The Nahua and Aztec people are often considered the same, but there are some distinctions to be aware of. The Nahua are a group of indigenous people who speak the Nahuatl language. This group includes various ethnicities and communities, one of which is the Aztecs.
The Aztecs, specifically, were a powerful civilization that dominated central Mexico in the 14th to 16th centuries. They are the most well-known Nahua group due to their vast empire and significant cultural impact. However, not all Nahua people are Aztecs. The Nahua encompass a broader range of communities and ethnic groups that share the Nahuatl language and certain cultural traits.
In summary, while the Aztecs are a subset of the Nahua people, the terms are not entirely interchangeable. The Nahua include a wider array of groups, each with their own unique histories and cultural practices.
