An antipope (Latin : antipapa) is a person who, in opposition to the legitimately elected pope, makes a significant attempt to occupy the position of Bishop of Rome and leader of the Catholic Church. [1] At times between the 3rd and mid-15th centuries, antipopes were supported by important factions within the Church itself and by secular rulers.


Sometimes it was difficult to distinguish which of two claimants should be called pope and which antipope, as in the case of Pope Leo VIII and Pope Benedict V. [2]

Persons who merely claim to be pope and have few followers, such as the modern conclavist antipopes, are not classified with the historical antipopes.


Hippolytus of Rome (d.  235) is commonly considered to be the earliest antipope, as he headed a separate group within the Church in Rome against Pope Callixtus I. Hippolytus was reconciled to Callixtus's second successor, Pope Pontian, and both he and Pontian are honoured as saints by the Catholic Church with a shared feast day on 13 August. Whether two or more persons have been confused in this account of Hippolytus [3] and whether Hippolytus actually declared himself to be the Bishop of Rome, remains unclear, since no such claim by Hippolytus has been cited in the writings attributed to him.

Eusebius quotes [4] from an unnamed earlier writer the story of Natalius, a 3rd-century priest who accepted the bishopric of the Adoptionists, [5] a heretical group in Rome. Natalius soon repented and tearfully begged Pope Zephyrinus to receive him into communion. [6] [7]

Novatian (d. 258), another third-century figure, certainly claimed the See of Rome in opposition to Pope Cornelius, and if Natalius and Hippolytus were excluded because of the uncertainties concerning them, Novatian could then be said to be the first antipope.

The period in which antipopes were most numerous was during the struggles between the popes and the Holy Roman Emperors of the 11th and 12th centuries. The emperors frequently imposed their own nominees to further their own causes. The popes, likewise, sometimes sponsored rival imperial claimants (anti-kings) in Germany to overcome a particular emperor.

The Western Schism—which began in 1378, when the French cardinals, claiming that the election of Pope Urban VI was invalid, elected antipope Clement VII as a rival to the Roman Pope—led eventually to two competing lines of antipopes: the Avignon line (Clement VII took up residence in Avignon, France), and the Pisan line. The Pisan line, which began in 1409, was named after the town of Pisa, Italy, where the (Pisan) council had elected antipope Alexander V as a third claimant. To end the schism, in May 1415, the Council of Constance deposed antipope John XXIII of the Pisan line. Pope Gregory XII of the Roman line resigned in July 1415. In 1417, the council also formally deposed antipope Benedict XIII of Avignon, but he refused to resign. Afterwards, Pope Martin V was elected and was accepted everywhere except in the small and rapidly diminishing area that remained faithful to Benedict XIII.

List of historical antipopes

The following table gives the names of the antipopes included in the list of popes and antipopes in the Annuario Pontificio , with the addition of the names of Natalius (in spite of doubts about his historicity) and Antipope Clement VIII (whose following was insignificant). [8]

An asterisk marks those who were included in the conventional numbering of later popes who took the same name. More commonly, the antipope is ignored in later papal regnal numbers; for example, there was an Antipope John XXIII, but the new Pope John elected in 1958 was also called John XXIII. For the additional confusion regarding popes named John, see Pope John numbering.

The list of popes and antipopes in the Annuario Pontificio attaches the following note to the name of Pope Leo VIII (963–965):

At this point, as again in the mid-11th century, we come across elections in which problems of harmonising historical criteria and those of theology and canon law make it impossible to decide clearly which side possessed the legitimacy whose factual existence guarantees the unbroken lawful succession of the successors of Saint Peter. The uncertainty that in some cases results has made it advisable to abandon the assignation of successive numbers in the list of the popes. [9]

Thus, because of the obscurities about mid-11th-century canon law and the historical facts, the Annuario Pontificio lists Sylvester III as a pope, without thereby expressing a judgement on his legitimacy. The Catholic Encyclopedia places him in its List of Popes, [10] but with the annotation: "Considered by some to be an antipope". Other sources classify him as an antipope. [11]

As Celestine II resigned before being consecrated and enthroned in order to avoid a schism, Oxford's A Dictionary of Popes (2010) says he " classified, unfairly, as an antipope," [12] a position historian Salvador Miranda also shares. [13]

Those with asterisks (*) were counted in subsequent papal numbering.

Modern claimants to papacy

In modern times various people claim to be pope and, though they do not fit the technical definition of "antipope", are sometimes referred to as such. They are usually leaders of sedevacantist groups who view the See of Rome as vacant and elect someone to fill it. They are sometimes referred to as conclavists because of their claim, on the basis of an election by a "conclave" of perhaps half a dozen laypeople, as in the case of David Bawden ("Pope Michael I"), to have rendered the See no longer vacant. A significant number of these have taken the name "Peter II", owing to its special significance. From the point of view of the Catholic Church, they are schismatics, and as such are automatically excommunicated. [17]


Palmarian Catholic Church

The Palmarian Catholic Church regards Pope Paul VI, whom they revere as a martyr, and his predecessors as true popes, but hold, on the grounds of claimed apparitions, that the Pope of Rome is excommunicated and that the position of the Holy See has, since 1978, been transferred to the See of El Palmar de Troya.

Other examples

The following were elected by professedly faithful Catholics, none of whom were cardinals:

Antipope of Alexandria

As the Patriarch of Alexandria, Egypt, has historically also held the title of pope, a person who, in opposition to someone who is generally accepted as a legitimate pope of Alexandria, claims to hold that position may also be considered an antipope. In 2006, the defrocked married Coptic lector Max Michel became an antipope of Alexandria, calling himself Maximos I. His claim to the Alexandrine papacy was dismissed by both the Coptic Orthodox Pope Shenouda III and Pope Theodore II of the Greek Orthodox Church of Alexandria. [25] The Coptic pope of Alexandria and the Greek pope of Alexandria currently view one another, not as antipopes, but rather as successors to differing lines of apostolic succession that formed as a result of christological disputes in the fifth century.

Another Coptic (Alexandrian) antipope is known to have laid claim in the fourth century. His name was Gregory of Cappadocia.

In fiction

Antipopes have appeared as fictional characters. These may be either in historical fiction, as fictional portraits of well-known historical antipopes or as purely imaginary antipopes.

Antipope John XXIII Italian bishop; Pisan antipope (1410–1415)

Baldassarre Cossa was Pisan antipope John XXIII (1410–1415) during the Western Schism. The Catholic Church regards him as an antipope, as he opposed Pope Gregory XII whom the Catholic Church now recognizes as the rightful successor of Saint Peter.

Antipope Felix, was a Roman archdecon in the 4th century. He was installed as antipope from 355 to 365. Previously he was an archdeacon of Rome. He was installed irregularly in 355 after Emperor Constantius banished the reigned pope Liberius. Constantius, following the refusal of the laity to accept Felix attempted to have them co-rule but Felix was forced to retire. He was resented in his lifetime but has enjoyed a more popular memory since. Antipope, in the Roman Catholic church described any figure attempting to oppose the legitimately elected Bishop of Rome, with Felix being among the unsuccessful.

Pope Leader of the Catholic Church

The pope, also known as the supreme pontiff, the Roman pontiff or the Sovereign Pontiff, is the bishop of Rome, head of the worldwide Catholic Church and head of state or sovereign of the Vatican City State. According to Catholics, the primacy of the bishop of Rome is largely derived from his role as the apostolic successor to Saint Peter, to whom primacy was conferred by Jesus, giving him the Keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the church would be built. The current pope is Francis, who was elected on 13 March 2013.

Pope Gregory XII Claimant to the papacy during the Western Schism; Pope from 1406 to 1415

Pope Gregory XII, born Angelo Corraro, Corario, or Correr, was the Roman claimant to the headship of the Catholic Church from 30 November 1406 to 4 July 1415. Reigning during the Western Schism, he was opposed by the Avignon pope Benedict XIII and the Pisan popes Alexander V and John XXIII. Gregory XII was a very holy man who wanted the Church to be unified, and voluntarily abdicated in 1415 to end the Schism.

Pope Gelasius II, born Giovanni Caetani or Giovanni da Gaeta, was head of the Catholic Church and ruler of the Papal States from 24 January 1118 to his death in 1119. A monk of Monte Cassino and chancellor of Pope Paschal II, Caetani was unanimously elected to succeed him. In doing so he also inherited the conflict with Emperor Henry V over investiture. Gelasius spent a good part of his brief papacy in exile.

Pope Nicholas II, otherwise known as Gerard of Burgundy, was the head of the Catholic Church and ruler of the Papal States from 24 January 1059 until his death. At the time of his election, he was bishop of Florence. During his Papacy, Nicholas II successfully expanded the influence of the papacy in Milan and southern Italy. He was also responsible for passing papal election reforms which resulted in greater papal influence in electing new Popes.

Western Schism Split within the Catholic Church from 1378 to 1417

The Western Schism, also called Papal Schism, The Vatican Standoff, Great Occidental Schism and 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, joined by a third line of Pisan popes in 1409. The schism was driven by personalities and political allegiances, with the Avignon papacy being closely associated with the French monarchy. These rival claims to the papal throne damaged the prestige of the office.

Benedict XIV was the name used by two closely related minor antipopes of the 15th century. The first, Bernard Garnier became antipope in 1424 and died c. 1429. The second, Jean Carrier, became antipope c. 1430 and apparently left office, whether by death or resignation, by 1437.

Gregory VIII, born Mauritius Burdinus, was antipope from 10 March 1118 until 22 April 1121.

Adalbert was elected pope of the Catholic Church in February 1101 and served for 105 days. He was a candidate of the Roman party opposed to Pope Paschal II and is regarded today as an antipope. Prior to his election he was created a cardinal by the antipope Clement III. He was captured by partisans of Paschal II and forced to live out his days as a monk.

A papal renunciation occurs when the reigning pope of the Catholic Church voluntarily steps down from his position. As the reign of the pope has conventionally been from election until death, papal renunciation is an uncommon event. Before the 21st century, only five popes unambiguously resigned with historical certainty, all between the 10th and 15th centuries. Additionally, there are disputed claims of four popes having resigned, dating from the 3rd to the 11th centuries; a fifth disputed case may have involved an antipope.

Antipope Benedict XIII Antipope from 1328 to 1423

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.

Antipope Paschal III was a 12th-century clergyman who, from 1164 to 1168, was the second antipope to challenge the reign of Pope Alexander III. He had previously served as Cardinal of St. Maria.

<i>Annuario Pontificio</i> Catholic Holy See annual directory

The Annuario Pontificio is the annual directory of the Holy See of the Catholic Church. It lists the popes in chronological order and all officials of the Holy See's departments. It also provides names and contact information for all cardinals and bishops, the dioceses, the departments of the Roman Curia, the Holy See's diplomatic missions abroad, the embassies accredited to the Holy See, the headquarters of religious institutes, certain academic institutions, and other similar information. The index includes, along with all the names in the body of the book, those of all priests who have been granted the title of "Monsignor".

Papal name Regnal name taken by a pope

A papal name or pontificial name is the regnal name taken by a pope. Both the head of the Catholic Church, usually known as the pope, and the pope of the Coptic Orthodox Church of Alexandria choose papal names. As of 2013, Pope Francis is the Catholic pope, and Tawadros II or Theodoros II is the Coptic pope. This article discusses and lists the names of Catholic popes; another article has a list of Coptic Orthodox popes of Alexandria.

Conclavism is the claim to election as pope by a group acting or purporting to act in the stead of the established College of Cardinals. This claim is usually associated with the claim, known as sedevacantism, that the present holder of the title of pope is a heretic and therefore not truly pope, as a result of which the faithful remnant of the Catholic Church has the right to elect a true pope.

1119 papal election

The 1119 papal election was, by an order of magnitude, the 12th century's smallest papal election that is currently considered legitimate by the Roman Catholic Church.

The numbering of "popes John" does not occur in strict numerical order. Although there have been twenty-one legitimate popes named John, the numbering has reached John XXIII because of two errors that were introduced in the Middle Ages. First, antipope John XVI was kept in the numbering sequence instead of being removed. Then, the number XX was skipped because pope John XXI counted John XIV twice.
