Pierre de La Chapelle

He was the son of Gauthier de Villebéon, lord of Villebéon and La Chapelle, Grand Chamberlain of France, and Aveline of Nemours.^[2][3][4] He was the treasurer of the Basilica of Saint Martin, before being elected bishop of Paris in 1208.^[3][4][5]

De La Chapelle is notable for being one of the chief persecutors of the Amalricians, obtaining undercover information that shed light on the inner workings of the group ^[6] and burning at the stake a number of members^[3][4] and David of Dinant's works.^[5] In 1211, he also took part in the Albigensian Crusade, even if only for a few months. ^[3][4][5]

In 1212, he attended the council held by a papal legate, Robert de Courçon, where regulations were put in place concerning the chapter's office of chancellor^[3][4]. In 1217 he welcomed the Dominican Order in Paris^[3][4].

In 1218, de La Chapelle went on the Fifth Crusade. He died the following year, during the siege of Damietta^[3][4][5].
