1378 CE
At the Great Hall of the Conciergerie in Paris, King Charles V of France hosts the Banquet of the Three Kings with his uncle, Charles IV, Holy Roman Emperor and the Emperor's son, Wenzel the Idle, King of the Romans as his guests (along with 800 German and French knights), to celebrate the friendship between the nations. The banquet, held on the day of the Feast of the Epiphany, has three courses, with 10 dishes in each course. In England, John Wycliffe, who has been trying to promote ideas for Catholic reform and has published a tract outlining his theses, appears at the Church of St. Paul before a group of bishops headed by the Archbishop of Canterbury, Simon of Sudbury, to defend his actions. With a citation having directed him to appear "on the thirtieth court-day" after receipt, Wycliffe arrives before the bishops to proceed with trial, but proceedings are halted when Sir Lewis Clifford, dispatched by Joan of Kent, Princess of Wales, acting as the regent for her son, King Richard II the Kingdom, directs that the bishops are "not to presume to determine anything against John Wycliffe. According to a chronicler, "Struck with terror, they at once abandoned the business of their meeting," but they subsequently order Wycliffe to appear at Lambeth in March. Following the death of Pope Gregory XI, and riots in Rome calling for a Roman pope, the cardinals, who are mostly French, meet in a papal conclave and elect an Italian from Naples, Bartolomeo Prignano, Archbishop of Bari, as the 202nd Pope. Prignano takes the regnal name Pope Urban VI, and is the last Pope of the Roman Catholic Church to have been elected from outside of the College of Cardinals. The French cardinals then flee from Rome before the populace learns that a non-Roman was picked, and return to Avignon, beginning the Western Schism, a 39-year period where rival popes are selected at Avignon and Rome.
