3. The Spanish Conquest of the Aztec Empire (1519-1521)
In 1519, Spanish conquistador Hernán Cortés led an expedition to Mexico, aiming to conquer the Aztec Empire. Despite being vastly outnumbered, Cortés formed alliances with indigenous groups who resented Aztec rule, notably the Tlaxcalans. On November 8, 1519, Cortés and his forces entered Tenochtitlán, the Aztec capital, where they were initially welcomed by Emperor Moctezuma II, who mistook them for divine envoys. Cortés took advantage of this hospitality, capturing Moctezuma and asserting control over the city. However, tensions escalated, leading to the Aztec revolt and the Spanish retreat on June 30, 1520, known as “La Noche Triste.” Cortés regrouped with his allies and returned in May 1521, laying siege to Tenochtitlán for three months. The city fell on August 13, 1521, marking the end of the Aztec Empire. The conquest was facilitated by superior weaponry, strategic alliances, and the devastating impact of European diseases like smallpox, which decimated the indigenous population. This event dramatically reshaped the Americas, leading to Spanish colonization and the profound transformation of indigenous societies (history.com).
