 In 1309, the last known Cathar perfect, Guillaume Bélibaste, fled Catalonia with Philippe of Alayrac.The latter, on his return home after ten years of exile, was probably captured and burned.On hearing the sound of an approaching large company from Routiers in 1366, the officers of the Bailiwick of Carcassonne ordered the inhabitants of the castle at Alairac — which belonged to Jean d'Armagnac — to fortify it and destroy the surrounding area.
