 In March 1944 , through the papal nuncio in Budapest , Angelo Rotta , the pope urged the Hungarian government to moderate its treatment of the Jews . The pope ordered Rotta and other papal legates to hide and shelter Jews . These protests , along with others from the King of Sweden , the International Red Cross , the United States , and Britain led to the cessation of deportations on 8 July 1944 . Also in 1944 , Pius appealed to 13 Latin American governments to accept " emergency passports " , although it also took the intervention of the U.S. State Department for those countries to honor the documents . The Kaltenbrunner Report to Hitler , dated 29 November 1944 , against the backdrop of the 20 July 1944 Plot to assassinate Hitler , states that the Pope was somehow a conspirator , specifically naming Eugenio Pacelli ( Pope Pius XII ) , as being a party in the attempt .
