Atlantic Southwest Europe (1684–1827 CE): Port Cities, Iberian Shifts, and the Atlantic Grain–Wine Trade

Geography & Environmental Context

Atlantic Southwest Europe encompasses northern Spain (Galicia, Asturias, Cantabria, and León) and central to northern Portugal, including Lisbon. Anchors include the Galician Rías (Ría de Vigo, A Coruña), the Cantabrian Coast, the Minho and Douro valleys, the Tagus estuary at Lisbon, and the rugged mountains of León and northern Portugal. This is a region of Atlantic-facing coasts, fertile river basins, and upland pastures, with maritime corridors tying Iberia to the broader Atlantic world.

Climate & Environmental Shifts

The tail of the Little Ice Age brought heavy rains and cooler winters. Coastal Asturias and Galicia endured storm surges and erratic fishing seasons. In Portugal, alternating droughts and floods affected the Tagus and Douro, stressing vineyards and grain harvests. The Tambora eruption (1815) caused harvest failures and famines in 1816–1817, driving food shortages and migration. Despite shocks, the region remained buffered by mixed farming and Atlantic fisheries.

Subsistence & Settlement

• Agriculture: Grain (rye, maize, wheat) dominated northern Spain’s uplands, while vineyards along the Douro Valley produced the famous port wines increasingly exported to Britain. Olive groves and orchards dotted Portugal’s hills.

• Livestock: Cattle and sheep grazed in León and northern Portugal, supporting cheese and wool exports.

• Fishing & maritime life: Cod and sardines sustained coasts; Galician fisheries supplied local markets.

• Urban centers: Lisbon was the linchpin, linking Brazilian sugar, gold, and coffee to Europe; Porto thrived on the wine trade; A Coruña, Santander, Bilbao grew as shipping points for wool, timber, and iron. Rural hamlets persisted in Galicia’s valleys and Portuguese interior, producing subsistence crops and artisanal goods.

Technology & Material Culture

Stone terraces stabilized vineyards in the Douro; irrigation and watermills supported grain processing in León and Galicia. Shipyards along the Tagus and Douro built ocean-going vessels; Portuguese navigational expertise fed the empire. Urban Lisbon rebuilt in grand style after the 1755 earthquake, with wide boulevards and Pombaline architecture. Material culture blended maritime tools, peasant implements, and luxury imports—Brazilian gold funded churches, palaces, and decorative arts.

Movement & Interaction Corridors

• Transatlantic links: Lisbon was Europe’s primary gateway to Brazil, channeling sugar, gold, diamonds, tobacco, and coffee. The Douro–Porto corridor tied hinterland vineyards to British buyers under the Methuen Treaty (1703), which gave Portuguese wines privileged access to English markets.

• Spanish Atlantic ports: A Coruña, Bilbao, and Santander shipped wool and iron to northern Europe. Galicia supplied emigrants to the Americas.

• Inland trade: Mules carried wine, wool, and grain over mountain passes to port cities.

• War disruptions: During the Peninsular War (1807–1814), French invasions disrupted Portugal and northern Spain, but British naval supremacy kept Lisbon and Porto tied into Atlantic commerce.

Cultural & Symbolic Expressions

• Religion: Catholicism framed life; pilgrimage routes to Santiago de Compostela remained vital. Monasteries in Galicia and León managed estates and provided poor relief.

• Urban culture: Lisbon’s intellectual salons and Porto’s mercantile guilds reflected Enlightenment currents; Coimbra University fostered reformist thinkers.

• Folk traditions: Galician bagpipe (gaita) music, Portuguese fado songs, and rural festivals preserved local identity.

• Architecture: Baroque churches in Braga, Porto, and Santiago embodied both religious devotion and mercantile prosperity.

Environmental Adaptation & Resilience

• Diversification: Maize introduction expanded caloric bases in Galicia and Portugal, reducing famine risk.

• Vineyard specialization: The Douro’s terraced slopes maximized limited arable land, producing high-value exports.

• Fisheries: Cod and sardine fisheries provided fallback protein during poor harvests.

• Charitable networks: Monasteries, confraternities, and parish relief assisted during famines and war dislocation.

Transition

From 1684 to 1827, Atlantic Southwest Europe remained both peripheral and central—a rugged agrarian landscape tied to a global empire through Lisbon and Porto. Portuguese fortunes hinged on Brazil until independence (1822), while Porto’s wine trade locked northern Portugal into Britain’s orbit. Northern Spain’s ports grew modestly, sending wool and emigrants to the Atlantic world, while Galicia remained a land of subsistence peasants and pilgrims. Wars, earthquakes, and famines tested resilience, yet the region adapted through maize, wine, fisheries, and Atlantic trade, foreshadowing new realignments in the 19th century as Iberian empires fragmented and Atlantic economies shifted.

The 1755 Lisbon Earthquake and Pombal’s Radical Reconstruction

On the morning of November 1, 1755, Lisbon was devastated by one of the most destructive earthquakes in European history. The massive tremor, followed by a firestorm and a tidal wave, killed tens of thousands and destroyed most of the city.

The response of Sebastião José de Carvalho e Melo, the Marquis of Pombal, was decisive and transformative, shaping Lisbon’s modern identity and turning it into Europe’s first planned city.

The Disaster: Earthquake, Fire, and Tsunami

• The earthquake, estimated at magnitude 8.5 to 9.0, struck on All Saints' Day, when churches were filled with worshippers.
• Fires ignited by candles and lamps in churches and homes spread uncontrollably, consuming the city.
• A tsunami swept into Lisbon’s harbor and waterfront, destroying ships and drowning thousands.

Pombal’s Immediate Response

Despite the unprecedented scale of destruction, Carvalho, who was in Belém at the time, took swift action. His response demonstrated his effectiveness as a leader:

✔ Emergency Relief Measures

• He improvised hospitals for the injured.
• Controlled prices to prevent profiteering.
• Requisitioned food from the countryside.
• Organized public security, preventing looting and chaos.

✔ Survivor Management and Law Enforcement

• Buried the dead quickly to prevent disease outbreaks.
• Executed looters and criminals publicly, ensuring order.

The Rebuilding of Lisbon: Europe’s First Planned City

After surveying the ruins, Pombal ordered the complete reconstruction of Lisbon, led by:

• Eugénio dos Santos (architect).
• Manuel da Maia (engineer).

Their master plan transformed Lisbon’s city center into a rational, grid-based layout, featuring:

• Long, straight avenues and cross streets for easy navigation.
• Earthquake-resistant buildings, using innovative construction techniques, including wooden frameworks ("gaiola pombalina") designed to absorb seismic shocks.
• Uniform neoclassical architectural styles to give the city a cohesive look.

The rebuilt district, flanked by Praça do Rossio and Praça do Comércio, is known today as the Baixa Pombalina, a symbol of Portugal’s resilience and modernization.

Conclusion: Pombal’s Legacy as a Reformer

Pombal’s bold leadership during the 1755 Lisbon Earthquake demonstrated his Enlightenment ideals and modern governance. His reconstruction of Lisbon set a precedent for urban planning in Europe, while his decisive actions saved lives and restored order. The Baixa Pombalina remains a lasting monument to his vision, ensuring that Lisbon rose from disaster stronger than before.

Pombal’s Educational Reforms: The Foundation of Public Instruction in Portugal

Following the expulsion of the Jesuits in 1759, Sebastião José de Carvalho e Melo, the Marquis of Pombal, undertook sweeping reforms in education, aiming to modernize Portugal’s intellectual infrastructure and establish state-controlled public instruction. He sought to break the Jesuits' hold on education, replacing their scholastic methods with Enlightenment-inspired teaching based on observation and experience.

Key Educational Reforms Under Pombal

✔ Establishing a Public Education System

• Pombal took the first steps toward creating a national public school system, funded by a special tax.
• Schools were set up in major cities, marking a shift from religious to secular education.

✔ Founding of Specialized Schools

• Established Portugal’s first commercial school, focusing on economic and practical training.
• Promoted scientific and technical education, aligning Portugal with contemporary European intellectual trends.

✔ University of Coimbra Reforms

• Blaming the Jesuits for the university’s decline, Pombal reorganized the University of Coimbra to reflect Enlightenment values.
• Created two new departments:
  • Mathematics, to advance scientific knowledge and engineering.
  • Philosophy, emphasizing rationalism and empirical observation.
• Increased the number of professors in existing faculties.

✔ Modernizing Instructional Methods

• Implemented pedagogical changes based on the works of Luís António Verney and António Nunes.
• Shifted from rote learning to observational and experiential learning.

✔ Scientific and Cultural Advancements

• Established Portugal’s first natural history museum.
• Created a botanical garden for scientific research.
• Built an astronomical observatory, advancing astronomical studies in Portugal.
• Developed laboratories, integrating scientific experimentation into education.

Impact of Pombal’s Educational Reforms

✔ Laid the foundation for Portugal’s modern education system.
✔ Weakened the Church’s influence over education, replacing it with state-run schools.
✔ Introduced Enlightenment ideas into Portuguese academia, fostering scientific and economic progress.
✔ Established new research institutions, bridging Portugal with the broader European intellectual movement.

Conclusion: A Modernizer of Portuguese Education

Pombal’s educational reforms marked a decisive shift from Jesuit-dominated instruction to secular, state-controlled learning. By modernizing the University of Coimbra, founding new schools, and emphasizing science and rationalism, he paved the way for Portugal’s intellectual and economic modernization, leaving a lasting impact on the nation’s academic institutions.

Pombal’s Suppression of the Jesuits and His Conflict with the Catholic Church (1759–1760)

After consolidating power, Sebastião José de Carvalho e Melo, the Marquis of Pombal, sought to eliminate the Jesuits, whom he saw as a major obstacle to his Enlightenment-inspired reforms. Accusing them of involvement in the 1758 assassination attempt on King José I, he orchestrated their expulsion from Portugal and its empire in 1759, marking one of the most decisive anti-Jesuit actions in Europe.

The Expulsion of the Jesuits (1759)

• Pombal blamed the Jesuits for plotting against the king, leveraging their influence over the nobility as further justification.
• He searched and confiscated Jesuit properties, shutting down Jesuit-run schools across Portugal and its colonies.
• In 1759, he formally expelled the Society of Jesus from Portugal and all Portuguese overseas territories, including Brazil, India, and Africa.
• The Jesuits were deported to the Papal States, where they were received with suspicion by Pope Clement XIII.

Pombal’s Conflict with the Catholic Church (1760)

Beyond suppressing the Jesuits, Pombal sought to curb the power of the Catholic Church in Portugal, asserting state control over religious affairs:

✔ 1760: Portugal Breaks Relations with the Holy See

• Pombal severed diplomatic ties with the Vatican, challenging papal authority over Portugal’s affairs.
• This move was unprecedented in Catholic Europe at the time.

✔ Arrest of the Bishop of Coimbra

• The Bishop of Coimbra, a vocal opponent of Pombal’s policies, was imprisoned, signaling the state’s dominance over the clergy.

✔ Increased Royal Control Over the Church

• Pombal restricted the Church’s power, placing ecclesiastical affairs under royal oversight.
• He reduced clerical privileges, reinforcing state supremacy over religious institutions.

Consequences of Pombal’s Anti-Jesuit Campaign

✔ Strengthened Royal Absolutism – With the Jesuits and the nobility crushed, Pombal centralized power in the monarchy.
✔ Secularization of Education – Jesuit schools were replaced by state-controlled institutions, advancing secular Enlightenment ideals.
✔ Further Isolation from the Vatican – Portugal’s break with the papacy (1760) marked a radical shift in church-state relations, making Portugal one of the most anti-clerical European states of the era.

Conclusion: Pombal’s Ruthless Modernization

Pombal’s expulsion of the Jesuits (1759) and break with the Holy See (1760) were part of his broader mission to modernize Portugal, reduce clerical influence, and assert state supremacy. His campaign against religious institutions was one of the most extreme in Europe, reshaping Portugal’s political and religious landscape for generations.

Pombal’s Rise to Power and the Purge of the Nobility (1755–1759)

Following his decisive response to the 1755 Lisbon earthquake, Sebastião José de Carvalho e Melo, the Marquis of Pombal, was elevated to chief minister by King José I, consolidating his power as Portugal’s most influential statesman. With a vision of modernizing and centralizing Portugal, Pombal sought to crush any opposition to his reforms, beginning with the aristocracy.

The 1758 Assassination Attempt on King José I

• On September 3, 1758, an assassination attempt was made on King José I, providing Pombal with the justification to move against the nobility.
• The king was injured but survived, and Pombal swiftly blamed the aristocracy.
• He launched a brutal crackdown, using the attack as a pretext to eliminate his noble rivals.

Pombal’s Suppression of the Nobility

• Around 1,000 nobles were arrested, many of whom were accused of participating in a conspiracy against the king.
• Many confessed under brutal torture, and several were executed.
• The most famous victims were:
  • The Távora family, a powerful noble house accused of orchestrating the assassination attempt.
  • The Duke of Aveiro, who was also executed.
  • Other noble families saw their properties confiscated and their power permanently diminished.

Pombal’s Ultimate Goal: Absolute Monarchy and Modernization

• Pombal used the crisis to eliminate aristocratic influence, transforming Portugal into a centralized state under royal authority.
• With the nobility weakened, Pombal accelerated his Enlightenment-inspired reforms, including:
  • Curtailing noble privileges.
  • Expanding the role of the state in economics, administration, and education.

Conclusion: The Fall of the Old Aristocracy

The Távora Affair and the 1758 crackdown on the nobility marked a turning point in Portuguese history, as Pombal reshaped Portugal’s social and political order. By annihilating aristocratic opposition, he secured absolute power for the monarchy and himself, ushering in an era of modernization, but also political repression.

José I (king of Portugal, 1750-77) dies in February 1777, and with him goes Pombal's hold on power and his common sense approach of encouraging industrial development.

Pombal's successor as secretary of state for overseas dominions, Martinho de Melo e Castro, is alarmed that the nascent Brazilian factories could make the colony independent and warns that "Portugal without Brazil is an insignificant power."

In January 1785, he orders that they all be "closed and abolished."

Brazilian students at Coimbra in the early 1780s, had pledged themselves to seek independence.

They are influenced greatly by the success of the North American British colonies in forming the United States of America.

In 1786 and 1787, Jose Joaquim Maia e Barbalho of Rio de Janeiro, a Coimbra graduate studying medicine at Montpelier and a critic of the colonial relationship, approaches Ambassador Thomas Jefferson in France.

He tells Jefferson that the students intend to break with Portugal and requests the aid of the United States.

One of the Coimbra graduates is Jose Bonifacio de Andrada e Silva, the patriarch of Brazilian independence.

The failed Minas Conspiracy (Inconfidencia Mineira) of 1789 involves some of the leading figures of the captaincy: tax collectors, priests, military officers, judges, government officials, and mine owners and landowners.

Some had been born in Portugal, several had had their early education with the Jesuits and later studied at Coimbra, a number write poetry that is still read and studied, but what they have most in common are financial problems caused by crown policies that require them to pay their debts, or that cut them out of lucrative gold and diamond contraband trade.

They argue that Brazil has all it needs to survive and prosper and that Portugal is a parasite.

They pledge to lift restrictions on mining; exploit iron ore; set up factories; create a university, a citizens' militia, and a Parliament; pardon debts to the royal treasury; free slaves born in Brazil; and form a union with São Paulo and Rio de Janeiro similar to that of the United States.

The history of the Minas Conspiracy is full of heavy drama.

Revelation of the conspiracy turns brothers, friends, clients, and patrons against each other in an unseemly scramble to escape punishment.

In one sense, the affair foreshadows the nature of future Brazilian revolutionary movements in that it is a conspiracy of oligarchs seeking their own advantage, while claiming to act for the people.

In the end, Lisbon decides to make an example of only one person, a low-ranked second lieutenant (alferes) of the Royal Mineiro Dragoons named Joaquim Jose da Silva Xavier ("Tiradentes").

His execution in 1792 in Rio de Janeiro might well have been forgotten if the nineteenth-century republicans had not embraced him as a symbolic counterpoise to Dom Pedro I, who declares Brazilian independence from Portugal in 1822.

Later, with the establishment of the republic in 1889, every town and city in Brazil will build a Tiradentes square, and the day of his execution, April 21, will become a well-commemorated national holiday.

Nonetheless, because the Minas Conspiracy is marked more by skulduggery than nobility and clarity, its value as a national symbol requires selective interpretation and presentation.

Portugal resolves to watch Brazilians more carefully and reacts forcefully to a nonexistent but suspected plot in Rio de Janeiro in 1794, and to a real, mulatto-led one in Bahia in 1798.

Meanwhile, the French Revolution, the resulting slave rebellion in Haiti, and the fear of similar revolts in Brazil persuades the Brazilian elites that the dream of a United States-style conservative revolution that will leave the slave-based socioeconomic structure intact and in their hands is impossible.

The crown separates the residents of Minas Gerais from the revived coastal sugar producers through policies that set their interests at odds.

Lisbon diverts Brazilian nationalism with greater imperial involvement.

Atlantic Southwest Europe (1744–1755): Enlightenment Influences, Economic Expansion, and Catastrophic Disaster

Between 1744 and 1755, Atlantic Southwest Europe—including northern and central Portugal (with Lisbon), Galicia, Asturias, Cantabria, northern León and Castile, northern Navarre, northern Rioja, and the Basque Country—witnessed significant economic growth, intellectual vitality influenced by Enlightenment ideals, and increased commercial prosperity driven by maritime trade. However, this flourishing era ended abruptly with the catastrophic Lisbon Earthquake of 1755, profoundly reshaping the region’s political, economic, cultural, and social trajectory.

Political and Military Developments

Portuguese Governance and Enlightenment Reform

• Portugal under King João V (r.1706–1750) and his successor, José I (r.1750–1777), experienced political stability with emerging Enlightenment-inspired reforms. José I's influential minister, Sebastião José de Carvalho e Melo (later Marquis of Pombal), promoted modernization and administrative centralization.

• Northern Portugal, particularly Porto, benefited from improved governance, infrastructural enhancements, and supportive commercial policies.

Regional Stability in Northern Spain

• In Spain under King Ferdinand VI (r.1746–1759), northern provinces—including Galicia, Asturias, Cantabria, and the Basque Country—experienced political stability and economic expansion. Local privileges (fueros) continued to underpin strong regional autonomy, providing robust governance and economic benefits.

• Northern Navarre and the Basque provinces remained politically stable, leveraging local autonomy and economic self-governance to enhance regional prosperity.

Economic Developments: Maritime Prosperity and Trade Growth

Portuguese Maritime Trade Expansion

• Northern and central Portugal’s maritime economy, centered on Lisbon and Porto, prospered with expanded transatlantic trade, particularly to Brazil. Port wine exports from the Douro region surged, bolstering Porto’s economy and enhancing Lisbon’s international stature as a trading hub.

• Shipbuilding and fisheries thrived along Portugal’s Atlantic coast, significantly contributing to urban prosperity and expanding merchant classes.

Basque and Cantabrian Commercial Strength

• The Basque Country, notably Bilbao, emerged as a critical European commercial center, excelling in iron production, shipbuilding, and transatlantic trade.

• Cantabria, particularly Santander, continued to grow economically, leveraging Atlantic trade routes, maritime industry, and fishing to foster regional prosperity.

Religious and Cultural Developments

Enlightenment and Baroque Cultural Fusion

• The Enlightenment influenced cultural institutions, fostering intellectual debates and advancements in education, notably at the University of Coimbra in Portugal and in Spanish institutions such as those in Bilbao and Santander.

• Baroque artistic expression continued to flourish, particularly in architecture, with impressive developments in Lisbon, Porto, Braga, Santiago de Compostela, and Pamplona.

Social and Urban Developments

Urban Expansion and Merchant Class Growth

• Lisbon, Porto, Bilbao, and Santander saw significant urban growth, fueled by maritime commerce and expanding merchant wealth. Urban infrastructure improved markedly, with public works enhancing civic life.

• Regional autonomy under fueros strengthened the social cohesion of communities in northern Spanish provinces, emphasizing distinct cultural and political identities.

The Lisbon Earthquake of 1755: Catastrophe and Consequences

On November 1, 1755, Lisbon experienced a catastrophic earthquake—one of Europe's most devastating natural disasters. The quake destroyed vast portions of Lisbon, followed by destructive fires and a massive tsunami that devastated coastal areas. An estimated 40,000 to 50,000 lives were lost in Lisbon alone, with destruction also affecting coastal communities across Portugal, including Cascais, Setúbal, and regions as far north as Porto and Galicia in northwest Spain.

• Immediate Response and Crisis Management: Minister Sebastião José de Carvalho e Melo swiftly directed emergency responses, organizing relief, controlling disorder, and initiating rapid urban reconstruction. His effective handling greatly increased his political authority, allowing extensive reforms and modernization projects in subsequent years.

• Regional Impact: Porto, while spared catastrophic damage, faced economic disruptions from interrupted trade and damaged maritime infrastructure. Galicia and other northern coastal regions experienced milder effects but endured temporary trade setbacks due to maritime disruptions.

• Cultural and Intellectual Effects: The disaster profoundly impacted European intellectual life, prompting debates about divine providence, philosophical skepticism, and human reason. Enlightenment thinkers such as Voltaire and Kant commented extensively on the earthquake’s moral and philosophical implications.

Legacy and Significance

The period 1744–1755 dramatically transformed Atlantic Southwest Europe. Initially marked by stability, economic expansion, and cultural vitality, the era abruptly ended with the 1755 Lisbon earthquake, reshaping political authority in Portugal and sparking profound intellectual reflections across Europe. The catastrophe accelerated administrative centralization, economic modernization, and urban planning innovations, leaving a lasting imprint on the region’s historical trajectory.

The Great Lisbon Earthquake of 1755 – A Catastrophe Unfolds

On the morning of November 1, 1755, as Portugal observed All Saints' Day, a colossal earthquake struck Lisbon, unleashing one of the most devastating natural disasters in European history. The tremors, estimated at 8.5–9.0 on the moment magnitude scale, shook the city for three and a half to six minutes, creating massive fissures, some as wide as five meters (sixteen feet), in the heart of the Portuguese capital.

The Immediate Chaos

As buildings collapsed, survivors fled to the docks, believing the open space near the Tagus River to be the safest refuge. There, they witnessed a strange phenomenon—the waters receded, exposing a sea floor strewn with shipwrecks and lost cargo, an eerie prelude to the next wave of destruction.

The Tsunami Strikes

Approximately forty minutes after the initial earthquake, a tsunami surged into Lisbon’s harbor, sweeping inland and engulfing the downtown district. The Tagus River swelled, flooding the lower city with unstoppable torrents of water. This was only the first of three waves, each compounding the devastation.

Fire Consumes the Ruins

As if the quake and tsunami were not enough, fires soon erupted across the city, igniting from candles, cooking fires, and toppled oil lamps left burning in homes and churches. Strong winds fanned the flames, turning Lisbon into a raging inferno that burned uncontrollably for five days.

Beyond Lisbon – A National Catastrophe

Lisbon was not the only Portuguese city affected by the disaster. Towns and villages across southern Portugal suffered severe destruction, and coastal areas experienced deadly tsunamis. The shockwaves were felt as far away as Spain, North Africa, and even the Caribbean, underscoring the unprecedented scale of the catastrophe.

The 1755 Lisbon Earthquake was more than a natural disaster—it was a seismic event that reshaped Portugal’s history, influencing urban planning, philosophy, and European thought, and leaving an enduring mark on Enlightenment discourse.
