In Support of Pontifical Power: The Papacy and the Papal States’ Baronial Nobility, 1417–49

This article addresses the baronial nobility's much-neglected role in supporting the reestablishment of pontifical power in the wake of the Western Schism. In doing so, this article stresses how acts of noble revolt were complemented by extensive patterns of collaboration in the Papal States’ government, armies, and relations with other principalities. The nobility proved to be a fundamental source of support—a support that was theorized around and expressed in the language of fealty and devotion. In light of this, my analysis further contributes to the study of the perseverance of noble power and ubiquity of transregional factions in late medieval societies.
