Guigues IV of Forez

On 16 April 1224, he returned the places of Saint-Rambert, Bonson, Chambles, Saint-Cyprien and Saint-Just to the monastery of Île Barbe, declaring that they were allods held freely and that he and his predecessors had unjustly possessed them.

Guigues IV's primary motivation for crusading was to remove the sentence of excommunication that had been placed him for the alleged spoliation of monasteries and sheltering heretics.

[6] Likewise, by taking the crusader vow Guigues received relief from interest payments on his large debts and extensions on repayment of principal.

Theobald left the Holy Land to return home in September 1240, Guigues and Duke Hugh IV of Burgundy stayed behind to construct a fortress at Ascalon.

[1][8] The poet Eustache le Peintre de Reims wrote a short song in Old French, Amours, coment porroie chancon faire, about Guigues's participation in the Crusade.

[1] He named as his executors Jean de Bernin, the archbishop of Vienne; Beatrice, the countess of Albon; the abbot of Bénissons-Dieu; and the dean of Montbrison.
