Thaification

A name board on a wat in Chiang Mai written in the Tai Tham alphabet ("Lan Na alphabet", อักษรธรรมล้านนา). The use of this script was discouraged and the Northern Thai language is now written with the Thai alphabet.

Thaification, or Thai-ization, is the process by which people of different cultural and ethnic origins living in Thailand become assimilated to the country's dominant culture:, that of central Thailand.

Thaification was a step in the creation in the 20th century of the Thai nation state in which Central Thai people occupy a dominant position, as opposed to the historically-multicultural kingdom of Siam. A related term, "Thainess", describes the particular characteristics that distinguish the Thai from others.
