Berenguer de Vilademuls[1] (died 16 February 1194) was the Archbishop of Tarragona from 1174 until his assassination. He was the sixth bishop after the re-founding of the diocese in 1118. His predecessor, Hug de Cervelló, had been assassinated in 1171.[2] Tarragona was in an internationally ambiguous position in Berenguer's time, between the Kingdom of France on the one side, the traditional suzerain of the Catalan counties, and the Crown of Aragon on the other, which had acquired the Catalan counties in the 12th century. In 1180 a council was convened in Tarragona that declared that thenceforth documents should be dated by the year of the Incarnation rather than in the traditional way, by the regnal year of the French kings.[3]
In 1178, Berenguer arbitrated a dispute between King Alfonso II of Aragon and Berenguer de Fluvià over rights at the castle of Forès.[4] He supervised for a time the comital administration in the counties of Roussillon and Cerdagne on behalf of Alfonso II, who was also count there. He was perhaps also in charge of the coinage of Catalonia in 1182–85.[5]
