Summary
Si Sheppard argues that the Spanish conquest of the Aztec and Inca empires was not a simple story of a few Europeans overpowering millions, but a collision of technology, diplomacy, disease, and deep internal political fractures. Cortés and Pizarro both succeeded by going straight to the emperor, capturing the top of a centralized hierarchy, and then using local rivals and subject peoples as the bulk of their armies.
He emphasizes that steel armor, horses, ships, and Old World military experience mattered, but so did the willingness of subject groups like the Totonacs, Tlaxcalans, Cañari, and others to ally with the Spaniards against their imperial overlords. In his telling, the decisive advantage was often not battlefield slaughter but social collapse: once Moctezuma II or Atahualpa was seized, the whole structure became vulnerable.
Sheppard also stresses contingency. If Cortés had died early, if Atahualpa had stayed at a distance, or if the Aztec and Inca had more time to adapt to cavalry and firearms, the outcome could have been different. But even then, he thinks disease, fragmentation, and the long-term pressures on these empires made durable resistance unlikely.
Key takeaways
- Sheppard says the Spanish conquered by seizing the emperor and governing through a decapitated hierarchy, not by brute force alone.
- He argues that horses, steel armor, and inherited Old World tactics gave the conquistadors a critical edge, especially in open terrain.
- He says indigenous allies were decisive: in the final assault on Tenochtitlan, the conquistadors were only about 0.5% of the force.
- He argues that disease and internal fragmentation meant the Aztec and Inca empires were vulnerable even if they had won some early battles.
- He says the conquest was highly contingent, but that the long-run European advantage in animals, disease, and institutions still favored eventual takeover.
Notable quotes
“A few hundred conquistadors show up to a new continent they know nothing about. Within a matter of years, they subjugate empires which have millions of inhabitants in them”
“The key term there, as you used it, was dispersal. The vulnerability of the Aztec and the Inca was that hierarchical nature of their society”
“once the emperor’s captured — Atahualpa for the Incas and Moctezuma for the Aztecs — what is it that they think is going to happen”
“Cortés knows that to take the city, he has to control the lake”
“the Europeans are learning from each other, but the natives are not learning from each other”
How the episode opens
Today I’m chatting with professor and military historian Si Sheppard. I want to talk to you about the conquest of the Aztec and the Inca Empires because these are some of the most shocking events in human history, unparalleled among all the military and diplomatic achievements ever made. A few hundred conquistadors show up to a new continent they know nothing about.
Within a matter of years, they subjugate empires which have millions of inhabitants in them. In the process of doing so, they are often winning battles where they are outnumbered 100 to 1, 1,000 to 1, and in many cases not even taking a single casualty. They’re doing this while upwards of 99% of their fighting forces are made up of the very natives that they’re going to subjugate.
I wanted to have you on to talk about something this episode. We’re not going to focus on it, we’re mostly talking about history here, but people think of AI takeover as this crazy sci-fi scenario but this would not be the first time in history that an alien force, with motivations that the natives don’t understand, is able to use diplomatic cunning and technological advantages to outmaneuver and then take over a much larger and well-established order. I wanted to have you on to understand what happened here.
First, I would love to hear the stories. What did Cortés do? What did Pizarro do?
How did these conquests actually go down? Thank you. It’s a great pleasure to be here.
Yes, we’re talking about the birth of our modern world, which played out between 600 to 500 years ago and created the modern globalized community that we all participate in today. It began in the 15th century when Europe, backed up against the wall of the Atlantic, under immense pressure from external forces and cut off from the core economic power bases of the East — the sources of the spice and silk that had driven the global economy historically throughout Eurasia — was finally forced to innovate.
