Archbishop Robert excommunicated Palatine Denis and put Hungary under an interdict on 25 February 1232, because the employment of Jews and Muslims continued despite the Golden Bull of 1231. Since the archbishop accused the Muslims of persuading Andrew to seize church property, Andrew restored properties to the archbishop, who soon suspended the interdict. Upon Andrew's demand, Pope Gregory sent Cardinal Giacomo di Pecorari as his legate to Hungary and promised that nobody would be excommunicated without the pope's special authorization. Although Andrew departed for Halych to support his youngest son in a fight against Daniel Romanivich, he continued his negotiations with the papal legate. On 20 August 1233, in the forests of Bereg, he vowed that he would not employ Jews and Muslims to administrate royal revenues, and would pay 10,000 marks as compensation for usurped Church revenues. Andrew repeated his oath in Esztergom in September.
