The territory was infiltrated by the Germanic Franks starting from the 4th century, and was abandoned by Rome in 406 AD. The territory of what would become Luxembourg now 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, among others, into the modern-day Luxembourgish language.
