Spain and Portugal, exploration and conquest 
Setting the stage
The era is a pivotal moment in world history: late 15th–16th centuries, often labeled as the beginning of globalization or the Atlantic world.
Norse exploration reached North America around a thousand CE, but the material emphasizes that the major transformative actions came later from Portugal and Spain.
Portugal’s location, with Lisbon as a major port on the western edge of Europe, positioned them to challenge Venetian power in trade.
The immediate setting: a small, ambitious kingdom aiming to break control of Mediterranean trade routes and to expand Christian influence alongside economic interests.
Portugal and Henry the Navigator
Prince Henry the Navigator becomes a central figure in early exploration, though he didn’t sail himself much.
His program focused on sponsoring voyages down the West African coast, seeking wealth and Christian conversion.
Religious motive highlighted: his stated aim to spread the Christian faith and save souls.
The Portuguese maritime program boasted advanced skills:
Use of maps from across Europe to plan routes.
Introduction of the triangular latine sail, enabling sailing against the wind.
Development of lighter ships, the caravels, well-suited for coastlines and exploration.
Tools and technology of exploration
The caravel as a key innovation: lighter, versatile for coastlines and long voyages.
The latine (lateen) sail enabling maneuverability against prevailing winds.
Maritime knowledge combined with new navigation tools and map usage supported extended European reach.
Spain’s unification and religious climate
1469: Marriage of Ferdinand of Aragon and Isabella of Castile unites powerful kingdoms, laying foundations for modern Spain.
Isabella’s religious zeal, including support for the Spanish Inquisition beginning around 1480, creating a climate tied to Reconquista ideals.
Over roughly two and a half decades, the monarchs consolidate power and fund expansion and trade with the East.
Isabella’s religious policy framed as a vehicle for spreading Catholicism and completing the Reconquista (taking land back from Muslims).
Side note: Catherine of Aragon, Isabella and Ferdinand’s daughter, later marries Henry VIII of England, illustrating the interconnected dynastic politics of Europe.
The three G’s: God, Gold, and Glory
God: religious motivation intertwined with conquest, conversion, and reconquest.
Gold: wealth, trade routes, resources, and the lure of riches; the explorers’ reports back home (Probanzas de Merito) framed exploration as a path to wealth.
Glory: national prestige, personal advancement, and titles for explorers (e.g., Columbus becoming nobility).
The sources emphasize that religious zeal was a genuine motive, not mere pretense, especially in Spain and Portugal.
Columbus and the 1492 voyage
1492 is a turning point: Columbus sails in August with three ships (Nina, Pinta, Santa Maria) and reaches land after ~6 ext{ weeks} \approx 3{,}000 ext{ miles}
He lands in The Bahamas, on an island named Guanahani by locals; Columbus renames it San Salvador.
He believed he’d reached the Indies off the coast of Asia, hence referring to natives as Indios Indians and continuing to think he’d found a westward passage to Asia.
The voyage marks the start of sustained Spanish contact with the Americas, and Columbus returns with royal backing for further expeditions and settlement on Hispaniola.
The 1493 letter describing the discoveries proliferates across Europe via copies, translations, and prints, shaping public imagination and royal expectations.
The letter’s content is self-serving and promotional, illustrating how primary sources can reflect bias and the era’s mindset.
The expedition’s goals included a potential new crusade funded by the anticipated wealth from new territories (linking God and gold).
The native populations encountered by Columbus were often described with dismissive language that obscured their humanity and complexity.
Amerigo Vespucci and the naming of America
Vespucci’s voyages (roughly 1499–1502) argued that the land Columbus reached was not Asia but a completely new continent.
Vespucci’s accounts gain wide publication, generating detailed public interest in the new world.
German cartographer Martin Waldseemüller, in 1507, used Amerigo’s name for the new landmass on a map, giving rise to the name "America".
Portuguese empire vs. Spanish empire: routes and strategies
Portugal’s early focus: establishing a sea-based empire to control sea routes and trading posts rather than large land empires.
Strategic landing points along the Atlantic: the Canaries, Cape Verde, the Azores, and Madeira functioned as debarkation points and bases for further expansion.
From these bases, they extended down Africa’s west coast toward the Congo, then across the Indian Ocean to India, and eventually to the broader Asia–Pacific region.
Portugal also claimed Brazil’s coast after early Atlantic explorations (through a European framework that favored maritime domination and trade control).
The core strategic difference: Portugal sought a global trading network with control over sea routes; Spain pursued land-based empire-building in the Americas.
Slavery, sugar, and the Atlantic economy
The Atlantic slave trade deepens as Portuguese exploration expands, with slavery tied to the growth of sugar plantations.
Sugar becomes the engine of the Atlantic slave trade, driving the importation of enslaved Africans to support plantation economies on Atlantic islands and the broader Atlantic world.
The sources describe enslaved labor as a form of “much needed human capital,” underscoring the cold economic calculus that underpinned dehumanization.
This period marks the emergence of a gargantuan plantation complex across the Atlantic, built on forced labor and linked to global trade networks.
The conquest era: major conquistadors and their campaigns
Hernán Cortés (arrived in the Caribbean by 1504; reached the Aztec world around 1519):
Captured Moctezuma and seized Tenochtitlan by 1521 after forging alliances (notably with the Tlaxcalans, who provided as many as 200{,}000 fighters).
The city’s fall was aided by disease (smallpox) and internal native divisions as much as by Spanish force.
Doña Marina (La Malinche) acted as translator and cultural broker; she bore Cortés’ child, Martín, and her role illustrates how native actors were integral to conquest.
The conquest culminated in the renaming of Tenochtitlan as Mexico City, symbolizing a transfer of power and culture.
Francisco Pizarro (expeditions starting 1509; conquest accelerated in the 1520s):
Captured the Inca emperor Atahualpa in 1532 and executed him in 1533 after a huge ransom; founded Lima in 1533 as the new capital.
Like Cortés, Pizarro faced internal rivalry and resistance, and he was ultimately assassinated by a rival Spaniard in 1541.
Hernando de Soto (1539–1542) and explores through the Southeast United States:
Traversed vast areas (Florida to the Carolinas and beyond), aiming for gold but finding disease and hardship instead.
Francisco Vázquez de Coronado (1540–1542):
Led an expedition into the American Southwest in search of the fabled Cíbola (city of gold).
Engaged in conflict with the Tiwa and other groups but found no gold or silver, ending financially unsatisfied and bankrupt.
A more nuanced view of conquest
The sources contrast the old narrative of unambiguous European superiority with a more complex reality:
Native polities were often in conflict with one another, creating openings for European intervention.
Alliances with native groups (e.g., Tlaxcalans) were essential for Spanish triumphs, showing it was not simply a matter of Spaniards vs. natives.
Disease, especially smallpox, caused catastrophic native mortality, often eclipsing the impact of weapons.
Native people were not just passive victims or mere instruments; translators and cultural brokers (like Malinche) shaped outcomes and decisions.
Rivalry among Spanish factions and explorers added another layer of complexity to the conquest dynamics.
The big picture: consequences and the birth of a global system
The age of exploration reveals intense ambition fueled by God, gold, and glory, embedded in new technologies (the caravel and lateen sails).
The era marks the start of a global trading system and the “Atlantic world,” where Europeans, Africans, and Native Americans intersected in new ways.
The financial and resource-driven logic of European expansion depended on exploiting pre-existing Native conflicts, upon mass disease, and on native labor and knowledge.
The era reshaped maps, economies, and identities, creating a new global order that would influence world history for centuries.
Reflection and historiography
How does knowing the role of alliances, disease, and native translators change our view of the word conquest?
The narrative moves away from “heroes vs. villains” and toward a more intricate web of motivations, power dynamics, and unintended consequences.
Considering the ethical implications: the exploitation inherent in creating empires, the forced labor of enslaved people, and the enduring legacies of these early contacts.
Real-world relevance: the origins of globalization, cross-cultural contact, and the long-term consequences for indigenous populations and African diasporas.
