The Pope and Mussolini: The Secret History of Pius XI and the Rise of Fascism in Europe

Kertzer reconstructs a tense, consequential relationship between the Vatican and Mussolini’s fascist regime, showing how institutional power bargains with ideology. The book is built from deep archival research, including Vatican documents that illuminate backroom strategy. Kertzer writes with the momentum of political thriller while keeping the analysis historically grounded. Pius XI emerges as complex—capable of moral outrage, yet constrained by diplomacy and institutional interest. Mussolini’s opportunism is shown in chilling detail, as he uses religion for legitimacy. The narrative exposes how complicity can be incremental, rationalized step by step. Kertzer also highlights the human costs of these choices, including antisemitism and repression. The book challenges comforting narratives about moral clarity in times of authoritarian rise. It’s a study in the dangers of “pragmatism” when ethics are at stake. Readers come away with a sharper understanding of how fascism gains ground through alliances. A gripping, unsettling portrait of power and accommodation.
