Origin from 1044
Where Mahayana Buddhism and Hindu court traditions had earlier been prominent across mainland Southeast Asia, a Theravada reform movement drawing on Sri Lanka's own sangha reforms and on the older Theravada heritage preserved among the Mon of southern Myanmar took root from the eleventh century. King Anawrahta's unification of Myanmar under Theravada patronage from 1044 gave the reform its first state backing; over the following two and a half centuries the same reform tradition spread into Thailand, then into Cambodia and Laos, until Theravada stood as the dominant, eventually state, religion across the region, a position Cambodia, Myanmar, Thailand and Laos all still hold.
Facts
Dates
Start Year1044 marks Anawrahta's accession in Myanmar and the reform movement's first state patronage; the same consolidation reached Thailand, Cambodia and Laos at different, later points across the following two centuries, named in the description rather than compressed into one false single date. End YearBy the late thirteenth century the reform had reached Thailand; Cambodia and Laos completed the same consolidation somewhat later, into the fourteenth and fifteenth centuries, so 1300 marks Theravada's regional consolidation as a dominant force rather than its final country-by-country completion.

How Theravada Buddhism Became Dominant in Southeast Asia
This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
Theravada Buddhism consolidates as the dominant tradition across mainland Southeast Asia from the eleventh century onward, in a region where Mahayana Buddhism and Hindu court traditions had earlier been prominent. The reform drew on Sri Lanka's own sangha reforms and on an older Theravada heritage already preserved among the Mon of southern Myanmar, so the consolidation carried an established lineage forward rather than introducing something wholly new.
King Anawrahta's unification of Myanmar under Theravada patronage from 1044 gave the reform its first state backing, the same royal sponsorship pattern that had carried Buddhism into Sri Lanka centuries earlier. Over the following two and a half centuries the same reform tradition spread into Thailand, then into Cambodia and Laos, court by court, until Theravada stood as the region's dominant religion.
What changed for the tradition's spread is a mainland Southeast Asian bloc unified under one shared form of Buddhism rather than several competing traditions, a position Cambodia, Myanmar, Thailand and Laos all still hold today as their own state supported religion, and this atlas records the outcome as dominant, the strongest of the spread status readings it tracks.

Myanmar, Thailand, Cambodia and Laos, at different points across roughly the eleventh to fourteenth centuries. The map places this across the wider Southeast Asia region rather than any single country, since the consolidation genuinely spans several of them.
