The Tyrrhenian Duchies are civil and military administrative divisions from the second half of the first millennium, originally dependent on the Byzantine Empire and governed by a military governor (dux). As in other Byzantine territories in Italy, the local nobility succeeded in transforming these duchies into autonomous states, only formally dependent on Constantinople. The principal of these states, which lasted more than five centuries, is the Duchy of Naples.
