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 in the 14th, 15th and 16th centuries, a period referred to as the late post-classic period in Mesoamerican chronology.Aztec (Aztecatl) is the Nahuatl word for "people from Aztlan", a mythological place for the Nahuatl-speaking culture of the time, and later adopted as the word to define the Mexica people.The "Aztec" term was forged by the Occident literature as for Mexicas. In the Mexica's beliefs Mexico-Tenochtitlan was founded in Aztlan, an isle in the middle of a lake, and its inhabitants were called Aztecatl from where the word Aztec was originated Often the term "Aztec" refers exclusively to the Mexica people of Tenochtitlan (now the location of Mexico City), situated on an island in Lake Texcoco, who referred to themselves as Mexica Tenochca or Colhua-Mexica.
