Antipope Nicholas V

Nicholas V. (Pietro Rainalducci), antipope in Italy from 1328 to 1330 during the pontificate of Pope John XXII at Avignon. He was a native of Corbara[?] in the Abruzzi. He joined the Franciscan order after separating from his wife in 1310, and became famous as a preacher. He was elected through the influence of the excommunicated emperor, Louis IV the Bavarian, by an assembly of priests and laymen, and consecrated at St Peter's in Rome on May 12, 1328 by the bishop of Venice. After spending four months in Rome, he withdrew with Louis to Viterbo and then to Pisa, where he was guarded by the imperial vicar. He was excommunicated by Pope John XXII in April 1329, and sought refuge with Count Boniface of Donoratico[?] near Piombino. Having obtained assurance of pardon, he presented a confession of his sins first to the archbishop of Pisa, and then (August 25, 1330) to the pope at Avignon. He remained in honourable imprisonment in the papal palace until his death in October 1333.
