教宗国是被教宗控制的法理王国级领土 。教宗会对控制教宗国下的法理公国的统治者感到愤怒; 然后教宗可能会因为对你的低好感而开除你的教籍，这是值得天主教徒忧虑的一件事。相反，篡夺或销毁该头衔将极大地削弱教廷的世俗权力。
In considering your request, the Pope will consider your virtues and piety; opinion is only a minor factor. It also helps to have the same culture, same dynasty, a saintly bloodline, and influence over the College of Cardinals. Popes you supported in becoming cardinals and vassal popes are significantly more likely to accept your requests.

另一个例外是使用摧毁头衔的CB使得该头衔被摧毁时，例如部落入侵CB。只要一位东正教统治者控制着君士坦丁堡，普世牧首教座仍然可以通过一个决议得以恢复。This will grant both the bishopric and the top level holding of Constantinople to the new Patriarch, and grant him independence.（需要确认）
The Patriarchate has a unique mechanic of usurping their capital barony. The only requirement for this is that the bishopric in question is held by a character of the same religion as their head.
Upon doing so:
- they will receive the barony in question
- if the barony was the capital of a county, they will obtain the county title and all other baronies associated with it
- will become the vassal of the lowest-ranked ruler that can vassalize them
An example of the above: The Bishopric of Alexandria is currently held by a Coptic character. His lieges are, in order, the Count of Alexandria, the Duke of Alexandria, the King of Egypt, and the Emperor of Arabia, all different characters. (Their religion does not matter.) Once the Coptic Pope usurps the Bishopric of Alexandria from the current Bishop, he will become a vassal - however because Counts and Dukes cannot hold Dukes as vassals, he breaks the vassal contract with the Count of Alexandria and Duke of Alexandria and becomes the direct vassal of the King of Egypt, and consequently an indirect vassal of the Emperor of Arabia.
In a similar example with the Ecumenical Patriarch and Constantinople, he would instead be the direct vassal of the Emperor of Byzantium instead of the King of Greece, as Kings cannot vassalize Kings.
Note: You need to hold the title of either the Byzantine Empire or the Roman Empire to take this decision.
If all five seats of the pentarchy (Constantinople, Rome, Jerusalem, Alexandria, and Antioch) are controlled by Orthodox (or former Orthodox heresy) bishops who are all, along with the religious head, vassals (direct or indirect) of an independent ruler of the same religion, this liege has a decision to mend the Great Schism. This gives all Catholic characters the opportunity to convert to Orthodoxy and makes Catholicism and its heresies into heresies of Orthodoxy. This will not happen to Miaphysitism or Nestorianism, however, likely because these branches of Christianity broke off before the Great Schism. Please refer to the Decisions page for additional requirements to take this decision.
Iconoclasts, Paulicians, and Monothelites can also mend the schism if one of these heresies manages to replace Orthodoxy as the parent religion. Bogomilists, having no religious head, cannot mend the schism. Miaphysites, Nestorians, and their heresies, though they use the same mechanics as Orthodoxy, cannot mend the schism either.
Even though the Iconoclast, Paulician, and Monothelite Patriarchs can mend the Schism if they are no longer heretical, the Schism cannot be mended if the Pope (the bishop of Rome) has abandoned the Catholic faith for the Cathar, Fraticelli, Lollard or Waldensian heresies.
A Muslim religious head is known as a Caliph, a political and religious successor to the prophet Mohammad. Unlike Papacies and Patriarchates, which mainly hold religious authority and are usually regional secular powers at best, caliphates are often large feudal lands ruled by noble lords. This means one can play as the Caliph and call Jihads against enemy religions.
Caliphates are strongly tied to the primary title:
- When the primary title of a secular religious head is usurped, the religious head title is usurped as well. For example, taking the Arabian Empire may also make you the Sunni Caliph, as long as you are also Sunni.
- Characters of other religions are disqualified from the ruler's succession.
- Caliphates are destroyed if their holder becomes unlanded.
Muslim religious heads (including the Yazidi and Hurufi Sheikhs) gain access to two powerful CBs. You can use Caliphal Subjugation to take Kingdom-tier territories from rulers of the same religion, so long as you either border the kingdom or own land in it. (You retain the Muslim Invasion CB against everyone else.) You also have the ability to call Jihads every 30 years, which (upon success) both increase your religion's Moral Authority and potentially give you large amounts of land.
The disadvantages of being Caliph are minor. Your character's Diplomacy and Piety count for your religion's Moral Authority; if your character is impious or antisocial, you may have a hard time converting provinces, and heretics will pop up more often. The Caliphate or Sheikhdom counts as a duchy title, discouraging you from holding two de jure duchies. If your diplomacy and intrigue are both very low, you may be at risk of becoming known as a Wicked Caliph , which lowers moral authority. You also do not have access to the Give Sadaqah decision.
Caliphs cannot adopt another religion secretly.
A Muslim ruler who meets special requirements can create a caliphate for their branch of Islam.
- No caliph exists for this branch of Islam.
- Independent, or all lieges follow the same branch of Islam.
- For Shia: there is not an ongoing Shia caliphate revolt.
- For Shia, Sunni, Ibadi, or Hurufi:
- For Yazidi:
- 1000 Piety
- Control Mosul
- For Kharijite:
- 1000 Piety
- (Control Mecca and Medina) OR (control Jerusalem, Damascus, and Baghdad)
- For Qarmatian:
Players who meet all requirements will see a Title can be created alert. Players who are unsure which requirements are unmet can open the Religion tab, click the crown icon under "No Head", and hover the "Create Title" button.
Getting the Sayyid trait or a religious leadership bloodline into a dynasty requires matrilineal marriage. This is difficult because Muslims normally cannot marry matrilineally nor suggest matrilineal marriages. With Conclave DLC, matrilineal marriage becomes possible if you reach at least Notable Status of Women and then switch to a non-agnatic form of succession.
A Jew who restores the Kingdom of Israel and has built the Third Temple can, by decision, reinstate the office of Kohen Gadol, or High Priest. Like the Zoroastrian religious leader, the Kohen Gadol can call Great Holy Wars as soon as his office is reinstated.
With The Old Gods DLC, Zoroastrians can restore their ancient religion to prominence by retaking the Persian Empire and appointing a Moabadan-Moabad (Priest of Priests) who will function thereafter as a religious head. A notable feature of the Moabadan-Moabad is his ability to call Great Holy Wars without having to wait until the 11th or 12th century like Christians, Muslims or Reformed Pagans.
It is also possible with The Old Gods DLC to reform Pagan religions. The ruler who forms it and his direct vassals, demense, and courtiers will automatically convert, while other rulers have the option of conversion. This has the following effects:
- The old, unreformed religion has "old" in front of it, showing that it's the unreformed version, e.g. "Old Tengri". The old religion also becomes a heresy of the reformed religion.
- The religion becomes organised, getting a permanent +20% moral authority, which makes conversion of others easier and makes them less prone to conversion to other religions.
- The religion gets a head. This is a duke-tier vassal like an Orthodox Patriarch, except the Germanic Fylkir who is a secular ruler like the Muslim Caliphs. The leader can call Great Holy Wars (which are Crusades with a different name), so long as either the Christian Crusades or the Muslim Jihads are unlocked. Once a Great Holy War has been unlocked for one Pagan type, they are unlocked for all Pagan types.
- If the Player has the relevant DLC, the reformed faith gets a Holy Order. The Germanic Jomsvikings require The Old Gods, the Zunist Sun Warriors require Charlemagne, and all others require Sons of Abraham. (Note that the Jomsvikings may form on their own after the year 920, even if the faith is not reformed.)
- Rulers gain access to a modified Holy War casus belli, requiring 100 piety but having only a 5 year truce and usable against anyone of a different religion, including reformed and unreformed Pagans of a different religion.
- Rulers lose access to the Subjugation casus belli.
- Religions that get a defensive attrition bonus (all but Tengri and Aztec) lose it, but holdings keep their levy/garrison size and strength bonuses.
- (Without Conclave) Feudal rulers may set Crown Authority higher than Low.
- Tribal Pagan rulers do not receive opinion penalties from Reformed Pagan vassals, can have Gavelkind succession (along with Elective Gavelkind), and may settle to either feudalism or a Merchant Republic so long as they meet other requirements.
- Feudal rulers may use succession laws other than gavelkind (and ultimogeniture for Mongols), so long as they meet other requirements.
- Independence wars no longer have increased ticking warscore, making them harder to win. This is bad for vassals, but good for rulers.
- The "short reign" opinion penalty returns to its normal level (50% higher than other religions when unreformed).
- Germanic, Tengri, and Aztec rulers lose the prestige penalties for being at peace, but gain the usual opinion penalties for raising vassal levies.
It is possible to reform any of the Pagan religions except the generic Pagan and Hellenic religions. This requires 750 piety and either owning all five Holy Sites or owning three and having 50% moral authority.
Without Holy Fury, pagan reformation always creates a duke-tier religious head.
With Holy Fury, in order for the reformed pagan faith to have a religious head, the Leadership type chosen by the reformer must not be Autonomous. Also, with Holy Fury, Hellenism and the Bon faith can be reformed. The nature of the religious head depends on the leadership type.
Note that with Temporal, you cannot hold Temples without penalty unless you are reformed Bon with Monastic Feudalism. Temporal leadership also means that you are encouraged to act in a pious manner, as your piety directly affects the Moral Authority of the faith.
