Death of Pope Celestine IV, 179th successor of Peter who had been elected on October 28, 1241. The cardinals had been unable to reach an agreement on his election so the Roman Senate closed them under lock and key in the ancient palace of the Settizonio on the Coelian Hill. From this episode the Church derives the term "conclave."
Death of King Pedro III, monarch of Aragon who had wrongly been excommunicated by French sympathizing Pope Martin V.
