Benedict XIII, born Pedro Martínez de Luna, (1328 - May 23 1423), known as el Papa Luna in Spanish, was an Spaniard from Aragon, and is officially considered by the Roman Catholic Church to be an Antipope.

Benedict should not be confused with the Roman Pope Benedict XIII, who reigned from 27 May 1724 to 21 February 1730.

Early life

Pedro Martínez de Luna was born at Illueca, Aragon (part of modern Spain) in 1328. He belonged to the de Luna family, who were part of the Aragonese nobility. He studied law at the University of Montpellier, where he obtained his doctorate and later taught Canon law. His knowledge of canon law, noble lineage and austere way of life won him the approval of Pope Gregory XI, who appointed de Luna to the position of Cardinal Deacon of Santa Maria in Cosmedin on 30 December 1375.

Avignon election

In 1377 Pedro de Luna and the other cardinals returned to Rome with Pope Gregory, who had been persuaded to leave his papal base at Avignon by Catherine of Siena. After Gregory's death on March 27, 1378 the people of Rome feared that the cardinals would elect a French pope and return the papacy to Avignon. Consequently, they rioted and laid siege to the cardinals, insisting on an Italian pope. The conclave duly elected Bartholomew Prignani, Archbishop of Bari, as Urban VI on April 9, but the new pope proved to be intractably hostile to the cardinals. Some of them reconvened at Fondi in September 1378, declared the earlier election invalid and elected Robert of Geneva as their new pope, initiating the Western Schism. Robert assumed the name Clement VII and moved back to Avignon.

Pedro de Luna, a supporter of Clement throughout his reign, was unanimously elected by a conclave of twenty-four cardinals at Avignon on September 28 1394, following Clement's death on September 16. The conclave consisted of eleven French cardinals, eight Italians, four Spaniards and one from Savoy. On the death of Urban VI in 1389 the Roman College of Cardinals had chosen Boniface IX; the election of Benedict therefore perpetuated the Western Schism. At the start of his term of office, de Luna was recognised as pope by the kingdoms of France, Scotland, Sicily, Castile, Aragon, Navarre, and Portugal. In 1396 Benedict sent Sanchez Muñoz, one of the most loyal members of the Avignon curia, as an envoy to the Bishop of Valencia to bolster support for the Avignon papacy in Spain.

Decline of Avignon Papacy

However, in 1398 the French church withdrew its allegiance from the Avignon papacy. Benedict was abandoned by seventeen of his cardinals, with only five remaining faithful to him. An army led by Geoffrey Boucicaut, brother of the illustrious marshal, occupied Avignon and started a five year siege of the papal palace in 1398, which ended when Benedict managed to escape from Avignon on March 12, 1403 and seek shelter in territory belonging to Louis II of Anjou.

By this stage, Benedict's authority was no longer recognized in France, Portugal and Navarre, but he was acknowledged as pope in Scotland, Sicily, Aragon and Castile. After the Roman Pope Innocent VII died in 1406, the newly elected Roman pope, Gregory XII, started negotiations with Benedict, suggesting that they both resign so a new pope could be elected to reunite the Catholic Church. When these talks ended in stalemate in 1408, the French king, Charles VI, declared that France was neutral to both papal contenders. Charles helped to organise the Council of Pisa in 1409. This council was supposed to arrange for both Gregory and Benedict to resign, so that a new universally recognised pope could be elected. However, since both Benedict and Gregory refused to abdicate, the only thing that was achieved was that a third candidate to the Holy See was put forward: Peter Philarghi, who assumed the name Alexander V.

In part to bolster faltering support for his papacy, Benedict initiated the year-long Disputation of Tortosa in 1413, which became the most prominent Christian-Jewish disputation of the Middle Ages.

Benedict is also mentioned for his oppressive laws against the Jews. Those laws were repealed by Pope Martin V, after he received a mission of Jews, sent by the famous synod convoked by the Jews in Forlì, in 1418.

Council of Constance

In 1415 the Council of Constance brought this clash between papal claimants to an end. Gregory XII and Baldassare Cossa, who had succeeded Philarghi as the Pisan papal contender in 1410 and had assumed the name John XXIII, both agreed to resign. Benedict, on the other hand, refused to stand down, so he was declared a schismatic and excommunicated from the Catholic Church by the Council of Constance on July 27 1417. Benedict, who had lived in Perpignan from 1408 to 1417, now fled to the castle at Peñiscola near Valencia in Spain. He still considered himself the true pope, but his claim was now only recognised in the kingdom of Aragon, where he was given protection by King Alfonso V. Benedict remained at Peñiscola from 1417 until his death there on May 23, 1423.

Succession

The day before his death, Benedict appointed four cardinals of proven loyalty to ensure the succession of another pope who would remain faithful to the now beleaguered Avignon line. Three of these cardinals met on 10 June 1423 and elected Sanchez Muñoz as their new pope, with Muñoz assuming the papal name of Clement VIII. The fourth cardinal, Jean Carrier, the archdeacon of Rodez near Toulouse, was absent at this conclave and disputed its validity, whereupon Carrier, acting as a sort of one man College of Cardinals, proceeded to elect Bernard Garnier, the sacristan of Rodez, as pope, with Garnier taking the name Benedict XIV.

Burials

Benedict XIII was buried in Peñiscola castle. His body was later moved to Illueca; but during the War of the Spanish Succession his remains were destroyed. Only his skull was saved, and it rests in Condes de Argillo Palace in Aragón (Spain).

Miscellanea

The castle in Peñiscola where Benedict lived from 1417 until his death in 1423 was restored, improved and new walls were added in 1960 when Anthony Mann's film El Cid was partially filmed there. The town and castle of Peñiscola were playing the role of Valencia. The castle is now a popular tourist attraction.
The Anti-pope (Peter de Luna, 1342-1423) A study in obstinacy by Alec Glasfurd, Roy Publishers, New York (1965) B0007IVH1Q is a somewhat fictionalized or imaginative account of his life.
Pluja seca by Jaume Cabré (2001) is a play based on his death and succession.

The Spanish saying "seguir en sus trece" (to stay in his/her thirteen), meaning a stubborn behavior, refers to the obstinacy of Benedict and the numeral he adopted.
