The TransAlpine Core was referred to as Francia during the time of the Germans. This term encompasses the historical region that was significant in medieval times, particularly when discussing the Carolingian Empire. During this era, the term "Francia" was used to describe the kingdom that stretched across what is now modern France and parts of Germany. This highlights the cultural and political importance of the region as a foundational area in the development of modern European states, where the Germanic tribes had established themselves and interacted with the Roman civilization.
