{{version|2.8}}
'''穆斯林'''（英文'''Muslims'''）意为'''伊斯兰教'''（英文'''Islam'''）的信徒，《王国风云2》中六大[[religion|宗教组]]之一。在{{icon|soi}} ''[[伊斯兰之剑]]'' DLC激活后，玩家可以扮演非游牧政体的穆斯林统治者。
伊斯兰教拥有许多其他[[宗教]]没有的机制，需要特殊的策略。一般来说，扮演穆斯林角色会牺牲领土的稳定性以换取对个人特质和基因池的更好控制。当二者都能被妥善管理时，角色的领地通常会比大多数[[Christianity|基督教徒]]要强大。然而，事情也很容易转向另一个极端，让你的领地在一眨眼的功夫就土崩瓦解。

通常，在早期的[[开局时间]]伊斯兰教是一个很强大的宗教。和弱小破裂的基督教国家相比，伊斯兰教拥有数个大型王国和帝国，只有拜占庭帝国能够作为东正教的希望之光。在后期剧本，虽然随着时间推移基督教实力逐渐增长，而许多伊斯兰国家因家族分裂而走向破碎，但伊斯兰教不论在''《王国风云2》''游戏内外仍然十分强大。

==Denominations and common features==
There are three major denominations of Islam: Sunni, Shi'a, and Ibadi, which share a number of common features.
* '''Iqta [[government]]''' is a special variant of [[feudalism]] that allows [[nobles]] to hold [[temple]]s without penalty. (As such, there are no theocracies in Muslim realms.) Iqta also allows [[tyranny]]-free [[Title revocation|revocation]] of [[duchies]] and [[Diplomatic actions#Retract vassal|vassal retraction]]. Additionally, without {{icon|con}}[[Conclave]], law changes are unilateral by the liege and paid for with [[Piety]] rather than requiring vassals to vote their agreement.
**While vassal temple holders do provide Piety to their liege, the breakdown is not listed in the Religion tab like other religions.
**Modifiers which affect church opinion have no effect in Muslim realms. These include the modifiers from virtues and sins, the +20 from Theology focus, the -10 from joining the Hermetic Society, and the -10 from borrowing from Jews.
* Succession for Iqta and [[Tribal]] rulers is restricted to '''agnatic [[open]] (Turkish) succession''', giving all titles to the most powerful son (or paternal grandson). Titles rarely split or consolidate due to inheritance.
** The {{icon|con}}[[Conclave]] DLC adds laws that allow [[feudal elective]] and other gender preferences for Iqta realms.
* '''[[Polygamy]]''' allows Muslim men to take up to four wives.
* '''[[Decadence]]''' tends to weaken powerful dynasties in iqta and tribal realms, allowing lieges to revoke titles (using Fatwas) or even causing empires to collapse.
*'''Hostility among brothers and half-brothers''': full brothers have -20 to their opinion towards each other; half-brothers have -40.
* The {{iconify|Sayyid}} trait denotes direct male-line descent from Muhammad's relatives. The {{iconify|Mirza}} trait denotes a son of a Sayyid mother. Both traits improve Muslim opinion and make it easier to [[Religious head#Creating a caliphate|declare oneself Caliph]].
* A war with a Muslim of the same sect costs some [[Piety]] per month for the duration.
* Additional ''[[casus belli]]'':
** County Conquest: For 50 [[Piety]], a Muslim ruler may declare war for any [[province]] bordering their lands. Upon victory for a duke-rank or higher attacker, single-province counts are vassalized; otherwise the county is transferred to the victor.
** Invasion: For 1000 Piety, a Muslim ruler may attempt to conquer all territory in a [[de jure]] [[kingdom]] held by a ruler of a different religion bordering their lands. Upon victory, all vassals within the kingdom's de jure borders are transferred to the victor, while provinces held by rulers also owning land outside the kingdom are seized.
** Modified [[Casus_belli#Holy_War|Holy War]] CB:
*** Muslims may use the holy war CB against non-heretic Muslims of other denominations in addition to heretics of their own denomination and infidels.
*** Muslims may target, or be targeted by, realms up to two [[sea zone]]s distant before the era of [[great holy war]]s is unlocked.
*** Muslims vassalize rather than usurp titles gained in holy wars against non-Muslims
***Muslims lose decadence with holy war victories, but gain even more decadence should they lose.
* Unique [[decisions]]:
** [[Decisions#Go on Hajj to Mecca|Go on Hajj to Mecca]], an event chain similar to pilgrimages found in other religions. Unlike the pilgrimage decision, it is available at all times, whereas pilgrimages require the {{iconify|Theology focus}}.
**[[Decisions#Observe Ramadan|Observe Ramadan]], the holy month involving daily fasts by all healthy Muslims. This is a festival event chain that may be undertaken once every 5 years. It awards piety and reduces Decadence, and may add traits.
**[[Decisions#Sadaqah (Voluntary Charity)|Sadaqah (Voluntary Charity)]]: Charitable works that pay 25% of your yearly income for piety and improved opinion from your Caliph, if one exists (cannot be performed by the Caliph himself).

Most denominations and heresies feature a head of religion called a [[Religious head#Caliphates|caliph or sheikh]] who has far more secular power than Christian popes or patriarchs. The caliph or sheikh can use their own unique [[Casus Belli]], Caliphal Subjugation, to conquer [[kingdoms]] from rulers of the same religion. They can also call [[jihad]]s to conquer kingdoms from infidels. Unlike Christian, [[Jewish]], or [[Zoroastrian]] religious heads (but like the [[Pagans#Reformation|Reformed Germanic]] Fylkir in {{icon|tog}}''[[The Old Gods]]'' or {{icon|hf}} any head of a reformed pagan faith with the ''Temporal'' leadership type), Muslim religious head titles are playable.

All denominations save Yazidism share three holy sites in common (the remaining two varies):
* '''Mecca''': The birthplace of the Prophet Muhammad and the site where he received the first revelation of the Qur'an. All good Muslims who are physically and financially able are expected to undertake a formal pilgrimage, or ''hajj'', to Mecca once in their lives, a practice designated one of the Five Pillars of Islam.
* '''Medina:''' Historically the secular capital of Islam and the city to which Muhammad and his followers fled to avoid persecution.
* '''Jerusalem:''' The historic seat of the Abrahamic faiths, to which God took Muhammad in a night journey during the revelation of the Qur'an according to Islamic tradition.
**Mecca and Jerusalem are important {{icon|hl}}{{icon|jd}}[[Silk Road]] counties.
==={{iconify|Sunni}}逊尼派===
[[file:Hssunni.png|thumb|right|Map of Sunni holy sites.]]
Much like the Great Schism in Christianity, the Sunni-Shi'a split is a defining schismatic moment in Islam's history, though its roots are mainly political rather than theological: a disagreement over the succession of the caliphate immediately following the Prophet Muhammad's death in 632 A.D. This led to an extended period of civil war resulting in the violent deaths of three of the first four caliphs.

Sunni Islam, which won the initial sectarian conflict, holds that the Prophet Muhammad's rightful successor and therefore first Caliph of Islam was his father-in-law Abu Bakr. It has historically been the majority denomination. Sunnis' unique holy sites are '''Baghdad''' (shared with [[Christianity#Nestorian|Nestorian Christians]]) and '''Cordoba''' (shared with [[Aztecs]]). 
*Baghdad is an important {{icon|hl}}{{icon|jd}}[[Silk Road]] county.

With the {{icon|soa}}[[Sons of Abraham]] DLC, Sunnis can select between the {{iconify|Mutazilite}} and {{iconify|Ashari}} traits, representing belief in a particular flavor of Sunni Islam. Mutazilite adds +5 learning and provides [[technology]] boosts, while Ashari prevents personal decadence and provides piety boosts. Each trait has +15 same opinion and -25 opposite opinion.

Sunnis gain a [[holy order]], the {{w|Bektashi Order}}, if jihads are unlocked and either the year is 1228, or either Baghdad, Damascus, Cairo, Jerusalem or Mecca are not controlled by a Muslim character.

Notable Sunni realms in ''Crusader Kings II'''s timeframe include:
* The Umayyad Sultanate of Andalusia in {{icon|cm}}769, which usually expands to encompass all of the [[Empire]] of Hispania unless the player character intervenes. At the Stamford Bridge start, the empire has shattered into a dozen smaller realms, and Catholic Castille has taken most of Spain by the Rise of the Hansa start.
* The Abbasid Empire controls most of the Middle East from Egypt to Pakistan in 769. The empire still exists in {{icon|tog}}867, but is weakened.
* The Seljuk Sultanate is a significant powerbase in all bookmarks it is present in. 
* In the Hundred Years' War start, the Mongol Golden Horde is Sunni.

====Sunni heresies [[File:Sunni Heresy.png]]====

Sunni Islam has two playable [[heresy|heresies]], Yazidism and Zikrism.

[[file:Hsyazidi.png|thumb|right|Map of Yazidi holy sites.]]
;Yazidi
:{{w|Yazidis|Yazidism}} is a monotheistic faith native to what is now central Iraq, believing God to have placed the Earth in the care of seven angels. Historically the Yazidis were persecuted well into the 21st century AD as purported polytheists and/or devil worshippers, as the Peacock Angel Melek Taus is equated by some to Iblis. In ''Crusader Kings II'', the faith is implemented as a Sunni heresy with additional unique mechanics.

:Yazidism has its own unique set of holy sites, '''Nishapur, Dashtestan, Mosul, Mecca,''' and '''Jerusalem''' (the latter two shared with other Islamic denominations). No Yazidi rulers exist in the game by default, though the counties of Mosul and Kurdistan are majority Yazidi beginning in the Latin Empire bookmark.

:A Yazidi ruler who controls Mosul can declare themselves the Yazidi Sheikh, a caliph-equivalent religious head, by [[decision]] for 1000 [[Piety]]. In addition to the common powers of caliphs and sheikhs, the Yazidi Sheikh has the power to [[excommunicate]] characters. Being {{iconify|Sayyid}} or {{iconify|Mirza}} has no effect on the decision.

;Zikri:
:{{w|Zikri}}sm, also called Mahdavia, is a sect founded in India in the late 15th century (making its inclusion in ''Crusader Kings II'' ahistorical). It follows the teachings of Syed Muhammad Jaunpuri, who declared himself the messianic figure Imam Mahdi before the Kaaba in Mecca.

:Zikrism has no available religious head and thus cannot declare jihads. However, it is regarded as one of the better religions in ''Europa Universalis IV'', so it may be useful to a player who plans to [[Europa Universalis 4 Save Converter|export their save]] to the next game.

==={{iconify|Shia}}什叶派===
[[file:Hsshiite.png|thumb|right|Map of Shi'a holy sites.]]
Shi'ism, historically centered in Persia and later Iran, holds that Muhammad's rightful successor as caliph was his son-in-law Ali ibn Abi Talib (the 4th Caliph by the Sunni succession), rather than Abu Bakr. Shi'a's unique holy sites are '''Al Nadjaf''' and '''Damascus''' (Damascus is an important {{icon|hl}}{{icon|jd}}[[Silk Road]] county and shared with [[Judaism]]). If there is no Shi'a Caliph, a Sunni realm may experience a [[Casus Belli#Rise of the Shia Caliphate|Rise of the Shia Caliphate]] event rebellion.

Shi'a rulers and provinces exist at every start date, though they are more powerful as time goes on. The most powerful Shi'a realm in ''Crusader Kings II'' is the Ilkhanate in the Hundred Years War bookmark, a relatively large empire spread from the Caspian Sea to Pakistan. The Fatimid dynasty in the 1066 start holds Egypt and Jerusalem, as well as the Shi'a Caliphate, and is the strongest Shi'a realm in the standard bookmarks, though the Catholic Crusades targeting Jerusalem from the 1090s and onwards tend to severely reduce their strength.

Shi'a gains a holy order, the {{w|Assassins|Hashashin}}, if there are count+ Shi'a rulers in 1089 or later. Shi'ism also has a unique [[society]] in ''[[Monks and Mystics]]'', the Assassins (who historically were the same group as the Hashashin).

====Shi'a heresies [[File:Shia Heresy.png]]====
Shi'ism has two playable heresies, Druze and Hurufi.

;Druze
:The {{w|Druze}} are a unitarian sect from Western Asia (most common in the Levant in modern times) that syncretizes Islamic philosophies such as Ismailism with, among others, classical Greek philosophy, Gnosticism, and [[Hindu]]ism. They have frequently faced religious persecution and are not traditionally considered truly Muslim.

:Druze has no available religious head and thus cannot declare jihads.

;Hurufi
:{{w|Hurufism}} is a Sufi movement founded in the late 14th century by the Iranian mystic Fazlallah Astarabadi.

:A Hurufi Sheikh title may be created by decision under the same conditions as a normal caliphate.

==={{Iconify|Ibadi}}伊巴底派===
[[file:Hsibadi.png|thumb|right|Map of Ibadi holy sites.]]
Ibadism is a primarily South Arabian and North African denomination said to predate the Sunni and Shi'a denominations, much as Coptic Christianity predates Catholicism and Orthodoxy. Ibadi beliefs are a blend of the other two major denominations. E.g. Ibadis agree with Sunnis that Abu Bakr was the rightful first caliph, but agree with Shiites that God will not show Himself to Muslims on the Day of Judgement.

Ibadis' unique holy sites are the '''Atlas Mountains''' and '''Suhar'''. Ibadi and heretical Kharijite provinces are available in North Africa and southeastern Arabia (modern-day Oman) at all dates, but no Ibadi rulers exist after The Old Gods bookmark.

An Ibadi Caliphate can be established under the same rules as a Sunni or Shi'a Caliphate. Ibadis gain a holy order, the {{w|Haruriyyah}}, if jihads are unlocked and one of the following counties is not under Muslim control: Hajar, Damascus, Cairo, Jerusalem or Mecca.

===={{Iconify|Kharijite}}伊巴底派异端====
{{w|Khawarij|Kharijites}} are a sect related to the Ibadis and deemed heretical by much of mainstream Islam. They reject doctrines of caliphal infallibility (agreeing with Sunnis, disagreeing with Shi'ites) and the Umayyad Caliphate's assertion of divine right, as well as the notion that imams and caliphs must be of the Quraysh tribe (favoring instead the quasi-democratic belief that any pious Muslim nominated by other Muslims may be caliph), and believe that any Muslim has the duty to overthrow a sinful or heretical ruler. They arose during the First Fitna, the succession crisis between Ali (who would become the 4th Sunni and 1st Shi'a Caliph) and Governor Muawiyah of Syria to succeed Caliph Uthman. Disagreeing with Ali for agreeing to arbitration to settle the dispute following his near-victory at the Battle of Siffin in 657, they rebelled against Ali and assassinated him in 661.

A Kharijite Caliphate can be established for 1000 Piety by a ruler who controls either Mecca and Medina, or Jerusalem, Damascus, and Baghdad. The Sayyid and Mirza traits have no effect. Kharijites otherwise play identically to Ibadis.

== Caliphates and Sheikdoms ==
: {{main|Religious head#Caliphates}}

Muslim rulers do not have purely spiritual heads as Christians do. Instead, the religion is controlled by a secular Caliph or Sheikh who often controls significant amounts of land.

== Managing decadence ==
: {{main|Decadence}}

'''Decadence:''' ''"deterioration, esp of morality or culture; decay; degeneration"''

Represents how indulgent and opulent a lifestyle you and your dynasty members lead. Islam is traditionally a religion of modesty, and so should your decadence get out of hand, your vassals will not think highly of you. If your decadence remains at 100% for too long, you risk either: A) Assassination by the Hashashin, or B) an invasion of your realm by a randomly generated tribe from the desert. The invasion will come in the form of an army with very large troop numbers. Any level of Decadence above 25% is detrimental in general, whereas if below 25%, it offers bonuses. The higher the decadence, the lower your demesne income, and the lower the morale of your troops. (Neutral point is 25%.)

Muslim patricians do not have decadence. In return, they cannot hold mosques in their demesne without penalty.

Decadence can be increased or decreased through various methods. 

'''The following will increase decadence:'''

* Game events/decisions
* Males of your dynasty with the {{iconify|Decadent}} trait. The chance to get this is increased by having sinful traits and decreased by being landed and having virtuous traits.
*Losing holy wars

'''The following are ways to manage decadence:'''

* Game events/decisions
* "Straightening up" decadent members of your Dynasty via a special button in the Religion tab. They may or may not accept, resulting in more actions (being able to imprison him or persuading him further)
* Giving titles to members of your dynasty
* Going on Hajj
* Observing Ramadan (various events will give you the option to lower decadence. However, if your character has negative traits, events may occur which forces your decadence to go up instead.)
* Invasion by a desert tribe (when a tribe invades you for having too much decadence, you instantly lose 50% decadence)
* Winning sieges and battles decreases Decadence
* Winning holy wars and contributions during jihads.
* If all else fails, killing the decadent member will remove both them and their {{iconify|Decadent}} trait. Banishing them will stop their contribution to the dynasty's decadence score if your realm is the largest one controlled by your dynasty.

As can be seen above, the larger your dynasty, the more difficult it becomes to manage decadence. This game mechanic is a curse for the large caliphates but a blessing for the smaller ones, and since dynasties with lower decadence will have a combat bonus, this gives smaller independent Muslim states a fighting chance. Furthermore, as Muslim rulers have more wives, this produces larger dynasties which then makes decadence management more difficult. One strategy for managing decadence is to marry wives who are past child-bearing age, but still have one or two to bear the required heir(s).

The chances to gain the {{iconify|Decadent}} trait increase with sinful traits such as {{iconify|Craven}}, and {{iconify|Arbitrary}}. Landless characters are also more likely to become decadent.

== Polygamy ==
:{{main|Polygamy}}

===Iqta===
Polygamy is simultaneously a blessing and a curse. The advantages are that you will almost always have a capable male heir. And, with Turkish succession, you can give one of your many sons with good congenital traits land, and he will become your heir. You also have up to four wives to pick from for traits without requiring a divorce, instead of just one with other religions. Muslims also establish [[non-aggression pact]]s and [[alliance]]s through their secondary wives as well as the primary wife. The disadvantages are that, out of your FOUR maximum wives, only one can be your primary wife. This is a prestigious position, and secondary wives with good Intrigue will take desperate measures to ensure that she is the primary wife (like killing her). Wives will also kill the children of other wives, to ensure that their child is heir.

A good way to counter this is having good Intrigue yourself and a good Spymaster. By placing your Spymaster in your capital to Scheme, you can discover plots by your other wives against your primary wife or preferred heir. You can then ask them to stop or throw them in the dungeons and banish/execute them, depending on how tyrannical you feel.

Another possible solution is having your wife with the best Intrigue be your primary wife. Most rulers will pick the wife with the best traits overall anyway, but if you pick the wife with the best Intrigue and pick one of her children as your heir, then she will not plot against you or your children or sic drunken assassins at you. The problem with picking a child of your primary wife is that he may not necessarily be the best ruler, and there may be a better child sired by your secondary wives.

A good compromise is to have two young wives with good traits and two others who are 40 (the oldest age at which marriage can be arranged for rulers).

===Tribal===
Tribal Muslims use the concubinage system; note that tribal rulers ''cannot'' ask for concubines from iqta rulers. You'll have to invite women from iqta realms to your court before making them your concubines.

===Merchant republics===
Polygamy is a major advantage for Muslim patricians over non-Muslims, as they are exempt from decadence and the family's [[trade post]] limit is increased by unlanded adult male dynasts in the patrician's court. It is far easier for polygamous Muslims to sire many legitimate sons (up to the cap of ten living legitimate offspring at a time).

== Managing succession ==
:{{Main|Open}}
Your father has gone to ride the white camels and eat raisins in paradise.  You have the most or best titles or are otherwise heir.  Since your father likely had many wives, you likely have many rivals.  This is the best time to begin planning for future decadence.  Upon succession, the game models Ottoman Turkish succession (first son back to the capital kills his brothers and rules).  

Hopefully, your father planned for your succession by marrying 1 or 2 old women (45 and above; use the character finder as using the "rings" button sets the maximum age of the bride at 40) and educating your brothers for contentment and virtues.  That will almost offset the full/half brother relations penalty.

===''[[Conclave]]''===
:{{main|Feudal elective}}
With the ''Conclave'' DLC, Muslim realms can gain access to [[feudal elective]] succession. This requires passage of the [[council law]] "Full council authority".

== Other differences ==

=== Iqta vassal obligations ===
Feudal and clerical tax and levy laws are combined as iqta laws for Muslims. The default tax rate is higher than normal feudal taxes, so Muslim kings tend to be richer than Christian kings. The difference is more pronounced when compared to Catholic realms, due to the taxation issues surrounding Catholic bishops and the Pope.

=== Free revocation of duchies & retraction of vassals===
Unlike Tribal and Feudal governments, rulers of Iqta governments can revoke duchies freely and retract vassals without incurring tyranny. Needless to say, this is extremely useful if one of your vassals gets too powerful — and if they rebel, that just means you might get a chance to take their sheikdoms as well!

=== Avunculate marriage is prohibited ===
All Muslim types (except Yazidi) do not allow marriages between uncle-niece and aunt-nephew.

=== Law changes ===
Unlike Christian realms, Muslim realms do not vote for law changes. A Muslim ruler can change it at will. However, it costs a small amount of Piety depending on the type of law being changed. (50 for Demesne and 100 for Crown). However, with {{icon|con}}Conclave, after the council law "Empowered Council" is enacted, law changes will function the same way as under regular Feudal government.

===Restricted use of {{icon|wol}}[[Carousing]] focus===
Muslims cannot adopt this focus unless they are {{iconify|Decadent}}, {{iconify|Drunkard}} or {{iconify|Hedonist}}. Also, AI Muslim characters will ''never'' agree to join a party unless they have one of the above traits.
