Aztlan, the mythical homeland of the Aztecs, described as a paradisiacal island of origin from which the Mexica people began their sacred migration to the Valley of Mexico. We examine historical accounts, cultural symbolism, scholarly debates, and modern reinterpretations of Aztlan as both a real and mythic place. Though its precise location remains unknown, Aztlan continues to inspire as a powerful emblem of identity, heritage, and the journey from myth to empire.
