Thaification

Thaification, or Thai-ization, is the process by which people of different cultural and ethnic origins living in Thailand become assimilated to the dominant culture of Thailand, 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 Thai persons from others.
