Where were the Aztecs located?
Teotihuacan Teotihuacan , also written Teotihuacán (] ,    ), is an ancient Mesoamerican city located in a sub-valley of the Valley of Mexico, located in the State of Mexico 40 km northeast of modern-day Mexico City, known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas.
Aztec Aztec culture ( ), also known as Mexica culture, was a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521, during the time in which a triple alliance of the Mexica, Texcoca and Tepaneca tribes established the Aztec empire. The Aztec people were certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. The Aztec have also referred to themselves as the Meshika or Mehika.
