Carolingian Empire
Nomenclature

The term "Carolingian Empire" is a modern convention and was not used by its contemporaries. The language of official acts in the empire was Latin. The empire was referred to variously as universum regnum ("the whole kingdom", as opposed to the regional kingdoms), Romanorum sive Francorum imperium ("empire of the Romans and Franks"), Romanum imperium ("Roman empire"), or even imperium christianum ("Christian empire").
