ガリア・ベルギカ
During the 1st century AD (estimated date 90 AD), the provinces of Gaul were restructured. Emperor Domitian reorganized the provinces in order to separate the militarized zones of the Rhine from the civilian populations of the region. The northeastern part of Gallia Belgica was split off and renamed Germania Inferior, later to be reorganized and renamed as Germania Secunda. This included the eastern part of modern Belgium, the southernmost part of the modern Netherlands, and a part of modern Germany. The eastern part was split off to become Germania Superior (parts of western Germany and eastern France) and the southern border of Gallia Belgica was extended to the south. The newer Gallia Belgica included the cities of "Camaracum" (Cambrai), "Nemetacum" (Arras), "Samarobriva" (Amiens), "Durocortorum" (Reims), "Dividorum" (Metz) and "Augusta Treverorum" (Trier).
