Information about Pope Alexander V (Anti-pope)

Peter of Candia or Peter Phillarges ruled as Alexander V (Latin: Alexander PP. V, Italian: Alessandro V) and was an antipope during the Western Schism (1378–1417). He reigned from June 26, 1409, to his death in 1410 and is officially regarded by the Roman Catholic Church as an antipope.

At the Council of Pisa (from March 25, 1409), the assembled cardinals chose Philarges as the new prelate for a chair they presumed was vacant. He was crowned on June 26, 1409, as Alexander V, making him in reality the third rival pontiff. Following his election, most polities in Europe recognised him as the true pontiff with the exceptions of the Kingdom of Aragon and Scotland, which remained loyal to the Avignon pope, and various Italian states, which adhered to the Roman pope.

During his ten-month reign, Alexander V's aim was to extend his obedience with the assistance of France, and, notably, of Duke Louis II of Anjou, upon whom he conferred the investiture of the Kingdom of Sicily, having removed it from Ladislaus of Naples. He proclaimed and promised rather than effected a certain number of reforms: the abandonment of the rights of "spoils" and "procurations," and the re-establishment of the system of canonical election in the cathedral churches and principal monasteries. He also gave out papal favours with a lavish hand, from which the mendicant orders benefitted especially.

Alexander V suddenly died while he was with Cardinal Baldassare Cossa at Bologna, on the night of 3–4 May 1410. His remains were placed in the church of St. Francis at Bologna. A rumour, though now considered false, spread that he had been poisoned by Cossa, who succeeded him as John XXIII.

Alexander V is still numbered with subsequent popes since his official status as an antipope was not asserted until the 20th century. Because of this Rodrigo Borgia took the name Pope Alexander VI in 1492.
