== Buddhism in Thailand ==

Buddhism entered the territory of present-day Thailand over many centuries through contact with Mon- and Khmer-influenced polities. By the thirteenth and fourteenth centuries, with the rise of the Sukhothai kingdom, Buddhism had become a defining feature of Thai political and cultural identity; kings such as Ramkhamhaeng patronized the sangha, sponsored the translation of Pali and Sanskrit scripture, and positioned Buddhism as a unifying spiritual foundation for the kingdom. Over the following centuries, and especially under the Ayutthaya kingdom (1350–1767), Buddhist monasteries, or ''wats'', became central to community life, education, and governance, embedding Buddhism deeply within Thai society. In contemporary Thailand, the great majority of Buddhists adhere to Theravada Buddhism, and the monastic community remains organized under two major lineages, the Maha Nikaya and the Dhammayuttika Nikaya.

The intellectual foundation for later radical Buddhism was laid, somewhat paradoxically, by the crown itself. King Mongkut (r. 1851–1868) and his half-brother Prince Vajiranana (1860–1921) subjected received Buddhist tradition to sustained critical scrutiny, drawing on their encounters with Western missionaries and with reformist monastic currents in Ceylon and Burma. Mongkut's public dismissal of costly ritual practices as being of less value than mundane utility exemplified his broader willingness to challenge long-standing popular Buddhist observance. Prince Vajiranana, as head of the newly established Thammayut Order from 1893, systematized these reforms into a standardized ecclesiastical curriculum and administrative structure, formally institutionalizing state oversight of the Thai sangha in the process.

The reformed Buddhism this royal project produced redefined ''dhamma'' as a matter of rational inquiry and individual ethical cultivation rather than communal ritual observance. Keyes has argued that this shift carried a latent political charge: if religious authority now rested on each person's own study and practice of the dhamma, then in principle each person could also judge the conduct of political authorities against that same standard, rather than accepting the exercise of power as cosmologically pre-ordained by accumulated karmic merit.<ref>Keyes, Charles F. (1987). ''Thailand: Buddhist Kingdom as Modern Nation-State''. Westview Press, p. [TK].</ref> This reorientation — comparable in Keyes's analysis to the individualizing effect of the Protestant Reformation on European political consciousness — created space for the emergence of a genuinely activist Buddhist politics, the subject of the following section, even though the monastic establishment that produced the reform would later prove equally capable of suppressing its political implications.
