Montagnard (ˌmɒn.tənˈjɑːrd) is an umbrella term for the various indigenous peoples of the Central Highlands of Vietnam. The French term Montagnard (mɔ̃.ta.ɲaʁ) signifies a mountain dweller, and is a carryover from the French colonial period in Vietnam. In Vietnamese, they are known by the term người Thượng (highlanders), although this term can also be applied to other minority ethnic groups in Vietnam. In modern Vietnam, both terms are archaic, and indigenous ethnic groups are referred to as đồng bào (compatriots) or người dân tộc thiểu số (minority people). Earlier they were referred to pejoratively as the mọi. Sometimes the term Degar is used for the group as well. Most of those living in the United States refer to themselves as Montagnards, while those living in Vietnam refer to themselves by their individual ethnic group. The Montagnards are most covered in English-language scholarship for their participation in the Vietnam War, where they were heavily recruited by the Army of the Republic of Vietnam (ARVN) and its American and Australian allies. The Montagnards tended to be Christian at a higher proportion than that of the Viets, and the North Vietnamese were seen by some Montagnards as propounding a heavily centralized state that would not value Montagnard local priorities or religious practices. Below is a list of officially recognized ethnic groups in Vietnam that are indigenous to the Central Highlands and nearby areas, with a total population of approximately 2.25 million. They speak Austroasiatic languages of the Katuic and Bahnaric branches, as well as Chamic languages (which belong to the Austronesian language family). Population statistics are from the 2009 Vietnam Population Census.
