Muslim denominationsEdit

ShiaEdit

Shia Muslims hold that the legitimate successor of the prophet Muhammad as Caliph and Imam was his cousin and son-in-law Ali. The Shiites believe that a number of Imams have followed Ali and still await the coming of his final successor.
In the game Shia Islam is present in Iran and Yemen and as the minority religion in some Indian Sultanates.

IbadiEdit

Ibadism is claimed by its adherents to be older than both Sunni and Shia Islam but is nowhere near as popular. The Ibadis stress strict adherence to an interpretation of Islam and the Sharia that they hold as both older and more orthodox.
In the game Ibadis exist in majority only in Oman, around the Mzab oasis area in North Africa and in Pate in East Africa.

PietyEdit

All Islamic denominations use the 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 (maxed at −100 piety):^[2]

	+10%	Morale of armies
	+3%	Missionary strength
	-10%	Idea cost
	+10%	Brahmins loyalty equilibrium
	−10%	Clergy loyalty equilibrium
	+10%	Dhimmi loyalty equilibrium

Legalism (maxed at +100 piety):^[3]

	−10%	Technology cost
	+20%	National manpower modifier
	+20%	National tax modifier
	−10%	Brahmins loyalty equilibrium
	+10%	Clergy loyalty equilibrium
	−10%	Dhimmi loyalty equilibrium

A ruler's piety level can be affected by random piety events or through certain decisions.

Upon the ruler's death piety is reset to 0.

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	×2 Yearly manpower	−75 Piety
	Enforce Faithful Adherence	−2 Corruption	+75 Piety

Certain countries have national ideas which move their piety rating on a monthly basis towards legalism (+) or mysticism (−). There are also some events and missions which give a monthly piety effect.

	Traditions	Ideas	Bonuses	Policies
+0.1	—	Banteni idea 1: Struck Down by Diamonds Hejazi idea 7: Successor to the Caliphate Tunisian idea 7: Tunisian Caliphate	—	Divine-Diplomatic: Faith Advisors
−0.1	—	Andalusian idea 4: Legacy of Ibn Arabi Ardabili idea 1: The Safavid Order Moroccan idea 2: Sufi Marabouts Mushasha idea 1: Fervent Millenarianism Shirvani idea 1: The Khalwati Order	—	—

Monthly piety acceleratorEdit

The Monthly piety accelerator effect on the other hand adds piety when above 0 and reduce it when below zero. This effect will always move you closer to the side you are already on. Stacking this effect can be used to repeatedly raise manpower or reduce corruption and generate money with debasing currency on the economy tab.

The fourth religious idea “Devoutness” gives +0.1 Monthly piety accelerator. The only other sources of that modifier are custom ideas and some monuments:

Name	Province	Noteworthy level	Significant level	Magnificent level
Great Mosque of Djenné	Jenne (1134)	+0.1 Monthly piety accelerator	+0.2 Monthly piety accelerator	+0.3 Monthly piety accelerator
Hagia Sophia	Constantinople (151)	N/A	+0.1 Monthly piety accelerator	+0.2 Monthly piety accelerator
Holy City of Kairouan	Kairwan (4566)	+0.1 Monthly piety accelerator	+0.2 Monthly piety accelerator	+0.3 Monthly piety accelerator
Imam Hussein and Al-Abbas Holy Shrines	Karbala (409)	+0.1 Monthly piety accelerator	+0.2 Monthly piety accelerator	+0.3 Monthly piety accelerator
Registan Square	Samarkand (454)	+0.1 Monthly piety accelerator	+0.2 Monthly piety accelerator	+0.3 Monthly piety accelerator
Taj Mahal	Central Doab (524)	+0.1 Monthly piety accelerator	+0.2 Monthly piety accelerator	+0.3 Monthly piety accelerator

With the Star and Crescent DLC, it is possible for a Muslim nation to unify Islam, representing the recreation of the Caliphate as it existed in medieval times.

Muslim schools of lawEdit

There are 7 Islamic schools of law, each providing a bonus to the nation following it as well as affecting that nation's 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 nations are more flexible, with access to both Sunni and Shia Schools.

School	Denomination
Hanafi	Sunni	−5%.0	Administrative technology cost
Hanbali	Sunni	−10%.0	Aggressive expansion impact
Maliki	Sunni	−10%.0	Development cost
Shafi'i	Sunni	+1.0%	Merchant
Ismaili	Shia	+1.0%	Yearly horde unity
		+1.0%	Yearly legitimacy
		+0.2%	Yearly republican tradition for Ismaili countries
		+0.5%	Yearly republican tradition for inviting an Ismaili scholar
		+1.0%	Yearly devotion
Jafari	Shia	+10%.0	Shock damage
Zaidi	Shia	−10%.0	Shock damage received

Diplomatic effectsEdit

The schools have a 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:

+10 Same religious school
−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 ScholarEdit

A nation can 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 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.
+150 Relations with said nation
−50 piety (if the school is excluded to the inviting nation's denomination).

This will cost 50 Administrative power, unless the Clergy privilege "Establish Religious Schools" is active.

Instead of inviting a scholar from another nation with good relations, the Clergy privilege "Grant local Residence to Scholar" grants permanent access to a scholar of a religious school of one's choice. The school can be changed every 20 years, at the cost of losing −25 piety.

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.
