Peopling of Thailand
The peopling of Thailand refers to the process by which the ethnic groups that comprise the population of present-day Thailand came to inhabit the region. == Gradual inland migration of Tai peoples from China == The Tai migration from the northern mountains into Thailand and Laos was a slow process, with the Tai generally remaining near the mountainous area in the region, where they were able to use their specialized agricultural knowledge relating to the use of mountain water for rice production.
