Antebellum in Latin is literally "ante" (before) "bellum" war, and you'll find the word loosely used by historians to address a myriad of prewar societies. However, in terms of overall or general historiography, you'll be hard pressed to find any major historical works where "antebellum" is associated with any time-frame or era other than the pre-Civil War American South... even when used by German or French Authors, in terms of a historiographical term, antebellum is used to describe the period between the American War of 1812 through the Civil War.

(Pardon the lack of citation, but in this instance, the lack of citation evidences my point).
