🇮🇹 How was Italy Unified? (1848–1870)

Hello Historians! This chapter is all about how Italy transformed from a collection of divided, competing states into one single nation. Think of Italy before 1848 like a jigsaw puzzle with the pieces scattered and held down by powerful neighbours. We are going to explore the key people who helped glue those pieces together—the dreamers, the schemers, and the fighters!

This process is called the Risorgimento (which means ‘Resurgence’ or ‘Rebirth’). It shows us how nationalism (the belief that people sharing a common culture should form an independent state) combined with strong leadership and smart politics can change the map of Europe.

Key Terms You Must Know

  • Nationalism: The desire of people with the same history, language, and culture to govern themselves as one nation.
  • Liberalism: Political movement favouring individual rights, constitutional government, and reform.
  • Piedmont-Sardinia: The strongest, most liberal Italian state, ruled by the House of Savoy. It became the base for unification.
  • Realpolitik: Practical politics based on what is necessary and realistic, rather than ideals or morals (Cavour was famous for this).

1. Italy Before Unification: Austrian Influence and the Dreamers

Austrian Control and Division

In the mid-19th century, Italy was not a country. It was divided into several small states. The biggest obstacle to unification was the presence of the Austrian Empire.

  • Austria directly controlled the wealthy northern regions of Lombardy and Venetia.
  • Austria also exerted powerful influence over other central states (like Tuscany).
  • The central region was controlled by the Papal States, ruled by the Pope. The Pope was generally against unification, fearing the loss of his temporal power.
  • The South was the Kingdom of the Two Sicilies, ruled by the Bourbon dynasty (a branch of the Spanish royal family).

Analogy: Austria was like the school bully making sure the smaller Italian kids stayed separated and did what they were told.

The Role of the Dreamer: Mazzini

Long before unification was practical, radical nationalists provided the essential ideas. The most famous was Giuseppe Mazzini (1805–1872).

  • Mazzini believed unification had to come from the people, not the rulers. He was a committed republican (meaning he wanted a state without a king).
  • He founded the secret society Young Italy in 1831, aiming to educate Italians about the need for a single, united Italian Republic.
  • His influence spread the nationalist dream, often called the "soul" of unification.

Quick Review: Mazzini provided the vision, but lacked the military and political power to make it happen.


2. The Failed Revolutions of 1848–1849

Why wasn't Italy unified in 1848–49?

Inspired by widespread revolutions across Europe in 1848, Italians rose up against their rulers and the Austrians. Hopes were high, but the uprisings failed miserably.

Causes, Events, and Results in Italy (1848–49):
  • Causes: Growing nationalist feeling (thanks to Mazzini) combined with Liberal demands for constitutions and freedom.
  • Events: Revolts forced rulers in several states (like Naples and the Papal States) to grant constitutions or flee. Piedmont-Sardinia, led by King Charles Albert, declared war on Austria to seize Lombardy and Venetia.
  • Failure: The revolts were crushed by 1849 because:
    1. Lack of Unity: Different revolutionary groups wanted different things (some wanted republics, others wanted constitutional monarchies).
    2. Austrian Strength: The Austrian army quickly recovered and defeated Piedmont-Sardinia's forces easily (e.g., at Custozza and Novara).
    3. The Pope’s Influence: Pope Pius IX withdrew his support for the revolution, damaging the morale of many Catholic participants.

Key Takeaway: The events of 1848 proved that unification would only succeed under the guidance of a strong, established state (Piedmont) and required external help against Austria.


3. Cavour and the ‘Brains’ of Unification

Victor Emmanuel II and Cavour

After the disaster of 1848, the Kingdom of Piedmont-Sardinia remained the only Italian state with a liberal constitution and a native monarch, Victor Emmanuel II. In 1852, he appointed Count Camillo di Cavour as Prime Minister.

Cavour was the master politician of unification. He was not a romantic dreamer like Mazzini; he focused purely on strengthening Piedmont and using diplomacy and war to achieve his goals (Realpolitik).

Did Cavour help or hinder the unification of Italy?

Cavour definitely helped unification, though initially, his goal was just to expand Piedmont's power, not necessarily unify all of Italy. His methods were crucial:

  1. Modernisation: He reformed Piedmont's economy, building railways and increasing trade, making it the most powerful state.
  2. International Status: He needed powerful friends. He sent Piedmontese troops to help Britain and France in the Crimean War (1854–56). This gave him a seat at the peace conference and introduced the 'Italian Question' to Europe.
  3. The French Deal: The Agreement of Plombières (1858)
    Cavour met secretly with French Emperor Napoleon III. They agreed that France would help Piedmont fight Austria, on the condition that Piedmont gave Nice and Savoy to France. This was the crucial first step to removing Austria.

War with Austria (1859)

Cavour provoked Austria into declaring war. French and Piedmontese forces won key victories at Magenta and Solferino.

  • Unexpected Turn: Suddenly, Napoleon III got cold feet (fearing Prussian intervention and the high casualties) and signed an armistice with Austria at Villafranca without telling Cavour.
  • Austria handed Lombardy to France, who then passed it to Piedmont. Venice remained under Austrian control. Cavour was furious but had to accept it.
  • The Result: Inspired by the war, central Italian states (Tuscany, Parma, Modena) overthrew their Austrian-backed rulers and voted to join Piedmont in 1860.

Memory Aid: Cavour used Cunning and Diplomacy. He got France to fight Austria, leading to Piedmont's expansion.


4. Garibaldi and the ‘Sword’ of Unification

While Cavour was the political architect in the North, the fiercely dedicated revolutionary Giuseppe Garibaldi (1807–1882) brought the South into the new kingdom.

Garibaldi and the Invasion of Sicily and Naples (1860)

This was perhaps the most dramatic stage of unification.

  1. The Expedition of the Thousand: In 1860, Garibaldi, leading about a thousand volunteer soldiers (known as the Red Shirts), sailed from Genoa and landed in Sicily.
  2. Conquest of the South: The Red Shirts rapidly defeated the weak Bourbon army in Sicily and then crossed to the mainland, capturing Naples. Garibaldi was incredibly popular, seen as a great liberator by the peasants.
  3. The Dilemma: Garibaldi planned to march on Rome, but Cavour saw this as dangerous. If Garibaldi attacked Rome, France (who protected the Pope) or Spain might intervene, restarting the war and risking everything Cavour had achieved.
How important was Garibaldi's contribution?

Extremely important! Without Garibaldi's military genius and popularity, the southern half of the peninsula would never have been conquered so quickly.

  • He was the heroic face of the movement, uniting radical republicans behind the cause.
  • He provided the military success that Cavour’s diplomacy lacked in the south.

The Handover (The Meeting at Teano)

To prevent Garibaldi from attacking Rome, Cavour sent Piedmontese troops into the Papal States (avoiding Rome itself). Cavour convinced Garibaldi to sacrifice his republican ideals for the sake of unity.

In October 1860, Garibaldi met Victor Emmanuel II at Teano and handed over control of Sicily and Naples to the King. Garibaldi then famously retired to his farm, refusing honours or payment. This act cemented Victor Emmanuel’s legitimacy as the leader of the entire country.

Quick Review: Cavour and Garibaldi had different methods, but their combined efforts proved unstoppable. Cavour provided the international legitimacy; Garibaldi provided the military victories.


5. The Kingdom of Italy and Final Steps

The Creation of the Kingdom of Italy (1861)

In March 1861, the Kingdom of Italy was officially proclaimed. Victor Emmanuel II was declared King. However, unification was not yet complete. Two major areas were missing:

  1. Venetia (still held by Austria).
  2. Rome (still held by the Pope, protected by French troops).

Completion of Unification by 1870

  • 1866: The Acquisition of Venetia
    Italy allied with Prussia during the Austro-Prussian War (1866). Although the Italian army was defeated by Austria, Prussia decisively won the overall war. As a result, Prussia forced Austria to hand Venetia over to Italy.
  • 1870: The Acquisition of Rome
    The final piece of the puzzle fell into place during the Franco-Prussian War (1870). When France was defeated by Prussia, Napoleon III had to withdraw his protective French troops from Rome to fight in France. Italian forces seized Rome immediately.

Rome officially became the capital of the united Italy in 1871, marking the completion of the Risorgimento.


6. International Importance and Key Takeaways

How important for other European countries were moves towards Italian unification?

Italian unification had significant ripple effects across Europe, particularly because it relied on weakening or distracting major powers:

  • Austria was weakened: Austria lost territory, influence, and military prestige in 1859 and 1866. This shift in the balance of power made it easier for the German states to challenge Austrian dominance later.
  • France was involved (and later distracted): Napoleon III played a dangerous game. His initial support for Italy (Plombières) helped unification, but his later need to withdraw troops from Rome in 1870 directly enabled the completion of unification. The Franco-Prussian War, which allowed Italy to take Rome, was a major turning point in European politics.
  • Paving the way for Germany: Cavour’s success using military alliances (with France in 1859, with Prussia in 1866) provided a clear model for Bismarck’s later strategy in unifying Germany (unification through "blood and iron").

Study Checklist: Key Players and Their Roles

To ace your exam questions on Italian unification, remember the ‘Mind, Cunning, and Greatness’ framework:

  • Mazzini (Mind): The philosophical foundation; the driving idea of Italian nationalism and republicanism.
  • Cavour (Cunning): The pragmatic politician; used diplomacy (Plombières), economy, and foreign wars (1859, 1866) to achieve success for Piedmont.
  • Victor Emmanuel II (Monarchy): Provided the necessary figurehead and the military strength of Piedmont.
  • Garibaldi (Greatness): The heroic military force; conquered the South (Sicily and Naples) with the Red Shirts in 1860.

Don't worry if all the dates seem tricky at first! Focus on the *sequence* of events: Idea (Mazzini) -> Failure (1848) -> Diplomacy (Cavour) -> War (1859) -> Military Action (Garibaldi 1860) -> Completion (1870).
