 While Langobardia Major was fragmented and changing in many duchies and Gastalds, Langobardia Minor maintained for the duration of the Lombard kingdom (568–774) a remarkable institutional stability, remaining divided into the two duchies of Spoleto and Benevento.They were formed immediately after Lombard penetration, in the 570s, and the first dukes were Faroald in Spoleto and Zotto in Benevento.In the beginning they included geographically only the inland areas, leaving the Byzantines control of the coastal areas; only later (particularly during the reign of Agilulf, 591–616) Lombard possessions were extended also to the coasts.
