Overview

Hernán Cortés (born 1485, died 2 December 1547) was a Spanish conquistador and colonial administrator best known for leading the campaign that brought the Aztec Empire under Spanish control between 1519 and 1521. His expedition into central Mexico resulted in the capture of the imperial capital of Tenochtitlan and the creation of Spanish political institutions in the region that became New Spain.

Early life and imperial context

Cortés came from Medellín in Extremadura and received some formal education before sailing to the Caribbean. Like many early conquistadors, he first served in the settlements of Hispaniola and Cuba and later mounted an independent expedition to the mainland, operating within the broader expansion of the Spanish monarchy in the early 16th century.

The campaign in Mexico

Arriving on the Gulf coast in 1519, Cortés moved inland and established alliances with indigenous groups hostile to the Aztec Empire, notably the Tlaxcalans. His forces entered Tenochtitlan and captured the emperor Montezuma II during a period of intense negotiation and conflict. A combination of military tactics, indigenous rivalries, and disease — especially smallpox introduced by Europeans — contributed to the collapse of Aztec resistance by 1521. Events such as the Spanish withdrawal known as "La Noche Triste" and the subsequent siege of the city are central episodes in the conquest narrative.

Governance, correspondence, and later life

After the conquest Cortés assumed significant authority in the new colony, became an encomendero, and corresponded with the Spanish crown to justify his actions and request titles. He sent a famous series of letters describing his expedition to Emperor Charles V. Over time he faced legal challenges and contests over jurisdiction and wealth, returned to Spain to defend his position, and was eventually granted noble honors before his death in 1547.

Legacy and historiography

Cortés remains a figure of deep historical debate: praised in older European accounts as an agent of exploration and criticized for the violence, dispossession and cultural destruction that accompanied conquest. Cultural exchanges that followed included the movement of foods, plants and animals across the Atlantic; credit for introducing substances like cacao-based chocolate and vanilla to European markets is often associated with the early Spanish presence in Mesoamerica, though such transfers were complex and involved many actors.
