From the moment Spanish conquistador Hernan Cortés first found and confronted them, the Aztecs have fascinated the world, and they continue to hold a unique place both culturally and in pop culture. Nearly 500 years after the Spanish conquered their mighty empire, the Aztecs are often remembered today for their major capital, Tenochtitlan, as well as being fierce conquerors of the Valley of Mexico who often engaged in human sacrifice rituals.

Ironically, and unlike the Mayans, the Aztecs are not widely viewed or remembered with nuance, in part because their own leader burned extant Aztec writings and rewrote a mythologized history explaining his empire’s dominance less than a century before the Spanish arrived. Naturally, Cortes and other Spaniards depicted the Aztecs as savages greatly in need of conversion to Catholicism. While the Mayans are remembered for their astronomy, numeral system, and calendar, the Aztecs have primarily been remembered in a far narrower way, despite continuing to be a source of pride to Mexicans through the centuries.

As a result, even though the Aztecs continue to interest people across the world centuries after their demise, it has fallen on archaeologists and historians to try to determine the actual history, culture, and lives of the Aztecs from the beginning to the end, relying on excavations, primary accounts, and more.

Naturally, as the best known conquistador, Hernán Cortés (1485-1547) is also the most controversial. Like Christopher Columbus before him, Cortés was lionized for his successes for centuries without questioning his tactics or motives, while indigenous views of the man have been overwhelmingly negative for the consequences his conquests had on the Aztecs and other natives in the region. Just about the only thing everyone agrees upon is that Cortés had a profound impact on the history of North America.
