Thaification

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, and later of Bangkok.

Thaification was a step in the creation in the early 20th century of the Thai nation state in which Central Thais 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.
