How Conquistadors Conquered the Aztecs - Si Sheppard

Dwarkesh Patel

Conquistador success against the Aztecs relied primarily on steel weapons, horses, and psychological tactics rather than firearms. Steel armor and swords proved far more effective than indigenous weapons made of wood, stone, and obsidian, while horses—animals unknown to the Aztecs—provided decisive military and logistical advantages.

Summary

According to Si Sheppard, the popular misconception that firearms were crucial to conquistador victories is incorrect. While indigenous peoples initially feared firearms, they quickly recognized that the long reload times and limitations of 16th-century guns made them relatively ineffective in combat. The true technological advantage came from steel weaponry. Conquistador swords made of Toledo steel, used as stabbing weapons, proved far superior to indigenous chopping weapons made of wood, stone, and obsidian volcanic glass. Steel armor and helmets provided crucial protection against local weapons.

Beyond weaponry, Cortes employed sophisticated psychological warfare, carefully hiding his dead from indigenous forces to prevent them from realizing they had achieved military victories in hand-to-hand combat. However, the most decisive advantage was the horse. With no local analogues—horses had become extinct in the Americas despite originating there—indigenous peoples lacked both the animals themselves and any cultural, economic, or military integration of such creatures. While the Incas had llamas as pack animals, the Aztecs had only domesticated turkeys and Chihuahuas. Conquistadors additionally brought large armored fighting mastiffs trained as combat animals. Horses enabled shock cavalry tactics that could break through indigenous formations unprepared for such tactics, and provided rapid retreat capability when needed.

Key Insights

  • Firearms were not significantly important to conquistador success because indigenous peoples quickly recognized that long reload times and gun shortcomings made them ineffective once the initial shock wore off.
  • Steel was the critical technological advantage, as conquistador Toledo steel swords and armor were far more effective against indigenous weapons made of wood, stone, and obsidian than firearms were.
  • Cortes deliberately buried his dead under houses to hide casualties from indigenous forces, preventing them from recognizing their own tactical victories and maintaining psychological dominance.
  • Horses were the most vital weapon conquistadors brought, as they had no local equivalents—horses had become extinct in the Americas—and were not integrated into indigenous military, economic, or cultural systems.
  • Shock cavalry using horses could break through indigenous formations lacking both the training and discipline to withstand mounted charges, and horses provided superior retreat speed if conquistadors needed to withdraw.

[0:00] Firearms weren't really that important. Once the indigenous peoples got over the shock, they realized, given the very long reload times and the shortcomings of the firearms of the time , that they were not that significant on the battlefield, but steel was critically important. Local weapons were made of wood, stone, and obsidian—a volcanic glass that becomes razor-sharp when sharpened, making it a very dangerous cutting weapon. But against the steel armor and especially the steel helmets worn by the conquistadors, it was much less effective. The conquistadors relied on the [0:30] military traditions of the old world, reaching back centuries, in particular, using long swords made of Toledo steel. They used them as stabbing weapons to destroy…
