 In 1126–1127, the period of his greatest activity in New Catalonia, he began encouraging a second Crusade effort.He began by compensating William V of Montpellier for the knights he had lent to Barcelona in 1124–1125 and by reconciling William with his son, Bernard IV of Melgueil, in order to strengthen the anti-Almoravid alliance.On 14 March 1129 he ceded this secular authority in the district of Tarragona to Robert Bordet, with whom he had an antagonistic relationship, with the title of "princeps Tarraconensis", effectively the archiepiscopate's vidame or "defensor".
