(a) Describe the main revolutionary events in Italy in 1848. [4 marks]

• Revolution began in Sicily in January 1848 against the Bourbon King Ferdinand II of the Two Sicilies. The Sicilians demanded a separate constitution, and the revolt quickly spread to Naples.
• In March 1848, revolts erupted in Milan (the 'Five Days of Milan', 18-22 March, which drove Austrian Field Marshal Radetzky's forces from the city) and Venice (where Daniele Manin proclaimed the Republic of St Mark).
• King Charles Albert of Piedmont-Sardinia declared war on Austria in March 1848, hoping to lead the national movement against Austrian control of Lombardy and Venetia.
• Giuseppe Mazzini established a Roman Republic in February 1849 after Pope Pius IX fled Rome. The republic was defended by Giuseppe Garibaldi against French forces sent to restore papal authority.

(b) Why did Mazzini's Roman Republic of 1849 fail? [6 marks]

• French military intervention: President Louis Napoleon Bonaparte sent French troops to Rome to restore the Pope's temporal authority. French forces besieged Rome from April 1849 and captured the city in July 1849. The republic could not resist a major European power.
• Insufficient military strength: The Roman Republic's defenders, though brave (especially Garibaldi's volunteers), lacked the numbers, equipment and resources to resist a professional European army indefinitely.
• Conservative opposition: Mazzini's republican ideals frightened conservative governments across Europe. No major power was willing to support a republic established at the expense of the Pope, the spiritual leader of Catholic Europe.
• Piedmontese defeat: The republic could not count on support from Piedmont-Sardinia, whose army had already been defeated by Austria at the Battle of Novara in March 1849. Charles Albert abdicated in favour of his son, Victor Emmanuel II.
• Catholic powers united against it: The overthrow of the Pope's temporal power was unacceptable to the Catholic powers of Europe (France, Austria, Spain). Restoring the Pope became a point of principle for conservative Catholicism.
• Internal divisions: The republican movement was divided between radicals and moderates, and between those who wanted social revolution and those who sought only political change. Mazzini's vision of an Italian republic frightened many who might otherwise have supported national unity.

(c) How far did the 1848 revolutions contribute to the eventual unification of Italy? [10 marks]

Arguments that the revolutions made an important contribution:

• Need for foreign support: The revolutions demonstrated that the Italian states could not defeat Austria alone. This lesson was applied by Count Cavour, who allied Piedmont with France in 1858 (the Pact of Plombieres) and used French military support to defeat Austria in 1859.
• Discrediting of republicanism: The failure of Mazzini's republican approach discredited revolution as a method of unification and shifted support towards Piedmont-Sardinia's monarchical leadership. This made Cavour's diplomatic approach more acceptable.
• Piedmont as champion: Charles Albert's willingness to fight Austria in 1848, even though he was defeated, established Piedmont-Sardinia as the champion of Italian nationalism. Under his son Victor Emmanuel II and Cavour, Piedmont became the nucleus of a unified Italy.
• Garibaldi as national hero: Garibaldi's heroic defence of the Roman Republic made him a national hero, inspiring Italians across the peninsula. His later expedition of the Thousand (1860), which conquered Sicily and Naples, was crucial to unification.
• Exposing weaknesses of old order: The revolutions revealed that the Italian states under Austrian domination and reactionary local rulers could not deliver stability or prosperity. This strengthened the case for change.

Arguments that the direct contribution was limited:

• All gains reversed: All the revolutionary gains of 1848-49 were reversed by 1849. Austria restored its control over Lombardy and Venetia, the old rulers returned to power, and the Roman Republic was destroyed.
• Divisions among revolutionaries: The revolutions revealed deep divisions between republicans (Mazzini), monarchists (Charles Albert), federalists (Gioberti) and radicals (Garibaldi). These divisions weakened the movement.
• Austria remained dominant: Austrian military power remained the primary obstacle to unification, and it was not weakened by the events of 1848. Radetzky's victories at Custoza (1848) and Novara (1849) confirmed Austrian supremacy.
• Practical unification through diplomacy: The actual unification of Italy (1859-70) was achieved primarily through Cavour's diplomacy, French military intervention, Garibaldi's military campaigns, and Prussian victory over Austria in 1866, rather than through the legacy of 1848.

Conclusion: The 1848 revolutions were a necessary failure that taught Italian nationalists essential lessons for future success. They demonstrated the need for foreign allies, discredited the republican approach in favour of Piedmontese leadership, created national heroes like Garibaldi, and kept the flame of nationalism alive. While their direct achievements were entirely reversed, the experience of 1848 shaped the strategy and leadership that would successfully unify Italy in the following decade. The revolutions were not the cause of unification, but they were an indispensable stage in the process that made it possible.
