Crusades, Jihads and Great Holy Wars
When the religious head calls a crusade, all rulers will be notified and all rulers of the attacking religion will be pressured to join the war effort. The vassals of any independent ruler will get a relations penalty with their liege if the ruler chooses not to join the crusade, and this penalty is even larger with the clergy. The penalty disappears upon joining the crusade, and is replaced with a bonus.
By leading troops within the crusade target, characters can gain a religion-specific trait that improves martial skill and give permanent opinion bonuses with all clergy and other characters who share the trait. For example, Christians who arrive in the target kingdom can gain the Crusader trait. By swapping army commanders, you can ensure that your direct vassals and heirs gain the trait as well.
If the war is won, rulers of the attacking religion within the kingdom's de jure borders, and all rulers outside the de jure borders but within the de facto borders, are vassalized; all other titles are usurped. What happens with the seized land depends on the status of the kingdom title.
- If the relevant kingdom exists and the title holder is of the same religion as the attackers, he receives all seized titles.
- If there is no same-faith holder, the land will be given to a claimant determined by the strength of the claim and the claimant's participation in the Crusade.
- Otherwise, whoever participated the most will gain the kingdom. Participation, as with other wars, is calculated by troops thrown into battle and the capturing of territory. If the victor is vassal to a king or below, they will become independent. If the target was Jerusalem, a Catholic victor might be compelled to give it up to the Knights Templar, which provides a large amount of piety.
If the targeted kingdom does not exist, it is created for free and given to the victor.
If the holder of the kingdom is not of the religion of the attackers but is involved in wars besides the crusade, the kingdom title will not be granted, though all vassal titles will. Once the holder is not at war, it can be usurped.
Note that new mechanics have been added to Catholic/Fraticelli crusades with Patch 3.0, thus distinguishing them from other GHWs.
Differences by religion
The casus belli for all the religions is the same, but has a different name and are called by a different character depending on the attacker's religion:
- It is a Crusade for:
- Catholic (Pope)
- Fraticelli (Pope)
- It is a Jihad for:
- Sunni (Caliph)
- Shiite (Caliph)
- Ibadi (Caliph)
- Yazidi (Sheikh)
- Hurufi (Sheikh)
- Kharijite (Caliph)
- It is a Great Holy War for:
- Zoroastrian (Moabadan-Moabad)
- Jewish (Kohen Gadol)
- Reformed Germanic (Fylkir)
- Reformed Romuva (First Vaidila)
- Reformed Slavic (Chernoban)
- Reformed Suomenusko (Tietaja)
- Reformed Tengri (Tengrikut)
- Reformed African (Grand Saltigue)
- Reformed Aztec (Tlatoani)
- Reformed Zunist (Dastur)
- Reformed Bön (Dalai Lama)
- Reformed Hellenic (Pontifex Maximus)
The following religions do not have a crusade equivalent:
- Cathar, Lollard, Waldensian
- Orthodox and its heresies
- Miaphysite and its heresies
- Nestorian and its heresies
- Mazdaki, Manichean
- Samaritan, Karaite
- Pagan (generic)
All religions can call crusades against infidels, heretics of the religion, or the parent religion (for heretics). Additionally, the Fylkir and the High Priests can declare Great Holy Wars on Pagans not of the same religion. Caliphs, however, cannot declare Jihads against Muslims of other denominations, unlike Holy Wars. If the Great Schism has been mended, neither the Catholic nor Fraticelli Popes can call Crusades.
Unlocking Great Holy Wars
Great Holy Wars become available to different religions depending on certain criteria. For instance, Catholic crusades will start by default in the late 11th century (as they did historically), but they can be called earlier if key Christian sites are in danger (based on the religion of the top liege). However, no Crusades or Jihads will ever start before 900 AD. Rulers of other religions should avoid triggering early Crusades as many Catholic holy orders are found at the same time, allowing pious Catholic rulers to hire troops for their defence against heretics and infidels.

When playing from an alternate start with randomized religion names, GHWs are instead unlocked when the year is at least 1100 and there are at least five independent landed king+ rulers.
Requesting a Great Holy War (GHW)
A religious head can call a GHW if:
- The religion's GHW has been unlocked
- The religion has not had a GHW end in the last 30 years
- Hover the religion icon on any character screen to see when their religion can next call a GHW
- Moral authority > 5%
- Catholic/Fraticelli cannot call Crusades if the Schism has been mended
- Catholic/Fraticelli popes cannot declare another crusade within 10 years of personally cancelling a Crusade for insufficient pledges (?)
- During a regency, their council must approve. The council always approves Christian crusades.
The target for the GHW must meet the following criteria:
- Target is infidel, or heretic vs parent religion, or pagan vs any
- Target is not a revolt
- Target controls at least 6 counties in the selected de jure kingdom
A ruler can request a GHW if:
- At peace
- Not at war with religious head
- Does not have an antipope
- Not a vassal of target realm
- No truce with target realm
- Can spend 500 piety
- Only Christians can request crusades (?)
- The option will seemingly not appear if the Pope has any raised levies, personal or realm(?).
Players can request crusades by right-clicking on an independent ruler, selecting "Request Crusade", and then selecting one of the kingdoms controlled by the ruler. If the Pope is a vassal, the liege has to allow external Vassal Wars for the option to appear.
Patch 3.0 Crusades
With patch 3.0 installed, crusades begin two years after the date the Pope calls them. Rulers can pledge themselves to the crusade either at the announcement, or at any point during the next two years, after which they will be obligated to declare war on the defending realm when the crusade begins. They can retract the pledge at any point, but doing so will incur a relations drop with the Pope. During the two year waiting period, the player can spend piety to change the target of the crusade, and participating rulers can donate gold and artifacts to a war chest.
On a victorious crusade, the contents of the war chest, along with land and titles, will be granted to the participants of the crusade based on their war contribution.
Each participant is encouraged to select a dynasty member as their crusade beneficiary. Beneficiaries must be:
- A member of the ruler's dynasty
- At least 12 years old
- Not the heir to a title
The beneficiary of the highest contributor will get the kingdom title. The kingdom recipient also gains the Crusader King trait, giving +35 same religion opinion and other benefits, but disqualifying them from most elections. In the First Crusade only, the recipient also founds the Crusade Lord bloodline.
Beneficiaries of other contributors will be given lower titles (duchies, counties, minor castles) in order of contribution. All beneficiaries who gain titles gain a flag that ensures all dynasty members gain +1 monthly piety during their lifetime.
Players have the option to take the titles for themselves instead of for a beneficiary. However, selecting such a self-serving stance incurs a -20 opinion penalty with the Pope for the next 20 years, which will not go away if the player changes their stance.
Cancellation of a Crusade
When the time comes to crusade (about 2 years after the date the Pope calls it), if the relative strength of all participants of the upcoming crusade is less than 75% of all those supporting the target, the Pope will be very disappointed and cancel the crusade. As the Pope blames everyone for faithlessness, everyone will lose 100 piety. In addition to that, a new crusade cannot be called for a period of time. The religion of the Pope who called the crusade (Catholic or Fraticelli) will lose 10% MA for 10 years.
During a crusade, if you are at least a duke and you occupy all the titles of a duchy that is not part of the kingdom target by the crusade (for example, if the crusade is for Jerusalem and you siege a duchy in Egypt or Syria), you can take a title decision (click on the crest of the province you want to be the new state's capital) and form the crusader state. You can decide to incorporate the state into your kingdom, abdicate your throne to rule over the new state or put your Crusade Beneficiary in charge (you can then play as the Crusade Beneficiary).
- have at least 500 prestige
- have at least 300 gold
- occupy all of the DeJure Counties of the duchy
- have a Crusade beneficiary or someone who has the potential to become a Crusade Beneficiary
- the duchy must be coastal or neighbor a non-heretical Christian
- all the DeJure County title owners are fighting the Crusade
- the duchy must not be the target of the Crusade
- none of the DeJure County titles are held by the Crusade target or its vassals
GHW target weight
Below is a list of weights for various titles for each religion. Religious heads will usually call GHWs on the title with the highest weight that is not controlled by their religion. For example, the Catholic Pope will usually call a crusade for Italy rather than Jerusalem if both are held by non-Christians.
