CORE_CORRECTION:
Mesoamerica is a plural interaction field, not a single civilisation and not a succession ladder.
Olmec → Maya → Toltec → Mexica is prohibited as a default genealogy.
Teotihuacan, Zapotec, Maya, Mixtec, Gulf Coast and western Mexican clocks overlap and recombine.
1521 is a major political fracture, not the end of Indigenous Mesoamerica.

30-LAYER CHRONOLOGY:

01 · Planetary inheritance | Deep time–late Pleistocene
TRANSFORMATION: Volcanic highlands, intermontane basins, tropical lowlands, karstic Yucatán, Pacific and Gulf coasts, major river systems and highly varied rainfall regimes create a dense mosaic of possibilities and hazards.
GUARDRAIL: Geography and climate constrain and enable; they do not predetermine a civilisation.

02 · Late Pleistocene settlement | before c. 10,000 BCE; earliest regional dates remain debated
TRANSFORMATION: Human populations occupy parts of Mexico and Central America by the terminal Pleistocene. Routes, population size and some proposed very early dates remain active archaeological questions.
GUARDRAIL: Early site dates are not modern ethnic identities and disputed chronologies remain disputed.

03 · Holocene plant-management worlds | c. 9000–4000 BCE
TRANSFORMATION: People intensify the management of diverse plants. Maize is domesticated from teosinte in southwestern Mexico over a long process; squash, beans, chilli, avocado and other foods enter changing cultivation systems at different times and places.
GUARDRAIL: A crop package is not born fully assembled, and domestication is not a single event.

04 · Villages, mobility and regional ritual | c. 4000–2000 BCE
TRANSFORMATION: Sedentary villages expand in some zones while mobility remains important elsewhere. Ceramic traditions, household economies and local ceremonial practices diversify.
GUARDRAIL: Village life does not automatically imply hierarchy, statehood or a single Mesoamerican identity.

05 · Early Formative interaction field | c. 2000–1200 BCE
TRANSFORMATION: Gulf Coast, Pacific, Oaxaca, central Mexican and Maya-area communities exchange obsidian, ceramics, symbols, crops and ritual practices while developing locally distinctive social forms.
GUARDRAIL: Similarity can reflect interaction, parallel development or shared conditions; it does not prove derivation.

06 · San Lorenzo and early Olmec florescence | c. 1400–1000 BCE
TRANSFORMATION: San Lorenzo becomes a major Gulf Coast centre with monumental earthworks, water management, elite display and colossal stone sculpture supported by long-distance material movement.
GUARDRAIL: ‘Olmec’ is an archaeological-historical label; it is not a proven single ethnic nation or the automatic source of every later Mesoamerican institution.

07 · La Venta, Tres Zapotes and plural Formative centres | c. 1000–400 BCE
TRANSFORMATION: La Venta and later Gulf Coast centres coexist with growing ceremonial and political systems elsewhere. Shared iconography and exchange widen, but multiple regions innovate at once.
GUARDRAIL: Replace the one-way ‘mother culture’ model with evidenced routes, local adaptation and independent development where appropriate.

08 · Oaxaca and Monte Albán | c. 500 BCE–850 CE
TRANSFORMATION: Monte Albán grows into a major Zapotec-centred hilltop capital with monumental planning, writing, calendrical records, water works, warfare and regional political reach.
GUARDRAIL: Zapotec language, archaeological material, polity and living Zapotec identities are related but not interchangeable object classes.

09 · Early Maya monumental landscapes | c. 1000 BCE–250 CE
TRANSFORMATION: Ceibal, Aguada Fénix, El Mirador and many other centres show that large communal constructions, public ritual landscapes and political differentiation arose early and through several pathways in the Maya region.
GUARDRAIL: Early Maya development is not simply downstream from Gulf Coast Olmec society.

10 · Teotihuacan urban takeoff | c. 100 BCE–250 CE
TRANSFORMATION: Population concentrates in the Basin of Mexico and Teotihuacan becomes a planned metropolis structured by the Avenue of the Dead, monumental pyramids, apartment compounds, craft production and regional exchange.
GUARDRAIL: Urban scale does not reveal a single known ethnicity or fully resolved constitutional form.

11 · Classic-period plural high civilisation | c. 250–600 CE
TRANSFORMATION: Teotihuacan, Monte Albán and numerous Maya dynastic polities flourish simultaneously. Writing, calendrics, court art, markets, intensive agriculture, reservoirs, causeways and craft specialisation operate in different combinations.
GUARDRAIL: Synchrony is not hierarchy; there is no single capital of Mesoamerica.

12 · Teotihuacan as Interface Processor | c. 200–550 CE
TRANSFORMATION: Oaxacan, Gulf Coast, Maya-linked and western Mexican populations are visible in Teotihuacan neighbourhoods. Trade, diplomacy, migration and political intervention connect the metropolis to distant regions, including the Maya lowlands.
GUARDRAIL: Foreign material at a site does not by itself prove conquest; relationship type must be specified.

13 · Maya dynastic networks and the 378 CE problem | 4th–6th centuries CE
TRANSFORMATION: Maya inscriptions document dynastic competition and alliance. The arrival of Sihyaj K’ahk’ at Tikal in 378 CE coincides with strong central Mexican/Teotihuacan-linked imagery and political change.
GUARDRAIL: Direct Teotihuacan conquest, sponsored intervention and elite emulation remain distinct hypotheses where evidence does not decide among them.

14 · Teotihuacan fracture and Epiclassic recomposition | c. 550–900 CE
TRANSFORMATION: Fire, internal conflict and demographic decline transform Teotihuacan. Xochicalco, Cacaxtla, Cholula, El Tajín and other centres participate in a more fragmented but still highly connected political-commercial field.
GUARDRAIL: Urban decline is not regional civilisational disappearance.

15 · Late Classic Maya florescence | c. 600–800 CE
TRANSFORMATION: Tikal, Calakmul, Palenque, Copán, Caracol, Yaxchilán and many other polities build dense court networks and monumental histories while households sustain intensive farming, reservoirs, terraces, craft systems and markets.
GUARDRAIL: ‘The Maya’ were never one empire; polity-level agency must be resolved before civilisation-scale language is used.

16 · Classic Maya political-demographic transformations | c. 750–950 CE
TRANSFORMATION: Many southern and central lowland royal centres lose population and dynastic monument production amid warfare, political fragmentation, environmental stress and shifting exchange. Northern and coastal Maya systems continue and reorganise.
GUARDRAIL: Use ‘collapse’ only for specified institutions, cities or demographic fields; Maya peoples did not disappear.

17 · Chichén Itzá and northern Maya recomposition | c. 800–1100 CE
TRANSFORMATION: Chichén Itzá becomes a major northern centre with far-reaching exchange, monumental architecture and political-religious forms that connect Yucatán to wider Mesoamerican networks.
GUARDRAIL: Architectural similarity with Tula does not by itself establish a simple one-direction Toltec conquest.

18 · Tula and Toltec memory | c. 800–1150 CE
TRANSFORMATION: Tollan-Xicocotitlan (Tula) becomes an influential central Mexican city associated with military orders, long-distance exchange, craft production and later prestige memories of ‘Toltec’ civilisation.
GUARDRAIL: A territorially uniform ‘Toltec Empire’ is not treated as established fact; archaeology and later political memory are stored on separate evidence clocks.

19 · Mixtec and Zapotec Postclassic worlds | c. 900–1521 CE
TRANSFORMATION: Oaxaca contains numerous dynastic centres, alliances and rivalries. Mixtec screenfold manuscripts preserve named rulers, marriages, places and conquests; Zapotec and Mixtec lineages interact, including at reused sacred sites such as Monte Albán.
GUARDRAIL: ‘Mixtec’ and ‘Zapotec’ describe living peoples and languages as well as historical materials; do not collapse all periods into one identity.

20 · Postclassic market and corridor intensification | c. 1000–1300 CE
TRANSFORMATION: Coastal trade, obsidian, salt, cacao, cotton, metals, feathers and ceramics move through expanding market and pilgrimage networks linking Yucatán, Gulf, Oaxaca, central Mexico and Central American interfaces.
GUARDRAIL: Exchange reach is not territorial sovereignty.

21 · Mayapán, Cholula and regional political plurality | c. 1200–1450 CE
TRANSFORMATION: Mayapán becomes a major political centre in Yucatán while Cholula, Tlaxcala, Mixteca kingdoms and many other polities sustain distinct institutions, ritual authorities and commercial circuits.
GUARDRAIL: The Late Postclassic is not an Aztec waiting room.

22 · Mexica settlement and Basin of Mexico competition | c. 1200–1428 CE
TRANSFORMATION: Nahua-speaking groups and older Basin polities compete and ally. Mexica foundation traditions place Tenochtitlan in the 14th century; the city grows within the lake system under changing tributary relationships.
GUARDRAIL: Foundation narratives are historical memory with political and sacred functions, not automatically literal cartography.

23 · Mexica-led Triple Alliance | 1428–1519 CE
TRANSFORMATION: Tenochtitlan, Texcoco and Tlacopan form the Triple Alliance. Tributary conquest, markets, causeways, chinampa systems, aqueducts, military organisation and merchant networks support a powerful but uneven imperial configuration.
GUARDRAIL: ‘Aztec Empire’ is useful shorthand only if the Triple Alliance structure, tributary variation and non-Mexica agency remain visible.

24 · Purépecha/Tarascan state | c. 1300–1522 CE
TRANSFORMATION: A powerful state centred on the Lake Pátzcuaro basin and later Tzintzuntzan consolidates much of Michoacán. Bureaucratic administration, metallurgy, specialised production and a fortified eastern frontier check Mexica expansion.
GUARDRAIL: ‘Tarascan’ is a colonial/historical exonym; Purépecha is preferred for living people, while ancient polity, language and identity remain separately typed.

25 · 1519–1521: invasion, alliances and fall of Tenochtitlan | 1519–1521 CE
TRANSFORMATION: Hernán Cortés’ expedition enters a politically divided Mesoamerican field. Tlaxcalan and other Indigenous allies are decisive in the campaign; siege, warfare, factional politics and smallpox contribute to Tenochtitlan’s defeat in 1521.
GUARDRAIL: Spanish victory was not achieved by Europeans acting alone, and the fall of one imperial capital was not the end of Indigenous Mesoamerica.

26 · Conquest continues | 1520s–1697 CE
TRANSFORMATION: Spanish, allied Indigenous and successor colonial forces extend control unevenly across Oaxaca, Michoacán, Guatemala and Yucatán. Some Maya polities remain autonomous for generations; the Itza centre of Nojpetén falls only in 1697.
GUARDRAIL: Conquest is a regional sequence, not a single date.

27 · Colonial recombination, epidemic and survival | 16th–18th centuries
TRANSFORMATION: Missionisation, tribute, forced labour, congregación, new towns, livestock, Old World crops, legal institutions and epidemic disease transform society. Indigenous nobles, councils, communities, languages, manuscripts and land claims persist and adapt.
GUARDRAIL: Demographic catastrophe is not cultural extinction. Pathogen findings at specific cemeteries must not be promoted into one universal cause for every epidemic.

28 · Independence, liberal states and Indigenous struggles | 19th century–1910
TRANSFORMATION: Spanish imperial rule ends, but land, citizenship, taxation and labour regimes continue to reshape Indigenous communities. Liberal reforms, hacienda expansion, local republics, rebellion and the Caste War of Yucatán reveal highly uneven state incorporation.
GUARDRAIL: Independent nation-state ≠ completed decolonisation or equal receiver outcome.

29 · Revolution, archaeology and national indigenismo | 1910–late 20th century
TRANSFORMATION: Revolutionary Mexico, land reform, public archaeology, museums and indigenismo recast pre-Hispanic civilisation as national heritage. At the same time, living Indigenous peoples face assimilation pressures, language loss, inequality and struggles over land and political recognition.
GUARDRAIL: Monumental heritage ≠ living Indigenous authority; ancient prestige cannot substitute for present rights.

30 · Living Mesoamerica | 1994–9 August 2026
TRANSFORMATION: Nahua, Maya, Zapotec, Mixtec/Tu’un Savi, Purépecha and many other peoples remain living communities across modern states. Language revitalisation, community governance, archaeology, heritage protection, land defence and consultation rights operate alongside migration, tourism, development pressure and digital change.
GUARDRAIL: Mesoamerica is a historical-analytical coordinate, not a dead civilisation and not a single modern political identity.

INTERFACE PROCESSORS:

San Lorenzo / La Venta: Formative Gulf Coast exchange and ritual-political innovation
Monte Albán: Oaxaca highland political, writing and exchange interface
Teotihuacan: metropolitan migration, craft, diplomacy and interregional exchange processor
Chichén Itzá: northern Maya and circum-peninsular exchange processor
Tula: Early Postclassic central Mexican political-memory and exchange node
Cholula: pilgrimage, market and multi-polity continuity node
Tenochtitlan–Tlatelolco: lake-city tribute, market, hydraulic and imperial processor
Tzintzuntzan: western Mexican bureaucratic, metallurgical and frontier processor

CAPABILITY / DEPENDENCY / COST:

CAPABILITY: maize-intensive food systems
DEPENDENCY: water, labour, seed diversity, soils, storage
CARRIED_COST: crop risk, labour burden, land pressure in some contexts
CAPABILITY: monumental urbanism
DEPENDENCY: food surplus, labour coordination, materials, water
CARRIED_COST: elite extraction, maintenance load, ecological pressure can be high and uneven
CAPABILITY: long-distance exchange
DEPENDENCY: routes, security, merchant institutions, political permission
CARRIED_COST: dependency on corridor stability and unequal capture of value
CAPABILITY: writing/calendar systems
DEPENDENCY: specialists, media, institutions, transmission
CARRIED_COST: survivorship bias when archives are elite, destroyed or perishable
CAPABILITY: tributary empire
DEPENDENCY: military force, allies, tribute accounting, transport
CARRIED_COST: burden exported to subject communities; rebellion risk
CAPABILITY: heritage economy
DEPENDENCY: conservation, tourism, state/community governance
CARRIED_COST: commodification or exclusion if living communities do not receive authority or benefit

RECEIVER / NOBODY:

farm households whose labour sustained cities but rarely dominates monumental records
women, children, migrants, captives and servants underrepresented in elite inscriptions
communities outside major capitals
tributary populations carrying imperial extraction
epidemic victims and displaced communities
living Indigenous peoples whose heritage is represented without equivalent authority
non-human ecosystems carrying returned land, water and extraction costs
future people inheriting language loss, site damage, pollution or successful repair

FRACTURE / REPAIR:

Teotihuacan fracture -> Epiclassic political and market recomposition
Classic Maya dynastic decline -> population redistribution and Postclassic northern/coastal continuity
imperial conquest -> colonial community, language and legal adaptation
language shift -> community-led revitalisation, schooling, media and institutional use
archaeological extraction -> provenance, conservation, community participation and return of interpretive authority

FUTURE FLOOR:
EQUATION: Current Regional Floor + Repair + Regeneration + Conservation + Knowledge Transfer + Shock Absorption – Depletion – Pollution – Extinction – Climate Damage – Debt Transfer – War Damage – Natural Shock Loss
WIDENING ROUTES:

Indigenous language intergenerational transmission
community authority in heritage governance
archaeological conservation with open provenance
watershed and soil restoration
rights-respecting development consultation
cross-border Maya and Indigenous research partnerships
digital archives under appropriate community governance
BURNING ROUTES:
language loss
site looting and illicit trade
water depletion
unplanned tourism pressure
urban encroachment
violence and displacement
climate-intensified drought and heat
heritage narratives that erase living peoples

BOUNDED AI INSTRUCTION:

Resolve exact place, period, entity type and evidence class before synthesis.
Separate archaeological assemblage, language, ancestry, polity, ethnonym and living identity.
Do not infer direct transmission from synchrony or similarity; require route, carrier, mechanism, direction and interval.
Treat Olmec mother-culture, Toltec empire and singular Maya-collapse claims as hypotheses requiring scoped evidence.
Distinguish monument/elite archives from household and Receiver evidence.
For conquest, resolve Spanish, Indigenous-allied and rival-polity agency separately.
Do not treat living Indigenous communities as remnants of vanished civilisations.
Retrieve planetary inheritance but avoid environmental determinism.
Name returned ecological/social costs and Nobody positions.
Reverify all live policy, language, heritage and demographic claims after retrieval freeze.

“id”: “08”,
“label”: “Oaxaca and Monte Albán”,
“range”: “c. 500 BCE–850 CE”,
“transformation”: “Monte Albán grows into a major Zapotec-centred hilltop capital with monumental planning, writing, calendrical records, water works, warfare and regional political reach.”,
“guardrail”: “Zapotec language, archaeological material, polity and living Zapotec identities are related but not interchangeable object classes.”
},
{
“id”: “09”,
“label”: “Early Maya monumental landscapes”,
“range”: “c. 1000 BCE–250 CE”,
“transformation”: “Ceibal, Aguada Fénix, El Mirador and many other centres show that large communal constructions, public ritual landscapes and political differentiation arose early and through several pathways in the Maya region.”,
“guardrail”: “Early Maya development is not simply downstream from Gulf Coast Olmec society.”
},
{
“id”: “10”,
“label”: “Teotihuacan urban takeoff”,
“range”: “c. 100 BCE–250 CE”,
“transformation”: “Population concentrates in the Basin of Mexico and Teotihuacan becomes a planned metropolis structured by the Avenue of the Dead, monumental pyramids, apartment compounds, craft production and regional exchange.”,
“guardrail”: “Urban scale does not reveal a single known ethnicity or fully resolved constitutional form.”
},
{
“id”: “11”,
“label”: “Classic-period plural high civilisation”,
“range”: “c. 250–600 CE”,
“transformation”: “Teotihuacan, Monte Albán and numerous Maya dynastic polities flourish simultaneously. Writing, calendrics, court art, markets, intensive agriculture, reservoirs, causeways and craft specialisation operate in different combinations.”,
“guardrail”: “Synchrony is not hierarchy; there is no single capital of Mesoamerica.”
},
{
“id”: “12”,
“label”: “Teotihuacan as Interface Processor”,
“range”: “c. 200–550 CE”,
“transformation”: “Oaxacan, Gulf Coast, Maya-linked and western Mexican populations are visible in Teotihuacan neighbourhoods. Trade, diplomacy, migration and political intervention connect the metropolis to distant regions, including the Maya lowlands.”,
“guardrail”: “Foreign material at a site does not by itself prove conquest; relationship type must be specified.”
},
{
“id”: “13”,
“label”: “Maya dynastic networks and the 378 CE problem”,
“range”: “4th–6th centuries CE”,
“transformation”: “Maya inscriptions document dynastic competition and alliance. The arrival of Sihyaj K’ahk’ at Tikal in 378 CE coincides with strong central Mexican/Teotihuacan-linked imagery and political change.”,
“guardrail”: “Direct Teotihuacan conquest, sponsored intervention and elite emulation remain distinct hypotheses where evidence does not decide among them.”
},
{
“id”: “14”,
“label”: “Teotihuacan fracture and Epiclassic recomposition”,
“range”: “c. 550–900 CE”,
“transformation”: “Fire, internal conflict and demographic decline transform Teotihuacan. Xochicalco, Cacaxtla, Cholula, El Tajín and other centres participate in a more fragmented but still highly connected political-commercial field.”,
“guardrail”: “Urban decline is not regional civilisational disappearance.”
},
{
“id”: “15”,
“label”: “Late Classic Maya florescence”,
“range”: “c. 600–800 CE”,
“transformation”: “Tikal, Calakmul, Palenque, Copán, Caracol, Yaxchilán and many other polities build dense court networks and monumental histories while households sustain intensive farming, reservoirs, terraces, craft systems and markets.”,
“guardrail”: “‘The Maya’ were never one empire; polity-level agency must be resolved before civilisation-scale language is used.”
},
{
“id”: “16”,
“label”: “Classic Maya political-demographic transformations”,
“range”: “c. 750–950 CE”,
“transformation”: “Many southern and central lowland royal centres lose population and dynastic monument production amid warfare, political fragmentation, environmental stress and shifting exchange. Northern and coastal Maya systems continue and reorganise.”,
“guardrail”: “Use ‘collapse’ only for specified institutions, cities or demographic fields; Maya peoples did not disappear.”
},
{
“id”: “17”,
“label”: “Chichén Itzá and northern Maya recomposition”,
“range”: “c. 800–1100 CE”,
“transformation”: “Chichén Itzá becomes a major northern centre with far-reaching exchange, monumental architecture and political-religious forms that connect Yucatán to wider Mesoamerican networks.”,
“guardrail”: “Architectural similarity with Tula does not by itself establish a simple one-direction Toltec conquest.”
},
{
“id”: “18”,
“label”: “Tula and Toltec memory”,
“range”: “c. 800–1150 CE”,
“transformation”: “Tollan-Xicocotitlan (Tula) becomes an influential central Mexican city associated with military orders, long-distance exchange, craft production and later prestige memories of ‘Toltec’ civilisation.”,
“guardrail”: “A territorially uniform ‘Toltec Empire’ is not treated as established fact; archaeology and later political memory are stored on separate evidence clocks.”
},
{
“id”: “19”,
“label”: “Mixtec and Zapotec Postclassic worlds”,
“range”: “c. 900–1521 CE”,
“transformation”: “Oaxaca contains numerous dynastic centres, alliances and rivalries. Mixtec screenfold manuscripts preserve named rulers, marriages, places and conquests; Zapotec and Mixtec lineages interact, including at reused sacred sites such as Monte Albán.”,
“guardrail”: “‘Mixtec’ and ‘Zapotec’ describe living peoples and languages as well as historical materials; do not collapse all periods into one identity.”
},
{
“id”: “20”,
“label”: “Postclassic market and corridor intensification”,
“range”: “c. 1000–1300 CE”,
“transformation”: “Coastal trade, obsidian, salt, cacao, cotton, metals, feathers and ceramics move through expanding market and pilgrimage networks linking Yucatán, Gulf, Oaxaca, central Mexico and Central American interfaces.”,
“guardrail”: “Exchange reach is not territorial sovereignty.”
},
{
“id”: “21”,
“label”: “Mayapán, Cholula and regional political plurality”,
“range”: “c. 1200–1450 CE”,
“transformation”: “Mayapán becomes a major political centre in Yucatán while Cholula, Tlaxcala, Mixteca kingdoms and many other polities sustain distinct institutions, ritual authorities and commercial circuits.”,
“guardrail”: “The Late Postclassic is not an Aztec waiting room.”
},
{
“id”: “22”,
“label”: “Mexica settlement and Basin of Mexico competition”,
“range”: “c. 1200–1428 CE”,
“transformation”: “Nahua-speaking groups and older Basin polities compete and ally. Mexica foundation traditions place Tenochtitlan in the 14th century; the city grows within the lake system under changing tributary relationships.”,
“guardrail”: “Foundation narratives are historical memory with political and sacred functions, not automatically literal cartography.”
},
{
“id”: “23”,
“label”: “Mexica-led Triple Alliance”,
“range”: “1428–1519 CE”,
“transformation”: “Tenochtitlan, Texcoco and Tlacopan form the Triple Alliance. Tributary conquest, markets, causeways, chinampa systems, aqueducts, military organisation and merchant networks support a powerful but uneven imperial configuration.”,
“guardrail”: “‘Aztec Empire’ is useful shorthand only if the Triple Alliance structure, tributary variation and non-Mexica agency remain visible.”
},
{
“id”: “24”,
“label”: “Purépecha/Tarascan state”,
“range”: “c. 1300–1522 CE”,
“transformation”: “A powerful state centred on the Lake Pátzcuaro basin and later Tzintzuntzan consolidates much of Michoacán. Bureaucratic administration, metallurgy, specialised production and a fortified eastern frontier check Mexica expansion.”,
“guardrail”: “‘Tarascan’ is a colonial/historical exonym; Purépecha is preferred for living people, while ancient polity, language and identity remain separately typed.”
},
{
“id”: “25”,
“label”: “1519–1521: invasion, alliances and fall of Tenochtitlan”,
“range”: “1519–1521 CE”,
“transformation”: “Hernán Cortés’ expedition enters a politically divided Mesoamerican field. Tlaxcalan and other Indigenous allies are decisive in the campaign; siege, warfare, factional politics and smallpox contribute to Tenochtitlan’s defeat in 1521.”,
“guardrail”: “Spanish victory was not achieved by Europeans acting alone, and the fall of one imperial capital was not the end of Indigenous Mesoamerica.”
},
{
“id”: “26”,
“label”: “Conquest continues”,
“range”: “1520s–1697 CE”,
“transformation”: “Spanish, allied Indigenous and successor colonial forces extend control unevenly across Oaxaca, Michoacán, Guatemala and Yucatán. Some Maya polities remain autonomous for generations; the Itza centre of Nojpetén falls only in 1697.”,
“guardrail”: “Conquest is a regional sequence, not a single date.”
},
{
“id”: “27”,
“label”: “Colonial recombination, epidemic and survival”,
“range”: “16th–18th centuries”,
“transformation”: “Missionisation, tribute, forced labour, congregación, new towns, livestock, Old World crops, legal institutions and epidemic disease transform society. Indigenous nobles, councils, communities, languages, manuscripts and land claims persist and adapt.”,
“guardrail”: “Demographic catastrophe is not cultural extinction. Pathogen findings at specific cemeteries must not be promoted into one universal cause for every epidemic.”
},
{
“id”: “28”,
“label”: “Independence, liberal states and Indigenous struggles”,
“range”: “19th century–1910”,
“transformation”: “Spanish imperial rule ends, but land, citizenship, taxation and labour regimes continue to reshape Indigenous communities. Liberal reforms, hacienda expansion, local republics, rebellion and the Caste War of Yucatán reveal highly uneven state incorporation.”,
“guardrail”: “Independent nation-state ≠ completed decolonisation or equal receiver outcome.”
},
{
“id”: “29”,
“label”: “Revolution, archaeology and national indigenismo”,
“range”: “1910–late 20th century”,
“transformation”: “Revolutionary Mexico, land reform, public archaeology, museums and indigenismo recast pre-Hispanic civilisation as national heritage. At the same time, living Indigenous peoples face assimilation pressures, language loss, inequality and struggles over land and political recognition.”,
“guardrail”: “Monumental heritage ≠ living Indigenous authority; ancient prestige cannot substitute for present rights.”
},
{
“id”: “30”,
“label”: “Living Mesoamerica”,
“range”: “1994–9 August 2026”,
“transformation”: “Nahua, Maya, Zapotec, Mixtec/Tu’un Savi, Purépecha and many other peoples remain living communities across modern states. Language revitalisation, community governance, archaeology, heritage protection, land defence and consultation rights operate alongside migration, tourism, development pressure and digital change.”,
“guardrail”: “Mesoamerica is a historical-analytical coordinate, not a dead civilisation and not a single modern political identity.”
