(CNN) — “Conclave” the movie provides a gripping, if fictional, behind-the-scenes look inside the secretive election of a new pope. But last year’s real-life conclave was just as dramatic, with plenty of plot twists, political battles among cardinals and a surprise outcome.
A new book lifts a lid on how, in May 2025, Pope Leo XIV was elected as the first US-born pope in the Catholic Church’s 2,000-year history. Its authors tell in previously unheard detail how Cardinal Robert Prevost, a low-key Augustinian friar from Chicago, had quietly garnered support from fellow cardinals as the conclave got underway but remained under the radar of wider attention as a serious candidate.
Gerard O’Connell, the Vatican correspondent for “America,” a Catholic magazine based in New York, and Elisabetta Piqué, a correspondent for Argentina’s “La Nacion” newspaper and a CNN contributor at the 2025 conclave, describe how an Italian frontrunner faded from contention while providing a breakdown of the voting inside the Sistine Chapel. They also report how the election of Prevost caught many by surprise, including senior figures in the Vatican. For years, the prospect of an American pope had seemed impossible because of the “military, economic and cultural power” of the US, one cardinal told them.
O’Connell and Piqué, a husband-and-wife reporting team, were longtime friends of Pope Francis, who had baptized their two children in Argentina while still a cardinal there and later also married the couple.
The book, “The Election of Pope Leo XIV: The Last Surprise of Pope Francis,” draws on interviews with numerous cardinals.
Using those sources, the authors describe how in the tense days leading up to the conclave, a battle took place inside the College of Cardinals: Should they vote for a pope to continue the legacy and reforms of Francis, or make a course correction? As O’Connell and Piqué set out, with each contributing their own diary-style entries to the book, efforts to elect a pope who would go in a different direction to Francis were thwarted. Leo, while distinct in style from his predecessor and still somewhat inscrutable, could broadly be described as Francis’ choice.
Here are some of the takeaways from the new book.
A conservative won round one but then Leo emerged
The first ballot, O’Connell reports, saw Cardinal Péter Erdö, a Hungarian, gain the greatest number of votes. Erdö is a distinguished church lawyer and was the conservatives’ choice. While support for him was well-organized, it wasn’t necessarily widespread, O’Connell says. In that opening round, “more than 30 candidates got votes but only three received between 20 and 30,” he writes, with the other two contenders being Cardinals Robert Prevost and Pietro Parolin, the Holy See Secretary of State and leading Italian candidate. The next two ballots, however, saw support move swiftly to Prevost while Erdö’s dropped away. The first American pope was elected on the fourth ballot with 108 votes, with Parolin as runner-up, O’Connell says. The book also reveals the fourth ballot had to be repeated as one cardinal accidentally stuck two ballot papers together. (The same thing happened in the 2013 conclave).
Solemn, secret… but also human
The conclave is a serious, spiritual process in which the cardinals are cut off from the world – surrendering all electronic devices – before they cast their vote in front of the awesome fresco of Michelangelo’s “The Last Judgment.” But the book suggests not ev
