A 12-year papacy that placed a strong emphasis on charity, reform, and international outreach came to an end on April 21, 2025, when Pope Francis passed away at the age of 88.
As Catholics and the world at large grieve for the pope, his passing prompts contemplation of both his legacy and the remarkable individuals who have served as popes for centuries—some for decades—during the most pivotal periods in Church history.
From John Paul II’s dynamic leadership in the contemporary era to Saint Peter’s martyrdom in Rome, which started the uninterrupted line of succession, these long-reigning popes have guided the Church through periods of significant change.
