The Aztecs and other Nahuatl people of ancient Mesoamerica all claimed to be descendents of people who migrated from a place called Aztlán. According to Nahuatl legends, the people of Aztlán lived in “the place of the seven caves,” or Chicomoztoc. It’s believed that the seven caves each represent a different Nahua tribe, including the Xochimilca, Tlahuica, Acolhua, Tlaxcalan, Tepaneca, Chalca, and the Mexica.

The name Aztec comes from the Nahuatl word Aztecatl, which means “the people from Aztlán.” Stories describe Aztlán as a paradise, but others include tales of tyrannical rulers called the Azteca Chicomoztoca.

Today, Tenochtitlan is Mexico City, one of the most populous cities in the world at 21 million residents.
