Annam

Annam was the central region in those parts of French Indochina that eventually became South Vietnam. This area contains the Central Highlands, which are the traditional home of the Montagnard peoples, who consider themselves ethnically distinct from the lowland Vietnamese.

Its traditional capital was Hue, and it was often considered the center of classic Vietnamese culture. Bao Dai had been Emperor of Annam before entering the French Indochinese government.

Annam generally corresponded with the II Corps tactical zone of South Vietnam. While the core of the Ngo Dinh Diem government were from the north (i.e., Tonkin), Diem himself was an Annamese Catholic.
