Pugnas historiográficas por la herejía medieval: los herejes dualistas (siglos XII-XIII)

The historiographical controversy surrounding the Dualistic heretical resurgence in twelfth-century Western Europe is still very much alive. This piece aims to address two main objectives: a) to present a historiographical balance on the Western dualist heresy or “Catharism”, and b) to propose a temporal distinction to explain the historiographical disagreements about the twelfthand-thirteenth-century Dualistic heretical occurrence. By considering this documentary-chronological division, it is possible to understand the differences between the two opposing interpretive schools.
