Spanish Conquest and Its Aftermath

In 1519, Hernan Cortes landed on the Mexican coast with about 500 Spanish soldiers, plus horses, cannon, and steel weapons that the Mexica had never seen. Within two years, with support from tens of thousands of native allies (especially the Tlaxcalans, who were enemies of the Aztec) and aided enormously by the spread of smallpox and other diseases, Cortes captured Tenochtitlan and effectively ended the Aztec Empire. The conquest is often told as a story of Spanish military genius; modern scholarship emphasizes the indigenous coalitions that did most of the fighting and the catastrophic effects of European diseases on populations with no prior immunity.

The aftermath was devastating. Estimates of pre-conquest indigenous populations vary widely, but most scholars now think Mesoamerica had perhaps 25 million people in 1500. Within a century, due to disease, warfare, forced labor, and dislocation, the indigenous population had fallen by 80-90 percent. Spanish colonization imposed Catholicism, the encomienda labor system, and new economic structures focused on mining and large estates. Indigenous languages, religions, and political systems were systematically suppressed, though many persisted in adapted forms. Mexican identity is fundamentally mestizo, blending indigenous and Spanish heritage in language, food, religion, and visual culture.

Indigenous resistance and cultural persistence continued for centuries. The Pueblo Revolt of 1680 expelled Spanish colonists from New Mexico for over a decade. Maya peoples maintained independent cities into the 17th century. Throughout the colonial period, indigenous communities preserved languages, traditions, and oral histories alongside imposed Catholic practices. Modern Mexico has a more complex relationship with its indigenous past than 19th-century narratives suggested. National symbols like the Mexican flag and the Virgin of Guadalupe blend pre-Columbian and Catholic elements. Modern scholars and indigenous activists have actively recovered pre-Columbian history and assert indigenous rights and cultural heritage.

The Spanish conquest is one of the most consequential events in human history, comparable to the Roman conquest of Gaul or the British colonization of India. The next lesson covers the longer legacy of Mesoamerican civilizations and how they continue to shape the modern world.
