For the country itself, see the Papal States.

The institution 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 provinces with at least 10 Development. 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).

Papacy can be disabled if the Papal States form the Kingdom of God, or if any orthodox nation restores the pentarchy.


The Curia Controller will gain the following bonuses:[1]

Yearly prestige.png +1% Yearly prestige
Stability cost modifier.png −10% Stability cost modifier

  • Can excommunicate Catholics before 1650
  • Can call crusades on non-Christians before 1650
  • Can break royal marriages without the -1 stability hit.


The Curia controller can excommunicate an enemy any time before 1650. 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 −2 Yearly prestige
  • Papal influence.png −10 Yearly papal influence
  • Yearly devotion.png −5 Yearly devotion
  • Tolerance of the true faith.png −3 Tolerance of the True Faith
  • Icon diplomacy relations.png -50 Relation with Catholic nations
  • Icon diplomacy relations.png -200 Relation with Catholic theocracies

Call a crusade

The Curia controller can also call a crusade against a single target any time before 1650. 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, controls at least 1 province owned by the crusade target and the Army Maintenance slider is at maximum. Crusades may no longer be called after 1650, but if a crusade called before 1650 hasn't expired yet, it will continue to stay in effect until 30 years have passed since its start, as before.

Crusade bonuses:

  • National manpower modifier.png +30% National manpower modifier

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 0.5 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
  • Development of candidate province must be at least 10
  • 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).

Cardinal acquisition

  • If you conquer a province with a cardinal - you get the cardinal.
  • There's an event where a cardinal can move from a province to an adjacent province and another event that allows you to gain a cardinal by gaining 0,5 corruption, spending money and having a 20% risk of having the relations worsend with the Pope ( Or to gain a Spymaster )

Papal influence

Papal influence is earned by all Catholic countries. A country can store at most 200 papal influence.[2] It can be spent in exchange for various benefits.
