The populations appearing on the images selected, live in a zone South of a line going from Savannaket (Laos) to Quang-Tri (Vietnam). This area does not include all the "montagnards" or so-called "minority" ethnic groups of Cambodia, Laos and Vietnam.
We have addressed two human groups only, as distinguished by specialists on linguistic grounds:
Austronesians (also called "malayo-polynesian") and
Austro-asiatics (so called "mon-khmers"). Austro-asiatics are also found North of the Quang-Tri – Savannaket line, where however they live among larger ethnic groups (Tai-Kadai, Miao-Yao and Tibeto-Burmese) who have significantly influenced their mode of living. The groups selected are not solely characterized in linguistic terms. Cultural features are also important: systems of lineage, a mode of living in symbiosis with the forest once largely based on swiddening agriculture, and a spiritual life marked by a generalized animism where numberless "yang" genii crowd the environment. Domestic animals are frequently sacrificed to them, particularly water buffaloes, in spectacular rituals.
The bibliography on this site gives more information about the characteristics or location of these very diverse groups (the main ones are named – according to the current Vietnamese spelling: Hre, Gia-Rai, E-de, Ba-Na, Co-Ho, Ma, and so on). They are grouped here as we have found them in most studies. Ethnolinguistic maps are also available on the Internet, such as the ones from the
University of Texas.
The collective denomination “Montagnards” was not historically the first by which they came to be known. Their immediate neighbours, the Vietnamese, made them known first under the pejorative name "moï". Westerners and among them French colonizers took up this word sometimes replacing it with its translation in their language: "sauvages"
