Military history of Portugal

The Military history of Portugal is as long as the history of the country, from before the emergence of the independent Portuguese state.

Before Portugal
Before the emergence of Portugal, between the 9th and the 12th centuries, its territory was part of important military conflicts – these were mainly the result of three processes.

Roman Expansion

 * The conflict between Ancient Rome and Carthage for the dominion of the western Mediterranean sea, mainly occurred in Iberia (the Roman Hispania) during the Second Punic War from 218 to 201 BC.
 * The Roman conquest of Hispania, a long process from 218 BC (in the context of the Second Punic War) to 17 BC (already during Emperor Augustus), that had three major confrontations regarding modern Portuguese territory:
 * The Lusitanian War from 155 to 139 BC, between the Romans and the Lusitanians, namely during the period these were led by Viriathus.
 * The expedition and conquest of Gallaecia (north of Portugal and Galicia), from 135 and 132 BC, led by Consul Decimus Junius Brutus Callaicus.
 * The Cantabrian Wars from 29 to 19 BC, in the last stade of Roman conquest, that, although not directed at populations in the present Portuguese territory, greatly involved military movements in what is now the north of Portugal.
 * The Roman republican civil wars that took place, wholly or partially, in Hispania, even if in interaction and connection to the process of conquest, namely:
 * Sertorius' revolt in Hispania, from 83 to 72 BC, under the leadership of Sertorius.
 * Caesar's civil war, from 49 to 45 BC, between Julius Caesar and the optimates (conservative republicans), initially led by Pompey.

Germanic Expansion


The invasions during the Migration Period and the Decline of the Roman Empire, in the beginning of the 5th century, and the subsequent conflicts between conquerors (until the 8th century), namely:
 * Invasion of Roman Gallaecia by the Germanic Suevi (Quadi and Marcomanni) under king Hermerico, accompanied by the Buri in 409.
 * Invasion of Hispania by the Germanic Vandals (Silingi – established in Baetica, and Hasdingi – established in interior Gallaecia, near the Suevi) and the Sarmatian Alans (established in Roman Lusitania), in 409.
 * Invasion of Hispania by the Germanic Visigoths led by King Theodorid, expanding from Aquitaine and under request by the Romans, in 410, establishing the Visigothic Kingdom of Hispania.
 * The war between The Suevi and the Hasdingi Vandals, were the first resisted with Roman aid, in 419.
 * The war between the Alans and the Suevi and Romans, were the last two are defeated at the Battle of Mérida, in 428.
 * The war between the Visigoths and the Vandal-Alanic alliance, that ended in 429, with most of the Vandals and Alans moving to North Africa.
 * The on and off continuous dynastical disputes between the Suevi.
 * The on and off continuous war between the Suevi and the Visigoths, that ended when the Visigothic king, Liuvigild, conquered the Suevic kingdom in 585.
 * The war between the Visigothic Kingdom of Hispania and the Byzantine Empire in its southern Iberian province of Spania, from 552 until 624.
 * The dynastic and civil war in the Visigothic Kingdom between the supporters of Achila II (controlling most of eastern Hispania) and Roderic (controlling most of western Iberia).

Islamic Expansion

 * The Moorish Umayyad conquest of Hispania, from 711 to 718, taking advantage of the civil war, and that established the Islamic Al Andalus.
 * The Reconquista, from 722, initially led by Pelagius of Asturias, until 1249 (in Portugal only), the Christian reaction to the Muslim invasion in which several Christian kingdoms slowly expanded themselves over Iberia at the expense of the Moorish states of Al-Andalus, and in the context of which Portugal emerges as an autonomous entity as the First County of Portugal, in 868, when Count Vímara Peres conquers the area from the Minho River to the Douro River, including the city of Portus Cale, from where the name and political entity of Portugal issued.

Riots of Campo de Ourique and conspiracy of the Marquis of Alorna (1803)
In 24 and 25 July, 1803, in Campo de Ourique, Lisbon, a regiment of infantry commanded by liberal army man Gomes Freire de Andrade and the Legion of Light Troops commanded by the also liberal-leaning Marquis of Alorna motineed against the state authorities, entering in confrontation with the then recently created Royal Guard of the Police. The end of the motinees of forcing political liberalism on Portuguese government didn't succeed.

Conspiracy of Mafra (1805)
In 1805, then Princess regent (soon afterwards Queen) Carlota Joaquina promoted a conspiracy in Mafra with the objective of removing her husband Prince João from regency by claiming him to be metally incapable, assuming regency on her own in his place, being aided in the attempted coup by the Count of Sabugal, the Marquis of Ponte de Lima, the Count of Sarzedas, the Marquis of Alorna and Francisco de Melo. The attempted conspiracy did not succeed, but it did increase the tension between the couple to the point of a divorce or separation being considered, which was never advanced due to the damage that it would bring to the Portuguese state, and the couple still had two children after the attempted conspiracy of Carlota (Maria da Assunção, born in 1805, and Ana de Jesus Maria, born in 1806), although there are suspicions about the possibility of the four children of the couple born after 1801, including the 1802 born Miguel, were not children of João but of one or several of the lovers of Carlota Joaquina).

Riots of Saint Torcato (1805)
The riots of Saint Torcato was a popular uprising in the Portuguese country side with a strong mixture of religious influence and zealotry.

First invasion
During the Napoleonic Wars, Portugal was, for a time, Britain's only ally on the continent. Throughout the war, Portugal maintained a military of about 200–250 thousand troops worldwide. In 1807, after the Portuguese government's refusal to participate in the Continental System, French troops under General Junot invaded Portugal, taking Lisbon. However, a popular revolt against Junot's government broke out in the summer of 1808 and Portuguese irregulars took up arms against the French. This enabled a British army under Arthur Wellesley to be landed in Portugal where, aided by Portuguese troops, defeated Junot at the Battle of Vimeiro; this first French invasion was ended by the Convention of Sintra negotiated by his superiors, which shamefully allowed Junot's men to withdraw unmolested with their plunder. Meanwhile the general revolt against the French in Spain led to the landing of Sir John Moore in the north of that country, forcing Napoleon himself to lead an army into the Peninsula. Though Moore was killed the British managed to extricate themselves from the Peninsula in the Battle of La Coruña. Portugal itself, however, remained independent of the French, and Napoleon left things in the Iberian Peninsula in the hands of Marshal Soult.

The Second and Third invasions
Soult proceeded to invade Portugal in the north. However, the Portuguese held on, giving the British the impetus to send Wellesley back with additional regiments of troops to help recover the Iberian peninsula. Wellesley, aided by the remaining Portuguese regiments hastily scraped together, liberated Portugal. A third invasion took place, led by Marshal Andre Masséna. The Anglo-Portuguese Army managed to halt the French advance at the fortifications of Torres Vedras and successfully defeat Masséna's troops, and slowly recovered the Iberian peninsula. Wellesley was made Duke of Wellington in recognition of his services. The Portuguese army was put under the command of Marshal Beresford and was most heavily engaged under his leadership in the bloody Battle of Albuera. Portuguese forces also formed part of Wellington's advance into southern France, 1813–14.

Persecutions of the Setembrizada (1810)
The Setembrizada was the arrest and deportation of a group of personalities connected to the Portuguese Freemasonry, Jacobinist currents and following of the ideals of the French Revolution who had collaborated with the French occupation during the First Invasion, with the first detentions occurring between 10 and 13 of September, 1810 (hence the name setembrizada), after the entry of the Second Invasion lead by general Nicolas Jean de Dieu Soult. By 1814, King João VI gave an amnisty to all the former collaborationists.

Martinhada (1820)
In 11 November, 1820 (day of St. Martin, hence the name of the revolt, also known in slang as "o imbróglio", "the plot" or "a pavorosa", "the dreadful one"), a group of military leaders known as exaltados (exaulted-ones), who challenged the civilian rule in which the 1820 liberal Provisional Junt of Supreme Government of the Kingdom was falling and also what they considered to be the moderate proposals of a constitutional being drawn under influence of the liberal orator Manuel Fernandes Tomás, defending instead the immediate adoption of the Cádis Constitution or even a more advancedly liberal one. These groups rose up in a paradoxical wide informal coalition with conservative military and politicians and radical bourgeois people. It had a brief success, but by 17 November of the same year a counter-coup restores Manuel Fernandes do leadership of the Junta, forcing some Martinhada leaders, like Gaspar Teixeira de Magalhães e Lacerda, António da Silveira Pinto da Fonseca and Bernardo de Sá Nogueira, forced to exile, and only the sections of the Constitution relating to electoral instructions are adopted, at 22 November, 1820, with the first elections after the 1820 Revolution (the elections for the General Extraordinary and Constituting Courts, that is, the Constitution writing constituting assembly) occurring under those instructions between 10 and 27 December, 1820.

The Vilafrancada (1823)
The Vilafrancada was the first of two uprisings of Prince D. Miguel's uprisings supported by several other people of traditionalist and absolutist leanings, against the liberalism adopted by his father D. João VI in the later phase of his rule.

The Abrilada (1824)
At 30 April, 1824, Prince D. Miguel rose again against his father. The King took refuge abord the British ship Windsor Castle, with aid of the Portuguese diplomatic corp, while grandes of the kingdom like the Duke of Palmela are arrested in Belém, being then moved to imprisonment in Peniche, with the then intendent-general of police Baron of Rendufe being persecuted by the Miguelist rise-up, which then turns its attentions to the Count of Vila Flor (later more famous for its future title of Duke of Terceira) and the Count of Paraty. The reactionary philosopher José Agostinho de Macedo was one of the leaders of the rallying up of support among the masses for the movement, denouncing the prisoners the movement makes at political rallies. At 13 May D. Miguel is finally forced to leave for exile on board of the frigatte Pérola towards France, while in the following day D. João returns to Bemposta, and impeaches the brutal pro-Miguelist Minister of Justice José António de Oliveira Leite de Barros, replacing him by Friar Patrício da Silva, and the Duke of Palmela is risen to Minister of the Kingdom.

The Liberal Wars (1828–1834)
After the Napoleonic War, the British ruled Portugal in the name of the absent king in Brazil, with Beresford as de facto Regent, until the Liberal Revolution of 1820 when they were driven out and the king was forced to return as a constitutional monarch. Over the next 25 years the fledgling Portuguese democracy experienced several military upheavals, especially the Liberal Wars fought between the brothers Dom Pedro, ex-Emperor of Brazil and the absolutist usurper Dom Miguel. To assert the cause of the rightful Queen, his daughter Maria da Glória, Pedro sailed from Terceira in the Azores with an expeditionary force consisting of 60 vessels, 7500 men including the Count of Vila Flor, Alexandre Herculano, Almeida Garrett, Joaquim António de Aguiar, José Travassos Valdez and a volunteer British contingent under the command of Colonels George Lloyd Hodges and Charles Shaw and effected a landing at Mindelo on the shores north of Porto. On 9 July Porto was taken by the liberal forces, and after an inconclusive result at the Battle of Ponte Ferreira on 22–23 July were besieged in the city by the Miguelites for nearly a year until, in July 1833 the Duke of Terceira (as Vila Flor had now been created) was able to land in the Algarve and defeat Miguel's forces at the battle of Almada. Meanwhile Miguel's fleet was comprehensively defeated by Pedro's much smaller squadron, commanded by Charles Napier, in the fourth Battle of Cape St. Vincent. The Miguelites were driven out of Lisbon but returned and attacked the city in force, unsuccessfully. Miguel was finally defeated at the Battle of Asseiceira, 16 May 1834, and capitulated a few days later with the Concession of Evoramonte. He was exiled, though his supporters continued to plot for his return and cause trouble up to the 1850s.

Other Guerrillas
In the period of instability after the end of the Portuguese Civil War, several guerrillas happened between pro-governamental and anti-governamental local groups and between local groups and government forces, both by forces of the defeated Miguelites who kept the guerrillas and between different factions of Portuguese liberals. Among these were included:
 * Guerrilla of Jorge Boto (a Miguelite guerrilla in the Beira Alta region just after the end of the Civil War and also in the last years of given war )
 * Guerrilla of Dom Manuel Martinini (a liberal guerrilla in the last days of the Civil War and first years right after its end lead by a former Spanish Army officer around Marvão, Alentejo
 * Guerrilla of Galamba (a liberal guerrilla in coastal Alentejo lead by António Manuel Soares Galamba, a liberal politician, MP and guerrilla )

 * Guerrilla of Milhundos (a guerrilla lead by Lieutenant Milhundos)
 * Guerrilla of the Marçais
 * Guerrilla of the Garranos (one of the many inner Beiras guerrillas in the 1830s and 1840s right after the Civil War)
 * Guerrilla of the Brandões (the 1834-1869 guerrillas of the Brandão family, first united but soon divided in two branches, the Chartist and the Septemberist one. The most famous leader of the Brandões guerrillas was João Brandão)
 * Several Miguelite guerrillas throughout Portugal besides the Remexido one, lasting some until the Regeneration Coup of 1850

Revolt of Pinotes (1846)
The Revolt of Pinotes was the uprising at Viana do Castelo within the bigger Patuleia revolution.

Montaria (1847)
A failed badly planned attempt of revolt against the government in the afternoon of 29 April, 1847, which ended with the imprisonment of several of the involved members.

Conspiracy of the Hidras (1848)
A conspirative movement in Lisbon and Coimbra in August 1848, inspired by the popular and student's uprising of Paris from 22-24 February, 1848 in Paris (which lead to the fall of king Louis Philippe I and the proclamation of the Republic), it was controlled by the government of the Duke of Saldanha (with detaining of some of the heads of the conspiracy, the remaining ones falling in clandestinity), with the name by which the conspiracy got known derives from the term used by Saldanha to define de organization ("revolutionary hydra)

Colonizing Africa
In the 19th century, Portugal became involved in the scramble for Africa, enlarging its territories in Portuguese Angola, Portuguese Mozambique, Portuguese Cabinda, and Portuguese Guinea.

German incursions in Mozambique
A raid by Paul von Lettow-Vorbeck's remaining troops evaded British troops and managed to penetrate relatively far into Portuguese Mozambique, seizing arms, capturing troops, and sparking unrest among the population (African and European).

Europe
Portugal sent an Expeditionary Corps of two reinforced divisions (40,000 men) to France and Belgium, which fought alongside the British XI Corps. German offensives in the British sector hit the Portuguese hard, with one division destroyed in the Battle of La Lys, April 9, 1918, as it became known in Portugal, or Operation Georgette or the Battle of Estaires to the British. In the Treaty of Versailles, the Portuguese acquired the territory of Kionga from what was once German East Africa.

Involvement in the Spanish Civil War (1936–1939)
Salazar gave material and diplomatic aid to Francisco Franco's nationalist forces while maintaining a formal neutrality. A special volunteer force of 18,000, called Os Viriatos (in honour of Lusitanian leader and Portuguese legendary national hero Viriathus), led by regular army officers was recruited to fight as part of Franco's army, even if unofficially. When the civil war ended in 1939, Portugal and Spain negotiated the Treaty of Friendship and Nonaggression (Iberian Pact). The pact committed the two countries to defend the Iberian Peninsula against any power that attacked either country and helped to ensure Iberian neutrality during World War II.

World War II (1939–1945)
Although Portugal proclaimed neutrality in the conflict, the Japanese Imperial Army invaded the Portuguese Timor colony in distant Oceania, killing thousands of natives and dozens of Portuguese. In response, the Portuguese civilians joined Australia, the Netherlands, the United Kingdom, and the United States against the Japanese. See Battle of Timor.

Portuguese-Indian War (1961)
The Portuguese-Indian War was a conflict with the Republic of India's armed forces that ended Portuguese rule in its Indian enclaves in 1961. The armed action involved defensive action against air, sea and land strikes by a numerically superior Indian force for over 36 hours, and terminated in Portuguese surrender, ending 451 years of Portuguese rule in Goa. Thirty-one Portuguese and thirty-five Indians were killed in the fighting.

Portuguese Colonial War (1961–1974)
Portugal remained steadfastly neutral in World War II, but became involved in counterinsurgency campaigns against scattered guerilla movements in Portuguese Angola, Portuguese Mozambique, and Portuguese Guinea. Except in Portuguese Guinea, where the revolutionary PAIGC quickly conquered most of the country, Portugal was able to easily contain anti-government forces through the imaginative use of light infantry, home defense militia, and air-mobile special operations forces, despite arms embargoes from other European countries. During the counterinsurgency campaigns in Angola and Mozambique, Portugal was significantly aided by intelligence provided by native residents who did not support revolutionary forces. However, a left-wing military coup in Lisbon by Portuguese military officers in 1974 toppled the Caetano government and forced a radical change in government attitudes. Faced with international condemnation of its colonial policies and the increasing cost of administering its colonies, Portugal quickly moved to grant the remainder of its African colonies independence.

International involvement (1991 to present)
Portugal was a founding member of NATO, and, although it had scarce forces, it played a key role in the European approaches. After 1991 Portugal committed several Infantry and Airlanding battalions to international operations. The Portuguese Army keeps soldiers in Bosnia, Kosovo, Macedonia and East Timor (around 6,000 men overall) and it has 128 Guardsmen military police in Iraq (Nasiriyah) under control of the Italian Army. Portugal also sent its soldiers to Afghanistan, which controlled the Kabul airport during 2005. As international observers, Portuguese were also in Croatia, Georgia and Western Sahara.

Portugal has also used its naval forces in recent NATO security operation aimed at combatting piracy in the East African coast. In May 2009 a naval vessel encountered an armed Somali pirate ship and arrested all occupants without any exchange of fire.
