Unification of Italy and Germany: Nationalism in Europe
World history notes on nationalism in Europe and the unification of Italy and Germany: Mazzini, Cavour, Garibaldi, Bismarck, the wars and the key dates.
By GK24 Editorial Team· Published · 5 min read

In 1815 neither Italy nor Germany existed as a country. Italy was broken into seven states and Germany into a loose confederation of thirty-nine; both were, in the famous phrase of the Austrian chancellor Metternich, only a geographical expression. By 1871 both were single kingdoms with a capital, a parliament and an army. How that happened is the one chapter of world history that SSC, Railway, State and UPSC papers ask every year, and it is asked as names and dates: who was the soul, the brain and the sword of Italian unity, which three wars Bismarck fought, and where the German Empire was proclaimed.
How nationalism spread in Europe
The idea that people who share a language, a history and a culture should govern themselves came out of the French Revolution of 1789. The revolutionaries replaced the subject with the citizen, gave France a tricolour, an assembly and a uniform system of weights and measures, and carried these ideas across Europe with Napoleon's armies. Napoleon's Civil Code of 1804, usually called the Napoleonic Code, abolished privileges based on birth and secured the right to property, and it survived him in the lands he had conquered. After his defeat the Congress of Vienna of 1815, dominated by Metternich, restored the old monarchies and set up a German Confederation of thirty-nine states to keep the balance of power. Conservatism could not hold: Greece won independence from the Ottoman Empire in a war from 1821, recognised by the Treaty of Constantinople in 1832, and revolutions broke out across Europe in 1830 and again in 1848. Artists gave the new nations female figures, Marianne for France and Germania wearing a crown of oak leaves for Germany, and the French artist Frederic Sorrieu painted his four prints of a world of democratic republics in 1848.
The unification of Italy, 1831 to 1871
Of the Italian states only Sardinia-Piedmont was ruled by an Italian princely house. The north was held by Austria, the centre by the Pope and the south by the Bourbon Kingdom of the Two Sicilies. Secret societies called the Carbonari began the struggle; Giuseppe Mazzini, exiled from Italy, founded Young Italy at Marseilles in 1831 and Young Europe at Berne in 1834, and preached a unitary Italian republic. The practical work fell to Count Camillo di Cavour, chief minister of Sardinia-Piedmont, who was neither a revolutionary nor a democrat but a shrewd diplomat. At Plombieres in July 1858 he secured the help of Napoleon III of France, and the war of 1859 took Lombardy from Austria, Nice and Savoy going to France in payment. In May 1860 Giuseppe Garibaldi sailed from Genoa with about a thousand volunteers in red shirts, took Sicily and then Naples in his Expedition of the Thousand, and handed the south over to the king instead of keeping it. On 17 March 1861 Victor Emmanuel II of Sardinia-Piedmont was proclaimed King of Italy. Venetia followed in 1866, after Austria's defeat by Prussia, and Rome in 1870, when French troops left the city during the Franco-Prussian War; Rome became the capital in 1871.
| Who | Title given to him | What he did |
|---|---|---|
| Giuseppe Mazzini | Soul or prophet of unification | Young Italy, 1831; wanted a republic |
| Count Cavour | Brain or architect | Diplomacy, the French alliance, the war of 1859 |
| Giuseppe Garibaldi | Sword of unification | Red Shirts; Sicily and Naples, 1860 |
| Victor Emmanuel II | First king of united Italy | Crowned 17 March 1861 |
The unification of Germany under Prussia
Germany's first attempt at unity was made by its middle class. The Zollverein, a customs union formed in 1834 under Prussian leadership, abolished tariff barriers between most German states and built one economic space before the political one. In May 1848 an elected Frankfurt Parliament met in the Church of St Paul, drafted a constitution for a German nation under a monarch answerable to a parliament, and offered the crown to Friedrich Wilhelm IV of Prussia; he refused it and the assembly was dissolved. Unity then came from above. Otto von Bismarck became Minister-President of Prussia in 1862 and declared that the question would be settled not by speeches but by blood and iron. He fought three short wars, each gaining territory and each isolating the next enemy: against Denmark in 1864 over Schleswig and Holstein, against Austria in 1866, decided at the Battle of Sadowa, also called Koniggratz, and ended by the Treaty of Prague, and against France from 1870, decided at Sedan where Napoleon III was taken prisoner. On 18 January 1871 Wilhelm I of Prussia was proclaimed German Emperor in the Hall of Mirrors at Versailles, and the Treaty of Frankfurt gave Germany Alsace and Lorraine. Prussian currency, banking, law and judicial practice were then extended over the new empire.

Why the two stories are compared
Both nations were made in the same decade and both were built around one strong state, Sardinia-Piedmont in Italy and Prussia in Germany, which supplied the army, the king and the minister. Both used war with Austria as the lever, and both finished at the expense of France. The difference is the part played by popular movements: Italy had Mazzini's republicans and Garibaldi's volunteers, while Germany's unity was the work of a conservative chancellor who deliberately kept liberals out of it. Examiners test that contrast in statement questions, and test the rest as single facts.
Exam Point of View
Questions are single facts: who founded Young Italy and where, which leader is called the sword or the brain of Italian unity, the year of the Zollverein, the three wars of Bismarck and their order, the battle that decided the Austro-Prussian War, and the hall in which the German Empire was proclaimed. The standard traps are 1861 against 1871, Mazzini against Cavour as the maker of the kingdom, Sadowa against Sedan, and the belief that Garibaldi made himself ruler of the south when he actually handed it to Victor Emmanuel II. UPSC prefers statement questions comparing the Italian and German paths, and SSC and Railway papers keep to one name or one year.

Read the full explanation →Frequently Asked Questions
Who is called the sword of Italian unification?
Giuseppe Garibaldi. He raised the volunteer Red Shirts, sailed from Genoa in May 1860 with about a thousand men, conquered Sicily and Naples, and then handed the south to Victor Emmanuel II instead of ruling it himself. Mazzini is called the soul or prophet of unification and Cavour the brain or architect.
When and where was the German Empire proclaimed?
On 18 January 1871, in the Hall of Mirrors of the palace of Versailles in France, where Wilhelm I of Prussia was declared German Emperor while the Franco-Prussian War was ending. The place is deliberately chosen in questions because it was French soil.
What was the Zollverein?
A customs union of German states formed in 1834 under Prussian leadership. It abolished tariff barriers and reduced the many currencies in use, creating a single economic zone that prepared the way for political unification three decades later.
Which three wars did Bismarck fight to unite Germany?
The war against Denmark in 1864 over Schleswig and Holstein, the war against Austria in 1866 decided at the Battle of Sadowa, and the war against France in 1870-71 decided at Sedan. Each war isolated the next enemy and ended with Prussia stronger.
Why is 1861 important for Italy but 1871 for Germany?
The Kingdom of Italy was proclaimed on 17 March 1861 under Victor Emmanuel II, though Venetia came only in 1866 and Rome in 1870, becoming the capital in 1871. The German Empire was proclaimed on 18 January 1871. So 1861 is the birth of Italy and 1871 the birth of Germany.
Who refused the crown offered by the Frankfurt Parliament?
Friedrich Wilhelm IV, the King of Prussia, refused the crown offered by the elected Frankfurt Parliament in 1848 because it came from a popular assembly and not from the princes. The parliament was dissolved and the liberal middle-class attempt at unification failed.
