All Islamic denominations use the Piety Piety mechanic.

Piety is graded on a scale between −100 (mysticism) and +100 (legalism). Each side of the scale provides a different set of scaling bonuses while being in the center (0 piety) offers no bonus at all.

Mysticism.png Mysticism (maxed at −100 piety):[2]

Morale of armies.png +10% Morale of armies

Dhimmi loyalty equilibrium.png −10% Dhimmi loyalty equilibrium

A ruler's piety level can be affected by random piety events or through a more direct approach. These can either be religious conversions (increases), wars with heretics and heathens (increases by 25), wars with the same denomination (decreases by 16 or 33), and etc. Upon the ruler's death only a 1/4 of their piety score is inherited by the new ruler - this is to represent the differences in their religious devotion.

At 75 piety (negative or positive) it is possible to enact a special action providing a single bonus at the cost of moving the piety slider by 50 towards the center.

Action Effect Available at
Call on Religious Followers Call on Religious Followers Manpower.png +2 Yearly manpower Piety−75 Piety
Enforce Faithful Adherence Enforce Faithful Adherence Corruption.png −2 Corruption Piety+75 Piety

Certain countries have national ideas which move their piety rating on a monthly basis towards legalism (+) or mysticism ().

Muslim schools of law[edit]

There are 7 Islamic schools of law, each providing a bonus to the nation following it as well as affecting that nation's Icon diplomacy relations.png diplomatic relations with other Muslim nations.

Every Muslim nation adheres to one school of law. The school is predetermined (based on historical setting) and can't be changed by normal means during the campaign. Newly created nations or forcefully converted ones can choose any school to follow provided it is not excluded to their new denomination. Note that Ibadi Islam Ibadi nations are more flexible, with access to both Sunni and Shia Schools.

Diplomatic effects[edit]

The schools have a Icon diplomacy relations.png relationship with each other, ranging between respect, ambivalent and hate. While ambivalence grants no effect, nations from schools with a mutual respect or hatred will have their diplomatic ties strengthen or weaken respectively.

The relationships between the schools are affected by the actions of their followers. Members of differing schools involved in large scale, prolonged wars with each other will worsen relations. Alternatively, those nations having long and trusting alliances between them will improve the schools' relations. At the beginning of the campaign each school is ambivalent towards schools in its own group while hating schools from the other group.

Opinion modifiers resulting from Islamic schools of law include the following:

  • Opinion.png +10 Same religious school
  • Opinion.png −25 Religious school relation

In addition to this opinion modifier, AI-controlled nations also receive an acceptance modifier for an alliance.

  • +15 Same religious school
  • −15 Religious school relation

Invite a Scholar[edit]

A nation can Invite a scholar invite a scholar from a different school and gain that school's bonus (in addition to the one provided by their own school) for a duration of Time Icon.png 20 years.

The conditions for doing so require the inviting nation to have:

  • A nation which is either an ally, an overlord or a subject following the desired school.
  • Icon diplomacy relations.png +150 Relations with said nation
  • Piety−50 piety (if the school is excluded to the inviting nation's denomination).
  • Administrative power.png 50 Administrative power

It is impossible to have more than one foreign scholar at any given time. Inviting a scholar while one is already present will result in their replacement.
