French occupation of Spain The French occupation of Spain (1808–1814) was the period in which forces of the First French Empire intervened in the Kingdom of Spain and installed Joseph Bonaparte on the Spanish throne, triggering widespread resistance and a prolonged military campaign that became a major theater of the Peninsular War. The episode reshaped Iberian politics, provoked transnational alliances involving the United Kingdom, and influenced later independence movements in Spanish America.

Background and causes

Napoleon's intervention grew from dynastic and strategic maneuvering after the abdications at the Bayonne meeting following the War of the Fourth Coalition and the abdication of Charles IV of Spain and Ferdinand VII of Spain. French ambitions were linked to securing lines for the Continental System against the United Kingdom and consolidating influence over the Iberian Peninsula after Franco-Spanish cooperation in the Battle of Austerlitz and treaties such as the Treaty of Tilsit. Internal Spanish crisis involving the Manuel Godoy government, the popular uprisings in Aranjuez and the Mutiny of Aranjuez, and rivalries among the House of Bourbon provided the pretext for military occupation and dynastic replacement.

Invasion and military campaign (1808–1814)

French troops entered Spain under the pretext of reinforcing garrisons; confrontations escalated with the Dos de Mayo Uprising in Madrid and the Battle of Bailén, an early Spanish victory over General Pierre Dupont de l'Étang. Napoleon responded directly, leading the Grande Armée into the peninsula and winning decisive actions such as the Battle of Somosierra and the Battle of Burgos before installing Joseph Bonaparte in Madrid. The campaign fragmented into major operations: Marshal André Masséna's invasion of Portugal, Marshal Jean-de-Dieu Soult's campaigns in Andalusia, Marshal Michel Ney's sieges, and the protracted engagements culminating in the Battle of Talavera and the Siege of Cádiz. British forces under Arthur Wellesley, 1st Duke of Wellington conducted amphibious expeditions, fought actions including the Battle of Vitoria and the Battle of Salamanca, and coordinated with Spanish armies and Portuguese allies to drive French forces northward.

Administration and government under French rule

After Joseph's installation, French administrators attempted centralizing reforms inspired by the Napoleonic Code and rationalizing taxation along lines practiced in the First French Empire. Reforms sought to curtail ecclesiastical privileges associated with the Spanish Church and to modernize municipal institutions in Madrid and provincial capitals, provoking resistance among traditional elites such as the Cortes-oriented oligarchies and Spanish nobility. French authorities created provisional juntas and relied on French military governors, collaborating officials like Baltasar Hidalgo de Cisneros in some locales, and new legal frameworks that clashed with constitutions such as the later Spanish Constitution of 1812 promulgated at Cádiz.

Resistance, guerrilla warfare, and popular reaction

The occupation spawned widespread popular insurgency: a decentralized network of provincial juntas coordinated resistance, while irregular fighters—termed guerrilleros—conducted ambushes, sabotage, and intelligence operations against French convoys and garrisons. Key urban resistances included the sieges of Zaragoza and the defense of Badajoz, and cultural responses were epitomized by Francisco de Goya's wartime prints and scenes. Collaborationist governments, royalist loyalists, liberal proponents, and clerical authorities competed for legitimacy, while leaders like Joaquín Blake and The Duke of Infantado organized conventional armies that fought alongside Wellington's Anglo-Portuguese forces.

International context and diplomatic consequences

The Iberian conflict heightened antagonism between the First French Empire and the United Kingdom, drawing in the Kingdom of Portugal and altering alliances across Europe. The diversion of French resources to the peninsula weakened Napoleon's position in the Russian campaign and the broader War of the Sixth Coalition, while the conduct of the war influenced diplomatic practice exemplified by conferences such as the Congress of Vienna's later deliberations. The occupation and the promulgation of the Spanish Constitution of 1812 also reverberated through Spanish America, accelerating independence movements in viceroyalties like New Spain and Viceroyalty of the Río de la Plata.

Withdrawal, restoration of the Bourbon monarchy, and aftermath

From 1812 onward, successive defeats at the Battle of Salamanca and the Battle of Vitoria and the loss of lines of communication compelled French withdrawal. Wellington's advance, allied Spanish operations, and the collapse of Marshal Jean-de-Dieu Soult's defenses culminated in the French evacuation and the restoration of Ferdinand VII of Spain after the Treaty of Paris (1814). The restoration reasserted the House of Bourbon but left Spain politically fractured, with tensions between absolutists and liberal supporters of the Cádiz constitution; the peninsular experience influenced 19th-century Spanish politics, colonial disintegration, military reform, and conservative-liberal conflicts that continued through the Carlist Wars.
