action had made England a fief for ever of the Holy See! Gregory VII and Innocent III are the two greatest and most sincerely religions of the medieval Popes, and they carried the power of the Papacy to a height which excites the amazement of the modern historian. But they were at the same time the most militant of the Popes, and on the least provocation they set armies—even the most barbaric and ferocious troops in Europe—in motion to carry out their imperial commands. They arrogated the power of deposing monarchs, and thus encouraged civil war and the ambitions of neighbouring kings.
The rise of heresy and of protests against the corruption of the Papacy was another very grave pretext of the Church to support the military system. In the days of Gregory VII a body of Puritans known as the Patareni spread over the north of Italy, and Rome encouraged a few soldiers to lead armed mobs against them and drown their idealism in blood. Innocent III has a more terrible stigma on his record. The Albigensians, an early type of Protestants, were spreading in the south of France, and the Pope sanctioned a "crusade"—an expedition, largely, of looters and cut-throats—against them from all parts of France. The appalling deceit practised by the Papal Legate and sanctioned by the Pope, the ferocity of the campaign, and the desolation brought on one of the happiest and most prosperous provinces of France, may be read in any history of the thirteenth century. Tens of thousands of men, women, and children were savagely put to death. And this was only the beginning of the Papal war on heresy, which from the thirteenth century never ceased to spring up in Europe until it won its right of citizenship in the Reformation.
