Aztec Sacrifices: Sources Cite 20,000 Annual Victims

Aztec Sacrifices: The Figure That Reopens the Conquest Narrative

According to a circulating account in the current debate, the Mexica Empire sacrificed captives daily to ensure the sun rose each morning. Some sources estimate 20,000 victims per year, with towers of skulls at the base of the Templo Mayor that included women and children. This disputed figure is central to a debate that has been ongoing for 572 days, pitting two irreconcilable narratives against each other regarding the fall of Tenochtitlan.

The discussion begins with an uncomfortable premise: was ritual cannibalism a nutritional necessity or a device of political terror? Some argue, citing Marvin Harris, that the absence of large mammals and livestock made human flesh the most complete available protein source. The counter-argument is swift: the Aztecs raised turkeys and xoloitzcuintle dogs, fished, and gathered insects. Reliance on meat does not hold up.

Why Neighboring Peoples Allied with Cortés

The analysis becomes more robust when focusing on military aspects. Four hundred Spanish soldiers did not conquer a territory of millions alone. They succeeded with the support of peoples subjected to Mexica terror, who provided the vast majority of the military force. The question is whether they allied out of antiestéticar of sacrifice or simply to shed a yoke. The latter interpretation gains weight: ritual sacrifice was part of their own culture, not something they outright rejected.

Bernal Díaz del Castillo’s chronicle describes how, after the city fell, it was the indigenous allies who razed it, driven by hatred accumulated over generations. According to this account, the Spanish soldiers watched without being able to intervene. This detail dismantles the image of an exclusively Spanish conquest and an exclusively Spanish massacre.

The Demographic Collapse: Epidemics, But Not Only

Estimates of the pre-Hispanic population range from 3 to 5 million inhabitants according to conservative figures, up to 25 million according to higher estimates. The wide margin makes any conclusion shaky. One author cited in the debate, Gibson, limits his calculations to the Valley of Mexico, where density was higher. Critics argue that extrapolating that density to the rest of the territory is a fallacious exercise.

The demographic collapse is attributed to epidemics, but one participant argues that the common denominator of all factors—social organization, hierarchies, economy, health—is the presence of the Spanish. Without it, the phenomenon cannot be explained. The debate is not about whether there was a catastrophe, but how much of it was biological and how much political.

The Clash of Figures No One Resolves

Pre-Hispanic population figures are the exact point where the analysis stalls. The highest estimates give pre-Hispanic Mexico a density superior to Ming China, which is considered impossible. The lowest equate it to other Neolithic societies. Between these extremes, available evidence—tribute records, fragmentary censuses—does not allow settling the dispute. The disagreement is not ideological; it is archaeological.
