About the Author

David Israel Kertzer, Pulitzer Prize-winning author of The Pope at War: The Secret History of Pius XII, Mussolini, and Hitler, is a leading historian of Vatican politics and modern European religious conflicts. A professor of anthropology and Italian studies at Brown University, where he served as provost from 2006 to 2011, Kertzer specializes in uncovering the intersection of religion, power, and diplomacy through rigorous archival research.

His expertise stems from decades studying Italy’s political history, exemplified by his National Book Award-finalist The Kidnapping of Edgardo Mortara and The Pope and Mussolini, which earned the 2015 Pulitzer Prize for Biography and has been translated into 11 languages.

Kertzer’s works, including The Popes Against the Jews and Prisoner of the Vatican, blend scholarly precision with narrative-driven storytelling to dissect institutional power dynamics. A fellow of the American Academy of Arts and Sciences, his research has reshaped understanding of the Vatican’s role in 20th-century geopolitics.

The Pope at War, like its predecessor, draws on previously sealed archives to reveal how Pius XII navigated fascist alliances during World War II. Translated into multiple languages, Kertzer’s books are frequently cited in debates about religious ethics and authoritarianism, cementing his reputation as a definitive voice on papal history.

How does The Pope at War critique Pius XII’s response to the Holocaust?
