Thaification
Thaification refers to the systematic policies enacted by the Thai state to assimilate ethnic minorities into the dominant Central Thai culture, language, and national identity, often through enforced adoption of Thai customs, education in the Thai language, and curtailment of minority practices.[1] These efforts, rooted in early 20th-century nation-building, aimed to forge a unified Thai polity from a historically multi-ethnic society comprising groups such as Chinese immigrants, highland tribes, northeastern Lao, and southern Malay Muslims.[2] Intensified under Prime Minister Phibun Songkhram's regime from 1938 to 1944, key measures included the 1936 Private Schools Act limiting Chinese-language instruction, mandatory Thai naming conventions, promotion of Thai dress codes, and replacement of Islamic legal systems with Thai civil law in Muslim-majority areas.[2][1] While assimilation proved largely effective among urban Chinese communities, leading to their integration into Thai society by the mid-20th century, it encountered resistance from highland minorities through relocation programs and citizenship barriers, and from Malay Muslims, where cultural impositions fueled alienation and contributed to separatist violence persisting into the 21st century.[2][1] Over time, policies evolved from rigid uniformity toward selective accommodation of minority traits, though the core emphasis on Thai-centric identity remains.[2]
