The territory was infiltrated by the Germanic Franks from the 4th century, and was abandoned by Rome in AD 406, after which it became part of the Kingdom of the Franks. The Salian Franks who settled in the area are often described as the ones having brought the Germanic language to present-day Luxembourg, since the old Frankish language spoken by them is considered by linguists to be a direct forerunner of the Moselle Franconian dialect, which later evolved into, among others, the modern-day Luxembourgish language.
