The final defeat
On 13 August 1521, Cuauhtémoc was captured after the siege of the Mexica capital. He—not Moctezuma II—was the ruler at this final stage. Mexico’s National Institute of Anthropology and History describes the last resistance at Tlatelolco.
The forces led by Hernán Cortés included Indigenous allies. Describing the conflict simply as a small European force defeating an undifferentiated Indigenous population obscures those political relationships.
Conquest was not disappearance
The fall was a decisive political and military defeat, involving severe suffering. It should not be reduced to a pleasant exchange of cultural influences. Equally, it should not be described as the disappearance of Indigenous people or the end of their histories.
Claims about later institutions, religion or cultural practices need their own evidence. A present-day custom cannot simply be assigned an origin in this one moment without investigation.
Read accounts critically
Ask who produced each account, in what language and for which audience. Distinguish a contemporary account, a later recollection and a modern reconstruction. Dramatic descriptions of sounds, thoughts or sunrise need evidence; they are not automatically historical facts.
Explore a bounded alternative
If a particular alliance or siege decision changes, explain who acts differently and why. A failed attack would not necessarily leave every political structure unchanged or prevent all later expeditions.
Label any fictional continuation and keep it separate from the documented capture of Cuauhtémoc.
