This volume offers a comprehensive and authoritative account of the history of a complex and varied body of ideas over a period of more than one thousand years. A work of both synthesis and assessment, The Cambridge History of Medieval Political Thought presents the results of several decades of critical scholarship in the field, and reflects in its breadth of enquiry precisely that diversity of focus that characterized the medieval sense of the "political," preoccupied with universality at some levels, and with almost minute particularity at others. Among the vital questions explored by the distinguished team of contributors are the nature of authority, of justice, of property; the problem of legitimacy, of allegiance, of resistance to the powers that be; the character and functions of law, and the role of custom in maintaining a social structure.
