The Frankish Papacy, which lasted from 756 to 857, was a period marked by the dominance of the kings of the Franks over the Roman Papacy. Pepin the Short, Charlemagne, and Louis the Pious played significant roles in the selection and administration of popes, leading to the establishment of the Papal States. This period was crucial in the transformation of Rome’s authority and the establishment of the Papacy as a central institution in medieval Western Christendom.
