Point markers show approximate public towns or distant institutional orientation only, sometimes far from the archaeological context. They never define territorial, ethnic, linguistic, cultural, political, religious, sovereignty, trade-route, hunting, grazing, farming, fishing or water-rights boundaries. They do not pinpoint burials, ancestral remains, sacred places, private land or vulnerable deposits; grant no access, digging, collecting, hunting or travel permission; and do not decide ownership or current safety. Shared orientation points are intentional, not multiple sites at one coordinate.
Reviewed place and institutional names are retained; no otherwise unknown ancient self-designation is invented.
The heritage record links Ayutthaya's location with river connections toward the sea; a map point cannot reconstruct all routes or their control. The evaluation places the capital's foundation around 1350. Later temples, diplomacy and commerce require their own dates rather than an undifferentiated golden age.
Riverine court and urban political networksApproximately 1350–1500 CE in this profile; later global connections and 1767 destruction separately datedCity landscape, monumental remains and attributed heritage evaluation
Reference town or distant institutional context
Bangkok, Thailand, distant public-city orientation: approximate public-town or distant institutional orientation, not an excavation, burial, sacred-site, cave-entrance, private compound, underwater or vulnerable-deposit location; never a territorial, ethnic, linguistic, cultural, political, religious, sovereignty, fishing, water-rights or route boundary. The orientation may be far from the archaeological context. No access, collecting, ritual or travel permission is implied.

The heritage record places Bagan's major building period in the eleventh–thirteenth centuries and treats it as a landscape, not merely a collection of isolated temples. The evaluation discusses merit-making and patronage alongside the material requirements of monuments; visible elite donations do not recover all household work or labor status.
Court, religious institutions, and urban landscapeMain eleventh–thirteenth centuries CE; subsequent worship and heritage history distinguishedMonuments, inscriptions, settlement landscape and conservation assessment
Reference town or distant institutional context
Mandalay, Myanmar, distant public-city orientation: approximate public-town or distant institutional orientation, not an excavation, burial, sacred-site, cave-entrance, private compound, underwater or vulnerable-deposit location; never a territorial, ethnic, linguistic, cultural, political, religious, sovereignty, fishing, water-rights or route boundary.

The dating study combines stratigraphic order with radiocarbon measurements to investigate transitions among Neolithic, bronze-using and iron-using phases. Higham's later discussion situates the site within continuing arguments about dating, farming and social change rather than treating chronology as a settled regional template.
Prehistoric settlement and chronological researchApproximately second millennium BCE–early first millennium CE; modeled phases and modern research distinguishedStratigraphy, radiocarbon models, excavated objects and community-linked research
Reference town or distant institutional context
Nakhon Ratchasima, Thailand: approximate public-town or distant institutional orientation, not an excavation, burial, sacred-site, cave-entrance, private compound, underwater or vulnerable-deposit location; never a territorial, ethnic, linguistic, cultural, political, religious, sovereignty, fishing, water-rights or route boundary.

The heritage account interprets the citadel's arrangement through contemporary landscape principles; this is a planning interpretation, not a religious census. The evaluation dates construction to 1397 and distinguishes the short Hồ ruling period from the longer history of occupation and later reception.
Short-lived court center and monumental constructionMain 1397–early fifteenth century CE; later use and conservation distinguishedStone fortifications, spatial planning, archaeology and attributed heritage evaluation

Thanh Hóa, Viet Nam, distant public-city orientation: approximate public-town or distant institutional orientation, not an excavation, burial, sacred-site, cave-entrance, private compound, underwater or vulnerable-deposit location; never a territorial, ethnic, linguistic, cultural, political, religious, sovereignty, fishing, water-rights or route boundary. The orientation may be far from the archaeological context. No access, collecting, ritual or travel permission is implied.

The heritage account includes Kamphaeng Phet alongside Sukhothai and Si Satchanalai rather than collapsing their histories into a single city. The evaluation discusses fortification and religious architecture; construction reflects organized work but does not establish that every worker had the same legal status.
Medieval fortified town and religious landscapeMain fourteenth–fifteenth centuries CE; earlier proposals and later reception separatedTown layout, walls, building materials and heritage evaluation

The heritage account associates Koh Ker's principal court role with 928–944 CE, distinguishing it from Angkor rather than duplicating Angkor's history. The evaluation examines construction and urban infrastructure; monumental investment required material procurement and labor not fully represented by royal records.
Short-lived court center and urban landscapeMain tenth century CE; later landscape and modern heritage history distinguishedBuildings, inscriptions, water infrastructure and archaeological heritage evaluation

The tentative submission describes monuments mainly of the fifteenth–sixteenth centuries; this profile concentrates on the earlier portion and labels later fabric explicitly. The guide examines fortification and water management in a landscape connected to the coast. Such infrastructure does not establish that every resident belonged to one religion or ethnicity.
Late medieval court and water landscapeMain fifteenth century CE, beginning with the attributed 1430 foundation; later monuments separately identifiedArchaeological landscape, retrospective historical synthesis and attributed heritage submissions

The museum essay associates Nakhon Pathom with Dvaravati-period patronage and sculpture, while its broad language labels need evidence-specific use. Khunsong's excavation study reports terracotta roof tiles from investigations in 2009–2010, revising an earlier absence of such finds at Nakhon Pathom.
Early urban and religious archaeologyMain sixth–eleventh centuries CE; nineteenth-century rebuilding and modern excavation distinguishedReligious sculpture, inscriptions, excavated roof tiles and rebuilding history

The 2022 study adds dated rice grains to an earlier charcoal chronology, allowing the timing of Iron Age phases to be reconsidered. Higham's regional household study warns that settlement plans and domestic activities are much less visible than selected mortuary evidence; neighboring Non Ban Jak is a comparison, not the same site.
Iron Age settlement and landscape researchMain Iron Age context approximately 450 BCE–500 CE; earlier occupation separately identifiedStratified rice dates, settlement deposits and regional household comparisons

The 2014 study proposes a later Neolithic-to-bronze sequence than the fourth-millennium bronze dates reported during early research. Solheim's 1972 essay records exploratory fieldwork and ambitious regional-priority claims. Those claims are historical interpretations, not this atlas's verdict.

The institutional architecture record treats Narendraditya's patronage as a plausible interpretation rather than an unambiguous surviving commission. The 2019 submission groups Phanom Rung with other sanctuaries, emphasizing landscape and connections rather than a single isolated monument.
Sacred landscape and regional patronageApproximately tenth–thirteenth centuries CE; modern restoration and designation separatedArchitecture, inscriptions, stylistic analysis and tentative-list documentation

The architectural record reports earlier brick remains beneath later stone construction and dates principal forms broadly to the eleventh–twelfth centuries. The sculpture record regards a naga-sheltered Buddha as later than the principal sanctuary, illustrating why an object's present setting cannot date the entire building.
Regional sanctuary and artistic networksMain eleventh–thirteenth centuries CE; earlier building and modern restoration distinguishedArchitectural stratigraphy, inscriptions, sculpture comparison and national museum interpretation

The 2021 study combines dating and geological methods; an age for stone provenance is not automatically the date of carving or use. The heritage record groups several jar localities rather than a single city or royal capital.
Megalithic landscape and chronological researchProposed jar placement in the late second–first millennium BCE; later first–second millennium CE activity distinguishedStone-working contexts, luminescence, radiocarbon, geological analysis and collaborative fieldwork

The heritage record distinguishes an earlier ninth-century context from major eleventh-century architecture instead of assigning the whole complex one construction date. The evaluation relates architectural arrangement to the plateau setting and religious function; it does not describe every surrounding community.

The heritage account connects the temple groups with Ishanapura; the identification should not erase the wider settlement and its workers. The evaluation considers brick sanctuary forms and sculpted stone elements, including octagonal buildings, as evidence of regional architectural experimentation.

The heritage account places the eleventh-century citadel over an earlier administrative context rather than presenting the city as a wholly new settlement. The evaluation considers excavated structures and objects alongside transmitted history; later standing fabric and earlier layers are not interchangeable.

Evidence-first orientation
Chronology, language, labor, and living landscapes
Six cited evidence notes explain modern regional frames, material classifications, partial archives, river landscapes and work, connected worlds, and living heritage.
Regional names do not reconstruct borders
The Champasak and Hanoi records concern different landscapes, periods and political scales. Mainland Southeast Asia and its present countries help locate evidence; they do not reconstruct ancient nationality, ownership or allegiance.
The Ban Non Wat chronology classifies layers and dated events; Dvaravati art history compares religious objects. Neither method identifies an unchanged people. Bronze use, sculpture style, language and political authority must remain separate questions.
Sambor Prei Kuk's royal and religious evidence and Mrauk-U's retrospective guide have different purposes. Inscriptions and chronicles favor particular institutions. Attribute foundation stories and transmitted names by their date and genre instead of treating them as social censuses.
The regional household study highlights gaps in domestic evidence, while the Champasak record connects settlement with water and building. Discuss farming, fishing, craft, gender, maintenance and patronage; dependent labor or slavery requires evidence, not an assumed status for every builder.
Religious sculpture and layered urban evidence reveal active local choices within wider exchanges. Language, patronage and material similarities do not prove one migration, a direct route, universal conversion, or passive Indianization or Sinicization.
Mrauk-U's guide and Preah Vihear's inscription decision are attributed heritage records, not endorsements of this atlas. Modern borders, recognition and community membership are not decided here. Coarse points grant no access; evidence cannot establish personal ancestry or descent.

The Historical Atlas is free, uses no DNA, and is separate from the paid report. It cannot establish identity, religion, ethnicity, ancestry, descent or community membership.
A selective regional collection, not a people census
This editorial release contains 20 profiles. This is a selective collection, not a census or complete mainland history. Existing Ban Chiang, Pyu cities, Si Thep, Angkor, Mỹ Sơn, Óc Eo and Cổ Loa contexts are linked rather than duplicated. Less visible rural households and communities are not absent from the past.
