50 free Popes trivia questions with answers — history quiz, new questions added Aug 2026.
Popes trivia for church history buffs, Conclave fans and anyone who watched the chimney in 2025 and wanted to know what the smoke meant. The quiz starts with the office itself: the Greek word for father, the Keys of Heaven, the titles from Supreme Pontiff to Servant of the Servants of God, the Fisherman's Ring that is cut in two when a pope dies, and the Lateran Treaty that created Vatican City in 1929. From there it covers how popes are made: the two-thirds majority, the age-80 cutoff for electors, the three-year deadlock at Viterbo that gave us the locked-in conclave, and 'Habemus Papam' from the balcony. Then the wild history: the seven French popes at Avignon, three rival popes at once during the Western Schism, the corpse put on trial at the Cadaver Synod, the legend of Pope Joan, the hermit who resigned after five months, the Borgias, the Warrior Pope who hired Michelangelo, and the pope who banned tobacco in a 12-day reign. Later questions cover infallibility, the longest and shortest reigns, why popes change their names, John Paul II's break with 455 years of Italians, Benedict XVI's resignation and Leo XIV, the first American pope. Questions run from easy to expert and every answer was checked against a reference page and carries its source. See also our Catholic Church, Vatican and Pope Francis quizzes.
