The succession to [[Muhammad]] in 632 led the Muslims to be split into two camps: the [[Sunnis]], who believed that the [[caliphs]] of the [[Islamic community]] should be chosen by a council, as in [[Saqifa]]; and a second group, the [[Shia]], who believed that Muhammad had named his successor to be [[Ali ibn Abi Talib]], his cousin and son-in-law.<ref name=":1">{{cite news|url=https://www.bbc.com/news/world-middle-east-16047709|title=Sunnis and Shia: Islam's ancient schism|publisher=BBC News|date=4 January 2016|access-date=5 May 2019|archive-date=11 October 2023|archive-url=https://web.archive.org/web/20231011083116/https://www.bbc.com/news/world-middle-east-16047709|url-status=live}}</ref>

Today there are differences in religious practice and [[Fiqh|jurisprudence]], traditions, and customs between Shia and Sunni Muslims. Although all Muslim groups consider the [[Quran]] to be divine, Sunni and Shia have different opinions on interpretations ([[hadith]]) of the Quran. In recent years, the relations between the Shias and the Sunnis have been increasingly marked by conflict.<ref>{{Cite web|url=https://www.cfr.org/sunni-shia-divide/#!/|title=The Sunni-Shia Divide|website=cfr.org|access-date=15 March 2022|archive-date=8 July 2017|archive-url=https://web.archive.org/web/20170708192227/https://www.cfr.org/peace-conflict-and-human-rights/sunni-shia-divide/p33176#!/|url-status=live}}</ref> The aftermath of the 1979 [[Iranian revolution]], which reconfigured Iran into a theocratic Islamic republic governed by [[Ayatollah|high-ranking Shia clerics]], had far-reaching consequences across the Muslim world. The [[Iraq War]] of 2003–2011 further influenced regional power dynamics, solidifying Shias as the predominant force in Iraq. Iran's ascent as a [[regional power]] in the Middle East, along with shifts in politics and demographics in Lebanon favouring Shia, has heightened Sunni concerns about their Sunni–Arab hegemony.<ref>{{Citation|last1=Bengio|first1=Ofra|title=Introduction|date=2011|url=https://doi.org/10.1057/9781137495068_1|work=The Sunna and Shi'a in History: Division and Ecumenism in the Muslim Middle East|pages=1–16|editor-last=Bengio|editor-first=Ofra|access-date=2024-01-07|place=New York|publisher=Palgrave Macmillan US|language=en|doi=10.1057/9781137495068_1|isbn=978-1-137-49506-8|last2=Litvak|first2=Meir|editor2-last=Litvak|editor2-first=Meir|url-access=subscription}}</ref> Recent years have witnessed the [[Iran–Saudi Arabia proxy conflict]], as well as [[Sectarian violence among Muslims|sectarian violence]] from Pakistan to Yemen, which became a major element of friction throughout the Middle East and South Asia.<ref name="auto">{{cite web|url=http://www.sasnet.lu.se/ishtiaqtext.html|title=Ishtiaq Ahmed on Pakistan movement|work=lu.se|url-status=dead|archive-url=https://web.archive.org/web/20090318142147/http://www.sasnet.lu.se/ishtiaqtext.html|archive-date=18 March 2009}}</ref><ref name="scribd.com">{{cite web|url=https://www.scribd.com/doc/7250853/Sunnis-and-Shiites|title=Sunnis and Shiites|via=Scribd|access-date=11 September 2017|archive-date=7 March 2016|archive-url=https://web.archive.org/web/20160307031954/https://www.scribd.com/doc/7250853/Sunnis-and-Shiites|url-status=live}}</ref> Tensions between communities have intensified during power struggles, such as the Shia led [[Bahraini uprising (2011–present)|Bahraini uprising]], the [[Iraqi civil war (2006–2008)|Iraqi Civil War]], the [[War in Iraq (2013–2017)|2013–2017 War in Iraq against ISIS]], as well as the Sunni led [[Syrian Civil War]].<ref name="Nasr, Vali 2006, p.106" /><ref name="Civil War">{{cite web|url=https://www.motherjones.com/news/featurex/2007/03/civil_war.html|title=Iraq 101: Civil War|work=Mother Jones|access-date=9 July 2018|archive-date=6 December 2008|archive-url=https://web.archive.org/web/20081206111805/http://www.motherjones.com/news/featurex/2007/03/civil_war.html|url-status=live}}</ref><ref>{{cite news|last=Arango|first=Tim|title=As Syrians Fight, Sectarian Strife Infects Mideast|url=https://www.nytimes.com/2013/06/02/world/middleeast/sunni-shiite-violence-flares-in-mideast-in-wake-of-syria-war.html?ref=global-home&_r=0|access-date=2 June 2013|newspaper=The New York Times|date=1 June 2013|author2=Anne Barnard|author3=Duraid Adnan|archive-date=13 July 2023|archive-url=https://web.archive.org/web/20230713001221/https://www.nytimes.com/2013/06/02/world/middleeast/sunni-shiite-violence-flares-in-mideast-in-wake-of-syria-war.html?ref=global-home&_r=0|url-status=live}}</ref> The self-styled [[Islamic State of Iraq and Syria]] (ISIS) launched a [[Persecution of Shias by the Islamic State|persecution of Shias]].

==Differences in beliefs and practices == {{See also|Sufi-Salafi relations}} {{Islam and other religions |width=19.0em}}

===Successors of Muhammad=== {{further|Rafidah|Succession to Muhammad|Twelvers}}

===Mahdi===

The [[Mahdi]] is the prophesied redeemer of Islam. While Shia and Sunnis differ on the nature of the Mahdi, many members of both groups<ref>Glasse, Cyril, ''The New Encyclopedia of Islam'', Altamira Press, 2001, p. 280</ref> believe that the Mahdi will appear at the end of the world to bring about a perfect and just Islamic society.

In Shia Islam, "the Mahdi symbol has developed into a powerful and central religious idea."<ref name="Muslim World 2004 p.421">Martin, Richard C., ed. (2004), "Mahdi", Encyclopedia of Islam and the Muslim world, Thomson Gale, p. 421</ref> Twelvers believe the Mahdi will be [[Muhammad al-Mahdi]], [[The Twelve Imams|the twelfth Imam]] returned from [[Occultation (Islam)|the occultation]], where he has been hidden by Allah since 874. Mainstream Sunnis' beliefs are somewhat different: The Mahdi forms an important component of Sunni eschatology, his appearance being considered the last of the minor signs of the [[Last Judgment|Day of Judgment]] before its major signs. They believe the Mahdi will be a descendant of Muhammad named Muhammad and will revive the faithful.

===Hadith=== The Shia accept some of the same ''[[hadith]]s'' of Muhammad used by Sunnis as part of the ''[[sunnah]]'' and the basis of divine law and religious practice. In addition, they consider the sayings of [[Ahl al-Bayt]] that are not attributed directly to Muhammad as hadiths. Shia do not accept many Sunni hadiths unless they are also recorded in Shia sources or the methodology of how they were recorded can be proven.

Some Sunni-accepted hadiths—for example by Aisha or [[Abu Hurairah#Shi'a view|Abu Hurairah]]—are less favored by Shia (Aisha's opposed Ali and [[Abu Hurairah#Shi'a view|Abu Hurairah]] is considered an enemy of Ali and according to Shia, only a Muslim for four years of his life before Muhammad's death. Although he accompanied Muhammad for only four years, he managed to record ten times as many hadiths as Abu Bakr and [[Ali]] each).<ref>{{cite web|url=http://www.al-islam.org/articles/abu-hurayra-and-falsification-traditions-yasin-al-jibouri|title=Abu Hurayra and the Falsification of Traditions (Hadith)|access-date=18 May 2015|website=al-islam.org|publisher=Ahlul Bayt Digital Islamic Library Project|last=al-Jibouri|first=Yasin|date=19 February 2014|archive-date=21 May 2015|archive-url=https://web.archive.org/web/20150521152128/http://www.al-islam.org/articles/abu-hurayra-and-falsification-traditions-yasin-al-jibouri|url-status=live}}</ref>

===Sufism=== Shiism and [[Sufism]] are said to share a number of hallmarks: Belief in an inner meaning to the Quran, special status for some mortals (saints for Sufi, Imams for Shia), as well as veneration of Ali and Muhammad's family.<ref>Nasr, Vali, ''The Shia Revival'', Norton, 2006, pp. 59–60</ref>

===Pillars of faith=== The [[Five Pillars of Islam]] ([[Arabic]]: أركان الإسلام) is the term given to the five duties incumbent on every Muslim and are held by both Sunni and Shia. These duties are ''[[Shahada]]'' (profession of faith), ''[[Salat]]'' (prayers), ''[[Zakāt]]'' (giving of alms), ''[[Sawm]]'' (fasting, specifically during [[Ramadan (calendar month)|Ramadan]]) and ''[[Hajj]]'' (pilgrimage to [[Mecca]]). In addition, [[Theology of Twelvers|Shia theology]] has two concepts that define religion as a whole. These are Roots of Religion (''Usūl al-Dīn'') and Branches of Religion (''[[Ancillaries of the Faith|Furu al Din]]'').

===Practices=== Many distinctions can be made between Sunnis and Shiaīs through observation alone:

====Salat==== [[File:Tehran Friday prayer - 16 March 2018 (13961225000386636568071894544919 84859).jpg|thumb|A Sunni Muslim (left) beside a Shia Muslim (right) showing different ways of holding arms during 16 March 2018 Tehran Friday prayer, [[Iran]].]] When prostrating during ''Salah,'' Shia place their forehead onto a piece of naturally occurring material—most often a clay tablet (''mohr'') or soil (''[[turbah]]'')—instead of directly onto a prayer rug.

There are five salat prayers at different times of the day, but unlike Sunni, some Shia combine two sets of the prayers, (1+2+2, i.e. ''[[fajr]]'' on its own, ''[[Dhuhr]]'' with ''[[Asr]]'' and ''[[Maghrib (prayer)|Maghrib]]'' with ''[[Isha']]'') praying five times per day but with a very small break in between the prayer, instead of five prayers with some gap between them as required by Sunni [[Madh'hab|schools of law]].<ref name="islamfortoday2007"/>

Shia and the followers of the Sunni Maliki school hold their hands at their sides during prayer while Sunnis of other schools cross their arms (right over left) and clasp their hands;<ref name="Nasr, Vali 2006, p.43">Nasr, Vali, ''The Shia Revival'', Norton, 2006, p. 43</ref> it is commonly held by Sunni scholars (especially of the Maliki school) that either is acceptable.<ref>{{cite book|title=Sharh-e-Muslim|page=28|author1=Nawawi|author2=translated by Maulana Waheed-uz-Zaman Knan|chapter=Volume 2|quote=Imam Ahmed Auzai and Ibn-e-Manzar have said that it is up to the worshipper to perform the prayer in the way he wants.

====Mut'ah and Misyar==== {{See also|Islamic marital practices}} The Twelver branch of Shia Islam<ref>{{cite web|url=http://www.worldatlas.com/articles/shia-islam-s-holiest-sites.html|title=Shia Islam's Holiest Sites|date=25 April 2017|access-date=10 December 2017|archive-date=23 April 2019|archive-url=https://web.archive.org/web/20190423193634/https://www.worldatlas.com/articles/shia-islam-s-holiest-sites.html|url-status=live}}</ref><ref>{{cite book|date=2008|title=Atlas of the Middle East|edition=Second|location=Washington, DC|publisher=[[National Geographic Society|National Geographic]]|pages=80–81|isbn=978-1-4262-0221-6}}</ref> permits ''[[Nikah mut'ah]]''<ref>[https://www.al-islam.org/nikah-al-mutah-zina-or-sunnah-toyib-olawuyi/3-allah-calls-mutah-good-thing Allah Calls Mut'ah "A Good Thing"] {{Webarchive|url=https://web.archive.org/web/20171210180115/https://www.al-islam.org/nikah-al-mutah-zina-or-sunnah-toyib-olawuyi/3-allah-calls-mutah-good-thing |date=10 December 2017 }} Retrieved 10 December 2017</ref><ref>[https://www.al-islam.org/completion-argument-maulana-sayyid-saeed-akhtar-rizvi/mutah-temporary-marriage#fref_e0fe9956_1 Mutah (Temporary Marriage)] {{Webarchive|url=https://web.archive.org/web/20171210180039/https://www.al-islam.org/completion-argument-maulana-sayyid-saeed-akhtar-rizvi/mutah-temporary-marriage#fref_e0fe9956_1 |date=10 December 2017 }} Retrieved 10 December 2017</ref>—fixed-term temporary marriage. The practice is not allowed within the Sunni community, nor within the Ismaili Shia or the Zaidi Shia, who consider it planned and agreed fornication rather than marriage. These schools believe that mutah was permitted until Umar forbade it during his rule. (Mutah is not the same as ''[[Nikah Misyar|misyar]]'' marriage or '' 'arfi'' marriage, which has no date of expiration and is permitted by some Sunnis. A misyar marriage differs from a conventional [[Marriage in Islam|Islamic marriage]] in that the man does not have financial responsibility of the woman by her own free will. The man can divorce the woman whenever he wants to in a misyar marriage.)<ref>{{cite web|url=http://lexicorient.com/e.o/misyar.htm|title=Misyar marriage|access-date=25 August 2009|publisher=lexicorient.com|archive-date=28 February 2021|archive-url=https://web.archive.org/web/20210228050620/http://lexicorient.com/e.o/misyar.htm|url-status=dead}}</ref>

====Hijab and dress==== {{See also|Islam and clothing}} Both Sunni and Shia women wear the ''[[hijab]]''. Devout women of the Shia traditionally wear black as do some Sunni women in the [[Persian Gulf]]. Some Shia religious leaders also wear a black robe. Mainstream Shia and Sunni women wear the ''hijab'' differently. Some Sunni scholars emphasize covering of all body including the face in public whereas some scholars exclude the face from hijab. Shia believe that the hijab must cover around the perimeter of the face and up to the chin.<ref name=Hijab>{{cite web|last1=Rizvi|first1=Sayyid Muhammad|title=Hijab, The Muslim Womens Dress, Islamic or Cultural?|url=http://www.al-islam.org/hijab-muslim-womens-dress-islamic-or-cultural-sayyid-muhammad-rizvi/sunna-and-hijab|website=Al-Islam|date=29 December 2012|publisher=Ja'fari Islamic Centre (Tabligh Committee) Canada|access-date=3 March 2015|archive-date=15 May 2021|archive-url=https://web.archive.org/web/20210515195928/https://www.al-islam.org/hijab-muslim-womens-dress-islamic-or-cultural-sayyid-muhammad-rizvi/sunna-and-hijab|url-status=live}}</ref> Like Sunnis, some Shia women, such as those in Iran and Iraq, use their hand to hold the black ''[[chador]]'' to cover their faces when in public.

====Given names==== Muslims are often named after famous early Muslims, so that given names of Shia are often derived from the names of [[Ahl al-Bayt]].

==History==

===Early and pre-modern history=== {{further|History of Islam}} The [[origin of Shia Islam]] arose in response to the [[succession to Muhammad]] and whether [[Ali ibn Abi Talib]] or a more experienced member of the [[Quraysh tribe]] should succeed. The concept of Shi'ism further crystallized around events at the [[Battle of Karbala]] (680 CE) where [[Husayn ibn Ali]], the son of Ali and grandson of Muhammad, was killed alongside many of his supporters. Thus a political split became a far more personal one, marked by [[blood feud]], and a cause for further divergence.

Even so, by the 13th to 14th century, Sunni and Shia practices remained highly intertwined, and figures today commonly associated with Shia Islam, such as Ali and [[Jafar al-Sadiq]], played an influential role for all Muslims.<ref name=Peacock>{{Cite book|first1=A.C.S.|last1=Peacock|title=Islam, Literature and Society in Mongol Anatolia|publisher=Cambridge University Press|date=2019|page=24|doi=10.1017/9781108582124|isbn=9781108582124|s2cid=211657444}}</ref>

====Abbasid era==== [[File:Destruction of the Tomb of Husain at Kerbela.jpg|thumb|Destruction of the Tomb of [[Husayn ibn Ali]] at [[Karbala]], condemned in a [[Mughal Empire|Mughal]] era manuscript.]]

The [[Umayyad Caliphate|Umayyads]] were overthrown in 750 by a new dynasty, the [[Abbasid Caliphate|Abbasids]]. The first Abbasid caliph, [[As-Saffah]], recruited Shia support in his campaign against the Umayyads by emphasising his blood relationship to Muhammad's household through descent from his uncle, [['Abbas ibn 'Abd al-Muttalib]].<ref>''The March of Islam: Time Frame, AD 600–800'', p. 48. Pub. Robert H. Smith. [[Alexandria, Virginia|Alexandria]]: [[Time Life]], 1988. {{ISBN|0809464217}}</ref> The Shia also believe that he promised them that the caliphate, or at least religious authority, would be vested in the Shia imam. As-Saffah assumed both the temporal and religious mantle of caliph. He continued the Umayyad dynastic practice of succession, and his brother [[al-Mansur]] succeeded him in 754. [[Ja'far al-Sadiq]], the sixth Shia imam, died during al-Mansur's reign, and there were claims that he was murdered on the orders of the caliph.<ref>''[[Ya'qubi]]; vol. III'', pp. 91–96, and ''[[Concise History of Humanity (book)|Tarikh Abul Fida]]'', vol. I, p. 212.</ref> (However, Abbasid persecution of Islamic scholars was not restricted to the Shia. [[Abū Ḥanīfa]], for example, was imprisoned by al-Mansur and tortured.)

Shia sources further claim that by the orders of the tenth Abbasid caliph, [[al-Mutawakkil]], the tomb of the third imam, Hussein ibn Ali in Karbala, was completely demolished,<ref>''[[Bihar al-Anwar]]'', vol. XII, on the life of Imam Ja'far al-Sadiq</ref> and Shia were sometimes beheaded in groups, buried alive, or even placed alive within the walls of government buildings still under construction.<ref>''[[Shi'a Islam (book)|Shi'a Islam]]'', p. 62</ref> The Shia believe that their community continued to live for the most part in hiding and followed their religious life secretly without external manifestations.<ref>[[Ya'qubi]]. vol.

====Iraq==== {{Main|Shia Islam in Iraq}} Iraq holds a unique and foundational position in the history of Shia Islam. The roots of the Iraqi Shia community are deep, dating back to the seventh century. Ali ibn Abi Talib, moved the capital of the Rashidun Caliphate from Medina to [[Kufa]] in Iraq.<ref>The New Encyclopædia Britannica, Jacob E.

Six of the Twelve Imams have their tombs located in Iraq.

In the early Islamic period, Iraq served as a primary hub for Shia scholarship and political activity. It was home to many renowned disciples of the Shia Imams and witnessed several uprisings against Umayyad rule, including those led by [[Sulayman ibn Surad]] and [[Mukhtar al-Thaqafi]].<ref>{{cite book|last=Al-Abdul Jader|first=Adel S.|editor-last=Suleiman|editor-first= Yasir|editor-link=Yasir Suleiman|year=2010|title=Living Islamic History: Studies in Honour of Professor Carole Hillenbrand|chapter=The Origin of Key Shi'ite Thought Patterns in Islamic History|chapter-url=https://books.google.com/books?id=QRirBgAAQBAJ|publisher=[[Edinburgh University Press]]|location=Edinburgh|isbn=978-0-7486-4219-9}}</ref><ref>{{EI3|last=Haider|first=Najam|title=al-Mukhtār b.

Medieval Iraq saw the rise of several native Shia dynasties that ruled parts of Iraq. In the 10th and 11th centuries, [[Hamdanid dynasty]] established an emirate in northern Iraq from their base in [[Mosul]].<ref>{{cite book |last=Bosworth |first=C.E. |title=The New Islamic Dynasties |publisher=Columbia University Press |year=1996 |quote=The Hamdanids came from the Arab tribe of Taghlib..[..]...the Hamdanids tended to follow the Shī'ī inclinations... }}</ref><ref>{{EI2 | volume=3 | title=Ḥamdānids | first = Marius | last = Canard | authorlink = Marius Canard | pages = 126–131 | url = http://referenceworks.brillonline.com/entries/encyclopaedia-of-islam-2/hamdanids-COM_0259}}</ref> They were succeeded by other Shia dynasties like the [[Uqaylid dynasty|Uqaylids]]. In central Iraq, the [[Banu Mazyad|Mazyadids]], ruled an autonomous emirate from their capital, [[Hillah]], from 961 to 1160, making it a major center for Shia scholarship.<ref>{{EI2|first=C.

[[Ottoman Iraq|Early-modern Iraq]] became a religious battleground between the neighboring [[Ottoman Empire|Ottoman]] and [[Safavid Iran|Safavid]] Empires. For the Sunni Ottomans, who subscribed to the [[Hanafi school|Hanafi school of thought]], control over Iraq, and particularly Baghdad, the site of [[Abu Hanifa Mosque|Abu Hanifa's shrine]], was a major source of religious legitimacy.<ref>{{cite book |last=Burak |first=Guy |title=The Second Formation of Islamic Law: The Ḥanafī School in the Early Modern Ottoman Empire |place=Cambridge |publisher=Cambridge University Press |year=2015 |isbn=978-1-107-09027-9 |page=1}}</ref> Conversely, for the Twelver Shia Safavids, sovereignty was fought for primarily due to the presence of the [[Al-Atabat Al-Aliyat]], that is, the holy shrine cities of [[Najaf]], [[Karbala]], [[Kadhimiya]], and [[Samarra]].<ref>{{Cite book |last=Nakash |first=Yitzhak |url=https://www.jstor.org/stable/j.ctv36zqt4.8 |title=The Shi'is of Iraq |publisher=Princeton University Press |year=1994 |page=14}}</ref> This rivalry resulted in centuries of conflict, plunging Iraq into a prolonged period of warfare in a religious struggle between the two major Islamic powers.

The Shia majority in Iraq was formed primarily through the mass conversion of Sunni Arab tribes in the 18th and 19th centuries. This process began after the collapse of the Safavid Iran in 1722 which recentered Shia learning back to Iraq, in Najaf and Karbala. The [[Wahhabi sack of Karbala]] in 1801 motivated the Shia scholars to convert tribes to secure their cities. A key trigger was the Ottoman policy of tribal settlement after 1831, which forced nomads into agriculture, disrupted their society, and created an identity crisis that made them receptive to conversion. This was aided by the construction of the Hindiyya canal, which drew tribes to settle in the fertile lands around the Shia holy cities, bringing them under the direct influence of Shia scholars.<ref>{{Cite journal |last=Nakash |first=Yitzhak |date= |year=1994 |title=The Conversion of Iraq's Tribes to Shiism |journal=International Journal of Middle East Studies |volume=26 |issue=3 |pages=443–463 |jstor=163698}}</ref>

The [[Ottoman–Persian Wars|Ottoman-Persian rivalry]] split Iraq's society, as the state legally treated its Shia citizens as potential Persian subjects. Native Iraqi Arab and Kurdish Shias were often categorized as Persian subjects (taba'iyya iraniyya), a classification the Ottoman state used to justify discriminatory policies. These included religious fatwas condemning Shia as heretics and laws, such as those in 1822 and 1874, that prohibited marriage between Ottoman women and Shia men. This framework of viewing the Shia population through a lens of imperial security and sectarian difference continued to influence policies in the modern Iraqi state.<ref>{{Cite journal |last=Saleh |first=Zainab |date=Spring 2013 |title=ON IRAQI NATIONALITY: LAW, CITIZENSHIP, AND EXCLUSION |journal=The Arab Studies Journal |volume=21 |issue=1 |pages=48–78 |jstor=41968268}}</ref>

====Persia==== {{Main|Islam in Iran}}

[[Shafi'i school|Shafi'i]] Sunnism was the dominant form of Islam in most of Iran until rise of the [[Safavid dynasty|Safavid Empire]] although a significant undercurrent of [[Isma'ilism|Ismailism]] and a large minority of Twelvers were present all over Persia. The Sunni hegemony did not undercut the Shia presence in Iran. The writers of [[The Four Books|the Shia Four Books]] were Iranian, as were many other scholars. According to [[Morteza Motahhari]]:<ref name="Motahhari">{{cite web|url=http://www.al-islam.org/al-tawhid/vol6-n2-1989/islam-and-iran-historical-study-mutual-services-ayatullah-murtadha-mutahhar-0|title=Islam and Iran: A Historical Study of Mutual Services Part 2|work=Al-Islam.org|date=13 March 2013|access-date=2 January 2014|archive-date=26 October 2014|archive-url=https://web.archive.org/web/20141026164048/http://www.al-islam.org/al-tawhid/vol6-n2-1989/islam-and-iran-historical-study-mutual-services-ayatullah-murtadha-mutahhar-0|url-status=live}}</ref>

{{blockquote|The majority of Iranians turned to Shi'ism from the Safawid period onwards. Of course, it cannot be denied that Iran's environment was more favourable to the flourishing of the Shi'ism as compared to all other parts of the Muslim world. Shi'ism did not penetrate any land to the extent that it gradually could in Iran. With the passage of time, Iranians' readiness to practise Shi'ism grew day by day. Had Shi`ism not been deeply rooted in the Iranian spirit, the Safawids (907–1145/1501–1732) would not have succeeded in converting Iranians to the Shi'i creed [[Ahl al-Bayt]] sheerly by capturing political power.}}

=====Pre-Safavid===== [[File:Nakkaş Selim.jpg|thumb|[[Selim I|Yavuz Sultan Selim]] who delivered a devastating blow to the Shia Safavids and [[Ismail I]] in the [[Battle of Chaldiran]], a battle of historical significance.]] The domination of the Sunni creed during the first nine Islamic centuries characterizes the religious history of Iran during this period. There were some exceptions to this general domination which emerged in the form of the Zaidis of [[Tabaristan]], the [[Buyid dynasty|Buwayhid]], the rule of the [[Sultan]] [[Öljaitü|Muhammad Khudabandah]] (r. 1304–1316) and the [[Sarbadars|Sarbedaran]]. Nevertheless, apart from this domination there existed, firstly, throughout these nine centuries, Shia inclinations among many Sunnis of this land and, secondly, Twelver and Zaidi Shiism had prevalence in some parts of Iran. During this period, the Shia in Iran were nourished from [[Kufa]], [[Baghdad]] and later from [[Najaf]] and [[Al Hillah]].<ref>{{cite web|url=http://www.al-islam.org/mot/iraqishiism/|title=Four Centuries of Influence of Iraqi Shiism on Pre-Safavid Iran|work=Al-Islam.org|date=27 February 2013|access-date=12 October 2013|archive-date=4 September 2013|archive-url=https://web.archive.org/web/20130904232915/http://www.al-islam.org/mot/iraqishiism/|url-status=live}}</ref> Shia were dominant in Tabaristan, [[Qom]], [[Kashan]], [[Avaj]] and [[Sabzevar]]. In many other areas the population of Shia and Sunni was mixed.

The first Zaidi state was established in [[Dailamites|Daylaman]] and Tabaristan (northern Iran) in 864 by the [[Alavids]];<ref>Article by Sayyid 'Ali ibn 'Ali al-Zaidi, ''At-tarikh as-saghir 'an ash-shia al-yamaniyeen'' (Arabic: التاريخ الصغير عن الشيعة اليمنيين, A short History of the Yemenite Shi'ites), 2005 Referencing: Iranian Influence on Moslem Literature</ref> it lasted until the death of its leader at the hand of the [[Samanids]] in 928. Roughly forty years later the state was revived in [[Gilan province|Gilan]] (north-western Iran) and survived under Hasanid leaders until 1126. After which from the 12th–13th centuries, the Zaidis of Daylaman, Gilan and Tabaristan then acknowledged the Zaidi [[Imam]]s of Yemen or rival Zaidi Imams within Iran.<ref>Article by Sayyid 'Ali ibn 'Ali Al-Zaidi, ''At-tarikh as-saghir 'an ash-shia al-yamaniyeen'' (Arabic: التاريخ الصغير عن الشيعة اليمنيين, A short History of the Yemenite Shi'ites), 2005 Referencing: Encyclopedia Iranica</ref>

The Buyids, who were Zaidi and had a significant influence not only in the provinces of Persia but also in the capital of the caliphate in Baghdad, and even upon the caliph himself, provided a unique opportunity for the spread and diffusion of Shia thought. This spread of Shiism to the inner circles of the government enabled the Shia to withstand those who opposed them by relying upon the power of the caliphate.

Twelvers came to Iran from Arab regions in the course of four stages. First, through the Asharis{{Clarify|date=August 2013}} at the end of the 7th and during the 8th century. Second through the pupils of Sabzevar, and especially those of [[Al-Shaykh Al-Mufid]], who were from [[Rey, Iran|Rey]] and [[Sabzawar]] and resided in those cities. Third, through the school of Hillah under the leadership of [[Allamah Al-Hilli|Al-Hilli]] and his son Fakhr al-Muhaqqiqin. Fourth, through the scholars of [[Jabal Amel]] residing in that region, or in Iraq, during the 16th and 17th centuries who later migrated to Iran.<ref name="Jafarian2">{{cite web|url=http://www.imamreza.net/eng/imamreza.php?print=589|title=A Study of the Migration of Shi'i Works from Arab Regions to Iran at the Early Safavid Era. – Imam Reza (A.S.)

On the other hand, the Ismaili [[Dawah|da'wah]] ("missionary institution") sent missionaries (''du'āt'', sg. ''dā'ī'') during the [[Fatimid Caliphate]] to Persia. When the Ismailis divided into two sects, [[Nizari]]s established their base in northern Persia. [[Hassan-i Sabbah]] conquered fortresses and captured [[Alamut]] in 1090. Nizaris used this fortress until the [[Mongols]] finally seized and destroyed it in 1256.

After the Mongols and the fall of the Abbasids, the Sunni [[Ulama]] suffered greatly. In addition to the destruction of the caliphate there was no official Sunni school of law. Many libraries and madrasahs were destroyed and Sunni scholars migrated to other Islamic areas such as [[Anatolia]] and Egypt. In contrast, most Shia were largely unaffected as their center was not in Iran at this time. For the first time, the Shia could openly convert other Muslims to their movement.

Several local Shia dynasties like the [[Marashi]] and Sarbadars were established during this time. The kings of the [[Kara Koyunlu]] dynasty ruled in [[Tabriz]] with a domain extending to [[Fars province|Fars]] and [[Kerman]]. In Egypt the Fatimid government ruled.<ref name="athir">''al-Ka-mil'' of [[Ibn Athir]], Cairo, 1348; ''Raudat al-safa' ''; and ''Habib as-Siyar'' of Khwand Mir</ref>

Muhammad Khudabandah, the famous builder of [[Soltaniyeh]], was among the first of the Mongols to convert to Shi'ism, and his descendants ruled for many years in Persia and were instrumental in spreading Shī'ī thought.<ref>''Abu'l-Fida' '', vol. II, p. 63 and vol. III, p. 50</ref> Sufism played a major role in spread of Shiism in this time. {{blockquote|After the Mongol invasion Shiims and Sufism once again formed a close association in many ways. Some of the Ismailis whose power had been broken by the Mongols, went underground and appeared later within Sufi orders or as new branches of already existing orders. In Twelve-Imam Shiism, from the 13th to the 16th century, Sufism began to grow within official Shiite circles.<ref>Hossein Nasr (1972) p. 115</ref>

The [[Ghulat|extremist sects]] of the [[Hurufism|Hurufis]] and [[Shasha'a]] grew directly out of a background that is both [[Shia Islam|Shiite]] and Sufi. More important in the long run than these sects were the Sufi orders which spread in Persia at this time and aided in the preparing the ground for the Shiite movement of Safavids.

=====Post-Safavid===== [[Ismail I]] initiated a religious policy to recognize Shiism as the official religion of the Safavid Empire, and the fact that modern Iran and Azerbaijan remain majority-Shia states is a direct result of Ismail's actions.

However, most of Ismail's subjects were Sunni. As a result, he [[Safavid conversion of Iran from Sunnism to Shiism|enforced official Shiism]] violently, putting to death those who opposed him. Under this pressure, Safavid subjects either converted or pretended to convert.

This gap continued until the 20th century.

The Safavid dynasty of [[Iran|Persia]] was then deposed by the eastern Iranian [[Hotak dynasty|Hotak]] Sunni Muslims in the 18th century. [[Afghanistan]] today is a mostly Sunni country while Iran, a Shia majority.

====Hejaz==== In the holy cities of [[Mecca]] and [[Medina]], where Muslims, including Shia, perform [[Hajj]] (one of the pillars of Islam), tensions between Shia and Sunni have waxed and waned.

====Levant==== [[File:Masyaf6.jpg|thumb|left|200px|[[Rashid ad-Din Sinan]] the Grand Master of the Ismaili Shia at [[Masyaf]] successfully deterred [[Saladin]], not to assault the minor territories under the control of their sect.]]

The Shia faith in the Levant started spreading during the [[Hamdanid dynasty|Hamdanid]] rule, which commenced in the start of the 10th century. It was followed by the [[Mirdasid dynasty|Mirdasid Shi'ite emirate]] in the 11th century, with both the emirates centered at [[Aleppo]].

The general observations recorded by Muslim travellers passing through the Levant during the tenth and eleventh centuries, notably al-Maqdisi in his geographical works, "The best divisions in the knowledge of the regions", as well as [[Ibn Jubayr]], indicate that Shia Muslims made up the majority of the populations of the regions of the Levant during this era, notably in the cities of Damascus, Tiberias, Nablus, Tyre, Homs and Jabal Amel. In addition to the account of [[Nasir Khusraw]] who visited [[Jerusalem]] in the year 1045 AD and reported: "The population of Jerusalem is about 20,000, the populace being mostly Shi'a Muslims". However, with the advent of the [[Zengids]] and [[Ayyubids]], the population of Shia dwindled greatly due to conversion and migrations.

On 21 April 1802, about 12,000 Wahhabi Sunnis under the command of [[Abdul-Aziz bin Muhammad]], the second ruler of the First Saudi State attacked and [[Wahhabi sack of Karbala|sacked Karbala]], killed between 2,000 and 5,000 inhabitants and plundered the tomb of [[Husayn ibn Ali]], grandson of Muhammad and son of [[Ali ibn Abi Talib]],<ref name="Seyyed">{{cite book|last1=Khatab|first1=Sayed|title=Understanding Islamic Fundamentalism: The Theological and Ideological Basis of Al-Qa'ida's Political Tactics|year=2011|publisher=Oxford University Press|isbn=9789774164996|url=https://books.google.com/books?id=KBYnDAAAQBAJ&pg=PA74|access-date=11 August 2016}}</ref>{{rp|74}} and destroyed its dome, seizing a large quantity of spoils, including gold, Persian carpets, money, pearls, and guns that had accumulated in the tomb, most of them donations.

=====20th century===== Sunni–Shia clashes also occurred occasionally in the 20th century in India, particularly between 1904 and 1908. These clashes revolved around the public cursing of the first three caliphs by Shia and the praising of them by Sunnis. To put a stop to the violence, public demonstrations were banned in 1909 on the three most sensitive days: [[Day of Ashura|Ashura]], [[Arba'een|Chehlum]] and Ali's death on 21 Ramadan. Intercommunal violence resurfaced in 1935–36 and again in 1939 when many thousands of Sunni and Shia defied the ban on public demonstrations and took to the streets.<ref>Momen, Moojan, ''An Introduction to Shi'i Islam'', Yale University Press, 1985, p. 276</ref> Shia are estimated to be 10–15% of the Muslim population in [[Islam in India|India]] and [[Islam in Pakistan|Pakistan]] and less than 1% of Muslim population in [[Islam in Bangladesh|Bangladesh]], although the total number is difficult to estimate due to the intermingling between the two groups and practice of ''[[taqiyya]]'' by Shia.<ref>Momen, Moojan, ''An Introduction to Shi'i Islam'', Yale University Press, 1985, p. 277</ref>

===Modern history=== {{see also|Iran–Saudi Arabia proxy conflict}}

====1919–1979==== At least one scholar sees the period from the collapse of the Ottoman Empire through the decline of [[Arab nationalism]] as a time of relative unity and harmony between traditionalist Sunni and Shia Muslims. A unity brought on by a feeling of being under siege from a common threat, i.e. [[secularism]]—first of the European colonial variety and the Arab nationalist.<ref name="Nasr, Vali 2006, p.106">Nasr, Vali, ''The Shia Revival'', Norton, 2006, p. 106</ref>

An example of Sunni–Shia cooperation was the [[Khilafat Movement]] which swept South Asia following the defeat of the Ottoman Empire, the seat of the caliphate, in [[World War I]]. Shia scholars "came to the caliphate's defence" by attending the 1931 Caliphate Conference in [[Jerusalem]]. This was despite the fact that theologically Shia held that imams, not caliphs, were the successors to Muhammad, and that the caliphate was "the flagship institution" of Sunni, not Shia, authority. This has been described as unity of traditionalists in the face of the twin threats of "secularism and colonialism."<ref name="Nasr, Vali 2006, p.106"/>

That does not mean, however, that there was no friction at all. The Ottoman Empire had projected itself as a guardian of Sunni Islam. This had started, in part, during the sixteenth century in conflict with the Safavid Empire, which had shaped itself around its Shi'i identity. After the fall of the Safavids, this self-identification of the Ottoman Empire had faltered a little since there was no immediate Shi'i 'threat'. The later nineteenth century, under the reign of [[Sultan Abdul Hamid II]], the Sunni Islamic character of the Empire was again mobilized as a nationalist identity.<ref>{{cite book |last1=Deringil |first1=Selim |title=The Well-Protected Domains: Ideology and the Legitimation of Power in the Ottoman Empire 1876–1909 |date=1999 |publisher=I.B. Tauris |isbn=9781848857865 |url=https://archive.org/details/TheWellProtectedDomainsOttomanEmpire |ref=Deringil, The Well-Protected Domains}}</ref> In this context, conversations and polemical debates between Shi'i and Sunni thinkers on the topic of [[taqrib]], sometimes called Islamic [[ecumenism]], took place.<ref>{{cite book |last1=Brunner |first1=Rainer |title=Islamic Ecumenism in the 20th Century: The Azhar and Shiism between Rapprochement and Restraint |date=2004 |publisher=Brill |location=Leiden |isbn=978-90-47-40427-9 |url=https://brill.com/display/title/7771?language=en |ref=Brunner, Islamic Ecumenism}}</ref> These discussions centred around the topic of each other's legitimacy and saw the participation of many in the Islamic intellectual and political sphere. These discussion included contributions of the [[Azhari]] shaykh [[Mustafa al-Maraghi]], [[Rashid Rida]], and [[Abd al-Husayn Sharaf al-Din al-Musawi]],<ref>{{cite book |last1=Brunner |first1=Rainer |title=Islamic Ecumenism in the 20th Century: The Azhar and Shiism between Rapprochement and Restraint |date=2004 |publisher=Brill |location=Leiden |isbn=978-90-47-40427-9 |pages=51-120 |url=https://brill.com/display/title/7771?language=en}}</ref> and reached its peak with Mahmud Shaltut's fatwa later in the twentieth century.

The early twentieth century also saw the partition of the former Ottoman regions into new colonial [[protectorates]], or (semi-)independent nation-states. This meant that sects, [[madhhabs]], and denominations were administered differently in regions that had previously been under a more unified system. In some regions, like Lebanon for example, [[sectarian]] came to play an important role in state formation. This meant that on an administrative level, there was official recognition of the Shi'is in the establishment of a [[Ja'fari]] court in which Shi'is of the region could follow their own legal traditions, whereas in the Ottoman period, they had to follow, at least in name, the [[Hanafi]] school.<ref>{{cite book |last1=Deeb |first1=Lara |last2=Nalbaltian |first2=Tsolin |last3=Sbait |first3=Nadya |title=Practicing Sectarianism: Archival and Ethnographic Interventions on Lebanon |date=2023 |publisher=Stanford University Press |location=Stanford |isbn=1-5036-3387-X |pages=33-37 |url=https://www.sup.org/books/middle-east-studies/practicing-sectarianism |ref=Deeb et al., Practicing Sectarianism}}</ref>

Although Sunni and Shi'i sectarian identities on a religious and administrative level seemed to diverge during the period after the [[fall of the Ottoman Empire]], personal identification with either creed played a more ambiguous role. The recognition of a Ja'fari legal court (Shi'a) in Lebanon led Shi'is in other parts of the [[Bilad al-Sham]] to reconsider the validity of their marriages since they might have married in a Hanafi court (Sunni).<ref>{{cite book |last1=Deeb |first1=Lara |last2=Nalbaltian |first2=Tsolin |last3=Sbaiti |first3=Nadya |title=Practicing sectarianism: archival and ethnographic interventions on Lebanon |date=2022 |publisher=Stanford University Press |location=Stanford, California |isbn=1-5036-3387-X |pages=37-44 |url=https://www.sup.org/books/middle-east-studies/practicing-sectarianism}}</ref> So, even though discussions on this topic on the level of the [[ulama]] make it seem like there are apparent boundaries between Sunnism and Shi' ism, sectarian identification, at the beginning of the twentieth century, was not as immediately apparent.

In 1938, [[Allama Muhammad Taqi Qummi]] travelled to [[Cairo]] for the purpose of rebuilding/strengthening Islamic unity at [[Al-Azhar University]]. His efforts, including connecting with scholars such as [[Mahmud Shaltut]] and [[Seyyed Hossein Borujerdi]], led to the founding of [[Dar-al-Taghrib]] (community for reforming unity between Sunni and Shia Muslims).<ref name="Qummi">{{cite web|url=http://www.imamreza.net/eng/imamreza.php?id=6992|title=Allama Muhammad Taqi Qummi|publisher=Imam Reza. net|access-date=3 March 2015|archive-date=2 April 2015|archive-url=https://web.archive.org/web/20150402130511/http://www.imamreza.net/eng/imamreza.php?id=6992|url-status=live}}</ref> Another example of unity was a [[fatwā]] issued by the [[Rector (academia)|rector]] of [[Al-Azhar University]], [[Mahmud Shaltut]], recognizing [[Ja'fari jurisprudence|Shia Islamic law]] as the fifth school of Islamic law.

Khomeini endeavored to bridge the gap between Shias and Sunnis by declaring it permissible for Twelvers to pray behind Sunni imams and by forbidding criticizing the caliphs who preceded Ali—an issue that had caused much animosity between the two groups.<ref>{{Cite web|url=http://www.islamonline.net/servlet/Satellite?c=Article_C&cid=1175008835987&pagename=Zone-English-Muslim_Affairs%2FMAELayout#9|title=Frequently Asked Questions on Iran|archive-url=https://web.archive.org/web/20091107074118/http://www.islamonline.net/servlet/Satellite?c=Article_C&cid=1175008835987&pagename=Zone-English-Muslim_Affairs%2FMAELayout|archive-date=7 November 2009|url-status=dead}}</ref> He focused on issues that united Muslims – anti-Imperialism, anti-Zionism, anti-Americanism, and "the battle against outsiders" – rather than "religious questions that were likely to divide them".<ref name="Nasr, ''Shia Revival'', 2006, 137">Nasr, Vali, ''The Shia Revival'', Norton, (2006), p.137</ref> In addition, Khomeini designated the period of Muhammad's birthday celebrations from 12th to the 17th of Rabi Al-Awwal as the ''Islamic Unity Week'', (there being a gap in the dates of when Shias and Sunnis celebrate Muhammad's birthday).<ref>{{cite book|last1=Adib-Moghaddam|first1=Arshin|title=The International Politics of the Persian Gulf: A Cultural Genealogy|isbn=978-0-415-38559-6|url=https://books.google.com/books?id=g7CATDpNy-UC|date=27 September 2006|publisher=Routledge|access-date=31 December 2014|archive-date=9 October 2024|archive-url=https://web.archive.org/web/20241009090420/https://books.google.com/books?id=g7CATDpNy-UC|url-status=live}}</ref>

=====Outbreak of sectarianism===== Sunni–Shia unity did not last long after the [[Iranian revolution]], and strife between the two sects took a major upturn, the "Shia awakening and its instrumentalisation by Iran" as leading to a "very violent Sunni reaction", starting first in Pakistan before spreading to "the rest of the Muslim world, without necessarily being as violent."<ref name="Roy, Chaos, 2008, 105"/> As of 2008, "[[Azerbaijan]] is probably the only country where there are still mixed mosques and Shia and Sunnis pray together."<ref name="Roy, Chaos, 2008, 105">Roy, Olivier, ''The Politics of Chaos in the Middle East'', Columbia University Press, 2008. p. 105</ref>

Discord manifested itself in major and minor ways, from bombings that killed thousands, to cultural changes. Among the immediate causes of the violence were the Islamic revolution in Iran and the 2003 American military intervention in Iraq.<ref name="Roy, Chaos, 2008, 105" />

These led to antipathy between the Islamic Republic of Iran and the Kingdom of Saudi Arabia, who mobilized supporters against the other,<ref name="Fisher-2016"/> between Sunni [[Muhammad Zia-ul-Haq]] (president of Pakistan, and neighbor to Iran) and Shia [[Supreme Leader of Iran|Iranian supreme leader]] Ruhollah Khomeini,<ref name="Nasr, Vali 2006 p.138"/><ref name="Nasr, Vali 2006 pp.161-2"/> growth of sectarian militias,<ref name="Nasr, ''Shia Revival'', 2006, 162">Nasr, Vali, ''The Shia Revival'', Norton, (2006), p.162</ref> and the change in attitude of Sunni towards Shia from misguided brethren to heretics, a viewpoint spread not by "marginal extremists" but "senior Sunni Ulama".<ref name="Nasr, ''Shia Revival'', 2006, 164">Nasr, Vali, ''The Shia Revival'', Norton, (2006), p.164</ref>

Some Western analysts assert that the US is practicing [[divide and rule]] strategy through the escalation of Sunni-Shia conflict.

===Islamic revival=== Others ([[Martin Kramer|Martin Seth Kramer]], [[Vali Nasr]]) lay the blame for the strife at a very different source, the unintended effects of the [[Islamic revival]]. Historian [[Martin Kramer|Martin Seth Kramer]] (writing circa mid-1990s), argues that the focus on alleging "plots" by outsiders and/or claims by one side that the issue is only with an extremist group on the other side (for example [[Wahhabism]] or [[Khomeinism]]), distracts from the seriousness of the problem:{{blockquote|For most Muslims, it is no longer considered politic to dwell openly on the differences between Sunni and Shi'ite Islam. Indeed, merely to cite these differences is regarded by many as part of an imperialist plot to foment division in Islam. The new sectarianism takes a subtler form: Shi'ites profess their unity of purpose with Sunnis, but then declare that a major expression of Sunnism (in this case, Saudi Wahhabism) is a deviation from ecumenical Islam. Sunnis declare their acceptance of Shi'ites as Muslims, but then declare that a major expression of Shi'ism (in this case, Iran's revolutionary activism) constitutes a deviation from ecumenical Islam. In this manner, sectarian prejudice is insinuated, even as the unity of Islam is openly professed.<ref name="Kramer-ME"/>}}

According to scholar [[Vali Nasr]], as the Muslim world was decolonialised and [[Arab nationalism]] lost its appeal, religion filled its place. As religion became more important, so did a return to its fundamentals and a following of its finer points; differences once overlooked became deviations to be denouncing and fought, and there were many differences between Sunni and Shia. Fundamentalism blossomed and conflicts reasserted, in particular when Sunni followed the strict teachings of Sunni scholar [[Ibn Taymiyyah#Shi'a Islam|Ibn Taymiyyah]],<ref name=nasr-2006-106>Nasr, Vali, ''The Shia Revival'', Norton, 2006, pp. 106–07</ref> who considered Shia [[Apostacy in Islam|apostates]]<ref>{{cite book|editor1-last=Memon|editor1-first=Muhammad Umar|editor1-link=Muhammad Umar Memon|title=Ibn Taimiya's Struggle Against Popular Religion: With an Annotated Translation of His Kitab iqtida as-sirat al-mustaqim mukhalafat ashab al-jahim|date=1976|publisher=Walter de Gruyter|isbn=9783111662381|page=361|edition=reprint}}</ref> and who is held in high regard by Sunni [[Salafi]].

====Iranian Islamic revolution==== An indirect way the Islamic revival led to discord between the two major schools of Islam was through the Iranian Islamic revolution. The revolution was a direct result of the Islamic revival, led by an Islamist, Ayatollah Ruhollah Khomeini, who was very much in favor of Islamic unity, and "the leadership position that went with it".<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 138</ref> At first the revolution inspired and energized Islamist Muslims (both Shia and Sunni) everywhere, but it was a revolution in a predominantly Shi'i Muslim country, led by Shi'i Muslims, and serious rifts with Sunni Muslims soon developed.

The revolution changed the Shia–Sunni power equation in Muslim countries "from Lebanon to India". It aroused the traditionally subservient Shia, to the alarm of traditionally dominant and very non-revolutionary Sunni.<ref name=nasr-2006-148>Nasr, Vali, ''The Shia Revival'', Norton, (2006), pp. 148–50</ref> "Where Iranian revolutionaries saw Islamic revolutionary stirrings, Sunnis saw mostly Shia mischief and a threat to Sunni predominance."<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), pp. 143–44</ref>

Notwithstanding the desire of Iran's leader, Khomeini, for Shia–Sunni unity, as an Islamist revolutionary flush with success that had surprised Iranians as well as the rest of the world, Khomeini now sought the overthrow of unworthy governments in Muslim-majority countries (which were all Sunni regimes except for [[Ibadi Islam|Ibadi]]-led [[Oman]], Khomeini's government being the only Shi'i-led country at the time). Pro-American monarchies in particular were high on that list, and at the very top was the Kingdom of Saudi Arabia, not only a Wahhabi state with a long tradition of anti-Shi'ism, but an "American lackey" and "unpopular and corrupt dictatorship" (in his view, especially after seeing the 1979 [[Grand Mosque seizure]]), ripe for revolution, like "a ripe apple ready to fall into" their hands.<ref name="Nasr, Vali 2006 p.150">Nasr, Vali, ''The Shia Revival'', Norton, (2006), pp. 150</ref> But Saudi Arabia was also spending billions of dollars every year [[International propagation of Salafism and Wahhabism|funding]] Islamic schools, scholarships, and fellowships, mosques around the Sunni world. "Thousands of aspiring preachers, Islamic scholars, and activists from Nigeria to Indonesia went to Saudi Arabia to study, and many more joined Saudi-funded think tanks and research institutions." They "then spread throughout the Muslim world to teach" what they had learned and "work at Saudi-funded universities, schools, mosques, and research institutions."<ref name="Nasr, Vali 2006 p.155">Nasr, Vali, ''The Shia Revival'', Norton, (2006), pp. 155</ref> Khomeini's attack was opposed not only by the Saudi royal family but by its many (Sunni) fundamentalist allies and benefactors throughout the Arab world.

Another indirect effect (noted by political scientist [[Gilles Kepel]]), was that however religious the Saudi regime was already, in the immediate wake of Iran's Revolution it was motivated to further shore up its "religious legitimacy" with more strictness in religion (and with jihad in Afghanistan) to compete with the grassroots enthusiasm for Iran's Islamism.<ref name=GKJTPI2002:137>[[#GKJTPI2002|Kepel, ''Jihad'', 2002]]: p. 137</ref> But this also meant moving in a more anti-Shia religious direction because (as mentioned above) Saudi's own native Sunni school of Islam ([[Wahhabism]], like that of [[Ibn Taymiyyah#Shi'a Islam|Ibn Taymiyyah]]), did not consider Shiism part of the diversity of Islam, but a heresy to be fought. This new strictness was spread among the thousands of students in Saudi funded schools and more importantly among the international Islamist volunteers who came to training camps in Peshawar Pakistan in the 1980s to learn to fight jihad against Marxist secularists in Afghanistan and went home to fight jihad in the 1990s.

===US invasion of Iraq===

Among those blaming the US invasion of Iraq for the growth in sectarianism are Fawaz Gerges, who writes in his book ''ISIS: A History'',

<blockquote>By destroying state institutions and establishing a sectarian-based political system, the 2003 US-led invasion polarized the country along Sunni-Shia lines and set the stage for a fierce, prolonged struggle driven by identity politics. Anger against the United States was also fueled by the humiliating disbandment of the Iraqi army and the de-Baathification law, which was first introduced as a provision and then turned into a permanent article of the constitution.<ref name="NYRB-Ruthven" /></blockquote>

Malise Ruthven writes that the post invasion [[de-Ba'athification]] by the US occupiers deprived Iraq of "the officer class and administrative cadres that had ruled under Saddam Hussein, leaving the field to sectarian-based militias".<ref name="NYRB-Ruthven" /> Many of officers joined the anti-Shia [[takfiri]] [[ISIL]] group.

The US-led invasion also "tilted the regional balance of power decisively" in favor of Shia Iran, alarming Sunni and leading to talk of a "Shia Crescent".<ref name="NYRB-Ruthven" />

===Counter-revolutionary tactic===

[[Marc Lynch]] in his book ''The New Arab Wars: Uprisings and Anarchy in the Middle East'', argues that as old regimes or political forces sought to control "the revolutionary upsurge" of the [[Arab Spring]], [[sectarianism]] became "a key weapon" to undermine unity among the anti-regime masses. Christians were pitted "against Muslims in Egypt, Jordanians against Palestinians in Jordan, and, above all, Sunnis against Shi'ites wherever possible."<ref name="NYRB-Ruthven" />

==Relations by country and region== === Iraq === {{Main|Shia Islam in Iraq|Sunni Islam in Iraq}}

Shia–Sunni discord in Iraq starts with disagreement over the relative population of the two groups. The governing regimes of Iraq were composed mainly of Sunnis for nearly a century until the 2003 Iraq War, but according to most sources, the majority of the population is Shia. The CIA's ''[[The World Factbook|World Factbook]]'', estimates Shia [[Arab Muslims]] as making up 60% of Iraqis, and Sunni [[muslims]] 37%.<ref>{{cite web|url=https://www.cia.gov/the-world-factbook/countries/iraq/|title=The World Factbook|publisher=Central Intelligence Agency|date=12 January 2022|access-date=24 January 2021|archive-date=10 January 2021|archive-url=https://web.archive.org/web/20210110010834/https://www.cia.gov/the-world-factbook/countries/iraq|url-status=dead}}</ref> However, Sunni are split ethnically among [[Arab people|Arabs]], [[Kurdish people|Kurds]] and [[Iraqi Turkmens|Turkmen]].

The British, having put down a Shia rebellion against their rule in the 1920s, "confirmed their reliance on a corps of Sunni ex-officers of the collapsed Ottoman Empire". The British colonial rule ended after the Sunni and Shia united against it.<ref>''The Arab Shia'', p. 46</ref>

The Shia suffered indirect and direct [[Persecution of Shia Muslims|persecution]] under post-colonial Iraqi governments since 1932, erupting into [[Iraqi Shia revolts 1935–1936|full-scale rebellions]] in 1935 and 1936. Shia were also persecuted during the [[Ba'ath Party]] rule, especially under [[Saddam Hussein]]. It is said that every Shia clerical family of note in Iraq had tales of torture and murder to recount.<ref>Nasr, Vali, ''The Shia Revival'', (Norton, 2006), p. 187</ref> In 1969 the son of Iraq's highest Shia Ayatollah [[Muhsin al-Hakim]] was arrested and allegedly tortured. From 1979 to 1983 Saddam's regime executed 48 major Shia clerics in Iraq.<ref>according to pro-Khomeini author Abdel-Majid Trab Zemzem, in his book ''The Iraq-Iran War, Islam and Nationalisms'', translated from the French by Zinab Mohammad, United States Publishing Company, 1986, pp. 42–43</ref> They included Shia leader [[Mohammad Baqir al-Sadr]] and his sister. Tens of thousands of Iranians and Arabs of Iranian origin were expelled in 1979 and 1980 and a further 75,000 in 1989.<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 110</ref>

The Shia openly [[1991 uprisings in Iraq|revolted against Saddam]] following the [[Gulf War]] in 1991 and were encouraged by Saddam's defeat in Kuwait and by simultaneous Kurdish uprising in the north. However, Shia opposition to the government was brutally suppressed, resulting in some 50,000 to 100,000 casualties and successive repression by Saddam's forces.<ref>{{cite news|last1=Black|first1=Ian|title='Chemical Ali' on trial for brutal crushing of Shia uprising|url=https://www.theguardian.com/world/2007/aug/22/iraq.ianblack|access-date=17 May 2017|work=The Guardian|date=22 August 2007|archive-date=29 September 2018|archive-url=https://web.archive.org/web/20180929023307/https://www.theguardian.com/world/2007/aug/22/iraq.ianblack|url-status=live}}</ref>

In addition to Iran, Iraq has emerged as a major Shia government when the Twelvers achieved political dominance in 2005 under American occupation. The two communities have often remained separate, mingling regularly only during the Hajj pilgrimage in Mecca. In some countries like Iraq, Syria, Kuwait and Bahrain, communities have mingled and intermarried.

Iran is unique in the Muslim world because its population is overwhelmingly more Shia than Sunni (Shia constitute around 90% of the population) and because its constitution is [[Theocracy|theocratic]] republic based on rule by a Shia jurist.

The founder of the [[Islamic republic]], Ayatollah Ruhollah Khomeini, supported good Sunni–Shia relations. However tension developed between Sunnis and Shia as a result of clashes over Iranian pilgrims and Saudi police at the [[hajj]].<ref name=IRIvKSA>{{cite book|last=Nasr|first=Seyyed Vali Reza|title=The Shia Revival: How Conflicts Within Islam Will Shape the Future|date=2006|publisher=W.W.

Soon after the 1979 revolution, Sunni leaders from Kurdistan, Balouchistan, and [[Khorasan province|Khorassan]], set up a new party known as ''Shams'', which is short for Shora-ye Markaz-e al Sunaat, to unite Sunnis and lobby for their rights. But six months after that they were closed down, bank accounts suspended and had their leaders arrested by the government on charges that they were backed by Saudi Arabia and Pakistan.<ref name="iran.org" />

Members of the 'Balochistan Peoples Front' claim that Sunnis are systematically discriminated against educationally by denial of places at universities, politically by not allowing Sunnis to be army generals, ambassadors, ministers, prime minister, or president, religiously insulting Sunnis in the media, economic discrimination by not giving import or export licenses for Sunni businesses while the majority of Sunnis are left unemployed.<ref>[http://balochistanpeoplesfront.blogspot.com/2006/12/shia-equality-or-shia-supremacy.html Shia equality or Shia supremacy?

There has been a low level resistance in mainly Sunni Iranian Balouchistan against the regime for several years. Official media refers to the fighting as armed clashes between the police and "bandits," "drug-smugglers," and "thugs," to disguise what many believe is essentially a political-religious conflict. [[Islamic Revolutionary Guard Corps|Revolutionary Guards]] have stationed several brigades in Balouchi cities, and have allegedly tracked down and assassinated Sunni leaders both inside Iran and in neighboring Pakistan. In 1996 a leading Sunni, Abdulmalek Mollahzadeh, was gunned down by hitmen, allegedly hired by Tehran, as he was leaving his house in Karachi.<ref>[http://www.iran.org/news/TIB_970602.htm Interview with Molavi Ali Akbar Mollahzadeh] {{Webarchive|url=https://web.archive.org/web/20241009090921/http://www.iran.org/news/TIB_970602.htm |date=9 October 2024 }} The Iran Brief, Issue Number 35, 2 June 1997</ref>

=== Syria === {{Main|Islam in Syria}}

Syria is approximately three-quarters Sunni,<ref>{{cite web|url=https://www.cia.gov/the-world-factbook/countries/syria/|title=The World Factbook|publisher=Central Intelligence Agency|date=10 January 2022|access-date=24 January 2021|archive-date=9 January 2021|archive-url=https://web.archive.org/web/20210109103654/https://www.cia.gov/the-world-factbook/countries/syria/|url-status=dead}}</ref> but its government is predominantly [[Alawite]], a Shia sect that makes up less than 13% of the population. Under [[Hafez al-Assad]], Alawites dominated the [[Arab Socialist Ba'ath Party – Syria Region|Arab Socialist Ba'ath Party]], a secular Arab nationalist party which had ruled Syria under a state of emergency from 1963 to 2011. Alawites are often considered a form of Shia Islam, that differs somewhat from the larger Twelver Shia sect.<ref>{{cite web|url=http://dictionary.reference.com/browse/alawi|title=Define Alawite at Dictionary.com|work=Dictionary.com}}</ref>

During the 20th century, an [[Islamic uprising in Syria]] occurred with sectarian religious overtones between the Alawite-dominated Assad government and the [[Islamism|Islamist]] Sunni [[Muslim Brotherhood]], culminating with the 1982 [[1982 Hama massacre|Hama massacre]]. An estimated 10,000 to 40,000 Syrians, mostly civilians, were killed by [[Syrian Armed Forces|Syrian military]] in the city. During the uprising, the Sunni Muslim Brotherhood [[Aleppo Artillery School massacre|attacked military cadets]] at an artillery school in [[Aleppo]], performed car bomb attacks in Damascus, as well as bomb attacks against the government and its officials, including Hafez al-Assad himself, and had killed several hundred.

How much of the conflict was sparked by Sunni versus Shia divisions and how much by Islamism versus secular-Arab-nationalism, is in question, but according to scholar Vali Nasr the failure of the Ayatollah Khomeini and the Islamic Republic of Iran to support the Muslim Brotherhood against the Baathists "earned [Khomeini] the Brotherhood's lasting contempt." It proved to the satisfaction of the Brotherhood that sectarian loyalty trumped Islamist solidarity for Khomeini and eliminated whatever appeal Khomeini might have had to the MB movement as a pan-Islamic leader.<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 154</ref>

====Syria Civil War==== {{Main|Syrian Civil War}}

The [[Syrian Civil War]], though it started as a political conflict, developed into a struggle between the Alawite-dominated Army and government on the one hand, and the mainly Sunni rebels and former members of the regular army on the other. The casualty toll of the war's first three years has exceeded that of Iraq's decade-long conflict, and the fight has "amplified sectarian tensions to unprecedented levels".<ref name=CFR-SSD /> Rebel groups with 10,000s of Sunni Syrian fighters such as [[Ahrar ash-Sham]], the Islamic Front, and al-Qaeda's [[al-Nusra Front]], employ anti-Shia rhetoric and foreign Arab and Western Sunni fighters have joined the rebels. On the other side Shia from Hezbollah in Lebanon and from Asaib Ahl al-Haq and Kata'ib Hezbollah militias from Iraq have backed the Syrian government.<ref name=CFR-SSD /> "Even Afghan Shia refugees in Iran", driven from Afghanistan by Sunni extremism, have "reportedly been recruited by Tehran for the war in Syria".<ref name=CFR-SSD />

The Saudi conflict of Shia and Sunni extends beyond the borders of the kingdom because of international Saudi "[[Petro-Islam]]" influence.

Relations between the Shia and the Wahhabis are inherently strained because the Wahhabis consider the rituals of the Shia to be the epitome of ''shirk'', or [[polytheism]]. In the late 1920s, the [[Ikhwan]] ([[Ibn Saud of Saudi Arabia|Ibn Saud's]] fighting force of converted Wahhabi [[Bedouin]] Muslims) were particularly hostile to the Shia and demanded that Abd al Aziz forcibly convert them. In response, Abd al Aziz sent Wahhabi missionaries to the [[Eastern Province, Saudi Arabia|Eastern Province]], but he did not carry through with attempts at forced conversion. In recent decades the late leading Saudi cleric, [[Ibn Baz]], issued fatwa denouncing Shia as apostates, and according to Shia scholar Vali Nasr " Ibn Jibrin, a high-ranking Salafi cleric, even sanctioned the killing of Shia,<ref name="Nasr, Vali 2006 p.236" /> a call that was reiterated by Wahhabi religious literature as late as 2002."<ref>Toby Jones, 'The Iraq Effect in Saudi Arabia,` ''Middle East Report'', 237, Winter 2005, p. 24</ref>

Government policy has been to allow Shia their own mosques and to exempt Shia from [[Salafi]] inheritance practices.{{citation needed|date=March 2016}} Nevertheless, Shia have been forbidden all but the most modest displays on their principal festivals, which are often occasions of sectarian strife in the Persian Gulf region, with its mixed Sunni–Shia populations.<ref name="lcweb2.loc.gov" />

As of 2006 four of the 150 members of Saudi Arabia's "handpicked" parliament were Shia, but no city had a Shia mayor or police chief, and none of the 300 girls schools for Shia in the Eastern Province had a Shia principal.

Forced into exile in the 1970s, Saudi Shia leader [[Hassan al-Saffar]] is said to have been "powerfully influenced" by the works of Sunni Islamists of the Muslim Brotherhood and [[Jamaat-e-Islami Pakistan|Jamaat-e-Islami]] and by their call for Islamic revolution and an Islamic state.<ref>"The Shiite Question in Saudi Arabia", ''Middle East Report'', 45, International Crisis Group, 2005, p. 3. Quoted in Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 117</ref>

Following the 1979 Iranian Revolution, Shia in Hasa ignored the ban on mourning ceremonies commemorating Ashura. When police broke them up three days of rampage ensued—burned cars, attacked banks, looted shops—centered around Qatif. At least 17 Shia were killed. In February 1980 disturbances were "less spontaneous" and even bloodier.<ref>Wright, Robin, ''Sacred Rage'', Simon and Schuster, (2001), p. 150</ref> Meanwhile, broadcasts from Iran in the name of the Islamic Revolutionary Organization attacked the monarchy, telling listeners, "Kings despoil a country when they enter it and make the noblest of its people its meanest ... This is the nature of monarchy, which is rejected by Islam."<ref>BBC monitoring service from March 1980 quoted in [[William B. Quandt]], ''Saudi Arabia in the 1980s'', Brookings Institution, 1981, pp. 39–40</ref>

By 1993, Saudi Shia had abandoned uncompromising demands and some of al-Saffar's followers met with [[Fahd of Saudi Arabia|King Fahd]] with promises made for reform. In 2005 the new [[Abdullah of Saudi Arabia|King Abdullah]] also relaxed some restrictions on the Shia.<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), pp. 238, 240</ref> However, Shia continue to be arrested for commemorating Ashura as of 2006.<ref>[[Human Rights Watch]] [http://hrw.org/englishwr2k7/docs/2007/01/11/saudia14717.htm Saudi Arabia – Events of 2006] {{webarchive|url=https://web.archive.org/web/20070225200425/http://hrw.org/englishwr2k7/docs/2007/01/11/saudia14717.htm |date=25 February 2007 }}</ref> In December 2006, amidst escalating tensions in Iraq, 38 high ranking Saudi clerics called on Sunni Muslims around the world to "mobilise against Shiites".<ref>{{cite web|url=http://www.dailytimes.com.pk/default.asp?page=2006%5C12%5C12%5Cstory_12-12-2006_pg4_8|title=Your Right To Know|work=Daily Times|access-date=6 May 2016|archive-date=12 January 2012|archive-url=https://web.archive.org/web/20120112173924/http://www.dailytimes.com.pk/default.asp?page=2006%5C12%5C12%5Cstory_12-12-2006_pg4_8|url-status=live}}</ref> A year later, Shia Grand Ayatollah [[Naser Makarem Shirazi]] is reported to have responded: {{Blockquote|The Wahhabis ignore the occupation of Islam's first [[Qibla]]h by Israel, and instead focus on declaring [[Takfir]]ing fatwas against Shia.<ref>Press release by [[Iranian Students' News Agency]]: [http://www.isna.ir/Main/NewsView.aspx?ID=News-865630&Lang=P www.isna.ir] {{webarchive |url=https://web.archive.org/web/20071222034411/http://www.isna.ir/Main/NewsView.aspx?ID=News-865630&Lang=P |date=22 December 2007 }}</ref>}}

====Al-Qaeda==== Some Wahabi groups, often labeled as ''[[takfiri]]'' and sometimes linked to Al-Qaeda, have even advocated the persecution of the Shia as heretics.<ref>[https://web.archive.org/web/20051024004108/http://english.aljazeera.net/NR/exeres/407AAE91-AF72-45D7-83E9-486063C0E5EA.htm Al-Zarqawi declares war on Iraqi Shia] aljazeera.net, 14 September 2005</ref> Such groups have been allegedly responsible for violent attacks and suicide bombings at Shi'a gatherings at mosques and shrines, most notably in Iraq during the Ashura mourning ceremonies where hundreds of Shia were killed in coordinated suicide bombings,<ref>[http://news.bbc.co.uk/2/hi/middle_east/4276367.stm Blasts target Iraq's Shia Muslims on the eve of Ashura] {{Webarchive|url=https://web.archive.org/web/20081219131913/http://news.bbc.co.uk/2/hi/middle_east/4276367.stm |date=19 December 2008 }} 18 February 2005</ref><ref>[http://www.rediff.com/news/2005/sep/16iraq.htm Latest Iraq blast targets Shia mosque, September 16, 2005] {{Webarchive|url=https://web.archive.org/web/20241009091435/https://www.rediff.com/news/2005/sep/16iraq.htm |date=9 October 2024 }} "Abu Musab al-Zarqawi, vowed to wage an 'all-out war' on the country's Shia majority"</ref><ref>"[http://www.signonsandiego.com/uniontrib/20050918/news_7n18iraq.html Four days after al-Qaeda in Iraq declared all-out war on the Shiite majority, more than 250 people have been killed] {{Webarchive|url=https://web.archive.org/web/20241009091435/https://www.sandiegouniontribune.com/ |date=9 October 2024 }}" San Diego Union Tribune, 18 September 2005</ref> but also in Pakistan and Afghanistan. However, in a video message, Al-Qaeda deputy Dr [[Ayman al-Zawahiri]] directed Abu Musab al-Zarqawi, of Al-Qaeda in Iraq, not to attack civilian targets but to focus on the occupation troops. His call seems to have been ignored, or swept away in the increasing tensions of Iraq under occupation.

====Hajj==== Every year, Muslims from all over the world attend the hajj pilgrimage in Mecca in Western Saudi Arabia. Shia had complained off and on of mistreatment by the Sunnis who ran Mecca and the hajj ceremonies. Following the advent of Saudi-Wahhabi rule over Mecca in 1924 tensions between Shia and Sunni increased. To the fury of Shia Muslims, the Wahhabi Sunnis demolished domes in the [[Al-Baqi Cemetery|cemetery of Al-Baqi]], near the Medina, "the reputed resting place of the Prophet Muhammad's daughter Fatima and four of the Twelve Imams".<ref name="Kramer-ME"/> In 1943, a Saudi religious judge ordered the beheading of an Iranian pilgrim "for allegedly defiling the Great Mosque with excrement" smuggled into "the mosque in his pilgrim's garment". Saudi public opinion considered the crime unsurprising and the punishment just, but the Iranians were furious and demanded payment of an indemnity. Tensions lowered again during the 1960s, when pious/tradionalist Muslims set aside differences in the face of the rising popularity of Nasser's leftist Arab nationalism. Pilgrims from Iran (mostly Shia) rose in number from 12,000 in 1961 to 57,000 in 1972.<ref name="Kramer-ME"/>

In 1987, about seven years after the [[Iranian revolution]], Mecca became a site "[[1987 Mecca incident|of unprecedented carnage]]" when demonstrating Shia Iranian pilgrims clashed with Saudi security forces and over four hundred were killed. The Saudis and their supporters claimed violent Iranian demonstrators crushed themselves to death in a stampede of their own making. The Iranians and their sympathizers claimed the Saudis had conspired to provoke and then shoot Iranian pilgrims. The pilgrimage to Mecca, where violence is forbidden, had itself become a point of confrontation between rival visions of Islam.<ref name="Kramer-ME"/>

=== Lebanon === Though sectarian tensions in Lebanon were at their height during the [[Lebanese Civil War]], the Shia–Sunni relations were not the main conflict of the war. The Shia party of [[Hezbollah]] emerged in Lebanon during the Lebanese Civil War as one of the strongest forces following the Israeli withdrawal in the year 2000, and the collapse of the [[South Lebanese Army]] in the South. The tensions blew into a [[2008 conflict in Lebanon|limited warfare]] between Shia dominated and Sunni dominated political alliances in 2008.

With the eruption of the Syrian Civil War, [[Bab al-Tibbaneh, Jabal Mohsen clashes|tensions]] increased between the Shia-affiliated Alawites and Sunnis of Tripoli, erupting twice into deadly violence—in June 2011, and the [[2012 sectarian clashes in Lebanon|second time in February 2012]]. The Syrian war has affected Hezbollah, which was once lauded by both Sunnis and Shi'ites for its battles against Israel, but now has lost support from many Sunnis for its military assistance to Syrian President Bashar al-Assad.

=== Jordan === {{Main|Islam in Jordan}}

Although the country of Jordan is 95% Sunni and has not seen any Shia–Sunni fighting within, it has played a part in the recent Shia-Sunni strife. It is the home country of anti-Shia insurgent [[Raed Mansour al-Banna]], who died perpetrating one of Iraq's worst suicide bombings in the city of Al-Hillah. Al-Banna killed 125 Shia and wounded another 150 in the [[2005 Al Hillah bombing]] of a police recruiting station and adjacent open air market. In March 2005 [[Salt, Jordan|Salt]], al-Banna's home town, saw a three-day wake for al-Banna who Jordanian newspapers and celebrants proclaimed a [[Shahid|martyr]] to Islam, which by definition made the Shia victims "infidels whose murder was justified." Following the wake Shia mobs in Iraq attacked the Jordanian embassy on 20 March 2005.

=== Yemen === {{Main|Islam in Yemen}}

{{See also|Human rights in Yemen|Religion in Yemen}} Muslims in Yemen include the majority Shafi'i (Sunni) and the minority Zaidi (Shia). Zaidi are sometimes called "Fiver Shia" instead of Twelver Shia because they recognize the first four of the Twelve Imams but accept [[Zayd ibn Ali]] as their "Fifth Imām" rather than his brother [[Muhammad al-Baqir]]. Shia–Sunni conflict in Yemen involves the [[Houthi insurgency]] in northern Yemen.<ref name="scribd.com" />

Both Shia and Sunni dissidents in Yemen have similar complaints about the government—cooperation with the American government and an alleged failure to following Sharia law<ref>Yemen Facing Insurgency on Two Fronts, By Stephen Ulph (see above)</ref>—but it's the Shia who have allegedly been singled out for government crackdown.

During and after the US-led invasion of Iraq, members of the Zaidi-Shia community protested after Friday prayers every week outside mosques, particularly the [[Great Mosque of Sana'a|Grand Mosque]] in [[Sana'a]], during which they shouted anti-US and anti-Israeli slogans, and criticised the government's close ties to America.<ref>[http://web.amnesty.org/library/Index/ENGMDE310012007?open&of=ENG-366 Amnesty Report] {{webarchive|url=https://web.archive.org/web/20070217133641/http://web.amnesty.org/library/Index/ENGMDE310012007?open&of=ENG-366 |date=17 February 2007 }}</ref> These protests were led by ex-parliament member and Imam, Bader Eddine al-Houthi.<ref>{{Cite web|url=http://www.arabicnews.com/ansub/Daily/Day/040709/2004070905.html|archive-url=https://web.archive.org/web/20070930200815/http://www.arabicnews.com/ansub/Daily/Day/040709/2004070905.html|url-status=dead|title=Yemeni President: al-Houthi is an ill man, mentally abnormal|archive-date=30 September 2007}}</ref> In response the Yemeni government has implemented a campaign to crush to the Zaidi-Shia rebellion"<ref>[http://news.bbc.co.uk/2/hi/middle_east/3863463.stm Clashes 'leave 118 dead' in Yemen] {{Webarchive|url=https://web.archive.org/web/20171012082812/http://news.bbc.co.uk/2/hi/middle_east/3863463.stm |date=12 October 2017 }}, [[BBC]] report</ref> and harass journalists.<ref>Yemen: [http://www.amnestyusa.org/countries/yemen/document.do?id=ENGMDE310142005 Harassment of journalists must stop] {{Webarchive|url=https://web.archive.org/web/20061202124308/http://www.amnestyusa.org/countries/yemen/document.do?id=ENGMDE310142005 |date=2 December 2006 }}</ref>

Pakistan's citizens have had serious Shia-Sunni discord. Almost 80–90% of Pakistan's Muslim population is Sunni, with 10–20% being Shia, but this Shia minority forms the second largest Shia population of any country,<ref>Nasr, Vali, ''The Shia Revival'' (Norton), 2006, p. 160</ref> larger than the Shia majority in Iraq.

====Background==== Some see a precursor of Pakistani Shia–Sunni strife in the April 1979 execution of deposed President Zulfikar Ali Bhutto on questionable charges by [[Islamic fundamentalism|Islamic fundamentalist]] General [[Muhammad Zia-ul-Haq]]. Ali Bhutto was Shia, Zia ul-Haq a Sunni.<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 89</ref>

[[Zia-ul-Haq's Islamization]] that followed was resisted by Shia who saw it as "Sunnification" as the laws and regulations were based on Sunni ''[[fiqh]]''. In July 1980, 25,000 Shia protested the [[Islamization]] laws in the capital [[Islamabad]]. Further exacerbating the situation was the dislike between Shia leader Imam Khomeini and General Zia ul-Haq.<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), pp. 161–62</ref>

Shia formed student associations and a Shia party, Sunni began to form sectarian militias recruited from Deobandi and [[Ahl al-Hadith]] madrasahs. Preaching against the Shia in Pakistan was cleric [[Israr Ahmed]]. [[Manzoor Nomani]], a senior Indian cleric with close ties to Saudi Arabia published a book entitled ''Iranian Revolution: Imam Khomeini and Shiism''. The book, which "became the gospel of Deobandi militants" in the 1980s, attacked Khomeini and argued the excesses of the Islamic revolution were proof that Shiism was not the doctrine of misguided brothers, but beyond the Islamic pale.<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 164</ref>

Anti-Shia groups in Pakistan include the [[Lashkar-e-Jhangvi]] and [[Sipah-e-Sahaba Pakistan]], offshoots of the [[Jamiat Ulema-e-Islam]] (JUI). The groups demand the expulsion of all Shia from Pakistan and have killed hundreds of Pakistani Shia between 1996 and 1999.<ref name="Rashid, Taliban 2000, p.194">Rashid, ''Taliban'' (2000), p. 194</ref> As in Iraq they "targeted Shia in their holy places and mosques, especially during times of communal prayer."<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 166</ref> From January to May 1997, Sunni terror groups assassinated 75 Shia community leaders "in a systematic attempt to remove Shia from positions of authority."<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 167</ref> Lashkar-e-Jhangvi has declared Shia to be "American agents" and the "near enemy" in global jihad.<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 168</ref>

An example of an early Shia–Sunni ''[[Fitna (word)|fitna]]'' shootout occurred in [[Kurram Valley|Kurram]], one of the [[Federally Administered Tribal Areas|tribal agencies]] of the [[Khyber Pakhtunkhwa|Northwest Pakistan]], where the [[Pashtun people|Pushtun]] population was split between Sunnis and Shia. In September 1996 more than 200 people were killed when a gun battle between teenage Shia and Sunni escalated into a communal war that lasted five days. Women and children were kidnapped and gunmen even executed out-of-towners who were staying at a local hotel.<ref>Kaplan, Robert, ''Soldiers of Allah: With Islamic Warriors in Afghanistan and Pakistan'', New York: Vintage Departures, 2001, p. 242</ref>

"Over 80,000 Pakistani Islamic militants have trained and fought with the Taliban since 1994. They form a hardcore of Islamic activists, ever-ready to carry out a similar Taliban-style Islamic revolution in Pakistan.", according to Pakistani journalist [[Ahmed Rashid]].<ref name="Rashid, Taliban 2000, p.194" />

Shia–Sunni strife in Pakistan is strongly intertwined with that in Afghanistan. The anti-Shia Afghan [[Taliban]] regime helped anti-Shia Pakistani groups and vice versa. Lashkar-e-Jhangvi and Sipah-e-Sahaba Pakistan, have sent thousands of volunteers to fight with the Taliban regime and "in return the Taliban gave sanctuary to their leaders in the Afghan capital of Kabul."<ref>Rashid, ''Taliban'' (2000), p. 263</ref>

Shia–Sunni strife inside of Afghanistan has been between the Sunni Taliban and Shia Afghans, primarily the [[Hazara people|Hazara]] ethnic group—a function of the puritanical religious character of the Taliban and their "traditional [[Pashtuns|Pashtun]] biases against Shias".<ref>Nasr, Vali, ''The Shia Revival'', Norton, (2006), p. 157</ref>
