Conquests in the New World: Cortés, Malinche, and the Fall of the Aztec Empire (1519–1521)
The New World: Early References and Spanish Expansion
1503: Amerigo Vespucci, Italian explorer and financier, makes the first reference to the 'New World' — the continent later named after him (America).
1513: Vasco Núñez de Balboa crosses Central America to reach the Pacific, underscoring the vast scale of the newly encountered landmass.
Initial Spanish contact focused on the Caribbean islands; mainland civilizations remained largely untouched at first.
The lure of wealth spurred Spain to shift from exploration to conquest, laying foundations for a global empire.
Key figure: Hernán Cortés — ruthless conqueror whose actions helped shape the modern world in the Americas.
Hernán Cortés: Background and Early Career
Born in 1485 in Medellín, Spain, into modest lower nobility; precocious, adventurous, inspired by Columbus.
1504: While Vespucci’s pamphlet circulated in Europe, Cortés leaves Spain for the island of Hispaniola (present-day Dominican Republic and Haiti).
On Hispaniola, he rises through colonial administration ranks.
1511: Joins expedition to conquer Cuba; appointed secretary to Diego Velázquez, the island’s first colonial governor.
1518: Velázquez appoints Cortés to lead an expedition toward Mexico; Cortés seeks leadership rather than mere obedience, foreshadowing a bold, independent command.
The Making of a Conqueror: Strategy and Early Actions
Cortés disobeys Velázquez’s orders, turning an exploratory mission into a full-scale military conquest.
February 1519: Sets off from Cuba with 11 ships, roughly sailors, soldiers, and horses.
On the way to Tenochtitlan (Aztec capital in central Mexico), Cortés gains knowledge of local politics and forms alliances to bolster his campaign.
He is particularly effective at leveraging rivalries among indigenous peoples and exploiting divisions.
The Spaniards gain support from the Totonac people of Cempoalá and later from the Tlaxcaltecs after a brutal conflict; these alliances prove crucial for sustained military success.
The Aztecs and Moctezuma: Initial Encounters
The Aztec capital, Tenochtitlan, was a vast urban center with power over 400–500 allied states and a total population of about in the broader region.
Moctezuma II (Moctezuma) governs from Tenochtitlan; Cortés’s arrival triggers a diplomatic yet coercive interaction.
Cortés captures Moctezuma to establish a toehold of power within the city; this makes him a target of Aztec resistance and a focal point of uprisings.
Cholula: The First Major Brutal Clash
The Cholula massacre: A pivotal, brutal assault ordered by Cortés during the march to Tenochtitlan; roughly residents killed over two days.
The massacre demonstrates Cortés’s ruthlessness but also solidifies the Spaniards’ fearsome reputation and their ability to intimidate rivals.
The Road to Tenochtitlan: Movement and Battle Strategy
Cortés exhibits a talent for observation and manipulation of local rivalries; gains alliances with Tlaxcaltecs after defeating other indigenous groups, notably the Tlaxcaltec, who switch from foe to ally.
The Spaniards and Tlaxcaltecs march toward Tenochtitlan with a mix of diplomacy and force, aided by indigenous allies who resent Aztec dominance.
Cortés uses a combination of superior weaponry, indigenous support, and strategic diplomacy to outmaneuver a much larger Aztec force.
The Night of Sorrows and the First War Within
1519: Cortés enters Tenochtitlan; initially receives Moctezuma as a captive under the pretense of maintaining peace.
Early 1520: Cortés leaves Tenochtitlan to confront a punitive expedition sent from Cuba by Velázquez.
In his absence, Pedro de Alvarado leads the garrison, unleashing a brutal suppression of Aztec chiefs, which provokes a violent backlash from the city.
June 24, 1520: Cortés returns to Tenochtitlan; Moctezuma’s authority wanes as the city rebels against the Spaniards.
June 30, 1520: Spaniards flee the city under heavy fire; many die attempting to carry treasure; the event becomes known as the Night of Sorrows.
A smallpox epidemic weakens the Aztec forces just as Cortés regroups, giving the Spaniards a temporary strategic edge.
Otumba and the Turning Tide
After regrouping, Cortés defeats the Aztecs at the Battle of Otumba with the help of indigenous allies and superior tactics.
Cortés notes,
quote: "Our only security, apart from God, is our horses."
The Spaniards briefly separate from Moctezuma’s regency but retain control of the situation thanks to effective cavalry deployment against Aztec warriors.
The allied forces, including a significant Tlaxcaltec contingent, help Cortés push toward recapturing Tenochtitlan.
The Tlaxcala Alliance: Prophesied Support and Practical Help
The Tlaxcaltec alliance becomes pivotal in the eventual downfall of the Aztec Empire.
Xicoténcatl, lord of Tlaxcala, believes a prophecy that foretells foreign rulers from the east; he agrees to ally with Cortés.
The alliance provides fairly substantial military support and resources:
Cortés receives 300 women from Tlaxcala; in exchange, he offers textiles and salt.
The Tlaxcaltec alliance contributes thousands of warriors over time, a decisive factor in the siege of Tenochtitlan.
The Siege of Tenochtitlan (1521): Final Conquest
By 1521, Cortés’s forces, with the addition of an enormous indigenous army (roughly warriors), prepare for the siege.
Water supply is cut off in May 1521 by seizing Chapultepec aqueduct; this contributes to the city’s fatigue and vulnerability.
The Aztecs put up stubborn resistance; Cortés is temporarily captured in July 1521 and rescued by his captains after being wounded in the leg.
Aztec fortifications are rebuilt; the Spaniards and their allies face a renewed defensive effort.
A final assault is launched with a plan to fill in marshes with rubble to facilitate an attack.
August 13, 1521: Tenochtitlan falls; the Aztec capital is conquered and effectively ends Aztec political power in that region.
Casualties: roughly Spaniards killed versus as many as Aztecs killed during the siege and subsequent fighting.
Immediate aftermath: Cortés consolidates control over the former Aztec Empire; the conquest marks the beginning of a vast Spanish imperial domain across the Americas.
Aftermath and Legacy
Cortés becomes a major figure in the Spanish Empire, though his later years include legal and health troubles; he dies in 1547 at age 62, in a village near Sevilla, Spain, amid lawsuits and the repercussions of his expeditions.
The conquest of Tenochtitlan channels into a broader pattern of European imperial expansion in the Americas during the 16th century.
Cortés’s life also highlights personal and ethical complexities: his relationship with Malinche and other women, his ambition, and the violent means used to secure power.
Key figures connected to Cortés:
Malinche (Doña Marina): Aztec woman who becomes interpreter, partner, and mother to Cortés’s child; often cited as an essential agent in the conquest due to linguistic skill.
Catalina Suárez: Cortés’s early wife (married 1514 after he gains a promotion); their relationship reflects political alliances and Cortés’s personal life.
Isabel Moctezuma: Daughter of Moctezuma; Cortés’s consort for a time; the relationship underscores the political dimensions of courtly alliances.
Juana de Zúñiga: Cortés’s later wife (1529); he becomes a marquis, embedding his status within the aristocracy.

Broader implications:
The conquest demonstrates how rapid European expansion could be achieved through a combination of diplomacy, strategic alliances, military technology, and the exploitation of existing political rivalries.
The interactions created a complex cultural and demographic synthesis (early mestizaje) and set the pattern for colonial rule in the Americas.
The ethical and humanitarian costs were enormous, with massive indigenous devastation, slavery, forced labor, and cultural disruption that reshaped the region for centuries.
