The Republic of St. Peter seeks to reclaim for central Italy an important part of its own history. Noble's thesis is at once original and that the Republic, an independent political entity, was in existence by the 730s and was not a creation of the Franks in the 750s.
Noble examines the political, economic, and religious problems that impelled the central Italians—and a succession of resolute popes—to seek emancipation from the Byzantine Empire. He delineates the social structures and historical traditions that produced a distinctive political society, describes the complete governmental apparatus of the Republic, and provides a comprehensive assessment of the Franco-papal alliance.
Very solid, does away with a lot of older scholarship pertaining to the foundation of the Papal States, Noble makes his case using very convincing evidence.
Thomas F. X. Noble in this book examines the origins and nature of papal lands in Italy. In the course of his discussion he untangles a thorny array of papal, Byzantine, and other sources, most of which use difficult terminology (vocabulary which may or may not have a very different legal meaning that previous or subsequent meanings, for example, or which may mean very different things in different contexts even within the period in question). His study perforce touches on the legal, social, and economic aspects of land-holding, political and military developments, and changes in papal governance (including the administrative styles and agendas of key popes). This work is an important prerequisite to study of subsequent papal developments.
