For the duration of the war, the Vatican kept up full diplomatic relations with the Ustaša state (granting Pavelić an audience), with its papal nuncio in the capital Zagreb. The nuncio was briefed on the efforts of religious conversions to Roman Catholicism. After the Second World War was over, the Ustaše who had managed to escape from Yugoslav territory (including Pavelić) were smuggled to South America. It is widely documented that this was done through rat lines operated by members of the organization who were Catholic priests and had previously secured positions at the Vatican. Members of the Illyrian College of San Girolamo in Rome were reputedly involved in this: friars Krunoslav Draganović, Petranović, and Dominik Mandić.
