What Western Hemisphere people spoke Nahuatl?

The people who spoke Nahuatl were primarily the Aztecs, also known as the Mexica. They were a powerful and influential group who dominated central Mexico in the 14th and 15th centuries.

However, it's important to note that Nahuatl wasn't limited to just the Aztecs. It was actually a family of languages spoken by various indigenous groups throughout Mesoamerica, including:

* Texcoco: A rival city-state to the Aztecs, with their own distinct dialect of Nahuatl.

* Tlaxcala: A city-state that was allied with the Spanish during the conquest of the Aztec Empire.

* Acolhua: A group who lived in the Valley of Mexico and had a close relationship with the Aztecs.

* Pipil: A group who migrated to El Salvador and Nicaragua and spoke a dialect of Nahuatl called Pipil Nahuatl.

So, while the Aztecs are the most well-known speakers of Nahuatl, it was spoken by many different groups across Mesoamerica.
