 In 1999, British author John Cornwell's Hitler's Pope criticised Pius XII for his actions and inactions during the Holocaust. Cornwell argued that Pius XII subordinated opposition to the Nazis to his goal of increasing and centralising the power of the Papacy. Further, Cornwell accused Pius XII of anti-Semitism. The Encyclopædia Britannica described Cornwell's depiction of Pius XII as anti-Semitic as lacking "credible substantiation". Kenneth L. Woodward stated in his review in Newsweek that "errors of fact and ignorance of context appear on almost every page." Paul O'Shea summarized the work by saying it was "disappointing because of its many inaccuracies, selective use of sources, and claims that do not bear any scrutiny. However, [Cornwell] has rendered a service by insisting Pacelli be re-examined thoroughly and placed firmly within the context of his times". Five years after the publication of Hitler's Pope, Cornwell stated: "I would now argue, in the light of the debates and evidence following Hitler's Pope, that Pius XII had so little scope of action that it is impossible to judge the motives for his silence during the war, while Rome was under the heel of Mussolini and later occupied by Germany".
