Yazidi (Sunni): Caliph (Sheik) and Jihads.

Iqta rulers can freely revoke duchies, and use Open succession to effectively designate heirs. Iqta government replaces both Feudal and Theocracy governments, allowing rulers to hold both castles and mosques without penalty. All faiths of Islam (but not all heresies) can have a Caliph, a secular (and thus playable) religious head who can declare Jihads. Powerful Muslim CBs allow fast expansion, but large realms often fail due to dynastic decadence.

Completely control the Kingdom of Jerusalem and convert the county of Jerusalem to Judaism in order to create the Kingdom of Israel and restore the High Priesthood.

Samaritan/Karaite: two heresies without special mechanics.

However, a unique requirement for instating the religious head is to convert the county of Jerusalem to Judaism. If the High Priesthood is restored, Jewish Great Holy Wars can be declared immediately.

Miaphysite and Nestorian: reclaim the holy sites of your faith of which the majority are occupied by strong Muslim realms.

Byzantine Empire: Completely control key duchies in order to restore the Roman Empire.

Orthodox: Control the five Pentarchy sites to Mend the Great Schism.

Catholic, any start: reconquer and then defend the Catholic holy sites and heartlands, especially via Crusades.

Catholic, later: hold Germany to Restore the Holy Roman Empire.

Catholic, 769 start: hold Italy (or Italia) as one of the requirements to Create the Holy Roman Empire.

Messalian (Nestorian): full equality like Cathar close-relative marriage like Zoroastrians.

Bogomilist (Orthodox): female temple holders, no penalty for female rulers/heirs.

Cathar (Catholic): full equality (allows female temple holders, councillors, and commanders no opinion penalty for female ruler or heir, enables Absolute Cognatic succession law).

Fraticelli (Catholic): can establish a papacy with a pope just like Catholicism, Fraticelli pope can then declare Crusades as well.

Nestorian: a once-major branch of Christianity, led by Patriarch of the East.

Miaphysite: a branch of Christianity in East Africa, led by Coptic Pope of Alexandria.

Orthodox: the largest religion with autocephaly.

More opportunities to use Sanctioned Invasion CB. extra Papal favors, Papal succession by election among the College of Cardinals, antipopes, investiture. Relations with religious head are important, as they can perform excommunication, enabling free imprisonment and a depose-ruler CB. Variants of Christianity are uniquely peaceful toward each other, disallowing the use of religious revocation except against heretics. None (all Christian faiths part of core game) Within each group there are variants, heresies, or both. Six religious groups are represented in Crusader Kings II.
