A remarkable manuscript documenting the history of the Mexica people has returned to Mexico after spending nearly two centuries outside the country, giving the public a rare opportunity to see an important record of Mesoamerican history.

The Azcatitlan Codex, created in the Valley of Mexico between the late 16th and early 17th centuries, is now being displayed at Mexico City’s National Museum of Anthropology. The manuscript had left Mexico in 1840 and is part of the collections of France’s National Library. It will remain on public display until December 6, 2026.

A Manuscript That Connects Two Writing Traditions

The Azcatitlan Codex is particularly valuable because it combines two different traditions of recording history.

Its pages use the Mesoamerican pictographic tradition together with elements of European writing. This combination reflects the cultural environment that developed after the arrival of the Spanish, when Indigenous methods of recording history continued while European forms of writing were introduced.

The manuscript contains 20 folios and is divided into three broad sections.

Together, they tell a long historical narrative beginning with the Mexica migration from Aztlan and continuing through the establishment of Mexico-Tenochtitlan, the succession of rulers, the arrival of the Spanish, the conquest and the subsequent evangelization.

More Than a Record of Kings

The codex provides information extending beyond the names of rulers.

Its illustrations and written elements preserve accounts of migration, political authority, historical events and changing cultural circumstances.

This makes the manuscript particularly useful for researchers studying how the Mexica understood and represented their own past.

Rather than presenting history solely through modern written descriptions, the codex offers a visual record in which symbols, images and written language work together.

A Journey That Began Centuries Ago

The story recorded in the manuscript begins with the Mexica migration from Aztlan.

The migration narrative is an important part of Mexica historical tradition and connects the community’s origins with its eventual settlement in the Valley of Mexico.

The codex then follows the development of Mexico-Tenochtitlan and records the city’s rulers and significant events associated with their reigns.

Its later sections document the arrival of the Spanish and the dramatic transformation that followed.

The Conquest Through an Indigenous Historical Lens

One of the reasons the Azcatitlan Codex is important to historians is that it preserves an Indigenous perspective on a period of profound political and cultural change.

The manuscript records the arrival of Spanish forces, the conquest and the subsequent process of evangelization.

This allows researchers to examine the transition from the pre-Hispanic world to colonial society through a document that combines Indigenous visual traditions with elements of European writing.

A Cultural Exchange Between Mexico and France

The manuscript’s return is also connected to a wider cultural exchange between Mexico and France.

The temporary transfer forms part of a programme marking 200 years of diplomatic relations between the two countries.

Under the arrangement, Mexico has temporarily received the Azcatitlan Codex, while the Codex Boturini is being sent to France for exhibition.

The exchange demonstrates how historical manuscripts can become part of modern cultural diplomacy.

A Wider Exhibition Around the Codex

Visitors are not seeing the manuscript in isolation.

The exhibition includes 25 archaeological and ethnographic objects connected with the production, preservation and cultural context of these documents.

It also includes facsimiles of nine pre-Hispanic and colonial-era manuscripts.

Among them are the Codex Bodley, Codex Boturini, Codex de la Cruz-Badiano and Codex Mendoza.

The exhibition is organized around six themes examining Indigenous manuscript traditions, their survival during the colonial period, the history of the Azcatitlan Codex and current approaches to its study.

How Ancient Documents Were Made

Some of the accompanying archaeological objects provide clues about the physical production of historical documents.

The exhibition includes stone tools used in preparing paper, along with other objects associated with Indigenous material culture.

These items help visitors understand that a manuscript was not simply a collection of written pages. Its creation depended on specialized materials, tools, artistic knowledge and traditions passed between generations.

Why the Codex Matters Today

The return of the manuscript has significance beyond its historical value.

For Indigenous communities, historical documents can represent connections with ancestral memory and cultural identity.

The Mexican government has described the initiative as involving cooperation between institutions as well as communities interested in preserving and reconnecting with Indigenous heritage.

The exhibition therefore brings together archaeology, history, art, anthropology and modern cultural diplomacy.

Preserving Knowledge Across Generations

The survival of the Azcatitlan Codex is remarkable considering the political and cultural changes that took place after its creation.

Manuscripts can deteriorate because of environmental conditions, handling, war, migration and changes in ownership.

Their preservation therefore requires specialized conservation and careful research.

The current exhibition also provides an opportunity for researchers and visitors to study the manuscript alongside related objects and other documentary traditions.

A Rare Opportunity for the Public

The temporary exhibition gives visitors in Mexico direct access to a manuscript that had been outside the country since the 19th century.

Its presence in Mexico also allows the document to be viewed within the cultural environment connected to the history it records.

The exhibition is scheduled to remain open at the National Museum of Anthropology until December 6, 2026, with free admission.

History as a Living Connection

The Azcatitlan Codex demonstrates how an ancient manuscript can connect different periods of history.

It preserves memories of migration and political change while also revealing how Indigenous traditions adapted to a new cultural environment.

Its temporary return to Mexico has consequently become more than a museum event. It represents an opportunity to examine how historical documents travel across borders, how cultures preserve memory and how international cooperation can bring important heritage closer to the communities connected with it.
