Simon de Montfort was one of those extraordinary men who deflect the course of history. He was descended from Rollo the Norman, and took his name from a small domain which he held in the Ile-de-France, on the road from Dreux to Paris. Physically, he was blond, tall, broad-shouldered, distinguished in appearance, and full of activity. Naturally enough his character has been both praised and blamed to the _n_th power. Peter de Vaux-Cernay praises his eloquence, affability, faithfulness in friendship, his rigid chastity, and rare modesty. Sismondi, in a famous passage, says of him: “an able warrior, austere in his personal habits, fanatical in religion, inflexible, cruel and treacherous, he combined all qualities calculated to win the approval of a monk.” The important thing is that de Montfort was, above all, a soldier, and a soldier of a type not uncommon in French history, from the First Crusade to the wars of the French Revolution, in that he was consumed with a sense of the sacredness of his cause. As in so many determined men of strict sexual morality, in him fairness was all but swallowed up in fanaticism. Such men are ill understood by men of English culture. It is a commonplace, for example, that no character approaching the type is to be found in the long gallery of Shakespearean portraits. Meanwhile, although the student may smile at the fanatic, he will do well to remember the greatness of the work done in the world by fanatics ... those curious creatures. Directly, by keeping alive crusading activity in Languedoc, de Montfort preserved the moral unity of Christendom. That unity, rescued from the grave peril which threatened it in the beginning of the thirteenth century, endured until destroyed by the great sixteenth century centrifugal movement, which is only just beginning to subside. Indirectly, he broke down the Provençal culture, and established the French monarchy upon the Mediterranean, thus establishing the permanent unity of the French nation. But from de Montfort, as from all men, the future was hid.
