The Catholic Church

  The existence of antipopes is one of the most unusual features of Church history. The first to be declared Pope, but be considered invalidly elected at the time or by history was St. Hippolytus, who disagreed with the Pope of the day but was later reconciled and died for the faith. Most antipopes have come about due to the intrigues of cardinals, secular princes or Roman nobility. ANTIPOPE (ALLEGED REIGN) ST.
