Aztlán

← Encyclopedia

A single strip of fig-bark paper, folded like an accordion into some twenty-two leaves, opens the visual record of where the Mexica came from. It is drawn in black line alone, without color, by an unnamed Nahua painter in the years just after the Spanish conquest of Tenochtitlan — most likely between 1530 and 1541. On its first leaf a figure paddles a canoe away from an island marked with a curl of water and a temple; a footprint-path begins, and does not stop for two centuries of pictured years. The island is Aztlán. The painting is the Codex Boturini, also called the Tira de la Peregrinación — the strip of the pilgrimage — and it is the foundational image of a homeland that the people who remembered it had, by the time it was drawn, already lost twice: once by leaving it, and once by losing the empire that leaving it had built.

Aztlán is the place the Mexica departed from. Every account of who they were begins there and moves away from it. The name is built from the Nahuatl aztatl, heron, with the locative -tlan: the place of herons, and by extension a place of whiteness, taken from the white plumage of the wading birds and from a remembered whiteness of the land itself. From Aztlán comes aztecatl, “person of Aztlán” — the word, plural aztecah, that nineteenth-century writers would generalize into “Aztec,” though the people called themselves Mexica after their god and their final city. The homeland sat somewhere to the north of the Valley of Mexico, described now as an island in a lake, now as a region, its exact location never fixed because it was never meant to be a coordinate. It was the point of origin a migrating people carries with them, behind them, the whole of the road.

The departure and the seven caves

The migration legend that the codices preserve is not a single tidy story but a family of them, drawn and annotated across several manuscripts — the Boturini strip, the related Codex Aubin, the Codex Azcatitlan, and the prose chronicles compiled from native sources by Spanish friars. Their common spine runs as follows. In the lake-land of Aztlán the Mexica lived among other Nahuatl-speaking peoples, subject and unremarkable, until their tutelary god commanded them to leave and promised them dominion at the end of the road. The god is Huitzilopochtli, the hummingbird of the south, a sun-and-war deity who in the migration accounts speaks through his priests, is carried as a bundle, and guides the people station by station toward a sign he alone will recognize.

Bound up with Aztlán in the sources is Chicomoztoc, “the place of the seven caves” — a womb-mountain pierced by seven hollows from which the Nahua peoples are said to have emerged. The seven caves give seven groups, the tlahtohcayotl of related tribes who would settle central Mexico: in the most common reckoning the Xochimilca, Tlahuica, Acolhua, Tlaxcalteca, Tepaneca, Chalca, and, last to depart, the Mexica. Some narratives keep Aztlán and Chicomoztoc as two distinct stages of one road — first the island left behind, then the cave-mountain passed through; others fuse them, as the Dominican chronicler Diego Durán does when he writes of a single ancestral country he calls Aztlan-Colhuacan-Chicomoztoc. The doubling is not confusion. It is the logic of an origin remembered as both a watery homeland and a generative emergence, a place one sailed from and a place one was born out of, held together because both are answers to the same question: before the city, where were we?

The road south is a road of stations, each a place-glyph strung along the painted path of footprints. The Mexica pause, plant, build a small altar to their god, observe the calendar-bundle ceremony that ties off each fifty-two-year cycle, and move on when Huitzilopochtli orders it. At Coatepec, the serpent hill near Tula, the most charged episode of the journey unfolds in the parallel mythic register: there Huitzilopochtli is born fully armed from his mother Coatlicue and destroys his sister Coyolxauhqui and the four hundred southern stars — a cosmogony of the sun’s daily victory mapped onto a waypoint of the migration. The people press on through the ruined Toltec world, sometimes welcomed, more often expelled, carrying the reputation of a harsh and dangerous god, until they reach the marshy islands of Lake Texcoco where no one else wants to live.

The sign and the city

There the promise is kept. On a small island Huitzilopochtli’s sign appears: an eagle settled on a nopal cactus growing from stone — in the fullest tellings, the eagle holds a serpent, an image that would travel five centuries forward onto the flag of the Mexican Republic. On that spot, by the reckoning the chronicles supply, the Mexica found Tenochtitlan in the year 1325. The Boturini strip carries its painted history from a starting date conventionally read as 1168 down to 1355, closing on the early settlement; the foundation it points toward becomes, within two centuries, the capital of an empire that holds the Valley of Mexico and reaches to both oceans.

The whole arc has a shape that the tradition itself insists on: a people of no account, leaving a place of origin under divine command, wandering, suffering, and arriving at greatness. Aztlán functions in this shape as the necessary before — the humble homeland whose abandonment is the precondition of the prophecy. The Mexica did not minimize their lowly beginnings; they made them the engine of their claim. To have come from Aztlán was to have been chosen to leave it.

That this homeland is a legend and not a documented place is the plain conclusion of the modern study of the sources. The migration narratives are post-classic and largely post-conquest in the form that survives; they encode dynastic charter, calendrical structure, and the political needs of the imperial Mexica far more legibly than they encode a retraceable route. Antiquarians and enthusiasts have proposed locations from the Mexican northwest — Nayarit, the Lake of Mexcaltitán — up into the present-day United States, and none commands scholarly assent. The homeland’s value was never geographic. A migration legend needs a starting point the way a story needs a first sentence; Aztlán is that sentence, and its lack of coordinates is not a defect in the legend but a feature of it.

The return that was sent for

The most revealing episode in the whole Aztlán corpus is the one in which the Mexica, at the height of their power, tried to go back. Durán’s Historia records it, and the Crónica mexicáyotl echoes it. The fifth ruler, Motecuhzoma Ilhuicamina — Moctezuma the Elder, who reigned roughly 1440 to 1469 — moved by his counselor Tlacaelel, resolved to find the ancestral land and the mother of the god, to learn whether she still lived and to send her gifts worthy of how far her people had come. He gathered some sixty sorcerers, loaded them with gold, jewels, feathers, and fine cloth, and sent them north.

The chroniclers describe the expedition not as a march but as a transformation: at Coatepec the magicians anointed themselves, became nahualli — shape-shifters, beasts and birds — and crossed into the ohuican tlalli, the perilous land that ordinary bodies cannot enter. They reached Aztlán. They found a hill in a lake, and an old guardian who took them up it, where they grew heavier and slower with every step while their guide moved lightly, because, he told them, the food of Aztlán had not corrupted them as the food of Mexico had. At the summit waited Coatlicue, aged and grieving, still keeping her son’s room as he had left it, still waiting for Huitzilopochtli to come home. She received the gifts, sent back a mantle and an austere word — that the greatness of Mexico was lent, not given, and would be reclaimed — and the messengers returned changed and diminished.

The episode is doctrine in narrative form. The homeland is reachable only by leaving the body and the world; arrival in it ages and burdens those grown rich on the road; the divine mother does not rejoice in the empire but warns it; and the gifts of the powerful capital cannot buy back the simplicity of the place it came from. Aztlán is, in this telling, the country one cannot return to as oneself — a homeland defined precisely by the impossibility of the homecoming it provokes. The Mexica imagined the journey back and imagined themselves unfit to complete it.

Aztlán reclaimed: the Chicano homeland

Four and a half centuries after the Boturini painter, Aztlán was claimed again, by people for whom the United States Southwest — the territory Mexico ceded under the Treaty of Guadalupe Hidalgo in 1848 — was both their inheritance and a land in which they were treated as strangers. At the First National Chicano Liberation Youth Conference, held in Denver in March 1969 and hosted by Rodolfo “Corky” Gonzales and his Crusade for Justice, some fifteen hundred young Mexican Americans adopted a manifesto that took the ancestral homeland as its name and its claim: El Plan Espiritual de Aztlán. Its preamble was a poem by Alurista (Alberto Baltazar Urista Heredia), read to the conference and adopted as the document’s opening; in it the assembled declared themselves, in the spirit of a people conscious of both their heritage and the invasion of their territories, the inhabitants and civilizers of the northern land of Aztlán from which their forefathers had come — and reclaimed it.

The geographic move is the heart of the reclamation. If the Mexica came south from a homeland in the north, then the north — the present-day American Southwest, the very land annexed in 1848 — is Aztlán. The migration legend is run in reverse: the lost origin is not behind the Mexica in space and time but underfoot, beneath El Paso and Los Angeles and Denver, an indigenous title older than the border that cut across it. From this the Plan drew a politics of Chicanismo — cultural nationalism, self-determination, “the bronze continent” and “the people of the sun” as terms of a shared identity — and gave its name to the student movement MEChA, the Movimiento Estudiantil Chicano de Aztlán. The “spiritual” in the title is exact: the Plan does not assert a literal lost civilization to be excavated. It claims a homeland as inheritance and identity, a symbolic territory that confers belonging and a moral right to the land one stands on.

This reception is, by intention and provenance, distinct from the esoteric lost-continent tradition. Aztlán did not pass through the séance room or the root-race cosmology. It descends from a documented indigenous migration legend with a colonial-era textual base in the Nahua codices and the friars’ chronicles, and it was reanimated in the twentieth century as a political and cultural symbol, not as a vanished super-civilization to be reconstructed. Where the broader genre of sunken and hidden homelands is treated in the reception history of lost-civilization claims, Aztlán sits at its edge rather than its center, and a recurring fringe etymology that would tie Aztlán to Atlantis — joining the names by sound — has no standing in either tradition: the Platonic island and the heron-place of the Nahua are unrelated origins, and the Aztlán claim does not rest on the connection.

The sources and their study

The Aztlán legend is known through two layers of record, and modern scholarship reads them against each other. The first is pictorial: the migration codices, of which the Codex Boturini is the most direct — a single black-line strip on amatl paper, painted within a generation of the conquest and now held at the Museo Nacional de Antropología in Mexico City, named for the eighteenth-century Italian antiquarian Lorenzo Boturini Benaduci, who assembled the collection it once belonged to. Its companions, the Codex Aubin and the Codex Azcatitlan, carry the same itinerary with variants. The standard art-historical treatment of the three is Angela Herren Rajagopalan’s Portraying the Aztec Past: The Codices Boturini, Azcatitlan, and Aubin (University of Texas Press, 2018), which reads the strip not as a transcript of events but as a constructed history serving the Mexica’s imperial self-image. The early facsimile and paleographic tradition runs through the nineteenth-century antiquarians; the museum issued a digital surrogate of the Boturini in 2015.

The second layer is the prose chronicle, compiled from native testimony and pictorial sources by Spanish religious in the sixteenth century. Fray Diego Durán’s Historia de las Indias de Nueva España e islas de Tierra Firme, finished about 1581, supplies the fullest narrative of the migration and the unique account of Motecuhzoma Ilhuicamina’s expedition to find Aztlán; it survives in the Doris Heyden English translation (The History of the Indies of New Spain, University of Oklahoma Press, 1994) and remains the indispensable source for the homeland’s lore. The Nahuatl-language Crónica mexicáyotl, associated with Hernando Alvarado Tezozómoc and the Chimalpahin annals, preserves the migration in the people’s own language. For the documentary and pictorial record as a whole, the Codex Boturini overview on Wikipedia and the museum’s 2015 digital surrogate are the working points of entry. The scholarly verdict across this literature is consistent: Aztlán is the charter-myth of a historical people, legible as ideology and calendar, not as a findable place — the seminal essay-collection on its modern afterlife being Rudolfo Anaya and Francisco Lomelí’s edited Aztlán: Essays on the Chicano Homeland (University of New Mexico Press, 1989).

The twentieth-century reclamation has its own archive. El Plan Espiritual de Aztlán is held in full in the ICAA Documents Project at the Museum of Fine Arts, Houston, the standard digital repository for primary documents of Latin American and Latino art and thought, where its 1969 text and provenance can be consulted directly.

Aztlán among the lost homelands

Set beside the other legendary homelands, Aztlán is the one most firmly anchored to a real people’s account of its own past. Atlantis begins as a philosophical parable and acquires its lost-race afterlife centuries later. Lemuria begins as a discarded scientific hypothesis and is reborn as occult doctrine. The Pacific Mu, the northern Hyperborea, the hidden kingdoms of Shambhala and Agartha — each is built from a different material and carries a different weight. Several of these were folded by Theosophy and by Helena Blavatsky into the architecture of the root races, the sequence of vanished continents staged as chapters in the spiritual evolution of humanity. Aztlán was not. It is not a root-race continent; it is the homeland of a historical people, recorded by that people and its descendants, contested and reclaimed as their own.

What sets Aztlán apart, in the end, is the structure of longing built into it from the first leaf of the Boturini strip. The other lost lands are places that sank, or hid, or were destroyed — gone, and mourned for their going. Aztlán was not destroyed. It was left — left on purpose, under a god’s order, as the founding act of a people. And so it remains, in the logic the legend gives it, a homeland one is always walking away from and always trying to find the way back to: sent for by an emperor whose magicians could reach it only by ceasing to be men, claimed again by a movement that located it under its own feet. The footprints on the painted strip lead in one direction. The whole tradition reads them in both.
