Gregory V Bruno—the future Pope Gregory V—was a younger son of Otto of Worms. His father's cousin, Otto III, placed him on the papal throne in 996, ignoring the provisions of his own Diploma Ottonianum on papal elections. Bruno, who was the first German pope, assumed his papal name in memory of Pope Gregory the Great. He crowned Otto III emperor on the Feast of the Ascension in the same year. The Roman aristocrat Crescentius the Younger expelled him from Rome, but the Emperor crushed the revolt and restored the papal throne to Gregory V.
