Antipope Benedict XIII in the context of "Avignon Pope"

The Avignon Papacy (Occitan: Papat d'Avinhon; French: Papauté d'Avignon) was the period from 1309 to 1376 during which seven successive popes resided in Avignon (at the time within the Kingdom of Arles, part of the Holy Roman Empire, now part of France) 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 agents of Philip IV of France. Following the subsequent death of Pope Benedict XI, Philip pressured a deadlocked conclave to elect the Archbishop of Bordeaux as pope Clement V 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 (cf. Italian cattività avignonese, i.e. "Avignonese captivity").

A total of seven popes reigned at Avignon, all French, and all under the influence of the French Crown. In 1376, Gregory XI abandoned Avignon and moved his court to Rome, arriving in January 1377. After Gregory's death in 1378, deteriorating relations between his successor Urban VI and a faction of cardinals gave rise to the Western Schism. This started a second line of Avignon popes, subsequently regarded as illegitimate. The last Avignon antipope, Benedict XIII, lost most of his support in 1398, including that of France. After five years besieged by the French, he fled to Perpignan in 1403. The schism ended in 1417 at the Council of Constance.

The Western Schism, also known as the Great Divide, the Great Occidental Schism, the Schism of 1378, or the Great Western Schism (Latin: Magnum schisma occidentale, Ecclesiae occidentalis schisma), was a split within the Catholic Church lasting from 20 September 1378 to 11 November 1417, in which bishops residing in Rome and Avignon simultaneously claimed to be the true pope, and were eventually joined by a line of Pisan claimants in 1409. The event was driven by international rivalries, personalities and political allegiances, with the Avignon Papacy in particular being closely tied to the French monarchy.

The papacy had resided in Avignon since 1309, but Pope Gregory XI returned to Rome in 1377. The Catholic Church split in September 1378, when, following Gregory XI's death and Urban VI's subsequent election, a group of French cardinals declared his election invalid due to intimidation and violence and, in the presence of three Italian cardinals, elected Clement VII, who claimed to be the true pope. As Roman claimant, Urban VI was succeeded by Boniface IX, Innocent VII and Gregory XII. Clement VII was succeeded as Avignon claimant by Benedict XIII.

Peter of Candia, also known as Peter Phillarges (Greek: Πέτρος Φιλάργης) (c. 1339 – 3 May 1410), denominated Alexander V (Latin: Alexander PP.V; Italian: Alessandro V), was an antipope elected by the Council of Pisa during the Western Schism (1378–1417). He invalidly reigned briefly from 26 June 1409 to his death in 1410, in opposition to the true 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 of the period as legitimate. The pontificate of Gregory XII was thus recognized to extend to 1415, and Alexander V was and is now recognized as an antipope.

The University of St Andrews (Scots: University o St Andras, Scottish Gaelic: Oilthigh Chill Rìmhinn; abbreviated as St And in post-nominals) is a public research university in the town of St Andrews in Scotland. It is the oldest of the four ancient universities of Scotland and, following the universities of Oxford and Cambridge, the third-oldest university in the English-speaking world. St Andrews was founded in 1413 when the Avignon Antipope Benedict XIII issued a papal bull to a small founding group of Augustinian clergy. Along with the universities of Glasgow, Aberdeen, and Edinburgh, St Andrews was part of the Scottish Enlightenment during the 18th century.

St Andrews is made up of a variety of institutions, comprising three colleges — United College (a union of St Salvator's and St Leonard's Colleges), St Mary's College, and St Leonard's College, the last named being a non-statutory revival of St Leonard's as a post-graduate society. There are 18 academic schools organised into four faculties. The university spans both historic and contemporary buildings scattered across the town. The academic year is divided into two semesters, Martinmas and Candlemas. In term time, over one-third of the town's population are either staff members or students of the university. The student body is known for preserving ancient traditions such as Raisin Weekend, May Dip, and the wearing of distinctive academic dress.

Pope Boniface IX (Latin: Bonifatius IX; Italian: Bonifacio IX; c. 1350 – 1 October 1404, born Pietro Tomacelli Cybo) was head of the Catholic Church from 2 November 1389 to his death, in October 1404. He was the second Roman pope during the Western Schism. In 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 Innocent VII (Latin: Innocentius VII; Italian: Innocenzo VII; 1339 – 6 November 1406), born Cosimo de' Migliorati, was head of the Catholic Church from 17 October 1404 to his death, in November 1406. He was pope during the period of the Western Schism (1378–1417), and was opposed by the Avignon claimant Benedict XIII. Despite good intentions, he did little to end the schism, owing to the troubled state of affairs in Rome, and his distrust of the sincerity of Benedict XIII, and King Ladislaus of Naples.

Pope Gregory XII (Latin: Gregorius XII; Italian: Gregorio XII; c. 1327 – 18 October 1417), 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.

The Council of Pisa (Latin: Concilium Pisarum; Italian: Concilio di Pisa, also nicknamed the conciliabolo, "secret meeting", by those who considered it illegitimate) was a controversial council held in 1409. It attempted to end the Western Schism by deposing both Benedict XIII (Avignon) and Gregory XII (Rome) for schism and manifest heresy. The College of Cardinals, composed of members from both the Avignon Obedience and the Roman Obedience, who were recognized by each other and by the Council, then elected a third papal claimant, Alexander V, who lived only a few months. He was succeeded by John XXIII.
