Aztl n is the Aztec/Mexica place of origin in Northern Mexico — perhaps in the area of the present-day southwestern US states or perhaps an island in part of the modern Mexican state of Nayarit.
The literal meaning is: near the cranes, from azta cranes + tlan near.
It also gives its name to several Hispanic political movements in the United States, such as the self-styled Revolutionary Council and Provisional Government of Aztl n and MEChA, also known as Movimiento Estudiantil Chicano de Aztl (Chicano Student Movement of Aztl n). In this connection, it often refers to irredentist ambitions of independence or union with Mexico for those southwestern US states which Mexico controlled prior to the Treaty of Guadalupe Hidalgo of 1848.
