This classic text outlines the development of the Papacy as an institution in the Middle Ages. With profound knowledge, insight and sophistication, Walter Ullmann traces the course of papal history from the late Roman Empire to its eventual decline in the Renaissance. The focus of this survey is on the institution and the idea of papacy rather than individual figures, recognizing the shaping power of the popes' roles that made them outstanding personalities. The transpersonal idea, Ullmann argues, sprang from Christianity itself and led to the Papacy as an institution sui generis.

During the Middle Ages, the popes of Rome claimed both spiritual authority and worldly powers, vying with emperors for supremacy, ruling over the Papal States, and legislating the norms of Christian society. They also faced profound challenges to their proclaimed primacy over Christendom. The Medieval Papacy explores the unique role that the Roman Church and its papal leadership played in the historical development of medieval Europe. Brett Edward Whalen pays special attention to the religious, intellectual and political significance of the papacy from the first century through to the Reformation in the sixteenth century. Ideal for students, scholars and general readers alike, this approachable survey helps us to understand the origins of an idea and institution that continue to shape our modern world.

Valla (1407-1457) was the most important theorist of the humanist movement. His most famous work is the present volume, an oration in which Valla uses new philological methods to attack the authenticity of the most important document justifying the papacy's claims to temporal rule.

Unn Falkeid considers the work of six fourteenth-century writers who waged literary war against the Avignon papacy’s increasing claims of supremacy over secular rulers—a conflict that engaged contemporary critics from every corner of Europe. She illuminates arguments put forth by Dante, Petrarch, William of Ockham, Catherine of Siena, and others.

The Catholic Church is among the oldest, most secretive, institutions in the world, but in the sixteenth century a friar, Onofrio Panvinio, undertook ground-breaking investigations into the Church's history from Christ to the Renaissance. This study shows how his writings impacted on church and society, but also how he changed historical writing.
