When Cardinal Eugenio Pacelli became Pope Pius XII in 1939, the Nazis had invaded Austria and Czechoslovakia and were poised to strike Poland. Jews and other minorities were already being sent to concentration camps, and the world was on the verge of another horrific war. The prevailing historical interpretation of the era was that Pius XII had a stated anti - Nazi and anti - Fascist policy; he tried to bring an end to the persecution and gave aid and comfort to those who were persecuted. Revisionist views, however, portray Pius XII as a silent, passive individual who ignored the treatment of Jews, Christians and other minorities - a man who could have stopped the holocaust and didn't. Through a series of articles and essays, the editor and eight contributors critique the works of revisionists who allege that Pius XII was sympathetic to the Nazis or unresistant to their atrocities. The essays discuss the roots of these views in the relentless Nazi and communist propaganda of the era, and the debate's revival after a 1960s stage play portrayed the pope as a leader afraid to speak out. By bringing intellectual rigor and responsibility to the issue, this work makes a solid contribution to the history of the papacy and to the biography of Pius XII.
