[1][2] He was viscount of Narbonne 1071 until his death in the Holy Land in 1106.
[2] Quite young when his father Viscount Bernard died, the first years of Aimery take place in the shadow of his uncle, Pierre Bérenger, who asserted his hold on Narbonne both as viscount and as archbishop of Narbonne, despite the opposition of the pope and his legates.
According to a missing charter referred to in later documents, in 1093 Aimery authorized a group of Benedictine monks to settle in the forest of Fontfroide, a modest starting point for what would later become one of the most powerful monasteries in the region, Cistercian Abbey of Fontfroide.
[3] Leaving for the Holy Land around 1103, Aimery died soon after.
His eldest son Aymeri II succeeded him.
