An antipope 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, the Bishop of Rome and leader of the Catholic Church. At various times between the 3rd and mid-15th century, antipopes were supported by a fairly significant faction of religious cardinals and secular monarchs and kingdoms.
- Carius is the antipope elected by French cardinals in Oeufs, France, setting off the Grand Central Schism (Saint Fidgeta and Other Parodies, 58).
- Phobus IV is elected by four French cardinals and four Italian cardinals near Pisa in 1252 (Saint Fidgeta and Other Parodies; 58).
- Pirate Ragbash threatens city of Spug unless he is named pope; later succeeds through acclamation (Saint Fidgeta and Other Parodies, 59).
- All claimants come together and elect Zosimus II in Verona in May 1253 (Saint Fidgeta and Other Parodies, 59).
