antipope, in the Roman Catholic Church, one who opposes the legitimately elected bishop of Rome, endeavors to secure the papal throne, and to some degree succeeds materially in the attempt. This abstract definition is necessarily broad and does not reckon with the complexity of individual cases. The elections of several antipopes are greatly obscured by incomplete or biased records, and at times even their contemporaries could not decide who was the true pope. It is impossible, therefore, to establish an absolutely definitive list of antipopes, but it is generally conceded that there were at least 37 from 217 to 1439. Felix V (1439–49) was the last.
Historically, antipopes have arisen as a result of a variety of causes; the following are some examples:
1. Doctrinal disagreement. The spread of Monarchianism (a Trinitarian heresy) led a Roman priest, Hippolytus, to try to replace Pope Calixtus I in the 3rd century. Hippolytus was later reconciled to Pope Pontianus during the persecution of Maximinus and died a martyr’s death in 235.

2. Deportation of the pope. The Arian emperor Constantius II exiled Pope Liberius for his orthodoxy in 355 and imposed the archdeacon Felix on the Roman clergy as Pope Felix II. Eventually, Liberius was allowed to return, and Felix lived in retirement until his death.
3. Double elections arbitrated by the secular authority. In 418 the archdeacon Eulalius was elected by a faction partial to him, and he was supported by the imperial prefect and the Byzantine court. The rest of the clergy, however, chose the priest Boniface I, who was eventually given official recognition by the emperor.
4. Double elections and subsequent recourse to a third candidate. In the 7th century Paschal and Theodore were rivals for the papacy, and both were unwilling to renounce their claims. Finally, a part of the community more inclined to moderation gained the papacy for Sergius I.
Somewhat similarly, in the 14th century the official residence of the papacy was moved to Avignon, France. This led to a schism (the Great Western Schism) beginning in 1378 that resulted in a papacy in Rome (regarded as canonical), a papacy in Avignon (regarded as antipapal), and eventually a third papacy established by the Council of Pisa (also regarded as antipapal). Unity was finally achieved by the election of Martin V on November 11, 1417.
5. Change in the manner of choosing the pope. In 1059 a new procedure for electing popes, proclaimed by Pope Nicholas II, deprived the German emperors of the leading role that they had played in earlier papal elections and also limited the influence of the Roman nobility. This led to the election of the antipope Honorius II in opposition to the canonically elected Alexander II, who was eventually recognized by the emperor. See also papacy and papal conclave.
List of popes and antipopes
A list of popes and antipopes of the Roman Catholic Church is provided in the table.
Popes and antipopes1 | |
---|---|
1Antipopes are in italics. Until the 4th century the popes were usually known only as bishops of Rome. | |
2The higher number is used if Felix (II), who reigned from 355 to 358 and is ordinarily classed as an antipope, is counted as a pope. | |
3Though elected on March 23, 752, Stephen (II) died two days later, before he could be consecrated, and thus is ordinarily not counted. The issue has made the numbering of subsequent Stephens somewhat irregular. | |
4Either Leo VIII or Benedict V may be considered an antipope. | |
5A confusion in the numbering of popes named John after John XIV (reigned 983–984) resulted because some 11th-century historians mistakenly believed that there had been a pope named John between antipope Boniface VII and the true John XV (reigned 985–996). Therefore they mistakenly numbered the real popes John XV to XIX as John XVI to XX. These popes have since customarily been renumbered XV to XIX, but John XXI and John XXII continue to bear numbers that they themselves formally adopted on the assumption that there had indeed been 20 Johns before them. In current numbering there thus exists no pope by the name of John XX. | |
6Sylvester III is considered an antipope by those who believe that Benedict IX's forcible removal in 1044 was illegitimate. | |
7In the 13th century the papal chancery misread the names of the two popes Marinus as Martin, and, as a result of this error, Simon de Brie in 1281 assumed the name of Pope Martin IV instead of Martin II. The enumeration has not been corrected, and thus there exist no Martin II and Martin III. | |
