Siege of Tenochtitlan

Cortés initiated the final siege of Tenochtitlan by dividing his forces to attack along the three main causeways (Tacuba, Tepeyac, and Iztapalapa), cutting off the city’s access to food, water, and reinforcements. The Spaniards, supported by Tlaxcalan and Texcocan allies, systematically destroyed aqueducts and blockaded supply routes, starving the city into submission. This marked the beginning of attritional warfare, where the Aztecs, led by Cuauhtémoc, resisted fiercely but were gradually weakened by famine and disease.

Fall of Tenochtitlan: Final Resistance and Capture of Cuauhtémoc

The Siege of Tenochtitlan reached its climax. As the Spanish and their Tlaxcalan allies closed in, the Quetzal Owl Warrior—an Aztec warrior adorned in ritual regalia—appeared as a symbol of defiance, rallying the last defenders of the city. Despite fierce resistance, the Spaniards captured Cuauhtémoc, the final Aztec emperor, after he was dragged from a canoe while attempting to flee. His capture marked the fall of Tenochtitlan, ending the Aztec Empire. The city, already devastated by months of siege, starvation, and warfare, was left in ruins. The survivors, including refugees, fled across the causeways as Cortés consolidated Spanish control, laying the foundation for New Spain.
