The first one-volume history, based on the Vatican archives, of Pope Pius XII and his dealings with the contesting powers and with the Jews during World War II.

Filled with discoveries, this is the dramatic story of Pope Pius XII's struggle to response to the Second World War, the Holocaust, and the Nazi domination of Europe.The Pope at War is the third in a trilogy of books about Pope Pius XII's response to the rise of Fascism and Nazism. It tells the dramatic story of Pope Pius XII's struggle to respond to the Second World War, the Holocaust, and the ongoing Nazi attempts to exterminate the Jews of Europe. It is the first book dealing with the war to make extensive use of the newly opened Vatican archives for the war years. It is based, as well, on thousands of documents from the Italian, German,French, British, and American archives. Among the many new discoveries brought to light is the discovery that within weeks of becoming pope in 1939, Pius XII entered into secret negotiations with Hitler through Hitler's emissary, a Nazi Prince who was married to the daughter of the King of Italy and who was veryclose to Hitler. The negotiations were kept so secret that not even the German ambassador to the Holy See was informed of them. The book also offers new insight into the thinking behind Pius XII's decision to maintain good relations with the German government during the war, including keeping the Germans happy while they occupied Rome in 1943-1944. And throughout, David I. Kertzer shows the active role of the Italian Church hierarchy in promoting the Axis war while the pope, who as bishop ofRome was responsible for the Italian hierarchy, offered his silent blessings and cast his public speeches in such a way that both sides could claim support for their cause.

The “explosive” (The New York Times) bestseller that “redefined the history of the twentieth century” (The Washington Post ) This shocking book was the first account to tell the whole truth about Pope Pius XII's actions during World War II, and it remains the definitive account of that era. It sparked a firestorm of controversy both inside and outside the Catholic Church. Award-winning journalist John Cornwell has also included in this seminal work of history an introduction that both answers his critics and reaffirms his overall thesis that Pius XII fatally weakened the Catholic Church with his endorsement of Hitler—and sealed the fate of the Jews in Europe.

NEW YORK TIMES BESTSELLER • “The most important book ever written about the Catholic Church and its conduct during World War II.”—Daniel Silva “Kertzer brings all of his usual detective and narrative skills to [The Pope at War] . . . the most comprehensive account of the Vatican’s relations to the Nazi and fascist regimes before and during the war.”—The Washington Post “Tolstoyan.”—Cynthia Ozick Based on newly opened Vatican archives, a groundbreaking, explosive, and riveting book about Pope Pius XII and his actions during World War II, including how he responded to the Holocaust, by the Pulitzer Prize–winning author of The Pope and Mussolini WINNER OF THE JULIA WARD HOWE AWARD • LONGLISTED FOR THE PEN/JACQUELINE BOGRAD WELD AWARD • A NEW YORKER BEST BOOK OF THE YEAR When Pope Pius XII died in 1958, his papers were sealed in the Vatican Secret Archives, leaving unanswered questions about what he knew and did during World War II. Those questions have only grown and festered, making Pius XII one of the most controversial popes in Church history, especially now as the Vatican prepares to canonize him. In 2020, Pius XII’s archives were finally opened, and David I. Kertzer—widely recognized as one of the world’s leading Vatican scholars—has been mining this new material ever since, revealing how the pope came to set aside moral leadership in order to preserve his church’s power. Based on thousands of never-before-seen documents not only from the Vatican, but from archives in Italy, Germany, France, Britain, and the United States, The Pope at War paints a new, dramatic portrait of what the pope did and did not do as war enveloped the continent and as the Nazis began their systematic mass murder of Europe’s Jews. The book clears away the myths and sheer falsehoods surrounding the pope’s actions from 1939 to 1945, showing why the pope repeatedly bent to the wills of Hitler and Mussolini. Just as Kertzer’s Pulitzer Prize–winning The Pope and Mussolini became the definitive book on Pope Pius XI and the Fascist regime, The Pope at War is destined to become the most influential account of his successor, Pius XII, and his relations with Mussolini and Hitler. Kertzer shows why no full understanding of the course of World War II is complete without knowledge of the dramatic, behind-the-scenes role played by the pope. “This remarkably researched book is replete with revelations that deserve the adjective ‘explosive,’” says Kevin Madigan, Winn Professor of Ecclesiastical History at Harvard University. “The Pope at War is a masterpiece.”

An invaluable contribution to the history of the Catholic Church during the Second World War, this is a richly detailed eyewitness account of the life and politics of the Vatican by an American who worked there from 1940 to 1944. The question of whether Pius XII and the Vatican must bear blame for failing to act decisively in response to Hitler’s Final Solution is as hotly debated today as in the years directly following World War II. INSIDE THE VATICAN OF PIUS XII presents for the first time the observations of an American diplomat who spent four years inside the Vatican. This memoir of Harold H. Tittmann, Jr., describes his encounters with Pius XII and offers details that give a full picture of daily life in the Vatican. Writing of his own activities as a diplomat, Tittmann chronicles his role in assisting and hiding escaped prisoners of war and his experiences navigating the tensions with the representatives of enemy states, with whom he lived side by side. Deftly conveying the beauty and solemnity of events that took place in the dramatic settings of St. Peter’s, the Sistine Chapel, and the Pope’s private chapel, Tittmann’s work will be valued by historians and students of history for generations to come.

In this highly accessible work, José M. Sánchez offers a new approach to the controversy.
