The Fall of Tenochtitlan and Colonial Conquest
Spanish forces and numerous Indigenous allies captured the Aztec capital, as epidemics, siege, and local politics together reshaped Mesoamerica.
The story
In 1521, Spanish forces led by Cortés and numerous Indigenous allies besieged and captured Tenochtitlan. Communities such as Tlaxcala chose to join the fighting because of local rivalries and interests; colonial conquest cannot be simplified into a small number of Europeans defeating the entire Americas on their own. Smallpox, hunger, siege, and warfare together caused immense casualties, and the central Aztec government collapsed. The Spanish subsequently built a colonial capital on the existing city, and taxation, missionary activity, and forced labor changed local society. Indigenous languages, families, and political action continued, however; conquest did not make their cultures disappear altogether.
Elsewhere in the world
Atlantic voyages brought pathogens, armies, and supplies into Mesoamerica, while Europe was also undergoing the Reformation and imperial rivalry.
