The Rhineland, the haunt of the earliest known Cathars in 1143, was to receive the attentions of the first Inquisitor, Conrad of Marburg. Conrad was an extreme ascetic who brought a campaign of terror to the Rhineland with his two henchmen, Conrad Tors, a Dominican, and a one-eyed, one-handed layman called John. Almost everywhere they went, they found heretics of all denominations. Due to a combination of his own blinkered zealotry, and ignorance of what actually constituted Cathar belief, Conrad thought he had unearthed a heresy that he dubbed ‘Luciferanism’. No doubt he remembered — or had it pointed out to him — that ‘Cathar’ meant someone who indulged in satanic rites which included obscene kisses on the rear ends of cats. On top of this fiction, Conrad constructed an elaborate demonology that possibly also contained elements of undigested Cathar doctrine, such as the belief that the devil had created the world. The heretics were thought to worship the devil and engage in sexual orgies. Such beliefs were not new: exactly the same accusations (minus the cats) had been levelled at the Orleans heretics in 1022. Conrad relayed his findings to Gregory, who promptly issued the bull Vox in Rama in June 1233 denouncing the Luciferans.
Conrad’s procedure, if it can be called that, was swift and brutal. If the unfortunates whom the trio apprehended were adjudged guilty, they were burnt the same day without any further enquiries taking place. Hundreds, perhaps thousands, of innocent people — most of them simple, unlettered believers — met their deaths. In amongst them were a small percentage of Cathars. The level of hatred Conrad generated was astonishing. He achieved a notoriety of de Montfortesque proportions within months. He went a step too far, however, when he accused Count Henry II of Seyn of heresy. Count Henry demanded the right to a fair trial, and Conrad’s case against the count collapsed when it became apparent that the witnesses Conrad had called were amongst Henry’s enemies, and the Archbishops of Trier and Mainz wrote to Gregory to complain about Conrad’s behaviour. Conrad reacted by promptly calling for a Crusade against Henry and his supporters. On 30 July 1233, while Conrad was organising his Crusade, a local Franciscan decided to take matters into his own hands. He caught up with the Inquisitor as he was on his way back to Marburg from Mainz, and stabbed him to death.
Northern France and Flanders were subject to the attentions of Robert the Bulgarian, whose name suggests he was a Cathar who had renounced his former faith. Like Conrad, he was a fanatic of the most zealous kind, whose methods were ‘ferocious and arbitrary’.74 Chronicles report that Robert could detect heretics by foibles of speech and gesture; another spoke of a document, which, when placed on a suspect’s head, made them say whatever Robert wanted.75 Robert’s crowning achievement was his participation in the burning of 180 heretics at Mont Aime in Champagne in the spring of 1239. The area had been known for Catharism since the twelfth century, and the mass incineration was no doubt intended to spread further terror, and also to show bishops from around a dozen local sees what had happened to the heretics who had been uncovered in their areas.
Robert was still conducting his idiosyncratic campaign against the devil and all his works as late as 1244, but was eventually disgraced and imprisoned for his excesses.
