The Dike of Nezahualcoyotl: Tenochtitlan's Flood That Changed History
from Tenochtitlan: The Aztec Capital That Shocked the Spanish — Fexingo History · host Fexingo
In 1449, a devastating flood threatened to destroy Tenochtitlan. This episode tells the story of how the poet-king Nezahualcoyotl of Texcoco designed a massive dike — the albarradón — to save the island city. We explore the engineering challenges, the political alliance between Tenochtitlan and Texcoco, and the lasting impact of this monumental project. Discover how Nezahualcoyotl, already famous as a philosopher and ruler, also proved himself a brilliant hydraulic engineer. The dike not only protected the city but also helped regulate the delicate balance of Lake Texcoco's saline and fresh waters, enabling the chinampas system to thrive. We also touch on the legend that Nezahualcoyotl predicted the arrival of the Spanish. A story of ambition, collaboration, and survival on the water. #Nezahualcoyotl #Tenochtitlan #Texcoco #Albarradon #AztecEngineering #FloodControl #Chinampas #LakeTexcoco #HydraulicEngineering #TripleAlliance #Mesoamerica #AztecHistory #Mexica #Acolhua #1449 #BernalDiaz #FlorentineCodex #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo
