Spanish conquistadors—soldiers and adventurers like Cortés and Pizarro—conquered vast Aztec and Inca empires using superior weaponry, disease, and indigenous alliances. Conquest established Spanish colonial rule in the Americas and initiated catastrophic demographic collapse for indigenous populations.
From the Age of Exploration you already know how Spanish maritime expansion created knowledge of the Americas — what the conquistador era adds is the violent on-the-ground mechanics of how that knowledge was converted into empire. Conquistadors were not royal soldiers in a formal military hierarchy; they were entrepreneurs of violence. Men like Hernán Cortés and Francisco Pizarro financed their own expeditions, recruited their own forces, and operated under royal authority granted by contract. The spoils — gold, slaves, land — were theirs to divide. This profit motive shaped every decision they made.
The conquest of the Aztec Empire (1519–1521) is the paradigmatic case. Cortés arrived in Mexico with roughly 500 men facing an empire of millions. How did this work? Three factors combined. First, indigenous alliances: the Aztec empire had tributary peoples who resented Tenochtitlán's domination. Cortés recruited tens of thousands of Tlaxcalan and other warriors who saw the Spanish as potential liberators from Aztec tribute demands. Second, military technology: steel swords, armor, horses, and firearms were not individually decisive, but together they created psychological shock and tactical advantage in specific battlefield situations. Third, and most devastating, epidemic disease: smallpox and measles spread ahead of Spanish forces, killing populations with no prior exposure, sometimes collapsing political structures before soldiers even arrived.
The conquest of the Inca Empire (1532) illustrates the political dimension. Pizarro captured the emperor Atahualpa at Cajamarca while he was still consolidating victory in a civil war — the Inca empire was already fractured. Pizarro exploited the void. Atahualpa filled a room with gold as ransom; the Spanish executed him anyway. This pattern — exploiting existing political divisions, combining military confrontation with diplomatic maneuvering, and using captive rulers as instruments of control — was repeated across Mexico and South America as different groups of conquistadors extended Spanish reach.
The demographic consequences were catastrophic on a scale that is difficult to comprehend. Pre-conquest central Mexico may have had 20–25 million inhabitants; within a century, the population had collapsed to perhaps 1–2 million. The causes were multiple — epidemic disease, violence, forced labor, famine, and social disruption — but disease was the dominant factor. This demographic collapse reshaped everything: it created labor shortages that drove the slave trade, altered agricultural patterns, and left landscapes that Spanish settlers misread as "empty" wilderness. The conquest was not simply a military event but the beginning of a centuries-long transformation of American societies, ecologies, and economies — which you will trace further through the Columbian Exchange and Spanish colonial empire.
