left Perpignan on 5 November. Because of this stubbornness, the Council of Constance declared Benedict a schismatic and excommunicated him from the Catholic Church on 27 July 1417, and elected Martin V as the new consensual pope on 11 November 1417. Benedict, who had lived in Perpignan from 1408 to 1417, now fled to the Peniscola Castle, near Tortosa, in the Kingdom of Aragon. He still considered himself the true Pope. His claim was now only recognised in the Kingdom of Aragon, where he was given protection by King Alfonso V. Benedict remained at Peñíscola from 1417 until his death there on 23 May 1423.

When, in 1429, an agreement between Rome and Aragon was reached, Clement VIII abdicated in favour of recognising Pope Martin V, terminating the Avignon line of anti-popes. In return, he was appointed as bishop of Majorca. Burials Benedict XIII was buried in Peniscola castle.
