An antipope is a person who claims to be Bishop of Rome and leader of the Catholic Church in opposition to the legitimately elected pope. Between the 3rd and mid-15th centuries, antipopes were supported by factions within the Church itself and secular rulers.
Pope Boniface IX was head of the Catholic Church from 2 November 1389 to his death, in October 1404. He was the second Roman pope of the Western Schism. During this time the Avignon claimants, Clement VII and Benedict XIII, maintained the Roman Curia in Avignon, under the protection of the French monarchy. He is the last pope to date to take on the pontifical name "Boniface".
Pope Gregory XII, born Angelo Corraro, Corario, or Correr, was head of the Catholic Church from 30 November 1406 to 4 July 1415. Reigning during the Western Schism, he was opposed by the Avignon claimant Benedict XIII and the Pisan claimants Alexander V and John XXIII. Gregory XII wanted to unify the Church and voluntarily resigned in 1415 to end the schism.
Pope Urban VI, born Bartolomeo Prignano, was head of the Catholic Church from 8 April 1378 to his death, in October 1389. He was the most recent pope to be elected from outside the College of Cardinals. His pontificate began shortly after the end of the Avignon Papacy. It was marked by immense conflict between rival factions as part of the Western Schism, with much of Europe recognizing Clement VII, based in Avignon, as the true pope.
The Avignon Papacy was the period from 1309 to 1376 during which seven successive popes resided in Avignon rather than in Rome. The situation arose from the conflict between the papacy and the French crown, culminating in the death of Pope Boniface VIII after his arrest and maltreatment by Philip IV of France. Following the subsequent death of Pope Benedict XI, Philip forced a deadlocked conclave to elect the French Clement V as pope in 1305. Clement refused to move to Rome, and in 1309 he moved his court to the papal enclave at Avignon, where it remained for the next 67 years. This absence from Rome is sometimes referred to as the "Babylonian captivity of the Papacy".
The Western Schism, also known as the Papal Schism, the Great Occidental Schism, or the Schism of 1378, was a split within the Catholic Church lasting from 1378 to 1417 in which bishops residing in Rome and Avignon both claimed to be the true pope, and were joined by a third line of Pisan claimants in 1409. The schism was driven by personalities and political allegiances, with the Avignon papacy being closely associated with the French monarchy.
Pedro Martínez de Luna y Pérez de Gotor, known as el Papa Luna in Spanish and Pope Luna in English, was an Aragonese nobleman who, as Benedict XIII, is considered an antipope by the Catholic Church.
Guy de Malsec was a French bishop and cardinal. He was born at the family's fief at Malsec (Maillesec), in the diocese of Tulle. He had two sisters, Berauda and Agnes, who both became nuns at the Monastery of Pruliano (Pruilly) in the diocese of Carcassonne, and two nieces Heliota and Florence, who became nuns at the Monastery of S. Prassede in Avignon. He was a nephew of Pope Gregory XI, or perhaps a more distant relative. He was also a nephew of Pope Innocent VI. Guy was baptized in the church of S. Privatus, some 30 km southeast of Tulle. He played a part in the election of Benedict XIII of the Avignon Obedience in 1394, in his status as second most senior cardinal. He played an even more prominent role in Benedict's repudiation and deposition. Guy de Malsec was sometimes referred to as the 'Cardinal of Poitiers' (Pictavensis) or the 'Cardinal of Palestrina' (Penestrinus).
Jean de Murat du Cros was a French cardinal of the Catholic Church. He became the Bishop of Limoges (1347–1371). He was a leader in what became the Great Schism within Western Christianity.
The 1431 papal conclave convened after the death of Pope Martin V and elected as his successor Cardinal Gabriele Condulmer, who took the name Eugene IV. It was the first papal conclave held after the end of the Great Western Schism.
In the papal conclave held on 29 and 30 December 1370, after the death of Pope Urban V, Cardinal Pierre Roger de Beaufort was elected pope under the name Gregory XI. He thus became seventh and the last pope of the period of Avignon Papacy.
The selection of the Pope, the Bishop of Rome and Supreme Pontiff of the Catholic Church, prior to the promulgation of In Nomine Domini in AD 1059 varied throughout history. Popes were often putatively appointed by their predecessors or by political rulers. While some kind of election often characterized the procedure, an election that included meaningful participation of the laity was rare, especially as the Popes' claims to temporal power solidified into the Papal States. The practice of Papal appointment during this period would later result in the putative jus exclusivae, i.e., the claimed but invalid right to veto the selection that Catholic monarchs exercised into the twentieth century.
A papal conclave was held between 22 September and 28 October 1362 in the Palais des Papes of Avignon to elect the successor of Pope Innocent VI. Guillaume de Grimoard was elected pope and took the name Urban V.
Peter of Candia, also known as Peter Phillarges, named as Alexander V, was an antipope elected by the Council of Pisa during the Western Schism (1378–1417). He reigned briefly from 26 June 1409, to his death in 1410, in opposition to the Roman pope Gregory XII and the Avignon antipope Benedict XIII. In the 20th century, the Catholic Church reinterpreted the Western Schism by recognising the Roman popes, as legitimate. Gregory XII's reign was extended to 1415, and Alexander V is now regarded as an antipope.
In the 1303 papal conclave, Benedict XI was elected to succeed Boniface VIII as pope.
Pierre de Murat de Cros, O.S.B., was a French monk of aristocratic origins who became a cardinal of the Avignon Obedience during the Great Schism, as well as the Archbishop of Arles and the Chamberlain of the Apostolic Camera. Refusing from the day of his election to support Bartolomeo Prignano after the Papal Conclave of 1378, de Cros played a critical role in delivering a considerable portion of the Roman Curia to the rival claimant Robert of Geneva, who took the name Clement VII. Historian Daniel Williman calls Murat de Cros's actions a "counter-coup".
Robert of Geneva was elected to the papacy as Clement VII by the cardinals who opposed Pope Urban VI and was the first antipope residing in Avignon, France. His election led to the Western Schism.
Niccolò Brancaccio was born in the Kingdom of Naples, perhaps in Naples itself. He was Archbishop of Bari and then Archbishop of Cosenza, while serving in the Roman Curia in Avignon. He became a cardinal of the Avignon Obedience in 1378, and was Cardinal Priest of Santa Maria in Trastevere and then Cardinal Bishop of Albano. He participated in the Council of Pisa in 1409, and was one of the electors of Pope Alexander V and of Pope John XXIII.
Pierre Girard was born in the commune of Saint-Symphorien-sur-Coise, in the Department of Rhone, once in the ancient County of Forez. He died in Avignon on 9 November 1415. He was Bishop of Lodeve and then Bishop of Le Puy. He was a cardinal of the Avignon Obedience during the Great Western Schism, and was promoted to the Bishopric of Tusculum (Frascati). His principal work, however, was as a courtier and administrator at Avignon, and as a papal diplomat.
Giacomo Orsini, also spelled Jacopo Orsini, was a Roman prelate, the cardinal deacon of San Giorgio in Velabro from 1371 until his death shortly after the start of the Western Schism.
