In The Great Heresies, Hilaire Belloc takes the reader on a fast and furious tour of European history seen through the lens of its chief religious conflicts - Arianism, 'Mohammedanism' (Islam), Albigensianism, the Reformation, and what he terms 'The Modern Phase.'

A study of the history and beliefs of Catharism.

Some of the most portentous events in medieval history—the Cathar crusade, the persecution and mass burnings of heretics, the papal inquisition—fall between 1000 and 1250, when the Catholic Church confronted the threat of heresy with force. Moore’s narrative focuses on the motives and anxieties of elites who waged war on heresy for political gain.
