Aztecs, an Indian people who dominated Mexico at the time of the Spanish conquest in 1521. Their capital city was Tenochtitl√°n (now Mexico City). They called themselves Tenochcas or Mexica. The term "Aztec" comes from the name of their legendary home. In a broader sense, "Aztec" is applied to their civilization, which flourished in Mexico during the 14th, 15th, and early 16th centuries.

The Aztecs were short, sturdy people with almond-shaped eyes, dark, coarse hair, and brown skin. They spoke Nahuatl, a language of the Uto-Aztecan family. Descendants of the Aztecs form a large part of the Indian population in and around Mexico City, and the Nahuatl language is still spoken.
