Portugal

• 1. Introduction

  ›

  Portugal sits at the far southwestern edge of Europe, a country where the land simply runs out and the Atlantic takes over. Its borders with Spain have held largely unchanged since the Treaty of Alcanizes in 1297, making them among the oldest established international frontiers anywhere in the world. That longevity raises an immediate question: how does a nation this small, occupying the western tip of the Iberian Peninsula, manage to leave such a large mark on history? Portuguese became the fifth-most widely spoken native language on the planet, with more than 250 million speakers. A sea route to India was opened from here. Brazil was claimed from these shores. The first circumnavigation of the globe was organised by a Portuguese explorer. And yet today Portugal has a population of just over 10.7 million people, projected to fall to 8.3 million by 2100. What shaped this place, and what does it look like now that the empire is long gone?

• 2. Before Portugal Existed

  ›

  Neanderthals roamed the southwestern Iberian peninsula until roughly 37,000 years ago, and a hominin tooth recovered from the Nova da Columbeira Cave in Estremadura places them in the very territory that would one day become Portugal. Homo sapiens arrived around 35,000 years ago and spread quickly across the region. By approximately 5400 BC the Neolithic had begun here, and by the Iron Age, communities in the south were leaving inscribed stele that represent the earliest known evidence of writing on the entire Iberian Peninsula. Pre-Celtic tribes occupied parts of the territory, the Lusitanians held the central inland regions, and Celts inhabited much of the rest. Their presence left traces that run deep, including contributions to the concept of saudade, the distinctly Portuguese disposition toward longing and melancholy that would later find expression in the fado.

  Carthage reached the Mediterranean coast through shared ties with Phoenician-Punic settlements, giving it considerable influence from as early as the 5th or 6th century BC. After Carthage's defeat by Rome in the First Punic War, Hamilcar Barca landed at Gadir in 237 BC, beginning a new Iberian campaign. Rome first invaded the peninsula in 218 BC and expelled the Carthaginians at the Battle of Ilipa in 206 BC. Within two centuries the Roman Republic had annexed nearly the entire peninsula, though it faced fierce resistance from the Lusitanians under their leader Viriathus. When the Western Roman Empire began to collapse in 409, Germanic tribes poured in. Western Iberia became part of the Suebian Kingdom, with Braga as its capital. The Visigoths then defeated the Suebi and ruled until the early 8th century, when, in 711, the Umayyad Caliphate swept in from the south. By 716 most of the peninsula was part of al-Andalus. Vikings also raided the coast, including Lisbon, between the 9th and 11th centuries, and may have established small Norse settlements along the stretch between the Douro and Minho rivers.

  ›

  In 868, Porto was taken from the Moors by Vímara Peres, acting on the orders of King Alfonso III of Asturias. Peres became the first Count of Portugal, a title that marks the first milestone in the country's history as a distinct political entity. The county had a turbulent early existence; it was abolished after the Battle of Pedroso in 1071, then refounded in 1096 when Alfonso VI of León granted it to Henry of Burgundy, who married Alfonso's illegitimate daughter, Teresa of León.

  Henry died in 1112, setting off a power struggle that was resolved decisively at the Battle of São Mamede in 1128. There, Afonso Henriques defeated the forces of his own mother, Countess Teresa, and her ally Fernão Peres de Trava, establishing himself as the sole ruler of the county. He pressed the fight against Muslim-held territory, and in 1139, after winning the Battle of Ourique, he took the title of King. Recognition came from King Alfonso VII of León in 1143 and from Pope Alexander III in 1179 through the papal bull Manifestis Probatum. With north-European crusaders and Christian military orders at his side, Afonso and his successors drove southward until the capture of the Algarve was completed in 1249. An alliance with England, first formed in 1373 during the reign of King Ferdinand I and later strengthened by the Treaty of Windsor, would become the oldest standing alliance in the world. The Black Death struck between 1348 and 1349, devastating the country alongside the rest of Europe. Yet the borders that emerged from this era have proved remarkably durable.

• 4. The Age of Discovery

  ›

  Portugal acquired its first overseas territory when it conquered Ceuta in 1415. That conquest opened a period of systematic global exploration carried out under the sponsorship of Prince Henry the Navigator. Throughout the 15th and 16th centuries, Portuguese sailors moved steadily down the African coast, establishing trading posts dealing in commodities from gold to enslaved people. The Treaty of Tordesillas, signed in 1494, divided newly located lands outside Europe between Portugal and Spain along a line west of Cape Verde.

  In 1498, Vasco da Gama reached India, securing a direct sea route that upended existing trade structures. In 1500, Gaspar Corte-Real sighted Greenland, which had been charted by João Fernandes Lavrador two years earlier; that same year, Pedro Álvares Cabral landed in Brazil and claimed it for Portugal. Portuguese navigators went on to establish trade routes through much of southern Asia and sent the first direct European maritime trade and diplomatic missions to both China and Japan. Ferdinand Magellan, a Portuguese explorer organising a Spanish expedition, completed the first circumnavigation of the globe between 1519 and 1522. The Treaty of Zaragoza, signed in 1529, then divided the Pacific Ocean between the two powers. It was an era of extraordinary reach for a small kingdom on the western edge of the continent, one that would set the terms for the global spread of the Portuguese language and culture.

• 5. Empire, Union, and Decline

  ›

  The death of King Sebastian in battle in 1578, followed by the death of his great-uncle King Henry in 1580, left Portugal without a direct heir to the throne. Philip II of Spain, whose mother Isabella of Portugal was a Portuguese princess, claimed the crown and was confirmed as king of Portugal in 1580. The resulting personal union of the two kingdoms stripped Portugal of an independent foreign policy, pulled it into the Eighty Years' War, and exposed its Indian Ocean trade to sustained Dutch attack. The Dutch-Portuguese War ran from 1595 to 1663 and accelerated the erosion of Portugal's monopoly in that region.

  On the 15th of December 1640, John, Duke of Braganza, was proclaimed king following an uprising of disgruntled nobles, ending the Iberian Union under the Habsburgs and beginning the rule of the House of Braganza. During the reign of John V, large flows of Brazilian gold into the royal treasury through the royal fifth created a resource curse. Industry weakened, cereal production fell, and a gold rush drew population from Portugal to Brazil, ultimately contributing to prolonged economic stagnation. After the gold ran dry, the Marquis of Pombal became de facto ruler following the 1755 Lisbon earthquake. His industrialisation efforts failed, his education policies weakened human-capital formation, and his expulsion of the Jesuits reduced student numbers and contributed to a decline in literacy. When Napoleon demanded Portugal join his Continental System in 1807 and Portugal refused, the French general Junot led an invasion and captured Lisbon. The Portuguese royal family moved the court to Rio de Janeiro, where it remained until 1821. British intervention in the Peninsular War eventually expelled all French troops by 1812, but the damage to Portugal's long-run institutional and economic trajectory was lasting.

• 6. Republic, Dictatorship, Revolution

  ›

  King Carlos I and his son and heir, Luís Filipe, Prince Royal, were assassinated by republican sympathisers in 1908. Two years later, in 1910, the monarchy fell and a republic was declared. Portugal fought on the Allied side during World War I, but the conflict deepened political instability and economic hardship. The First Republic was overthrown in 1926 and replaced by the Ditadura Nacional, which evolved into the right-wing Estado Novo under António de Oliveira Salazar in 1933.

  Portugal remained neutral in World War II under the Estado Novo. In the postwar decades, the growth of African independence movements challenged Portuguese colonial rule, and a prolonged Portuguese Colonial War ran from 1961 to 1974. The Estado Novo fell on the 25th of April 1974, in a military coup known as the Carnation Revolution. The transition to democracy also ended the empire, from the independence of the African colonies to the handover of Macau in 1999. A turbulent period of provisional governments followed, marked by social and political tension, until a failed coup on the 25th of November 1975 cleared the way for a new Constitution and fresh elections. In 1986, Portugal joined the European Economic Community, triggering considerable economic growth. The 2010-2014 financial crisis brought an international bailout and intense austerity, with social consequences that lasted well beyond the crisis itself.

• 7. Land, Climate, and Nature

  ›

  Portugal's total area is 156,597 km2, but more than two-fifths of that is territorial sea and internal waters. Its exclusive economic zone extends over 1,727,408 km2, the third-largest in the European Union and the twentieth-largest in the world. The highest point is Mount Pico on Pico Island in the Azores, rising to 2,351 metres above sea level. Continental Portugal is 67% forests and 24% agricultural land; over 70% of its mainland territory lies below 400 metres in elevation. The Tagus River, entering from Spain, structures the country's geography: 95% of the areas exceeding 400 metres sit north of the river, while the south, encompassing the Alentejo and Algarve, is dominated by rolling plains with 62% of lands below 200 metres.

  The country sits within the Mediterranean basin, the third most diverse hotspot of flora in the world. Over 22% of its land area falls within the Natura 2000 network. Portugal holds 73% of the freshwater fish species endemic to the Iberian Peninsula, the highest proportion for any region in Europe. The Iberian lynx, wolf, and other mammals that once ranged widely were heavily reduced by hunting and habitat loss in the 19th and 20th centuries, though some species have begun re-expanding their native range. Wildfires are a serious ongoing challenge: between 2014 and 2024, Portugal recorded an annual average of 12,496 fires and 112,455 hectares burned, giving it both the highest average number of wildfires and the greatest average burned area in the European Union. Climate change projections suggest average temperatures could rise by as much as 4 degrees Celsius by 2100 relative to the 1970-2010 baseline, with potential consequences for the country's electricity generation capacity.

  Portuguese is the fifth-most widely spoken first language in the world, with around 250 million native speakers, and is one of 24 official and working languages of the European Union. The country is officially secular, but 80.2% of the Portuguese population aged 15 and over identified as Catholic in the 2021 Census. The national day, the 10th of June, is celebrated as the Dia de Portugal, de Camões e das Comunidades Portuguesas, named jointly for the country, the poet Luís Vaz de Camões, and the Portuguese diaspora.

  Portugal ranked sixth in the world in seafood consumption per capita, with each person consuming on average 54 kg of fish in 2023. The country's literary tradition predates the Portuguese language itself, reaching back to the early 13th century with the cantigas, songs drawing practitioners from King Denis I to the minstrel Martin Codax. The earliest known work is the Ora faz ost'o senhor de Navarra, a cantiga de escárnio e maldizer written in Galician-Portuguese by João Soares de Paiva around the year 1200. Portugal has one Nobel Prize-winning author, José Saramago, who received the prize in 1998. In sport, the men's national football team won the UEFA European Championship in 2016 and the UEFA Nations League in 2019 and 2025. In 2001, Portugal became the first country in the world to decriminalize the personal possession and consumption of all drugs, a policy rooted in a tradition of humanistic criminal justice that abolished capital punishment and life imprisonment as far back as the 19th century.
