Antipope

**Antipope** is a term of the Roman Catholic Church in the context of its official list of popes.  An antipope is not included in the list of popes in the Vatican's annual directory, _Annuario Pontificio_

An antipope is a pretender who falsely claims to be pope or who wrongly opposes the legitimate and recognized pope.

The existence or claims of an antipope produces a schism in the Roman Catholic Church.  A conflict is caused by those who are opposing the authority of the pope.
