With the death of Simon de Montfort the Albigensian wars changed in character. Simon's son, Amaury de Montfort, was incapable of retaining the principality won by his father's sword, so he sensibly passed over his claims to the king of France. The struggle henceforth was purely political. Blanche of Castile's wise head solved the Midi tangle when she married her son Alphonse of Poitiers to the heiress of the Count of Toulouse, with the understanding that, should the young people die childless, Languedoc fell to the French Crown. Alphonse gave the Midi, says Molinier, the first intelligent administration it had received since the better times of the Roman Empire. When he and his wife died, returning from St. Louis' fatal crusade of 1270, the great southern land became a part of France. The Albigensian wars--for with reluctance one calls those years of bitter strife a crusade--delayed the completion of St. Sernin, whose main façade is gaunt and bare, and whose westernmost windows lack stone casements. When the Midi came under French rule the monks attained sufficient prosperity to erect the octagonal tower in five stories--each of lesser dimensions than the one below it. The upper stories used the miter arch so suited to brick. M. Enlart has called attention to the affinity of the _clochers Toulousans_ and the Lombard steeples. At present the underpinning of the tower obstructs the transept-crossing, but propping is better than demolition, which is what M. Viollet-le-Duc proposed in his blind enthusiasm for unity of style. The townspeople indignantly protested and the supreme beacon of this patroness city of art was saved. A proud boast of Toulouse is that the first Dominican monastery was established there, and by Dominic himself, the saint whom Dante called "the messenger and familiar of Christ."[229] The Friars Preachers, like the Franciscans (who, because of a new appreciation of their founder's character, are found sympathetic by many who still call a Dominican a "bloody sort of monk"), were agents for the quickening of the religious fervor of the XIII century. Both Orders were protests against abuses such as luxury, love of gold, and selfish privilege, which feudalism had helped to foster in the clergy.
