Roger II Trencavel was the Viscount of Carcassonne, Béziers, Razès, and Albi from 1167 or 1171 until his death. Until 1177 he used the title proconsul, usually as proconsul de Bitteris, but he abandoned the usage when he became a vassal of the Crown of Aragon. His government of his lands was characterised by increasing complexity, such as the development of the offices of seneschal and sub-vicar, but his later years are characterised by financial troubles and a "general malaise" perhaps brought about by his poor relations with the Church hierarchy in light of his favourable attitude towards Catharism.

Bernard Ato VI was the posthumous son and successor of Bernard Ato V, Viscount of Nîmes and Agde. He reigned from 1163 until 1214, when he surrendered his fiefs to Simon de Montfort, Earl of Leicester and leader of the Albigensian Crusade. Bernard Ato was not connected with Catharism nor were his lands, but his relationship to Raymond Roger Trencavel may have marked him off as an enemy of the Crusade by default, for he was a Trencavel, though he did not carry that name.

Raymond II Trencavel was the last ruler of the branch of the Trencavel viscounts of Béziers. His entire life was occupied by efforts to reverse the downfall the Trencavel had experienced during the Albigensian Crusade, but he ultimately failed.
