Books by Malcolm (University of Reading Barber

Malcolm Barber traces the origins and spread of Cathar dualist ideas, assesses their attraction for contemporaries, and describes the reaction of the ecclesiastical and lay authorities in the form of preaching campaigns, intellectual refutation, crusade, and inquisitorial investigations.

For this new edition, Malcolm Barber has revised each chapter, taking into account the historiography of the past decade and bringing the text up to date.
