The Migration from Aztlán
On the timeline · around c. 12th–14th centuries CE ·
What happened
By their own tradition, the Mexica set out from a mythical northern homeland called Aztlán — the source of the name 'Aztec.' Their god Huitzilopochtli, carried as an idol by his priests, is said to have guided them on a long migration south into the Valley of Mexico.
Why it matters
This origin story shaped Aztec identity and destiny. The very name 'Mexica' — the root of 'Mexico' — comes from this wandering people who believed a god was leading them to a promised land.
How we know
The migration is known only from later Mexica chronicles and painted codices, which blend history with myth; Aztlán has never been located.
