For the country itself, see the Papal States.

The institute of the Papacy is the religious center of the Catholic faith, a moral authority for all Catholic nations. It is 'located' in the Papal States, but is separate from the country and will reform elsewhere if the country no longer exists. Cardinals now appear at random or appear via events in 5BT+ provinces. Each country can have at most, 7 cardinals. One nation is designated the current Papal Controller, also known as the Curia Controller, earning bonuses and able to use its power diplomatically (see below).
Do note that as Byzantium, the Papacy can be disabled when the Pentarchy is restored.


The Papal Controller will gain the following bonuses:


The Curia controller can excommunicate an enemy. This requires the enemy to be Catholic, and for the Papal States to have a negative opinion of the target. If the Papal States do not exist this requirement is waived and the Curia Controller can excommunicate any Catholic ruler. Excommunication gives every other Catholic nation a Casus Belli against them and increases yearly decay of prestige.

Excommunication Penalties

  • Yearly prestige.png Yearly Prestige : -2
  • (unrecognized string “tolerance” for Template:Icon) Tolerance of the True Faith : -3
  • Papal influence.png Yearly Papal Influence : -10
  • Icon diplomacy relations.png Relation with Catholic nations: -50
  • Icon diplomacy relations.png Relation with Catholic theocracies: -200

Call a crusade

The Curia controller can also call a crusade against a single target. This target must be a heathen and the Papal States must have an opinion of -50 of the target. Catholic nations that border the crusade target receive a Casus Belli against it, and all Catholic nations at war with the crusade target receive bonuses to manpower, morale, prestige and yearly papal influence while they are at war with them.

Crusade Bonuses:

  • National Tax Modifier Bonus : +10%
  • Morale of Armies : +10%
  • National Manpower Modifier : +30%
  • Yearly Prestige : +1
  • Yearly Papal Influence : +1

The Curia

The Curia is the administrative body of the Catholic Church overseen by a group of cardinals. There are 49 seats in the Curia, and a new cardinal will be inducted on the first day of each year should any seat be empty. New cardinals are randomly selected from among the Catholic provinces of Catholic nations. Cardinals are loyal to the Catholic ruler who has ownership of their province, so it possible to earn the allegiance of more cardinals through conquest. The primary benefit of controlling more cardinals is to increase one's papal influence. Per cardinal controlled, you gain .5 Papal Authority per year.

Cardinal selection

The top ten Catholic provinces in Catholic nations will compete for empty seats in the Curia. The chance of a cardinal being picked from any province can be seen in the tooltip over the Active Cardinals ribbon in the papacy interface. Factors that affect cardinal selection chance are as follows:

The Papacy
  • Provincial base tax of candidate province
  • Total provincial base tax of all Catholic provinces owned by nation (worth more)
  • Total provincial base tax of all non-Catholic provinces owned by nation (worth less)
  • Number of cardinals already controlled by nation

The selection of cardinals tends to favors countries whose wealth is concentrated in a few valuable provinces, rather than spread out over many poorer ones. Cardinals can only be elected from provinces on the same continent as the Papal States (usually Europe).

Papal influence

Papal influence is earned by all Catholic countries. A country can store at most 100 papal influence.[1] It can be spent in exchange for various benefits.

The change in papal influence is:

+0.5 yearly Base increase[2]
+0.5 yearly for each controlled Cardinal icon.png cardinal[3]
+1.0 yearly as Become Defender of the Faith.png defender of the Catholic faith[4]
+1.0 yearly for having the triggered modifier “Crusade[5]
−10.0 yearly during excommunication[5]
−10.0 yearly for having the triggered modifier “The Occupation of Rome[5]
−100.0 yearly as Revolution target.png revolution target[4]

Also the following ideas increase papal influence:

Additionally, implemented decisions and events can give gains or losses to papal influence.

The yearly change of papal influence is affected by the opinion of the Papal state towards a country, namely by 0.5% times this opinion.

yearly papal influence = Σ papal influence modifiers + 0.5% × opinion of the Papal state

Papal influence can be spent in the following manner:

Action Papal Influence Cost Effect
Invest influence 5 + 0.5 * current influence Gain +10 influence towards election of next Curia controller
