    The idea

    The capture of Tenochtitlan in August 1521 marked the culmination of the Spanish conquest of the Aztec Empire. Hernán Cortés regrouped his forces in Tlaxcala and launched a meticulously planned siege. He cut off the city's fresh water supply by destroying the Chapultepec aqueduct and deployed thirteen purpose-built brigantines on Lake Texcoco to control the waterways, preventing Aztec resupply. The defenders, severely weakened by a devastating smallpox epidemic, fought fiercely under their new emperor, Cuauhtémoc. After 93 days of brutal street-by-street fighting and starvation, the city fell. Cuauhtémoc was captured while attempting to flee, leading to the formal Aztec surrender and the complete destruction of their capital.

    What earns the marks

    • Identify the role of Tlaxcalan allies in supporting the Spanish siege.
    • Explain the strategic importance of the brigantines on Lake Texcoco.
    • Describe the impact of the smallpox epidemic on the Aztec defenders' ability to resist.
    • Detail the tactics used by Cortés, such as cutting off the aqueduct and blockading causeways.
    • Note the capture of Cuauhtémoc as the definitive moment of Aztec surrender.

    Common mistakes and how to put them right

    • Claiming the Spanish captured the city solely due to superior weaponry.

      Put it right: Emphasise that disease, indigenous allies, and siege tactics were equally critical factors.

    • Confusing Moctezuma II with Cuauhtémoc during the final siege.

      Put it right: State clearly that Cuauhtémoc was the Aztec leader during the final defence and surrender of Tenochtitlan.

    • Stating the capture happened quickly after the Spanish arrived.

      Put it right: Explain that the final capture occurred in August 1521 after a prolonged 93-day siege, following the earlier Spanish expulsion.

    Exam tips

    • When evaluating the reasons for the Aztec defeat, ensure you balance Spanish military tactics with the devastating impact of smallpox.
    • Use specific details, such as the construction of the brigantines, to demonstrate precise knowledge of the siege.
    • Link the capture of the city directly to the collapse of the wider Aztec Empire to show an understanding of consequences.

From the siege box two branches emerge: one to the destruction of the Chapultepec aqueduct, cutting off fresh water, and one to the deployment of thirteen brigantines on Lake Texcoco to control the waterways. Both branches lead into a box noting the Aztec defenders were weakened by a smallpox epidemic. This leads to a box for 93 days of street-by-street fighting and starvation, then to a box for Cuauhtémoc being captured while attempting to flee, and finally to a box for the formal Aztec surrender and destruction of the capital.
