Background
He inherited three hilltop castles near modern-day Lastours from his father.
He inherited three hilltop castles near modern-day Lastours from his father.
He was a patron of the troubadours, including Peire Vidal. Allegedly, Pierre-Roger advised Trencavel to remain in the castrum rather than meet the crusader army in the open field, because he was outnumbered. After Raimond-Roger surrendered Carcassonne, Pierre-Roger managed to return to his own castles.
He abandoned the Cabaret castles, but was granted lands near Beziérs in return.
He successfully defended his castles against Simon de Montfort, 5th Earl of Leicester, but months later capitulated without military actions.
