What this lesson covers
In 1815 the diplomats at the Congress of Vienna tried to put Europe back the way it had been before the French Revolution. They failed, and the reason was an idea Napoleon's armies had carried across the continent: that a state should belong to a nation — a people bound by language, history, and culture — rather than to a dynasty that had inherited it.
Over the next sixty years that idea did two opposite things at once. It glued hundreds of separate German and Italian states into two powerful new countries, and it tore at empires like the Ottoman and the Austrian, where dozens of nationalities lived under a single crown. Meanwhile, in Japan, a version of the same idea toppled the shogun and produced a centralized state built to survive in a world of nation-states. This lesson explains the mechanism behind all of it — and why unification and fragmentation were two results of one force.

Where Nationalism Came From
Nationalism is the belief that a people sharing language, culture, history, and territory forms a nation, and that each nation deserves its own sovereign state. Before the French Revolution, loyalty ran to a monarch, a religion, or a local lord. The Revolution replaced the king's subjects with citizens of a French nation and mobilized them in a mass army — the levée en masse — that beat professional forces across Europe.
Napoleon then spread the idea in two ways, one intended and one not. He deliberately reorganized Europe: he abolished the thousand-year-old Holy Roman Empire, consolidated hundreds of German states into the Confederation of the Rhine, imposed uniform legal codes, and swept away feudal privileges. He also unintentionally provoked nationalism in the people he conquered. Spanish guerrillas, Prussian reformers, and Russian peasants resisted in the name of their own nations.
Romantic writers and scholars gave the movement its cultural content. The Grimm brothers collected German folktales, philologists standardized national languages, and historians dug up medieval heroes as national ancestors. Cheap printing and rising literacy — themselves products of industrialization — spread these stories to readers who had never met most of their supposed countrymen.
The Congress of Vienna, led by Metternich, restored legitimate monarchs and redrew borders to balance power, ignoring nationality entirely. Italians were handed back to Austria, Habsburgs, and the Pope; Germans got a loose Confederation of 39 states. That mismatch between where nations lived and where borders ran became the central political problem of the century, and it exploded in the Revolutions of 1848, when liberals and nationalists rose across Europe. Almost all of those risings failed — a failure that taught the next generation to pursue unity through power rather than idealism.

Italy and Germany: Unification From Above
After 1848 the leaders who actually built nation-states were conservatives using war and diplomacy, not revolutionaries manning barricades. Their approach is often called Realpolitik: policy based on practical calculation of power rather than ideology or sentiment.
In Italy, Giuseppe Mazzini's Young Italy had supplied the dream of a democratic republic since the 1830s, but Count Camillo di Cavour, prime minister of Piedmont-Sardinia, supplied the method. He modernized Piedmont's economy, joined the Crimean War to win a seat at the diplomatic table, and secured a secret promise of French help at Plombières in 1858. The 1859 war with Austria gained Lombardy; plebiscites brought in the central duchies. In 1860 Giuseppe Garibaldi and his thousand Red Shirts conquered Sicily and Naples, then handed the south to King Victor Emmanuel II rather than fight for a republic. The Kingdom of Italy was proclaimed in 1861, gaining Venetia in 1866 and Rome in 1870.
In Germany, the economic groundwork was the Zollverein, a Prussian-led customs union from 1834 that made trade German before politics did. Otto von Bismarck, Prussia's minister-president from 1862, declared that the great questions would be settled by iron and blood, and fought three short wars to prove it: against Denmark in 1864, Austria in 1866 (which expelled Austria from German affairs), and France in 1870–71. The German Empire was proclaimed in the Hall of Mirrors at Versailles in January 1871, with the Prussian king as Kaiser.
Students often assume the popular movements did the unifying. In both cases, popular nationalism supplied legitimacy while state power supplied the outcome.

The Same Idea That Cracked Empires
Nationalism unified where one nationality was spread across many small states. It did the reverse where many nationalities lived inside one large state — and the Ottoman and Habsburg empires were exactly that.
The Ottoman Empire governed Greeks, Serbs, Bulgarians, Romanians, Armenians, Arabs, and Turks under a system organized by religious community, not nationality. Greek revolutionaries rose in 1821, drew European sympathy and eventually Russian, British, and French intervention, and won independence recognized in 1830. Serbia gained autonomy and then independence; Romania and Bulgaria followed after the Russo-Turkish war of 1877–78. Ottoman reformers answered with the Tanzimat reforms, which promised legal equality for all subjects and tried to build an Ottoman civic identity, and later the Young Turks pushed constitutional and increasingly Turkish-nationalist programs. Neither stopped the losses, and Europeans began calling the empire the sick man of Europe while competing to inherit its territory.
The Austrian Empire faced Hungarians, Czechs, Poles, Croats, Serbs, Slovenes, Romanians, and Italians. After defeat by Prussia in 1866, the Habsburgs bought Hungarian loyalty with the Ausgleich, or Compromise, of 1867: a Dual Monarchy of Austria-Hungary sharing a monarch, army, and foreign policy but with separate parliaments. It satisfied one nationality and infuriated the Slavic peoples who got nothing, especially the South Slavs looking toward independent Serbia.
The misconception to avoid is treating unification and fragmentation as opposite forces. They are one principle — nation equals state — applied to different maps. In the Balkans, where the two empires met and populations were mixed, the principle guaranteed conflict, because no border could contain one nation only. Those unresolved claims are what made the region so dangerous by 1914.

Nationalism Beyond Europe: Meiji Japan
Nationalism was not only European. When Commodore Perry's American ships forced Japan open in 1853–54, the Tokugawa shogunate signed unequal treaties granting foreigners low tariffs and extraterritoriality. Samurai from Satsuma and Chōshū, rallying under the slogan sonnō jōi — revere the emperor, expel the barbarians — overthrew the shogun in 1868 and restored the Meiji emperor as the symbolic head of a united nation.
The new leaders quickly concluded that expelling foreigners was impossible; the way to preserve independence was to become a modern nation-state fast. The Charter Oath of 1868 promised assemblies and the search for knowledge throughout the world. In 1871 the domains were abolished and replaced with prefectures run from Tokyo, ending samurai autonomy. Universal male conscription in 1873 replaced the hereditary warrior class with a national army, and the samurai revolt against these changes was crushed in 1877. A national school system taught standard Japanese and loyalty to the emperor; the 1889 Meiji Constitution created a parliament while keeping real power with the emperor and his advisers. Japan borrowed deliberately and selectively — a German-style constitution and army, a British-style navy, French and American models for law and education.
The parallel with Germany is worth noticing. Both were latecomers that used a strong state to industrialize rapidly, both built conscript armies, both grafted a parliament onto monarchical authority, and both turned quickly to overseas expansion. Japan's victories over China in 1895 and Russia in 1905 showed that the nation-state model was not a European monopoly — a lesson colonized peoples across Asia and Africa noticed, and one that connects directly to the imperial rivalries of the next lesson.

Worked example
Your teacher gives you this excerpt from Bismarck's 1862 speech to the Prussian budget committee: "Not by speeches and majority decisions will the great questions of the day be decided — that was the great mistake of 1848 and 1849 — but by iron and blood." Using the document and your knowledge, explain what Bismarck rejected and how his approach actually produced German unification.
Step 1 — Identify the reference. "The great mistake of 1848 and 1849" points to the Frankfurt Parliament, where elected liberals debated a German constitution and offered the crown to the Prussian king, who refused it. The revolutions collapsed because the delegates had words but no army.
Step 2 — Name what is being rejected. Bismarck rejects liberal, parliamentary nationalism: the idea that unity can be negotiated by assemblies and majority votes. He is also speaking during a constitutional crisis in which the Prussian parliament refused to fund army expansion, so the speech defends governing without its consent.
Step 3 — Define his alternative. "Iron and blood" means industry and armed force — unification achieved by Prussian state power, with the monarchy and army in charge rather than elected nationalists.
Step 4 — Trace the evidence. The Danish War of 1864 gave Prussia Schleswig and a quarrel to use later. The Austro-Prussian War of 1866 took only seven weeks and pushed Austria out of German affairs, replacing the old Confederation with the Prussian-led North German Confederation. The Franco-Prussian War of 1870–71, provoked in part by Bismarck's edited Ems Dispatch, brought the southern states in on Prussia's side and ended with the empire proclaimed at Versailles in 1871.
Step 5 — State the consequence, since a complete answer goes past the narrative. Unification from above meant the new Germany had a parliament (the Reichstag) elected by universal male suffrage but a chancellor answerable only to the Kaiser, and an army outside civilian control. Nationalism was harnessed to conservative authority rather than to liberal democracy.

Practice questions
Which pairing best shows that 19th-century nationalism could both build and break states?
- The Zollverein of 1834 and the Congress of Vienna of 1815
- The German Empire proclaimed in 1871 and Greek independence won by 1830
- The Charter Oath of 1868 and the Meiji Constitution of 1889
- The Crimean War of 1853–56 and the Franco-Prussian War of 1870–71
Answer: The German Empire proclaimed in 1871 and Greek independence won by 1830
Germany shows nationalism assembling many small states of one nationality into a single country; Greece shows the same principle detaching one nationality from a multiethnic empire. The other pairings sit on one side of the story only: the Zollverein and Congress of Vienna are both European state-building or state-restoring measures, the two Japanese documents are both about centralization, and the two wars are both diplomatic-military episodes in unification.
Explain why nationalism strengthened Prussia and Piedmont but weakened the Ottoman and Austrian empires. Use at least two specific examples.
Answer: Because nationalism defines the nation as the source of legitimate rule, it helped states whose population was largely one nationality and harmed states ruling many. Prussia could claim to speak for Germans scattered across 39 states, and Bismarck used the Zollverein and three wars to gather them into the 1871 empire; Piedmont under Cavour did the same for Italians, absorbing Lombardy in 1859 and Garibaldi's southern conquests in 1860. The Ottoman Empire, by contrast, ruled Greeks, Serbs, Bulgarians, Romanians, Armenians, and Arabs, and each successful national movement — Greek independence by 1830, Serbian and then Romanian and Bulgarian statehood by 1878 — subtracted territory. The Habsburgs faced the same problem and could only manage it by sharing power with one group in the Ausgleich of 1867, which left Czechs and South Slavs resentful.
The strongest answers do not just list events; they state the underlying rule first — nation equals state — and then show that the same rule adds territory to a national core and subtracts it from a dynastic empire. Naming specific dates and treaties, rather than saying only that empires 'fell apart,' is what makes the argument convincing.
In what sense was the Meiji Restoration a nationalist movement even though it began with a slogan about restoring an ancient emperor?
Answer: The samurai reformers used the emperor as a unifying national symbol to replace loyalty to individual domains and the shogun, then built the institutions of a modern nation-state: prefectures replacing domains in 1871, universal male conscription in 1873, a national school system teaching standard Japanese, and the 1889 constitution.
The language of restoration was backward-looking, but the content was transformative. Nationalism everywhere borrowed old symbols — medieval heroes in Germany, Roman glory in Italy — to justify new centralized states. Recognizing that a traditional symbol can serve a modern purpose keeps students from reading Meiji Japan as simple conservatism or as pure Western imitation; it was defensive modernization aimed at ending the unequal treaties and preserving independence.
FAQ
- What is the difference between nationalism and patriotism?
- Patriotism is affection or loyalty toward the country you live in. Nationalism is a political doctrine claiming that a nation — defined by shared language, culture, and history — ought to have its own sovereign state. That doctrine is why nationalism redrew maps: it says existing borders are illegitimate if they split a nation or trap several nations together.
- Why did the Revolutions of 1848 fail almost everywhere?
- The revolutionaries were split. Liberals wanted constitutions, nationalists wanted new borders, and workers wanted economic relief, and these goals often clashed — in the Habsburg lands, for instance, Hungarian nationalists faced Croat and Romanian nationalists who resisted Hungarian rule. Meanwhile the monarchs still controlled the armies. The failure convinced Cavour and Bismarck that unification required state power and diplomacy rather than assemblies.
- Was Italian unification really complete in 1861?
- No. The Kingdom of Italy declared in 1861 still lacked Venetia, which came in 1866 as a reward for siding with Prussia against Austria, and Rome, taken in 1870 when French troops protecting the Pope withdrew for the Franco-Prussian War. Even afterward, deep economic and cultural gaps between north and south, plus the papacy's refusal to recognize the state, meant political unity ran ahead of national feeling.
- How does this topic connect to the New Imperialism lesson that follows?
- Unified Germany, Italy, and a centralized Japan were new great powers that arrived after Britain and France had already claimed much of the world, and each used overseas empire to prove national strength. National rivalry also raised the stakes of colonial competition, and the collapse of Ottoman authority in the Balkans and North Africa opened territory those powers rushed to claim.
