The popes, likewise, sometimes sponsored rival imperial claimants ( anti-kings) in Germany to overcome a particular emperor. The emperors frequently imposed their own nominees to further their own causes.

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. 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. Natalius soon repented and tearfully begged Pope Zephyrinus to receive him into communion. Whether two or more persons have been confused in this account of Hippolytus 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.Įusebius quotes from an unnamed earlier writer the story of Natalius, a 3rd-century priest who accepted the bishopric of the Adoptionists, a heretical group in Rome. 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. 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.
