Plaek Phibunsongkhram
In 1939, when the Society changed its name to the Thailand Research Society in conformity with the nationalist policies of the government of Field Marshal Plaek Phibunsongkhram, the title of the journal was changed to "The Journal of the Thailand Research Society" from Vol. 32/1 (Sept. 1940) to Vol. 35/2 (Sept. 1944).
