Revolutions of 1820

The Revolutions of 1820 were a wave of liberal and nationalist uprisings across southern Europe and the Mediterranean that linked events in Naples, Piedmont, Portugal, Spain, and Greece with wider currents from the French Revolution and the Congress of Vienna. Sparked by military mutinies, economic distress, and intellectual currents from the Enlightenment and the Napoleonic Wars, the 1820 disturbances combined demands for charters, constitutions, and national autonomy while encountering conservative reaction from the Holy Alliance and the Concert of Europe.

Background and Causes

Economic hardship after the Napoleonic Wars and the return of restored monarchies under the terms ratified at the Congress of Vienna set the stage for revolt, while veterans of the Peninsular War, Greek War of Independence precursors, and officers shaped military politics in Lisbon, Barcelona, Naples (Kingdom of the Two Sicilies), and Turkish-occupied Morea. Intellectual influences from the French Revolution of 1789, the American Revolution, and the writings of Jean-Jacques Rousseau, Montesquieu, and Benjamin Constant circulated among societies such as the Carbonari, the Freemasons, and the Sociedad Patriotica in Portugal. The restoration policies of King Ferdinand VII of Spain, King Ferdinand I of the Two Sicilies, King João VI of Portugal, and the conservative diplomacy of Tsar Alexander I of Russia, Klemens von Metternich, and Prince Talleyrand heightened tensions with liberal factions including the Liberal Revolutionaries of 1820, the Naples Carbonari, and proto-nationalist groups in Philippiades and Filiki Eteria.

Chronology of Uprisings

The sequence began with a mutiny in Porto in July 1820 led by officers influenced by the Liberal Revolution milieu, quickly forcing the return of King João VI and adoption of the Constitution of 1822 (Portugal), while parallel actions in Madrid and Catalonia in 1820–1821 produced the short-lived restoration of the Constitution of 1812 promulgated at Cádiz. In Naples, the Carbonari insurrection in July 1820 compelled Ferdinand I of the Two Sicilies to accept a constitution, until intervention by the Congress of Laibach and Austria in 1821 led by Franz I of Austria and Field Marshal Johann Frimont suppressed the revolt. In Piedmont, the Sardinian uprising of 1821 aimed at imposing constitutional limits on Victor Emmanuel I, but was quelled with Austrian aid under directives from Metternich. In the Aegean, operations by Filiki Eteria and clashes such as engagements around Chios and focal events in Morea evolved into the broader Greek War of Independence (1821–1829), drawing volunteers from Lord Byron and diplomats like Ioannis Kapodistrias.

Key Figures and Movements

Military officers such as Infante Miguel of Portugal-aligned conspirators and Portuguese captains worked with civic groups including the Sociedade Patriótica, while in Spain leaders tied to the Cádiz Cortes and figures like Francisco de Saavedra and Evaristo Fernández de San Miguel played roles. In Naples, the Carbonari network included figures like Giacinto La Lumia and Guglielmo Pepe, and Piedmontese conspirators included Santorre di Santarosa and Vittorio Emanuele II sympathizers. Greek nationalist leaders such as Theodoros Kolokotronis, Alexander Ypsilantis of the Filiki Eteria, and political organizers like Rigas Feraios mobilized maritime communities and philhellene supporters including Lord Byron and Edward Codrington. Conservative actors included Klemens von Metternich, Tsar Alexander I, and Charles X of France, while diplomatic mediators involved the Holy Alliance and the British Foreign Office under figures like George Canning.

Government Responses and Suppression

Restored monarchs invoked diplomatic mechanisms established at the Congress of Vienna and the Holy Alliance to justify interventions. Austria dispatched troops under commanders such as Franz von Stadion and Joseph Radetzky von Radetz to restore order in the Kingdom of Naples and Piedmont, while the Russian Empire and Ottoman Empire pursued their interests in Greece with varying degrees of repression and accommodation. In Portugal and Spain, constitutional concessions—like the Constitution of 1822 (Portugal) and the reinstatement of the Spanish Constitution of 1812—temporarily placated liberals until counter-revolutions, exemplified by Miguelist War tensions and the 1823 French intervention in Spain (the Hundred Thousand Sons of Saint Louis), reversed gains. Repressive measures included trials, exile to locations such as Tenerife and Corfu (Island), executions following court-martials, and the use of secret police modeled on institutions in Vienna and Saint Petersburg.

International Reactions and Consequences

The revolts tested the balance within the Concert of Europe and prompted debates in the British Parliament, the French Chamber of Deputies, and among diplomats in Vienna, St. Petersburg, and London. Great Britain under George Canning adopted a cautious stance, opposing interventionist orthodoxy but wary of revolutionary contagion, while France under the restored Bourbons later sanctioned intervention to restore Ferdinand VII in Spain. The uprisings accelerated the consolidation of nationalist projects that culminated in later conflicts such as the Greek War of Independence, the Liberal Wars (Portugal), and subsequent revolutions of 1830 in France and Belgium. The interventions reinforced Metternichian principles but also exposed the limitations of sustained repression against emerging liberal and nationalist networks like the Carbonari and Filiki Eteria.

Legacy and Historical Significance

Although many immediate constitutional gains were rolled back, the 1820 disturbances crystallized transnational links among liberal, constitutionalist, and nationalist actors—connecting the Iberian Peninsula to the Italian peninsula and the Balkans—and influenced later movements including the Revolutions of 1830, the Risorgimento, and the Greek independence movement. Cultural and intellectual legacies persisted through philhellenic enthusiasm inspired by figures such as Lord Byron and through legal experiments like the Constitution of Cádiz and the Constitution of 1822 (Portugal), which informed later constitutional debates in Spain, Portugal, Italy, and Greece. The events highlighted tensions between conservative diplomacy led by Metternich and emancipatory currents traceable to the Enlightenment, shaping 19th-century European politics and the eventual emergence of nation-states across southern Europe.
