Founding of Mexico City: From Tenochtitlan (1325) to Modern Metropolis
Tenochtitlan, the Aztec capital, was founded in 1325 on an island in Lake Texcoco, in the Valley of Mexico. It became one of the world's largest cities (200,000+ at peak). After the Spanish conquest (1521), it was razed and rebuilt as Mexico City — the capital of New Spain, then independent Mexico.
Founding Legend (Mexica / Aztec)
- Prophecy: Huitzilopochtli (sun/war god) told Mexica to settle where they saw an eagle on a cactus devouring a snake.
- Site: Island in Lake Texcoco — matched vision (c. 1325).
- Engineering: Chinampas (floating gardens), causeways, aqueducts (Chapultepec), dikes (Nezahelcoyotl).
Spanish Conquest & Transformation (1519–1521)
- Cortés besieged Tenochtitlan (May–Aug 1521); smallpox, blockade, native allies (Tlaxcala) decisive.
- City destroyed; stones reused for Spanish colonial buildings (Cathedral, National Palace on Templo Mayor site).
- Lake drained over centuries (flood control) → modern city on dried lakebed (subsidence, water crisis).
