The Lombard invasion of 568 CE further disrupted the region, with the Germanic tribe overrunning much of central Italy and establishing duchies like Spoleto. Although the Pentapolis initially held under Byzantine administration, Osimo faced Lombard incursions; in 727 CE, King Liutprand captured it along with other Pentapolitan cities like Ancona and Rimini during his expansion beyond the Po River, briefly placing it under Lombard rule. However, imperial forces and papal diplomacy restored Byzantine oversight, and by 756 CE, following Pepin the Short's donation to Pope Stephen II, Osimo transitioned definitively to the Papal States as part of the expanded ecclesiastical territory, ending direct Byzantine presence in the area.
