Hernán Cortés (1485–1547) catalyzed transformations that reshaped the Americas. His 1519–1521 campaign against the Aztec Empire initiated three centuries of Spanish hegemony, leaving legacies still evident today.
Cortés exploited internal divisions—subject peoples (Tlaxcalans, Totonacs) allied with him against Mexica rule. Tenochtitlan fell August 13, 1521, after a 93-day siege. The empire's collapse removed the dominant Mesoamerican power, creating a vacuum Spain filled.
Spanish became the administrative, liturgical, and commercial language. Catholic missionaries (Franciscans, Dominicans, Jesuits) converted millions—often syncretically, blending Indigenous and Christian practices (e.g., Virgin of Guadalupe). Today, ~425M Spanish speakers and ~480M Catholics in Latin America trace this imposition.
Cortés distributed encomiendas—grants of Indigenous labor—to his men. Natives owed tribute/labor in exchange for "protection" and Christianization. Abuse, overwork, and Eurasian diseases (smallpox, measles) caused catastrophic population decline: central Mexico's population dropped from ~25M (1519) to ~1M (1600).
Cortés established Mexico City atop Tenochtitlan as capital of New Spain. He instituted cabildos (town councils), audiencias (courts), and the viceregal system. The 1535 Viceroyalty of New Spain governed from California to Costa Rica.
Silver from Zacatecas and Potosí flowed to Manila (via Acapulco) and Seville, linking Asia, Americas, and Europe. New World crops (maize, potato, tomato, cacao) transformed global diets; Old World livestock, wheat, and sugar reshaped American landscapes.
Mestizaje—biological and cultural mixing—created new identities: mestizo (Indigenous-European), mulato (African-European), zambo (African-Indigenous). Syncretic art, cuisine, music, and spirituality emerged.
Cortés is reviled as a destroyer of civilizations and celebrated as a founder of modern Mexico. His bones rest in Mexico City's Hospital de Jesús—which he founded—embodying the contradiction.
