What happened
In 1519, drawn by rumors of gold and sophisticated inland cities, Hernan Cortes led an expedition of eleven ships and about 500 men to Mexico. The Aztec Empire, ruled by the Mexica people, dominated much of Mesoamerica from its capital Tenochtitlan, a city built on an island in a lake that, according to Spanish accounts, dazzled the conquistadors as unlike anything they had seen in Europe. Cortes marched inland, gathering thousands of native allies from peoples who resented Aztec rule, and formed a relationship with an enslaved Nahua woman named La Malinche, who worked as his translator and adviser.
Why it matters
Cortes's alliance-building with Aztec rivals turned what began as a small Spanish force into an army large enough to threaten the empire. The city that impressed his men on arrival would not survive two more years of war and disease.
How we know
The Library of Congress exhibit Cortes and the Aztecs and the Mariners' Museum's entry on Cortes both describe the expedition's size, the approach to Tenochtitlan, and the alliances Cortes built along the way, based on period Spanish accounts including Cortes's own letters to the crown.
