Tenochtitlan → Mexico City: The Spanish Rebuilt, Not Renamed

The Spanish did not simply rename Tenochtitlan. They destroyed it and built a new city atop the ruins — Mexico City.

The Sequence

1. 1325: Mexica (Aztecs) found Tenochtitlan on Lake Texcoco island. Name: "Place of the Mexica" (tetl=stone, nochtli=prickly pear, tlan=place).
2. 1519–1521: Cortés arrives; siege destroys city (smallpox, artillery, indigenous allies).
3. 1521 onward: Spanish lay out Mexico City on grid plan over Tenochtitlan's rubble. Main plaza (Zócalo) = former ceremonial center. Cathedral on Templo Mayor stones.

Why "Mexico"?

• From Mēxihco (Nahuatl) — the Mexica's own name for their heartland.
• Spaniards adopted the indigenous toponym for the new capital — practical continuity.
• "New Spain" (Nueva España) became the viceroyalty name.

What Survived

• Canal/street alignments (some follow causeways).
• Market system (tianguis → modern mercados).
• Chinampa agriculture (Xochimilco).
• Nahuatl place names citywide (Coyoacán, Chapultepec, Tlatelolco).

Archaeology Today

Templo Mayor excavations (1978–present) reveal Tenochtitlan beneath the cathedral. Metro digs constantly uncover Aztec layers.

Mexico City is a palimpsest: Tenochtitlan's bones, Spanish grid, modern megacity — all alive at once.
