Death of Saint Aldhelm, Benedictine English monk and Bishop of Sherborne who studied under Saint Adrian and founded numerous monasteries, supplanting the Celtic liturgical customs with the Latin liturgy in compliance with Rome.

Death of Saint Bede the Venerable, who also was a Benedictine monk in England and a learned man who specialized in English history and wrote an account of Christianity in Britain from the earliest times up to his time. He was dubbed "the Venerable" because of his wisdom and learning acumen. Unlike Aldhelm, he was named a Doctor of the Church in 1899 by Pope Leo XIII. He is said to be the first to date events using A.D. (anno Domini.
Death of Pope Saint Gregory VII, the 157th successor of Peter and a strong pontiff who excommunicated the Holy Roman Emperor Henry IV and lifted it only after Henry came on bended knee wearing a rough hewn habit of public penance in the bitter cold of northern Italy to seek a pardon.
Death of Pope Alexander IV, the 181st successor of Peter and the pope who canonized Saint Clare and confirmed the reality of the stigmata of Saint Francis of Assisi. It was something he was eminently qualified for since he had been Cardinal Protector of the Franciscans before his elevation to the papal throne.
Holy Roman Emperor Charles V, crowned by Pope Clement VII summoned the princes and bishops of Germany to a conference at Worms in Germany. In it they confronted Martin Luther and accused him of heresy and apostasy and demanded he recant. He refused and the group convened by Charles ordered Luther and his followers condemned and his writings burned and destroyed. This became the Edict of the Diet of Worms.
