The moment
A stone inscription dated 1292 and attributed to King Ram Khamhaeng portrays Sukhothai, the first major Tai kingdom, as a prosperous Buddhist realm whose king patronised monks of the Sri Lankan lineage brought north from Nakhon Si Thammarat. It is the earliest known text in Thai script. Since the 1980s some scholars have argued that the stone is a 19th-century creation, though most accept it as at least partly genuine.
