Mexica (Aztec)

Status: Researched draft — cultural review pending

How to read this entry: Documented fact = inscriptional / codical, archaeological or published scholarly evidence (Sources). Tradition — the people's own account = Mexica/Nahua accounts as recorded in Nahua-authored and Nahua-informed sources, labelled as such. Debated / Claim = disputed point. No ceremonial instructions are given. Terminology: "Mexica" names the people of Mexico-Tenochtitlan; "Aztec" is a later umbrella term in scholarly and popular use (Lockhart, 1992, The Nahuas After the Conquest, Stanford University Press; Smith, 2003, The Aztecs, 2nd ed., Blackwell). The Mexica were one Nahua people among many; Nahua peoples are living peoples in Mexico today.

Language

• Family. Nahuatl belongs to the Uto-Aztecan family, Nahuan branch (Campbell & Langacker, 1978, and standard classification in Mithun's successors / INALI, 2008, Catálogo de las lenguas indígenas nacionales, Mexico). Classical Nahuatl was the language of Mexica government and much record-keeping.
• Status today. Mexico's INEGI 2020 census counts Nahuatl speakers in well over a million — Nahuatl is Mexico's most widely spoken Indigenous language — across many regional varieties, several of them endangered (INALI, 2008; INEGI, 2020). Exact totals by variety differ by census instrument; no merged figure beyond "over a million (2020 census, all varieties)" is asserted.
• Writing. Modern Nahuatl is written in Latin orthographies that vary by region and institution (INALI standardisation efforts, n.d.).

Traditions

• The Triple Alliance (1428). Documented fact: Tenochtitlan, Texcoco and Tlacopan formed the alliance that built the tribute empire conventionally called "Aztec," after defeating Azcapotzalco (Berdan et al., 1996, Aztec Imperial Strategies, Dumbarton Oaks; Smith, 2003). It was an alliance of city-states (altepetl), not a unitary nation-state.
• Tradition — the people's own account: Mexica migration from Aztlan and the founding of Tenochtitlan in 1325 (the date given in Mexica historical tradition as recorded in post-invasion annals; the founding date is traditional, not independently verified) — presented as Mexica account (Chimalpahin and the Crónica Mexicáyotl tradition, in Lockhart's translations / Schroeder, 1991).
• Calendrics. Two interlocking counts are documented across Mesoamerica and in Mexica sources: the 260-day tonalpohualli and the 365-day xiuhpohualli, combining in a 52-year cycle (Smith, 2003; Museo Nacional de Antropología, Sun Stone interpretation, via Google Arts & Culture). See Writings for the Sun Stone correction.
• Ceremonial content, including sacrificial rites documented extensively in colonial sources and archaeology (Templo Mayor offerings), is not described instructionally here; its scale and interpretation remain subjects of scholarly debate, and popular tallies of victims derived from colonial chroniclers are claims requiring caution, not settled counts (Hassig, 1988, Aztec Warfare; Graulich debates surveyed in Smith, 2003).

Treaties — Stated Honestly

As with the Maya, there is no Mexica treaty series with European states to list, and none is invented here. Documented instead: (1) inter-altepetl alliances and tribute arrangements within Mesoamerica (Berdan et al., 1996); (2) the 1519–1521 war and alliances — notably the Tlaxcalan alliance with Cortés, an alliance of Indigenous polities in a Mesoamerican war, documented from both Nahua and Spanish sources (Restall, 2003, Seven Myths of the Spanish Conquest, Oxford University Press); and (3) colonial legal instruments (encomienda, congregación) imposed after Tenochtitlan's fall on 13 August 1521 — a documented date (Díaz del Castillo; Cortés letters; Lockhart, 1992). Modern Nahua rights rest in Mexican constitutional and agrarian law, not historic treaties — stated plainly so the site does not fabricate an equivalence.

Writings

• Script. Mexica writing combined logographic and phonetic (rebus) elements in painted books and inscriptions — a system whose phonetic extent was long understated and is now documented in detail (Lacadena, 2008, "Regional Scribal Traditions," in The Aztec World; Whittaker, 2021, Aztec Pictography, University of Texas Press — Whittaker's fuller decipherment claims are a scholarly position, flagged as such).
• Codices. Pre-invasion and early colonial screenfolds and manuscripts include the Codex Borgia group (ritual/divinatory), and post-invasion Nahua-authored works: the Florentine Codex (Bernardino de Sahagún with Nahua scholars, completed c. 1577; held at the Laurentian Library, Florence — hence its name), the Codex Mendoza (c. 1542; Bodleian Library, Oxford) and community annals and títulos (Florentine Codex, General History, Anderson & Dibble translation, 1950–82, University of Utah Press).
• The Sun Stone is not a working calendar. The Museo Nacional de Antropología's own interpretation, via Google Arts & Culture: the so-called "Aztec Calendar" / Piedra del Sol, unearthed 17 December 1790 in Mexico City's Plaza Mayor, "symbolizes the conception of time for the Mexicas, despite not actually working as a calendar"; its centre shows the Fifth Sun (Nahui Olin) with the face identified by the museum with Tonatiuh, ringed by the signs of the four previous suns and the 20 day-signs (Museo Nacional de Antropología, n.d.). The central face's identity is debated among scholars — flagged.

Crafts, Arts, Skills

• Chinampas. Documented: raised lake-bed plots built in the shallow lakes of the Basin of Mexico — staked rectangles layered with mud and vegetation, producing multiple harvests a year and supporting Tenochtitlan's population; chinampa agriculture survives at Xochimilco, a UNESCO World Heritage property (inscribed 1987 with the Historic Centre of Mexico City) (UNESCO World Heritage Centre, property 412; Coe, 1964, "The Chinampas of Mexico," Scientific American). Note: chinampas are fixed plots, not "floating gardens" — the popular phrase is a misnomer to correct on the site.
• Tenochtitlan engineering. Causeways, aqueducts (Chapultepec), dikes separating fresh and brackish lake water, and the Templo Mayor precinct are documented archaeologically (Matos Moctezuma, 1988, The Great Temple of the Aztecs, Thames & Hudson).
• Obsidian and featherwork. Prismatic obsidian blade technology and amanteca feather mosaics are documented crafts (Smith, 2003; Museo Nacional de Antropología collections).
• Medicine / plants — historical record only. The Florentine Codex, Book 11, and the Badianus Manuscript (1552, Nahua herbal by Martín de la Cruz, translated by Juan Badiano; held at INAH after its 1990 return to Mexico) record historical plant uses (Emmart, 1940, The Badianus Manuscript, Johns Hopkins). Caution: historical record is not proof of clinical effectiveness; no dosages, preparations or treatment instructions are given.

Weakest-sourced points in this entry (flagged): (1) Tenochtitlan's 1325 founding date — traditional, not independently verified; (2) extent of phoneticism / Whittaker's decipherment claims — active scholarly debate; (3) colonial chroniclers' sacrifice tallies — not used as counts here.
