It has been a question that makes me wonder, since the very first time I read about the history of the Aztecs. In the fall of Tenochtitlan, as commonly known, the Tlaxcalans (Tlaxcaltecs) was the major force, accompanied with many indigenous factions (including even factions in the Triple Aliance itself!), summed up to many 100,000s. When compared with the Spanish troops, which had only around 500-1000 men, the Spanish force was very very tiny.

Given the above facts, it is somewhat counterintuitive that, after the fall of Tenochtitlan, Spain instead of Tlaxcala seemed to be the primary dominant power in the territory, and Tlaxcalans played a more passive role (even in the process of the conquest the Tlaxcalans seemed to play a subordinate role to the Spanish, not at an equal status, despite being major force).

Why did the conquest end up this way?

When Cortez was fighting the Aztecs, there was a rough, three way balance of power, between the Aztecs, the Tlaxcalans, and the Spaniards. The Aztecs lost because they were on the wrong "side" of a three-way fight, and were pretty much destroyed. That left the Spaniards and the Tlaxcalans as "equals" for the time being.

But afterward, the Spanish sent reinforcement of men, and particularly artillery, from Cuba. With these reinforcements, the Spaniards were stronger than the Tlaxcalans, whom they treated as "junior partners."

In the subsequent fighting e.g. in Central America, the Tlaxcalans were "allied" with the Spanish against other native peoples. More to the point, the Tlaxcalans did not receive "reinforcements" by making common cause with those other native people vis-a-vis the Spanish.

  • This is a plausible explanation for Spanish dominance in Mesoamerica. Perhaps the smallpox epidemic also contributed to the Spanish dominance in which it reduced very large native population so the natives had less power to resist the Spanish power. Besides military, Spanish culture (e.g. Catholicism) and administration system also dominated too. Thanks!

  • @armamoyl: "Smallpox" could have been another factor tipping the balance of power in favor of the Spanish, and against the Tlaxcala. But in any event, time was not on their side.

Tlaxcala was strong enough to be independent of Tenochtitlan and the Triple Alliance, while combating them in the regular "flower wars" which provided sacrificial victims and opportunities for valor. However, unlike the Mexica state, Tlaxcala was not attempting to expand.

As Cortés moved inland, he chose to go through Tlaxcala instead of Cholula at least in part because the latter was a Mexica subject. In Tlaxcala the Spaniards won two battles and successfully defended themselves against a nighttime attack. Tlaxcalan caciques were forced to agree to provide Cortes with soldiers, women, and food. The Tlaxcalans had been able to stay free of the Mexica, but they became subjects of Spain. The nearly contemporary Lienzo de Tlaxcala includes this image of Tlaxcalan King Xicotencatl the Elder receiving Cortés and Malinche as they contemplate their assault on Tenochtitlan:

Possibly related to its role as the first native force allied with Spain, Tlaxcala became the seat of Mexico's first bishopric. Some Tlaxcalans were later settlers in the Gran Chichimeca.

  • How did Tlaxcala become Spain's subject? Why didn't the Tlaxcalans manage to overcome the Spanish given that they had many 100,000s soldiers?

  • I think the manner in which Cortés defeated the Tlaxcalans is worth another question. I couldn't tell you off the top of my head. Commented Nov 30, 2018 at 15:56
  • @armamoyl: The Spanish had advantages in artillery, gunpowder and armor, to the point where 1,000 Spanish had equivalent fighting power to 40,000 (not 100,000s) Tlaxcalans, and 40,000 Aztecs. In power terms, it was approximately one-third, one-third, one-third, despite the disparity in numbers. So the allied "two thirds" won.
