Annam
Annam is a historical designation used in East Asian and Western sources to refer to a central region of Vietnam. The name derives from the Sino-Vietnamese 安南, commonly translated as “pacified south” or “peaceful south.” In traditional usage, Annam referred to the central coastal area of modern Vietnam, between Tonkin in the north and Cochinchina in the south, and it was often associated with the Nguyễn dynasty heartland around Huế.
Historically, Annam appears in various periods as the name for the territory governed by Vietnamese dynasties.
In modern usage, Annam is largely a historical term. It appears in scholarly works and historical texts
