“Fierce competition for power produces fierce discursive competition. In this grand and sane book, armed with many lights (intelligence, narrative skill, learning) R. I. Moore re-enters the territory of Europe's ferocious medieval competition for theological orthodoxyCCCCCC wherever he ventures, he illumines what had been dark.”

The War on Heresy

by R. I. Moore

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.
