The Unification of Italy: From Fragmented States to a Nation

How Italy Became a Unified Country

Italy unified on March 17, 1861, when the Kingdom of Italy was proclaimed under Victor Emmanuel II. This process, the Risorgimento ("Resurgence"), was a decades-long fusion of nationalist ideology, revolutionary action, diplomatic maneuvering, and war.

1. Pre-Unification Fragmentation

Post-Napoleon (1815), the Congress of Vienna restored a patchwork:

North: Lombardy-Venetia (Austrian Empire).
Center: Papal States (Pope), Tuscany, Modena, Parma (Austrian-influenced duchies).
South: Kingdom of the Two Sicilies (Bourbon dynasty) — Naples + Sicily.
Piedmont-Sardinia: Only independent Italian state (House of Savoy), the engine of unification.

2. Ideological Foundations

Giuseppe Mazzini: Prophet of republican nationalism. Founded Young Italy (1831). Vision: democratic republic of free citizens.
Vincenzo Gioberti: Neo-Guelph idea: federation under the Pope.
Cesare Balbo / Massimo d'Azeglio: Moderate monarchist: unification under Piedmont-Sardinia.

3. The 1848 Revolutions: The First War of Independence

Uprisings across Europe. In Italy: Milan (Five Days), Venice (Republic), Rome (Republic), Palermo. Piedmont's Charles Albert declared war on Austria. Defeat at Custoza & Novara (1849); Charles Albert abdicated. His son Victor Emmanuel II succeeded. Lesson: Italy couldn't expel Austria alone.

4. Cavour's Realpolitik (1852–1861)

Count Camillo Benso di Cavour, PM of Piedmont-Sardinia, pursued pragmatic diplomacy:

Modernized economy, army, railroads.
Crimean War (1855): Sent troops to ally with France/Britain → seat at Congress of Paris; put "Italian Question" on European agenda.
Plombières Agreement (1858): Secret deal with Napoleon III: France helps Piedmont expel Austria from Lombardy-Venetia; France gets Nice & Savoy.

5. Second War of Independence (1859)

Piedmont + France vs. Austria. Victories at Magenta & Solferino. Austria ceded Lombardy. Piedmont annexed Tuscany, Parma, Modena, Romagna via plebiscites. France took Nice/Savoy (per treaty). Venetia remained Austrian.

6. Garibaldi's Expedition of the Thousand (1860)

Giuseppe Garibaldi, revolutionary, landed in Sicily with 1,000 volunteers ("Redshirts"). Conquered Sicily, crossed to mainland, took Naples. Bourbon Kingdom of the Two Sicilies collapsed. Garibaldi handed over conquests to Victor Emmanuel.

7. Proclamation of the Kingdom (1861)

First Italian Parliament met in Turin (March 1861). Declared Victor Emmanuel II King of Italy. Cavour died June 1861.

8. Completing the Map (1866 & 1870)

Third War of Independence (1866): Allied with Prussia vs. Austria → gained Venetia.
Capture of Rome (1870): French garrison withdrawn (Franco-Prussian War). Italian troops entered Rome (Breccia di Porta Pia). Rome became capital (1871).
