 On 11 July 1151, Roger Bernard married Cecilia, daughter of Raymond Trencavel, and became a vassal of the County of Barcelona.However, he avoided involving himself in the count's war of 1159 and concentrated on expanding his own zone of influence, as by a treaty with the lords of Dun in 1162.In 1185, he was finally constrained to fight alongside the count of Barcelona, Alfonso the Chaste, in southern France.
