The leadership of the Catholic Church, including Pope Pius XII, his closest advisors, and many cardinals and bishops, was increasingly critical of the Nazi war crimes trials and the overall Allied denazification efforts following World War II. They viewed these actions as overly vengeful and instead positioned themselves as advocates for the vanquished, warning against the dangers of Communist expansion. By 1948, Pope Pius XII openly called for forgiving and forgetting Germany's wartime crimes, focusing instead on rebuilding the country. At the same time, papal organizations assisted Nazis and their collaborators in evading extradition and avoiding prosecution by fleeing overseas. The roles of individual clergymen such as Alois Hudal and Krunoslav Draganović in this context are well-documented, but other aspects remain understudied. This paper discusses the insights gained from archival records and initial research results. It also addresses the questions and challenges that remain in researching the Vatican's responses to Allied postwar justice efforts. At the center of the analysis are the worldviews, religious convictions, and political motivations of the Catholic clergy during the postwar years.
