After a new research carried out by Mr. Houmphanh Rattanavong, Lao historian the word tai or thai does mean people ( khonh) , people of a certain profession or people of a certain geographical location but none of an ethnic nor race. Tai Lue, Zhuang/Liao, tai Mao/Mo, tai Ahom, tai Khamti, tai Dam, tai Deng, tai Khao/Done, Phoutai and other tai are Lao/AiLao who used to live or still living in Yunnan or Montse ( Nongse in Lao )the former kingdom of AiLao. The people whom Siamese classified as Thai Yai are in fact Lao/AiLao who moved from Mao/Mo city state, during the Ming dynasty Chinese called them AiLao Shan or AiLao mountain. The citizen of Lane Na kingdom included Yuan/Yonok and people whom Siamese classified as Thai Isan are Lao as we are Lao Vientiane. There was no Thailand as a country nor Thai as a people before Marshall Pitt Bull Songkhram renamed Siam for Thailand to forced everyone living in the new renamed country and annexed territories to be Thai. Monsieur Lunet de Lajonquiere, French researcher affiliated with L'Ecole Francaise d'extreme-Orient who in line with the Bangkok directory of 1904 ( census) mentioned in his " Le Siam et les Siamois" booklet there were 1 766 000 Siamese, 1 354 000 Lao, 753 000 Malay and 533 000 Chinese but none of tai or thai as people in Siam.
