THE DEFINITIVE BIOGRAPHY OF THE FIRST AMERICAN POPE The Life, Teachings, Rise and Leadership Qualities of Pope Leo XIV. "Kengor’s deep understanding of both Catholicism and America make him the right scholar to introduce Americans to a deeper understanding of the first American Pontiff."—HON. NEWT GINGRICH From New York Times bestselling author and noted Catholic historian Dr Paul Kengor: A portrait of Robert Francis Prevost, his background and life, theological beliefs and teachings, relationship with his predecessors and fellow cardinals and clergy, and surprising rise to become the 267th elected Pontiff and first American Pope, and the challenges he will face and how he is likely to lead the Catholic Church, including interviews with Catholic and papal experts. In this first major biography of the new American pontiff, Editor of The American Spectator , chief academic fellow at the Institute for Faith & Freedom, professor of political science at Grove City College, historian and New York Times bestselling author of over twenty books, including A Pope and a President , The Divine Plan , and God and Ronald Reagan , Dr Paul Kengor delivers an engaging and gripping deep dive into the life and times of Robert Francis Prevost, whose election to the Chair of St. Peter on May 8, 2025, stunned the world. There had never been an American pope, and until this book, there has not been an in-depth examination of the new American pontiff and his extraordinary election. Professor Kengor takes readers on a spiritual sojourn from the very first pope, Peter, through the Medieval popes, through the turbulence of the Francis years, and through today’s pope and the figures who influenced him, from St. Augustine to Pope Leo XIII. He shows how this so-called “least American American” among the cardinals is actually quintessentially American, and yet also, remarkably, is quintessentially universal—ideally so for the head of the universal Roman Catholic Church. In this definitive biography, Dr. Kengor provides fascinating information on Prevost’s sudden rise from priest to bishop to cardinal and the inside story on how the vote went down in the Conclave, leading to the highly unexpected and yet overwhelming choice of Prevost on the fourth ballot. Kengor also provides a detailed treatment of the very revealing opening 40 days of Leo XIV’s pontificate and offers unique insights into where the world might expect the pope to proceed hereafter. The pope’s first word from the Loggia was “peace,” and he has committed himself to a mission of peace and unity for the Church and the wider world. If you want to get to know this mystery man who became pope—who became the first American pontiff—this is the book, a must-read for every Catholic and for non-Catholics as well. Praise for AMERICAN PONTIFF: Pope Leo XIV and His Plan to Heal the Church  by Paul Kengor, Ph.D. “Dr. Paul Kengor’s deep understanding of both Catholicism and America make him the right scholar to introduce Americans to a deeper understanding of the first American pontiff. As my wife Callista, who served as Ambassador to the Holy See, said, 'Pope Leo XIV is good for the Catholic Church and good for America.' Dr. Kengor has explained why she is right and why all of us should be excited that the Conclave picked Pope Leo XIV.” —HON. NEWT GINGRICH, former Speaker of the U.S. House of Representatives “Captures the drama that led to the election of the first American pope. Kengor is at his best in offering a biographical portrait of Leo; it gives us great insight into his thinking. His affection for Pope Leo XIII helps us to appreciate his mature understanding of social justice. This is more than a biography—Kengor knows how to tell a story. It is a story of a man whose holiness and humbleness was evident at a young age. While others sought to elevate themselves to the top, the man from Chicago never sought the limelight. We are fortunate that the world has now discovered him, and we are fortunate that Kengor illuminates his legacy with precision.” —BILL DONOHUE, PHD, President & CEO of the Catholic League for Religious and Civil Rights, and publisher of Catalyst “If you have been wondering (like most of the rest of the world) who Robert Prevost—AKA, Pope Leo XIV—is, you now have your answer, in a readable, intriguing and balanced treatment by Dr. Paul Kengor, who himself knows a thing or two about popes and Americans. This book will be a reference point for every Vaticanista for years to come.” —FATHER ROBERT SIRICO, President Emeritus of The Acton Institute “The election of American Robert Prevost as Pope Leo XIV shocked the world and raised many questions. Who is this man who now leads the Catholic Church? Why did the Cardinals choose him? What will be his agenda? How will he differ—or be the same as—his controversial predecessor Pope Francis? In American Pontiff: Pope Leo XIV and His Plan to Heal the Church , Dr. Paul Kengor ably addresses these questions and mor
