An antipope (Latin : antipapa) is a person who, in opposition to the one who is generally seen as the legitimately elected Pope, makes a significantly accepted competing claim to be the Pope, [1] the Bishop of Rome and leader of the Roman Catholic Church. At times between the 3rd and mid-15th centuries, antipopes were supported by a fairly significant faction of religious cardinals and secular or anti-religious monarchs and kingdoms. Persons who claim to be pope, but have few followers, such as the modern sedevacantist antipopes, are not classified with the historical antipopes.

Pope leader of the Catholic Church

The pope, also known as the supreme pontiff, is the Bishop of Rome and ex officio leader of the worldwide Catholic Church. Since 1929, the pope has also been head of state of Vatican City, a city-state enclaved within Rome, Italy. The current pope is Francis, who was elected on 13 March 2013, succeeding Benedict XVI.

Diocese of Rome diocese of the Catholic Church in Rome, Italy

The Diocese of Rome is a diocese of the Catholic Church in Rome. The Bishop of Rome is the Pope, the Supreme Pontiff and leader of the Catholic Church. As the Holy See, the papacy is a sovereign entity with diplomatic relations, and civil jurisdiction over the Vatican City State located geographically within Rome. The Diocese of Rome is the metropolitan diocese of the Province of Rome, an ecclesiastical province in Italy. The first Bishop of Rome was Saint Peter in the first century. The incumbent since 13 March 2013 is Pope Francis.

A monarch is a sovereign head of state in a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Typically a monarch either personally inherits the lawful right to exercise the state's sovereign rights or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may become monarch by conquest, acclamation or a combination of means. A monarch usually reigns for life or until abdication.



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 [2] 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.

Hippolytus of Rome 3rd-century theologian in the Christian Church

Hippolytus was one of the most important second-third century Christian theologians, whose provenance, identity and corpus remain elusive to scholars and historians. Suggested communities include Palestine, Egypt, Anatolia, Rome and regions of the mideast. The best historians of literature in the ancient church, including Eusebius of Caesarea and Jerome, openly confess they cannot name where Hippolytus the biblical commentator and theologian served in leadership. They had read his works but did not possess evidence of his community. Photios I of Constantinople describes him in his Bibliotheca as a disciple of Irenaeus, who was said to be a disciple of Polycarp, and from the context of this passage it is supposed that he suggested that Hippolytus so styled himself. This assertion is doubtful. One older theory asserts he came into conflict with the popes of his time and seems to have headed a schismatic group as a rival to the Bishop of Rome, thus becoming an Antipope. In this view, he opposed the Roman Popes who softened the penitential system to accommodate the large number of new pagan converts. However, he was reconciled to the Church before he died as a martyr.

Pope Callixtus I Pope from 217 to 222

Pope Callixtus I, also called Callistus I, was the Bishop of Rome from c. 218 to his death c. 222 or 223. He lived during the reigns of the Roman Emperors Elagabalus and Alexander Severus. Eusebius and the Liberian catalogue gave him five years of episcopate (217–222). He was martyred for his Christian faith and is venerated as a saint by the Catholic Church.

Pope Pontian pope

Pope Pontian was Pope from 21 July 230 to 28 September 235. In 235, during the persecution of Christians in the reign of the Emperor Maximinus Thrax, Pontian was arrested and sent to the island of Sardinia. He resigned to make the election of a new pope possible.

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

Eusebius Greek church historian

Eusebius of Caesarea, also known as Eusebius Pamphili, was a historian of Christianity, exegete, and Christian polemicist. He became the bishop of Caesarea Maritima about 314 AD. Together with Pamphilus, he was a scholar of the Biblical canon and is regarded as an extremely learned Christian of his time. He wrote Demonstrations of the Gospel, Preparations for the Gospel, and On Discrepancies between the Gospels, studies of the Biblical text. As "Father of Church History", he produced the Ecclesiastical History, On the Life of Pamphilus, the Chronicle and On the Martyrs.

Christianity in the 3rd century Christianity-related events during the 3rd century

Christianity in the 3rd century was largely the time of the Ante-Nicene Fathers who wrote after the Apostolic Fathers of the 1st and 2nd centuries but before the First Council of Nicaea in 325.

Adoptionism theological teaching

Adoptionism, also called dynamic monarchianism, is a Christian nontrinitarian theological doctrine which holds that Jesus was adopted as the Son of God at his baptism, his resurrection, or his ascension.

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.

Novatian was a scholar, priest, theologian and antipope between 251 and 258. Some Greek authors give his name as Novatus, who was an African presbyter.

Pope Cornelius pope

Pope Cornelius was the Bishop of Rome from 6 or 13 March 251 to his martyrdom in 253. He was Pope during and following a period of persecution of the church and a schism occurred over how repentant church members who had practiced pagan sacrifices to protect themselves could be readmitted to the church. Cornelius agreed with Cyprian of Carthage that those who had lapsed could be restored to communion after varying forms of penance. That position was in contrast to the Novationists, who held that those who failed to maintain their confession of faith under persecution would not be received again into communion with the church. That resulted in a schism in the Church of Rome that spread as each side sought to gather support. Cornelius held a synod that confirmed his election and excommunicated Novatian, but the controversy regarding lapsed members continued for years.

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 Holy Roman Emperor was the ruler of the Holy Roman Empire during the Middle Ages and the early modern period. The title was, almost without interruption, held in conjunction with title of King of Germany throughout the 12th to 18th centuries.


An anti-king, anti king or antiking is a would-be king who, due to succession disputes or simple political opposition, declares himself king in opposition to a reigning monarch. The term is usually used in a European historical context where it relates to elective monarchies rather than hereditary ones. In hereditary monarchies such figures are more frequently referred to as pretenders or claimants.

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. The scandal of the Western Schism created anti-papal sentiment and fed into the Protestant Reformation at the turn of the 16th century.[ citation needed ]

Western Schism split within the Catholic Church from 1378 to 1417

The Western Schism, also called Papal Schism, Great Occidental Schism and Schism of 1378, was a split within the Catholic Church lasting from 1378 to 1417 in which two, since 1410 even three, men simultaneously claimed to be the true pope, having excommunicated one another. Driven by politics rather than any theological disagreement, the schism was ended by the Council of Constance (1414–1418). For a time these rival claims to the papal throne damaged the reputation of the office.

Pope Urban VI pope

Pope Urban VI, born Bartolomeo Prignano, was Pope from 8 April 1378 to his death in 1389. He is so far the last pope to be elected from outside the College of Cardinals. His reign, which began shortly after the end of the Avignon Papacy, was marked by immense conflict between rival factions as part of the Western Schism.

Antipope Clement VII Antipope

Robert of Geneva was elected to the papacy as Clement VII by the French cardinals who opposed Urban VI, and was the first antipope residing in Avignon, France. His election led to the Western Schism.

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). [7]

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. [8]

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, [9] but with the annotation: "Considered by some to be an antipope". Other sources classify him as an antipope. [10] [11]

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

Many antipopes created cardinals, known as quasi-cardinals, and a few created cardinal-nephews, known as quasi-cardinal-nephews.

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. [15]


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 allegedly faithful Catholics, none of whom was a cardinal:

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. [22] 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.


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.

Christopher held the (anti)papacy from October 903 to January 904. Although he was listed as a legitimate Pope in most modern lists of Popes until the first half of the 20th century, the apparently uncanonical method by which he obtained the papacy led to his being removed from the quasi-official roster of popes, the Annuario pontificio. As such, he is now considered an antipope by the Catholic Church.

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.
