Mainstream thought on “Thainess” has been firmly defined by significant intellectuals
since the reign of King Rama V. Intellectuals adjusted the key aspects and significance of
“Thainess” periodically in responded to the changing political contexts. However, the
original structure of “Thainess” was retained throughout these adjustments. As a result, the
mainstream construction of “Thainess” has an overwhelming power upon the ways of
thinking of Thai people.
