Through Napoleon and War of independence

The war can be said to have started when the French and Spanish armies invaded and occupied Portugal in 1807 by transiting through Spain, but it escalated in 1808 after Napoleonic France occupied Spain, which had been its ally. Napoleon Bonaparte forced the abdications of Ferdinand VII and his father Charles IV and then installed his brother Joseph Bonaparte on the Spanish throne and promulgated the Bayonne Constitution. Most Spaniards rejected French rule and fought a bloody war to oust them. The war on the peninsula lasted until the Sixth Coalition defeated Napoleon in 1814, and is regarded as one of the first wars of national liberation. It is also significant for the emergence of large-scale guerrilla warfare.

In 1808, the Spanish army in Andalusia defeated the French at the Battle of Bailén, considered the first open-field defeat of the Napoleonic army on a European battlefield. Besieged by 70,000 French troops, a reconstituted national government, the Cortes—in effect a government-in-exile—fortified itself in the secure port of Cádiz in 1810. The British army, under Arthur Wellesley, the future Duke of Wellington, guarded Portugal and campaigned against the French alongside the reformed Portuguese Army and provided whatever supplies they could get to the Spanish, while the Spanish armies and guerrillas tied down vast numbers of Napoleon's troops. In 1812, when Napoleon set out with a massive army on what proved to be a disastrous invasion of Russia, a combined allied army defeated the French at Salamanca and took the capital Madrid. In the following year the Coalition defeated King Joseph Bonaparte's army at the Battle of Vitoria, paving the way for victory in the war in the Iberian Peninsula.

Pursued by the armies of Britain, Spain and Portugal, Marshal Jean-de-Dieu Soult, no longer getting sufficient support from a depleted France, led the exhausted and demoralized French forces in a fighting withdrawal across the Pyrenees during the winter of 1813–1814. The years of fighting in Spain were a heavy burden on France's Imperial Army. While the French won several battles they were eventually defeated, as their communications and supplies were severely tested and their units were frequently isolated, harassed or overwhelmed by Spanish partisans fighting an intense guerrilla war of raids and ambushes. The Spanish armies were repeatedly beaten and driven to the peripheries, but they would regroup and relentlessly hound and demoralize the French troops. This drain on French resources led Napoleon, who had unwittingly provoked a total war, to call the conflict the "Spanish ulcer".

For France, the Peninsular War bogged down Napoleon's troops, which allowed the rest of Europe to challenge Napoleon once more, including in the War of the Fifth Coalition and the French invasion of Russia, and culminating in Napoleon's defeat in the War of the Sixth Coalition. The war against Napoleon's occupation led to the Spanish Constitution of 1812, promulgated by the Cortes of Cádiz, later a cornerstone of European liberalism. Though victorious in war—France would never again threaten a full-scale invasion of Spain—the burden of war destroyed the social and economic fabric of both Portugal and Spain, and the following civil wars between liberal and absolutist factions ushered in revolts in Spanish America that led to the independence of all of Spain's colonies on the American mainland, and the beginning of an era of social turbulence, increased political instability, and economic stagnation in Iberia itself.

1807

Extortion of Portugal

The Treaties of Tilsit, negotiated during a meeting in July 1807 between Emperors Alexander I of Russia and Napoleon, concluded the War of the Fourth Coalition. With Prussia shattered, and the Russian Empire allied with the First French Empire, Napoleon expressed irritation that Portugal was open to trade with Britain. Pretexts were plentiful; Portugal was Britain's oldest ally in Europe, Britain was finding new opportunities for trade with Portugal's colony in Brazil, the Royal Navy used Lisbon's port in its operations against France, and he wanted to deny the British the use of the Portuguese fleet. Furthermore, Prince John of Braganza, regent for his insane mother Queen Maria I, had declined to join the emperor's Continental System against British trade.

Events moved rapidly. The Emperor sent orders on 19 July 1807 to his Foreign Minister, Charles Maurice de Talleyrand-Périgord, to order Portugal to declare war on Britain, close its ports to British ships, detain British subjects on a provisional basis and sequester their goods. After a few days, a large force started concentrating at Bayonne. Meanwhile, the Portuguese government's resolve was stiffening, and shortly afterward Napoleon was once again told that Portugal would not go beyond its original agreements. Napoleon now had all the pretext that he needed, while his force, the First Corps of Observation of the Gironde with divisional general Jean-Andoche Junot in command, was prepared to march on Lisbon. After he received the Portuguese answer, he ordered Junot's corps to cross the frontier into Spain.

While all this was going on, France and Spain signed the secret Treaty of Fontainebleau. The document was drawn up by Napoleon's marshal of the palace Géraud Duroc and Eugenio Izquierdo, an agent for Manuel Godoy. The treaty proposed to carve up Portugal into three entities. Porto and the northern part was to become the Kingdom of Northern Lusitania, under Charles II, Duke of Parma. The southern portion, as the Principality of the Algarves, would fall to Godoy. The rump of the country, centered on Lisbon, was to be administered by the French. According to the Treaty of Fontainebleau, Junot's invasion force was to be supported by 25,500 Spanish troops. On 12 October, Junot's corps began crossing the Bidasoa River into Spain at Irun. Junot was selected because he had served as ambassador to Portugal in 1805. He was known as a good fighter and an active officer, although he had never exercised independent command.

Spanish dilemma

By 1800, Spain was in a state of social unrest. Townsfolk and peasants all over the country, who had been forced to bury family members in new municipal cemeteries rather than churches or other consecrated ground, took back their bodies at night and tried to restore them to their old resting-places. In Madrid, the growing numbers of afrancesados (Francophiles) at court were opposed by the majos: shopkeepers, artisans, tavern keepers, and labourers who dressed in traditional style, and took pleasure in picking fights with petimetres, the young who styled themselves with French fashion and manners.

Spain was an ally of Napoleon's First French Empire; however, defeat in the naval Battle of Trafalgar in October 1805, which had decimated Spain's navy, had removed the reason for alliance with France. Manuel Godoy, the favourite of King Charles IV of Spain, began to seek some form of escape. At the start of the War of the Fourth Coalition, which pitted the Kingdom of Prussia against Napoleon, Godoy issued a proclamation that was obviously aimed at France, even though it did not specify an enemy. After Napoleon's decisive victory at the Battle of Jena–Auerstedt, Godoy quickly withdrew the proclamation. However, it was too late to avert Napoleon's suspicions. Napoleon planned from that moment to deal with his inconstant ally at some future time. In the meantime, the Emperor forced Godoy and Charles IV into providing a division of Spanish troops to serve in northern Europe. The Division of the North spent the winter of 1807–1808 in Swedish Pomerania, Mecklenburg, and towns of the old Hanseatic League and Spanish troops marched into Denmark in early 1808.

Invasion of Portugal

Napoleon instructed Junot, with the cooperation of Spanish military troops, to invade Portugal, moving west from Alcántara along the Tagus valley to Portugal, a distance of only 120 miles (193 km). On 19 November 1807, the French troops under Junot set out for Lisbon and occupied it on 30 November. The Prince Regent John escaped, loading his family, courtiers, state papers and treasure aboard an Anglo-Portuguese fleet, and fled to Brazil. He was joined in flight by many nobles, merchants and others. With 15 warships and more than 20 transports, the fleet weighed anchor on 29 November and set sail for Brazil. The flight had been so chaotic that 14 carts loaded with treasure were left behind on the docks.

As one of Junot's first acts, the property of those who had fled to Brazil was sequestered and a 100-million-franc indemnity imposed. The army formed into a Portuguese Legion, and went to northern Germany to perform garrison duty. Junot did his best to calm the situation by trying to keep his troops under control. While the Portuguese authorities were generally subservient toward their French occupiers, the ordinary Portuguese were angry, and the harsh taxes caused bitter resentment among the population. By January 1808, there were executions of persons who resisted the exactions of the French. The situation was dangerous, but it would need a trigger from outside to transform unrest into revolt.
