A chronological list of Popes in order from Pope Honorius III to Pope Boniface VIII, with many great portraits. Pope John XXI, from this time, is known as possibly the only Pope to have ever died from an accident. A newly built portion of his palace collapsed on him while he slept. Reigning from the Vatican as the head of the Roman Catholic Church and the Bishop of Rome, it is the Pope's divine duty to spread the gospel of Jesus Christ throughout the Holy See and interpret God's will so Catholics may enter Heaven's Kingdom. Many Popes achieved sainthood and are celebrated to this day.
