bulgaria pushed for self-rule and gained autonomy or independence as Ottoman control weakened.
- Outside Europe, nationalism also appeared in the Philippines under José Rizal, in New Zealand through the Māori King Movement, and in Puerto Rico through Lola Rodríguez de Tió.
Governments using nationalism
States taught nationalism through schools, standardized language, flags, anthems, military conscription, and public ceremonies. Revolutionary France, unified Germany, unified Italy, and Ottomanism all used this strategy.
Effects and Limits of the Revolutionary Era
The biggest effects were new independent states in the Americas, the spread of constitutions and rights language, the unification of Italy and Germany, and weaker multiethnic empires. The revolutions of 1848 showed nationalism and liberalism still had power even when many uprisings failed.
The limits are just as testable. Rights stayed restricted by race, gender, class, and property. Slavery survived in many places after independence. Latin America often kept old social hierarchies under new rulers. Nationalism could unite a majority and exclude minorities at the same time.
