Gregory IV of Naples

Gregory IV (died 915) was the firstborn son of Duke Sergius II of Naples and successor of his paternal uncle, Bishop Athanasius, in 898, when he was elected dux, or magister militum, unanimously by the aristocracy. His other paternal uncle, Stephen, succeeded Athanasius as bishop. According to the Chronicon ducum et principum Beneventi, Salerni, et Capuae et ducum Neapolis, he reigned for sixteen years and eight months. In 907 Gregory made a donation to the urban church of Saints Severinus and Sossus in Naples, which his forefathers had possibly founded.
