After the Roman domination, the Byzantines ruled Val di Magra, keeping a particularly tight control over Luni region. The reason for this interest was Luni's port, ideal base for the Byzantine fleet which had its main port on Sardinia. Indeed, for a period the headquarters of the navy were moved to Filattera, and this confirms the importance of the location to the Byzantines.

 
         
 
In 643 the Longobards entered Val di Magra, making it an extension of the duchy of Lucca. Starting from the X century Luni hosted a bishop palace, installed there by Emperor Otto I. At the same time, the oriental regions of Lunigiana were re-organised into feuds, that had to pay tribute to the Emperor; it is from these feuds that the families of Malaspina and Este would eventually emerge, to rule for many years over the Lunigiana and over vast part of northern Italy. Also, during the feudal period many small villages in the Valle were founded: Aulla, Bagnone, Villafranca, Zeri.
