Alix de Montmorency

Alix de Montmorency (died 24 February 1220/1221) was a French noblewoman. Her parents were Bouchard V de Montmorency and Laurette, daughter of Baldwin IV, Count of Hainaut and Alice of Namur.

Life
In 1190 Alix married Simon de Montfort (c. 1175 – 25 June 1218), who later became the 5th Earl of Leicester. She accompanied her husband on his campaigns during the Albigensian Crusade and like her husband, she was very pious. Both of them had come under the influence of Fulk of Neuilly and they were patrons of the Dominican Order.

Albigensian Crusade
Alix participated in the councils of the crusaders and recruited reinforcements in France. In 1217, she imprisoned the Jews in Toulouse. She went to the French court with Folquet de Marselha to plead for support, but she was nearby when her husband was killed as he besieged Toulouse. After this she returned to her family's estates near Paris.
