First Published in 2005. The book covers four periods, each with a different focus. From 300 to 750 Canning examines Christian ideas of rulership. The often neglected centuries from 750 to 1050, the Carolingian period and its aftermath, are given special attention. From 1050 to 1290 the conflict between temporal and spiritual power and the revived legacy of antiquity comes to the fore. Finally in the period from 1290 to 1450, Canning focuses on the confrontation with political reality in ideas of church and state, and in juristic thought.

This collection of essays, written by leading experts, showcases historiographical problems, fresh interpretations, and new debates in medieval and Renaissance history and political thought. Recent scholarship on medieval and Renaissance political thought is witness to tectonic movements. These involve quiet, yet considerable, re-evaluations of key thinkers such as Thomas Aquinas and Machiavelli, as well as the string of lesser known "political thinkers" who wrote in western Europe between Late Antiquity and the Reformation. Taking stock of thirty years of developments, this volume demonstrates the contemporary vibrancy of the history of medieval and Renaissance political thought. By both celebrating and challenging the perspectives of a generation of scholars, notably Cary J. Nederman, it offers refreshing new assessments. The book re-introduces the history of western political thought in the Middle Ages and the Renaissance to the wider disciplines of History and Political Science. Recent historiographical debates have revolutionized discussion of whether or not there was an "Aristotelian revolution" in the thirteenth century. Thinkers such as Machiavelli and Marsilius of Padua are read in new ways; less well-known texts, such as the Irish On the Twelve Abuses of the Age, offer new perspectives. Further, the collection argues that medieval political ideas contain important lessons for the study of concepts of contemporary interest such as toleration. The volume is an ideal resource for both students and scholars interested in medieval and Renaissance history as well as the history of political thought.

The papers collected in this volume fall into three main groups. Those in the first group are concerned with the origin and early development of the idea of natural rights. The author argues here that the idea first grew into existence in the writings of the 12th-century canonists. The articles in the second group discuss miscellaneous aspects of medieval law and political thought. They include an overview of modern work on late medieval canon law. The final group of articles is concerned with the history of papal infallibility, with especial reference to the tradition of Franciscan ecclesiology and the contributions of John Peter Olivi and William of Ockham.
