Spanish conquest of the Aztec Empire

Spanish conquest of the Aztec Empire was the landmark military campaign between 1519 and 1521 that led to the fall of the Aztec Empire and established Spanish hegemony over central Mexico. Led by the ambitious conquistador Hernán Cortés, a small Spanish force exploited profound political divisions within Mesoamerica, forging critical alliances with rival indigenous states like Tlaxcala. The campaign culminated in the protracted and brutal Siege of Tenochtitlan, which resulted in the destruction of the capital city Tenochtitlan and the capture of the last tlatoani, Cuauhtémoc.

Background

In the early 16th century, the Aztec Empire, or the Triple Alliance, dominated central Mexico from its magnificent island capital, Tenochtitlan. Under rulers like Moctezuma II, the empire exerted control through a combination of military might, tribute collection, and ritualized warfare, creating resentment among many subjugated peoples such as the Tlaxcalans and the Totonacs. Concurrently, the Spanish Empire, following the voyages of Christopher Columbus, was expanding its presence in the Caribbean from bases like Santo Domingo and Cuba. Previous expeditions, including those led by Juan de Grijalva, had made contact with the Yucatán Peninsula coast, bringing back reports of a wealthy inland civilization. These reports, combined with Spanish desires for gold, territory, and converts to Catholicism, set the stage for a major expedition.

Spanish expedition and arrival

In February 1519, Hernán Cortés departed Cuba, defying orders from Governor Diego Velázquez de Cuéllar. His fleet landed first at Cozumel and then proceeded along the coast, where at San Juan de Ulúa he first received emissaries from Moctezuma II. A pivotal early event was the founding of Veracruz, where Cortés established a municipal government directly loyal to King Charles I of Spain. He then marched inland, decisively defeating the Tlaxcalans in battle before securing them as crucial allies against their mutual enemy, the Aztec Empire. In November 1519, Cortés and his combined force entered Tenochtitlan, where he was initially received by Moctezuma II. Tensions escalated, leading to the Noche Triste in June 1520, when the Spanish were forced to flee the city following an uprising after the Massacre in the Great Temple orchestrated by Pedro de Alvarado.

Fall of Tenochtitlan

Following their retreat during the Noche Triste, the Spanish regrouped at Tlaxcala. A devastating smallpox epidemic, introduced by the Europeans, swept through Mesoamerica, killing the newly ascended tlatoani Cuitláhuac and weakening Aztec defenses. Cortés spent months building a fleet of brigantines and consolidating his alliance with Tlaxcala, Huejotzingo, and other city-states. In May 1521, he launched a multi-pronged Siege of Tenochtitlan, with divisions commanded by Pedro de Alvarado, Cristóbal de Olid, and Gonzalo de Sandoval blockading the causeways into the city. The final Battle of Tenochtitlan was a grueling urban conflict marked by fierce street fighting and the systematic destruction of the city's infrastructure. The last Aztec ruler, Cuauhtémoc, was captured on August 13, 1521, effectively ending organized resistance.

Aftermath and consequences

The fall of Tenochtitlan marked the collapse of the Aztec Empire and the foundation of New Spain. Hernán Cortés began rebuilding the ruined capital as Mexico City, the new colonial capital. The Spanish instituted the encomienda system, granting indigenous labor and tribute to conquistadors, while Franciscans like Toribio de Benavente began widespread evangelization. The catastrophic demographic decline of the indigenous population, due to epidemics like smallpox, measles, and forced labor, was one of the most devastating consequences. Subsequent campaigns, such as those led by Cristóbal de Olid and Pedro de Alvarado, extended Spanish control over regions like Michoacán and Guatemala. The conquest also triggered vast wealth transfers to Europe, fueling the Spanish Golden Age.

Historical sources and perspectives

Primary sources on the conquest are multifaceted and often conflicting. Key Spanish accounts include the letters of Hernán Cortés to Charles V, the detailed history by soldier Bernal Díaz del Castillo in his True History, and the ecclesiastical perspective of Bernardino de Sahagún in the Florentine Codex. Indigenous viewpoints are preserved in works like the Florentine Codex, compiled by Bernardino de Sahagún with Nahua informants, and the Lienzo de Tlaxcala. Modern historiography, influenced by scholars like Miguel León-Portilla in The Broken Spears, increasingly emphasizes the role of indigenous allies and the catastrophic demographic impact, moving beyond narratives centered solely on Hernán Cortés and Spanish technological superiority.
