アルフォンソ2世
In 1178, Berenguer arbitrated a dispute between King Alfonso II of Aragon and Berenguer de Fluvià over rights at the castle of Forès. 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.
