The next "crusade" did not even take place in the East, and its target was not Muslims but a religious group called the Cathars. Based in Albi, France, they were also called Albigenses (al-buh-JIN-seez), and they practiced a faith similar to Manichae-ism. Like the Manichees long before, the Albigenses believed that all of existence was a battle between evil and good, and that they alone were capable of understanding the terms of this battle.
The church considered this heresy, and at first it dealt with the Al-bigenses by sending them missionaries such as St. Dominic (c. 1170-1221). Dominic later founded the Dominicans, a mendicant (that is, dependent on charity for a living) order of fri-ars—neither monks nor priests, but preachers and teachers. Another mendicant order was the Franciscans, founded by St. Francis of Assisi (uh-SEE-see; c. 1182-1226).
Innocent III ultimately decided to deal harshly with the Albigenses, and in 1208 launched the so-called Al-bigensian Crusade. Invaders eager for land and treasure swarmed over southern France, seizing the estates of the nobility and replacing bishops who had sympathized with the Cathars.
The Albigensian Crusade, which ended in 1229, had a powerful effect on history. By displacing much of France's nobility, it greatly strengthened the French king, and from then on France would have a powerful central government in contrast to the looser system that had prevailed under feudalism. This in turn tied the French royal house close to the church, and eventually the two would become inseparable. The Albigensian Crusade also led to the establishment of the Inquisition by Pope Gregory IX in 1231.
The Inquisition, which lasted until the 1300s, was the name for a court through which the church investigated, tried, and punished cases of heresy. Many inquisitors, Church officials appointed to oversee investigations, were excessive in their methods, but generally the Inquisition was not as harsh as is popularly believed. During the 1200s in France, for instance, only about one percent of accused heretics were burned at the stake; some ten percent were imprisoned, and the rest received lesser sentences. When modern people talk about the horrors of the Inquisition, what they are actually referring to is the Spanish Inquisition, an entirely separate system (see box, "The Iberian Peninsula," chapter 19).
