{{Religion in Turkey}}
{{Islam by country}}

[Islam](/source/Islam) is by far the most practiced religion in [Turkey](/source/Turkey). Most [Turkish people](/source/Turkish_people) are [Sunni](/source/Sunni) Muslims, and most of them belong to the [Hanafi](/source/Hanafi) school of jurisprudence. Smaller numbers belong to the [Alevi](/source/Alevi), [Ja'fari](/source/Ja'fari) and [Alawite](/source/Alawite) minorities. The established presence of Islam in the region that now constitutes modern Turkey dates back to the second half of the 11th century, when the [Seljuks](/source/Seljuk_Empire) started expanding into [eastern Anatolia](/source/Eastern_Anatolia_Region).<ref>{{Cite journal|last=Aktas|first=Vahap|date=2014-01-01|title=Islamization of Anatolia and the Effects of Established Sufism (Orders)|url=https://doi.org/10.1080/09720073.2014.11891424|journal=The Anthropologist|volume=17|issue=1|pages=147–155|doi=10.1080/09720073.2014.11891424|s2cid=55540974|issn=0972-0073|access-date=27 October 2020|archive-date=22 November 2021|archive-url=https://web.archive.org/web/20211122132935/https://www.tandfonline.com/doi/abs/10.1080/09720073.2014.11891424|url-status=live|url-access=subscription}}</ref>

While official records indicate the population of Turkey to be 99.8% Muslim,{{efn|name=thirtythree|These are based on the existing religion information written on every citizen's national ID card, automatically passed on from the parents to every newborn, and do not necessarily represent individual choice.

Therefore, the official number of Muslims also includes people with no religion; converted from Islam to a different religion than Islam; and anyone who is of a different religion than their parents but hasn't applied for a change of their individual records.}} most surveys estimate the percentage to be around 90 to 95%.<ref name="nsp.marmara.edu.tr">{{Cite book |last=Nişancı |first=Zübeyir |editor1=Ayşe Betül Aydın |editor2=Hatice Nur Keskin |date=21 March 2023 |title=Faith and Religiosity in Türkiye |url=https://nsp.marmara.edu.tr/dosya/nsp/Resimler/Faith-and-Religiosity-in-T%C3%BCrkiye-Z%C3%BCbeyir-Ni%C5%9Fanc%C4%B1.pdf |archive-url=https://web.archive.org/web/20230420223018/https://nsp.marmara.edu.tr/dosya/nsp/Resimler/Faith-and-Religiosity-in-T%C3%BCrkiye-Z%C3%BCbeyir-Ni%C5%9Fanc%C4%B1.pdf |archive-date=20 April 2023 |access-date=23 Aug 2023 |isbn=978-1-64205-906-9 |publisher=[Marmara University](/source/Marmara_University) |url-status=live |language=en}}</ref><ref>{{cite web | url=https://www.worldvaluessurvey.org/WVSDocumentationWV7.jsp | title=WVS Database }}</ref><ref>

Whether "Turkish Islam" is more "moderate and pluralistic" compared to other Islamic societies is disputed, with a majority claiming this to be true. Reasons given for this statement include: the state constitution not containing any references to Islam, alcohol consumption being prevalent, and instead of promoting religious activities there was a state-imposed [ban on Islamic attire](/source/Headscarf_controversy_in_Turkey) and [restrictions on religious activities](/source/Atat%C3%BCrk's_reforms) until the late 2010s.<ref>{{citation|last1=Rabasa|first1=Angel|last2=Larrabee|first2=F.

During the Muslim conquests of the 7th and early 8th centuries, [Arab armies](/source/Rashidun_army) established the [Islamic Empire](/source/Caliphate). The [Umayyad Caliphate](/source/Umayyad_Caliphate) continued the spread of [Islam](/source/Islam). The [Islam](/source/Islam)ic [Golden Age](/source/Golden_Age) was soon inaugurated by the middle of the 8th century by the ascension of the [Abbasid](/source/Abbasid) [Caliphate](/source/Caliphate) and the transfer of the capital from [Damascus](/source/Damascus) to [Baghdad](/source/Baghdad).<ref name="Vartan">Gregorian, Vartan. ''Islam: A Mosaic, Not a Monolith'', Brookings Institution Press, 2003, pp. 26–38 {{ISBN|0-8157-3283-X}}</ref>

The later period saw initial expansion and the capture of [Crete](/source/Crete) (840). The Abbasids soon shifted their attention towards the East. During the later fragmentation of the Abbasid rule and the rise of their [Shiite](/source/Shiite) rivals the [Fatimid](/source/Fatimid)s and [Buyid](/source/Buyid)s, a resurgent Byzantium recaptured [Crete](/source/Crete) and [Cilicia](/source/Cilicia) in 961, [Cyprus](/source/Cyprus) in 965, and pushed into the Levant by 975. The Byzantines successfully contested with the [Fatimid](/source/Fatimid)s for influence in the region until the arrival of the [Seljuk Turks](/source/Seljuk_dynasty) who first allied with the Abbasids and then ruled as the ''de facto'' rulers.

In 1068, [Alp Arslan](/source/Alp_Arslan) and allied [Turkoman](/source/Turkoman_(ethnonym)) tribes recaptured many Abbasid lands and even invaded Byzantine regions, pushing further into [eastern](/source/Eastern_Anatolia_Region) and [central Anatolia](/source/Central_Anatolia_Region) after a major victory at the [Battle of Manzikert](/source/Battle_of_Manzikert) in 1071. The disintegration of the Seljuk dynasty resulted in the rise of subsequent, smaller, rival [Turkic kingdoms](/source/Anatolian_beyliks) such as the [Danishmends](/source/Danishmends), the [Sultanate of Rum](/source/Sultanate_of_Rum), and various [Atabeg](/source/Atabeg)s who contested the control of the region during the [Crusade](/source/Crusade)s and incrementally expanded across Anatolia until the [rise of the Ottoman Empire](/source/rise_of_the_Ottoman_Empire).

Beginning in the 12th century, new waves of Turkic migrants arrived, many of whom belonging to [Sufi](/source/Sufi) orders. Some of these migrants later went on to incorporate [heterodox](/source/Heterodoxy) beliefs. One Sufi order that appealed to Turks in [Anatolia](/source/Anatolia) was the [Safaviyya](/source/Safaviyya), an order that was originally Sunni and non-political, but later became both [Shi'a](/source/Shia_Islam) and politically based in northwest [Iran](/source/Iran). During the 14th and 15th centuries, the [Safavid](/source/Safavid_order) and similar orders such as the [Bektaşi](/source/Bekta%C5%9Fi) became rivals of the [Ottomans](/source/Ottoman_Empire)—who were [orthodox](/source/Orthodoxy) Sunni Muslims—for political control of eastern Anatolia. Although the Bektaşi order became accepted as a [sect](/source/sect) of orthodox Sunni Muslims, they did not abandon their heterodox beliefs. In contrast, the Safavids eventually conquered Iran, spread their beliefs, and became proponents of orthodox [Twelver Shi'a Islam](/source/Twelver_Shi'ism).

The conquest of the Byzantine capital of [Constantinople](/source/Constantinople) (modern day [Istanbul](/source/Istanbul)) in 1453 enabled the Ottomans to consolidate their empire in Anatolia and [Thrace](/source/Thrace). The Ottomans later revived the title of [caliph](/source/Caliphate) during the reign of [Selim I](/source/Selim_I). Despite the absence of a formal institutional structure, Sunni religious functionaries continued to play an important political role. In theory, the codified system of [sharia](/source/sharia) regulated all aspects of everyday life, at least for Muslim subjects of the empire. The head of the [judiciary](/source/judiciary) ranked directly below the sultan, and was second in power only to the grand [vizier](/source/vizier). Early in the Ottoman period, the office of grand [mufti](/source/mufti) of Istanbul evolved into that of ''[Şeyhülislam](/source/List_of_Sheikh-ul-Islams_of_the_Ottoman_Empire)'' (shaykh, or "leader of Islam"), which had ultimate jurisdiction over all the courts in the empire and consequently exercised authority over the interpretation and application of sharia. Legal opinions pronounced by the Şeyhülislam were considered definitive interpretations.

[[File:Mustafa Kemal Paşa ve Abdurrahman Kamil Efendi (1930).jpg|thumb|[President](/source/President_of_Turkey) [Mustafa Kemal Pasha](/source/Mustafa_Kemal_Atat%C3%BCrk) and [Mufti](/source/Mufti) Abdurrahman Kamil Effendi in [Amasya](/source/Amasya) (1930)]]

The [secularization of Turkey](/source/Secularism_in_Turkey) started during the last years of the [Ottoman Empire](/source/Ottoman_Empire) and was a prominent feature of [Atatürk's reforms](/source/Atat%C3%BCrk's_reforms). [Secularism](/source/Secularism) ''(or [laiklik](/source/laiklik))'' became one of the "[Six Arrows](/source/Six_Arrows)" of Atatürk's program for remaking Turkey. Under his leadership, in 1922, the [caliphate](/source/caliphate) was abolished, and the secular power of religious authorities and functionaries was reduced and eventually eliminated. Religious foundations were nationalized. The influential and popular orders of the [dervish](/source/dervish) brotherhoods ([Tariqa](/source/Tariqa)) were also suppressed.

In 1922, the new nationalist regime abolished the Ottoman sultanate, as well as the caliphate in 1924 - the religious office that Ottoman sultans had held for four centuries. Thus, for the first time in Islamic history, no ruler claimed spiritual leadership of Islam.

Atatürk and his associates abolished certain religious practices and institutions and generally questioned the value of religion, preferring to place their trust in [science](/source/science). They regarded organized religion as an [anachronism](/source/anachronism) and contrasted it unfavorably with "civilization", which to them meant a [rationalist](/source/Rationalism), secular culture. Unlike in the West, the establishment of secularism in Turkey was not a gradual process of separation of mosque and state.

In the Ottoman Empire, all residents, at least theoretically, had been subject to traditional religious law, and Sunni religious organizations had been part of the state structure. However, the state usually had authority over the [clergy](/source/clergy) and religious law (e.g. many Sultans are known to change [Şeyhülislams](/source/List_of_Sheikh-ul-Islams_of_the_Ottoman_Empire), who do not approve of state politics). When the reformers of the early 1920s opted for a secular state, they removed religion from the sphere of public policy and restricted it to exclusively that of [personal morals](/source/Morality), behavior, and faith. Although private observance of religious rituals could continue, religion and religious organization were excluded from public life.

In addition to the abolition of the caliphate, new laws mandated the abolition of the office of [Şeyhülislam](/source/%C5%9Eeyh%C3%BClislam) and the religious [hierarchy](/source/hierarchy), the closing and confiscation of [Sufi](/source/Sufism) lodges, meeting places, and [monasteries](/source/Monastery) and the outlawing of their rituals and meetings, the establishment of government control over [vakıfs](/source/Waqf) which had been inalienable under [Sharia](/source/Sharia), the replacement of sharia with adapted European legal codes; the closing of religious schools; the abandonment of the [Islamic calendar](/source/Islamic_calendar) in favor of the [Gregorian calendar](/source/Gregorian_calendar) used in the West, and restrictions on public attire that had religious associations, with the [fez](/source/Fez_(clothing)) outlawed for men and the [veil](/source/veil) discouraged for women.

Atatürk and his colleagues also attempted to "turkify" Islam through official encouragement of practices such as the usage of [Turkish](/source/Turkish_language) rather than [Arabic](/source/Arabic) at devotions, substituting the Turkish word [Tanrı](/source/Tanr%C4%B1) for the Arabic word [Allah](/source/Allah), and incorporating Turkish into daily calls to prayer. These changes in devotional practices caused widespread criticism among Muslims, which led to a return to the Arabic version of the call to prayer in 1950, after the opposition party [DP](/source/Democratic_Party_(Turkey%2C_historical)) won the elections. Of longer-lasting effect were the regime's measures of prohibiting religious education, restricting the building of new [mosque](/source/mosque)s, and transferring existing mosques to secular purposes - most notably the [Hagia Sophia](/source/Hagia_Sophia) (Justinian's sixth-century Christian [basilica](/source/basilica), which had been converted into a mosque by [Mehmet II](/source/Mehmet_II)), which was turned into a museum in 1935. Muftis and [imam](/source/imam)s were appointed by the government, and religious instruction was taken over by the [Ministry of National Education](/source/Ministry_of_National_Education_(Turkey)). As a result of these policies, the Turkish Republic was judged negatively by some sections of the Muslim world.

The common expectation was that these policies of the 1920s and 1930s would diminish the role of religion in public, which, however, did not occur. As early as 1925, religious grievances were one of the principal causes of the [Şeyh Sait rebellion](/source/Sheikh_Said_Rebellion), an uprising in southeastern Turkey that may have claimed as many as 30,000 lives before being suppressed.

Although Turkey was secularized at a legal level, religion remained a strong force. After 1950, some political leaders espoused support for programs and policies that appealed to the religiously inclined in an attempt to benefit from a lot of the population's attachment to religion. Such efforts were opposed by most of the state, who believed that secularism was an essential principle of [Kemalist Ideology](/source/Kemalist_Ideology). This gradually led to a polarization of the entire country, which became especially evident in the 1980s, as a new generation of religiously motivated local leaders emerged to challenge the dominance of the secularized political elite.

Following the loosening of authoritarian political control in 1946, a large number of people began to openly call for a return to traditional religious practices.

A more direct manifestation of the growing reaction against secularism was the revival of the Sufi brotherhoods. Not only did suppressed Sufi orders such as the [Kadiri](/source/Qadiriyya), [Mevlevi](/source/Mevlevi), [Nakşibendi](/source/Nak%C5%9Fibendi), [Khālidiyyā](/source/Khalidiyya) and [Al-Ṭarīqah al-Tijāniyyah](/source/Al-%E1%B9%ACar%C4%ABqah_al-Tij%C4%81niyyah) reemerge, but new movements were formed, including the [Nur](/source/Nursi) [Cemaat](/source/Nur_Movement)i, [Gülen movement](/source/G%C3%BClen_movement), [Sülaymānīyyā](/source/S%C3%BCleymanc%C4%B1), [Community of İskenderpaşa](/source/Community_of_%C4%B0skenderpa%C5%9Fa) and [İsmailağa](/source/%C4%B0smaila%C4%9Fa). The Tijāni became especially militant in confronting the state, damaging monuments to Atatürk to symbolize their opposition to his policy of secularization. This was, however, an isolated incident and only involved one particular [Sheikh](/source/Sheikh) of the order. Throughout the 1950s, there were numerous trials of Ticani and other Sufi leaders for anti-state activities.

Simultaneously, some movements, notably the Süleymancı and Nurcular, cooperated with those politicians perceived as supportive of pro-Islamic policies. The Nurcular eventually advocated support for Turkey's [multi-party political system](/source/Multi-party_system), and one of its offshoots, the [Gülen movement](/source/G%C3%BClen_movement), had supported the [True Path Party](/source/True_Path_Party) while the [Işıkçılar](/source/H%C3%BCseyin_Hilmi_I%C5%9F%C4%B1k) and [Enver Ören](/source/Enver_%C3%96ren) had openly supported the [Motherland Party](/source/Motherland_Party_(Turkey)) since the mid-1980s.

The demand for restoration of religious education in public schools began in the late 1940s. The government initially responded by authorizing religious instruction in state schools for those students whose parents requested it. Under the rule of the [Democrat Party](/source/Democrat_Party_(Turkey%2C_1946%E2%80%931961)) during the 1950s, religious education was made compulsory in secondary schools unless parents made a specific request to have their children excused. Religious education was made compulsory for all primary and secondary school children in 1982.
[[File:ANKARA_KOCATEPE_CAMİİ.jpg|thumb|[Kocatepe Mosque](/source/Kocatepe_Mosque), [Ankara](/source/Ankara).]]
The reintroduction of religion into the school curriculum raised the question of religious higher education. The seculars believed that Islam could be "reformed" if future leaders were trained in state-controlled seminaries. To further this goal, the government in 1949 established a faculty of divinity at [Ankara University](/source/Ankara_University) to train teachers of Islam and imams. In 1951 [the Democrat Party](/source/Democrat_Party_(Turkey%2C_historical)) government set up special secondary schools ([İmam Hatip school](/source/%C4%B0mam_Hatip_school)s) for the training of imams and preachers. The number of these schools expanded rapidly to over 250 during the 1970s, when the pro-Islam [National Salvation Party](/source/National_Salvation_Party) participated in coalition governments. Following the [1980 coup](/source/1980_Turkish_coup_d'%C3%A9tat), the military, although secular in orientation, viewed religion as an effective means to counter [socialist](/source/Socialism) ideas and thus authorized the construction of 90 more İmam Hatip high schools.

During the 1970s and 1980s, Islam experienced [political rehabilitation](/source/political_rehabilitation) due to center-right secular leaders perceiving religion as a potential bulwark in their ideological struggle with center-left secular leaders. A small advocacy group that became extremely influential was the [Intellectuals' Hearth](/source/Intellectuals'_Hearth) ({{langx|tr|Aydınlar Ocağı}}), an organization that holds the beliefs that true Turkish culture is a synthesis of the Turks' pre-Islamic traditions and Islam. According to the Hearth, Islam not only constitutes an essential aspect of Turkish culture, but is a force that can be regulated by the state to help socialize the people to be obedient citizens acquiescent to the overall secular order. After the 1980 coup, many of the Hearth's proposals for restructuring schools, colleges, and state broadcasting were adopted. The result was a purge from these state institutions of more than 2,000 intellectuals perceived as espousing leftist ideas incompatible with the Hearth's vision of Turkey's national culture.
[[File:Blue_Mosque_2.jpg|thumb|Interior of the [Sultan Ahmed Mosque](/source/Sultan_Ahmed_Mosque), Istanbul, built in 1616.]]
The state's more tolerant attitude toward Islam encouraged the proliferation of private religious activities, including the construction of new mosques and [Qur'an](/source/Qur'an) schools in the cities, the establishment of Islamic centers for research on and conferences about Islam and its role in Turkey, and the establishment of religiously oriented professional and women's journals. The printing of newspapers, the publication of religious books, and the growth of innumerable religious projects ranging from health centers, child-care facilities, and youth hostels to financial institutions and consumer cooperatives flourished. When the government legalized private broadcasting after 1990, several Islamic radio stations were organized. In the summer of 1994, the first Islamic television station, [Kanal 7](/source/Kanal_7), began broadcasting, first in [Istanbul](/source/Istanbul) and then in [Ankara](/source/Ankara).

Although the [tarikah](/source/Tariqa) have played a seminal role in Turkey's religious revival and in the mid-1990s still published, several of the country's most widely circulated religious journals and newspapers, a new phenomenon, ''[İslamcı Aydın](/source/%C4%B0slamc%C4%B1_Ayd%C4%B1n)'' (the Islamist intellectual), unaffiliated with the traditional Sufi orders, emerged during the 1980s. Prolific and popular writers such as [Ali Bulaç](/source/Ali_Bula%C3%A7), [Rasim Özdenören](/source/Rasim_%C3%96zden%C3%B6ren), and [İsmet Özel](/source/%C4%B0smet_%C3%96zel) drew upon their knowledge of Western philosophy, [Marxist](/source/Marxist) sociology, and radical Islamist political theory to advocate for a modern Islamic perspective that does not hesitate to criticize societal issues while simultaneously remaining faithful to the ethical values and spiritual dimensions of religion. [Islamist](/source/Islamism) intellectuals are harshly critical of Turkey's secular intellectuals, whom they fault for trying to do in Turkey what Western intellectuals did in Europe: substitute worldly [materialism](/source/materialism), in its [capitalist](/source/Capitalism) or socialist version, for religious values.

By 1994, slogans promising that a return to Islam would cure economic ills and solve the problems of bureaucratic inefficiencies had enough general appeal to enable avowed religious candidates to win mayoral elections in [Istanbul](/source/Istanbul) and [Ankara](/source/Ankara).

On 15 July 2016, a [coup d'état](/source/coup_d'%C3%A9tat) was attempted in Turkey against state institutions by a faction within the [Turkish Armed Forces](/source/Turkish_Armed_Forces) with connections to the Gülen movement, citing an erosion in secularism.

Although intellectual debates on the role of Islam attracted widespread interest, they did not provoke the kind of controversy that erupted over the issue of appropriate attire for Muslim women. During the early 1980s, female college students who were determined to demonstrate their commitment to Islam began to cover their heads and necks with scarves and wear long, shape-concealing overcoats. The appearance of these women in the [citadel](/source/citadel)s of Turkish secularism shocked those men and women who tended to perceive such attire as a symbol of the Islamic traditionalism they rejected. Militant secularists persuaded the Higher Education Council to issue a regulation in 1987 forbidding female university students to cover their heads in class. Protests by thousands of religious students and some university professors forced several universities to waive enforcement of the dress code. The issue continued to be seriously divisive in the mid-1990s. Throughout the first half of the 1990s, highly educated, articulate but religiously pious women have appeared in public dressed in Islamic attire that conceals all but their faces and hands. Other women, especially in [Ankara](/source/Ankara), [Istanbul](/source/Istanbul), and [İzmir](/source/%C4%B0zmir), have demonstrated against such attire by wearing revealing fashions and Atatürk badges. The issue is discussed and debated in almost every type of forum – artistic, commercial, cultural, economic, political, and religious. For many citizens of Turkey, women's dress has become the issue that defines whether a Muslim is secularist or religious. In 2010, the Turkish Higher Educational council (YÖK) lifted the ban on headscarves at the universities. Since the start of his presidency, President Recep Tayyip Erdogan has drastically increased the amount of religious high schools across Turkey to support his plan on bringing up a more pious generation. However, this push on piousness in school children seems to have had an adverse effect, for there is anecdotal evidence of a notable number of Turkish students from religious high schools admitting their loss of faith in Islamic beliefs, which has caused substantial amount of discussion among politicians and religious clerics.<ref>{{Cite news|url=https://www.bbc.com/news/world-europe-43981745|title=Losing their religion: The young Turks rejecting Islam|last=Girit|first=Selin|date=2018-05-10|access-date=2019-11-10|language=en-GB|archive-date=3 April 2019|archive-url=https://web.archive.org/web/20190403210646/https://www.bbc.com/news/world-europe-43981745|url-status=live}}</ref>

[https://www.independent.co.uk/news/world/europe/turkey-hijab-headscarf-police-officers-uniform-approved-muslim-women-a7213861.html More recently in 2016, Turkey approved hijab as the part of the official police uniform]. For the first time, female officers will be able to cover their heads with a headscarf under their police caps. This act was pushed by President Recep Tayyip Erdogan's Islamist-rooted Justice and Development Party (AKP) that have been pushing for relaxed restrictions on the hijab.

Complicating the making of an accurate estimate of the population of the different Shi'i sects or even distinguishing between them and  is that in the [Turkish language](/source/Turkish_language) the term ''[Aleviler](/source/Aleviler)'' rather than "[Shi'a](/source/Shi'a)" has been frequently used to refer to [Shi'a](/source/Shi'a) in general -- Alevi being the dominant [Shia](/source/Shia_Islam) sect in the country. 
Other difficulties are that censuses conducted by the Turkish government do not ask about religious denominations;  the secular tendencies of the Alevi population and oppression by Sunni Islamists, which causes most Alevis to hide their religious identity. Based on the few reliable surveys that have been conducted, ~10% is thought to be an adequate estimate.<ref name="interaktif.konda.com.tr"/><ref name=Seskir-2020>{{Cite web |last=Seskir |first=Zeki |date=2020-06-24 |title="Türkiye'de 40 milyon Kürt 25 milyon Alevi olması" ya da "Türkiye Türklerindir" |url=https://medium.com/duzensiz/t%C3%BCrkiyede-40-milyon-k%C3%BCrt-25-milyon-alevi-olmas%C4%B1-ya-da-t%C3%BCrkiye-t%C3%BCrklerindir-44d32e90e06e  |website=Medium |language=en }}</ref><ref name="pewresearch.org">{{Cite web |date=2009-10-07 |title=Mapping the Global Muslim Population |url=https://www.pewresearch.org/religion/2009/10/07/mapping-the-global-muslim-population/ |access-date=2022-08-14 |website=Pew Research Center's Religion & Public Life Project |language=en-US |archive-date=14 June 2022 |archive-url=https://web.archive.org/web/20220614051531/https://www.pewresearch.org/religion/2009/10/07/mapping-the-global-muslim-population/ |url-status=live }}</ref>

===Sufism===

{{Sufism|collapsed=1}}
[[File:Whirlingdervishes.JPG|thumb|Turkish Sufi [whirling dervishes](/source/whirling_dervishes).]]
Folk Islam in Turkey has derived many of its popular practices from [Sufism](/source/Sufism) which has good presence in Turkey and [Egypt](/source/Egypt). Particular Sufi [shaikh](/source/Sheikh)s – and occasionally other individuals reputed to be pious – were regarded after death as saints having special powers. Veneration of saints (both male and female) and pilgrimages to their shrines and graves represent an important aspect of popular Islam in the country. Folk Islam has continued to embrace such practices although the veneration of saints officially has been discouraged since the 1930s. Plaques posted in various sanctuaries forbid the lighting of candles, the offering of votive objects, and related devotional activities in these places. Modern day Sufi shaykhs with large adherents in Turkey include Shaykh Mehmet Efendi{{who|date=July 2013}} (residing in Istanbul) and [Mawlana Sheikh Nazim Al-Haqqani](/source/Mawlana_Sheikh_Nazim_Al-Haqqani) who resided in [Lefka](/source/Lefka), North Cyprus, until his death in May, 2014.
