Aztlán

Aztlán (from Nahuatl: Aztlān, Nahuatl pronunciation: [ˈast͡ɬaːn]) is the legendary ancestral home of the Aztec peoples. Aztecah is the Nahuatl word for "people from Aztlan". The place Aztlan is mentioned in several ethnohistorical sources dating from the colonial period, and each of them give different lists of the different tribal groups who participated in the migration from Aztlan to central Mexico, but the Mexica who went on to found Mexico-Tenochtitlan are mentioned in all of the accounts. Historians have speculated about the possible location of Aztlan and tend to place it either in northwestern Mexico or the southwest US, although there are doubts about whether the place is purely mythical or represents a historical reality.

Nahuatl legends relate that seven tribes lived in , or "the place of the seven caves". Each cave represented a different Nahua group: the Xochimilca, Tlahuica, Acolhua, Tlaxcalteca, Tepaneca, Chalca, and Mexica. Because of their common linguistic origin, those groups are called collectively "Nahuatlaca" (Nahua people). These tribes subsequently left the caves and settled "near" Aztlán.

The various descriptions of Aztlán apparently contradict each other. While some legends describe Aztlán as a paradise, the Codex Aubin says that the Aztecs were subject to a tyrannical elite called the Azteca Chicomoztoca. Guided by their priest, the Aztec fled, and, on the road, their god Huitzilopochtli forbade them to call themselves Azteca, telling them that they should be known as Mexica. Ironically, scholars of the 19th century—in particular Alexander von Humboldt and William H. Prescott—would name them Aztec. Humboldt's suggestion was widely adopted in the 19th century as a way to avoid confusion between modern Mexicans and the pre-Hispanic civilization.
