 Unsuccessfully, Pius attempted to dissuade the Italian Dictator Benito Mussolini from joining Hitler in the war. In April 1941, Pius XII granted a private audience to Ante Pavelić, the leader of the newly proclaimed Croatian state (rather than the diplomatic audience Pavelić had wanted). Pius was criticised for his reception of Pavelić: an unattributed British Foreign Office memo on the subject described Pius as "the greatest moral coward of our age." The Vatican did not officially recognise Pavelić's regime. Pius XII did not publicly condemn the expulsions and forced conversions to Catholicism perpetrated on Serbs by Pavelić; however, the Holy See did expressly repudiate the forced conversions in a memorandum dated 25 January 1942, from the Vatican Secretariat of State to the Yugoslavian Legation. The pope was well-informed of Catholic clergy involvement with the Ustaše regime, even possessing a list of clergymembers who had "joined in the slaughter", but decided against condemning the regime or taking action against the clergy involved, fearing that it would lead to schism in the Croatian church or undermine the formation of a future Croatian state. Pius XII elevated Aloysius Stepinac — a Croatian archbishop convicted of collaborating with the Ustaše — to the cardinalate. Phayer agrees that Stepinac's was a "show trial", but states "the charge that he [Pius XII] supported the Ustaša regime was, of course, true, as everyone knew", and that "if Stepinac had responded to the charges against him, his defense would have inevitably unraveled, exposing the Vatican's support of the genocidal Pavelić."
