This interdisciplinary volume sets out to illuminate medieval thought, and to consider how the underlying values of the Middle Ages exerted significant influence in medieval society in the West. The book situates the Christian Church in the West as a framing ideology of the Middle Ages, and considers ideology from four angles: as a means of defining power; as a way of managing power; ideology as an influence on daily living and societies; and the ways in which ideology associated with the Middle Ages continues to influence understandings of past and present. A focus on southern European case studies has been chosen as a means of enriching and complicating study of the Middle Ages.
