summoned the King of France, the great lords and the knights, and the
clergy, secular and regular, of the kingdom to assume the cross and go
forth to extirpate from Southern France the Albigensians, "worse than the
Saracens;" and that he promised to the chiefs of the crusaders the

princes who were heretics or protectors of heretics.

Throughout all France, and even outside of France, the passions of

Twelve abbots and twenty monks of Citeaux dispersed themselves in all

leading spirits, one ordering and the other executing, Pope Innocent III.
and Simon de Montfort, neither saw the end of it. During these fifteen
years, in the region situated between the Rhone, the Pyrenees, the
