Religion has been a major influence on the societies,cultures,traditions,philosophies,artistic expressions andlaws within present-dayEurope. The largestreligion in Europe isChristianity.^[1] However,irreligion and practicalsecularisation are also prominent in some countries.^[2][3] In Southeastern Europe, three countries (Bosnia and Herzegovina,Kosovo andAlbania) haveMuslim majorities, with Christianity being the second-largest religion in those countries.

Little is known about theprehistoric religion ofNeolithic Europe. Bronze and Iron Agereligion in Europe as elsewhere was predominantlypolytheistic and includedAncient Greek religion,Ancient Roman religion,Slavic paganism,Finnish paganism,Celtic polytheism andGermanic paganism. Modern revival movements of these religions, and religions influenced by them, includeHeathenism,Rodnovery,Romuva,Druidry,Wicca, andHetanism.

TheRoman Empire officially adopted Christianity in AD 380. Most of Europe underwentChristianisation during theEarly Middle Ages, with the process being essentially complete with theChristianisation of Lithuania in theHigh Middle Ages, with the exception ofAl-Andalus. The notion of "Europe" and the "Western World" has been intimately connected with the concept of "Christendom", and many even consider Christianity as the unifying belief that created aEuropean identity,^[4] especially since Christianity in the Middle East was marginalized by the rise ofIslam from the 8th century. This confrontation led to theCrusades, which ultimately failed militarily, but were an important step in the emergence of a European identity based on religion. Despite this, traditions offolk religion continued at all times, largely independent from institutional religion or dogmatic theology.

TheGreat Schism of the 11th century andReformation of the 16th century tore apart Christendom into hostile factions, and following theAge of Enlightenment of the 18th century,atheism andagnosticism have spread across Europe. Nineteenth-centuryOrientalism contributed to a certain popularity ofHinduism andBuddhism, and the 20th century brought increasingsyncretism,New Age, and variousnew religious movements divorcing spirituality from inherited traditions for many Europeans. Recent times have seen increased secularisation andreligious pluralism.^[5] Smaller religions includeIndian religions,Judaism, and someEast Asian religions, which are found in their largest groups inBritain,France, andKalmykia.

Some European countries have experienced a decline in church membership and church attendance.^[6][7] A relevant example of this trend isSweden where theChurch of Sweden, previously the state-church until 2000, claimed to have 82.9% of the Swedish population as its flock in 2000. Surveys showed this had dropped to 72.9% by 2008^[8] and to 56.4% by 2019.^[9] Moreover, in the 2005 Eurobarometer survey 23%^[10] of the Swedish population said that they do not believe there is any sort of spirit, God or life force and in the 2010 Eurobarometer survey 34%^[2] said the same.

The 2010 Eurobarometer survey^[2] found that, on average, 51% of the citizens of theEU member states state that they "believe there is a God", 26% "believe there is some sort of spirit or life force" while 20% "don't believe there is any sort of spirit, God or life force". 3% declined to answer.According to a recent study (Dogan, Mattei, Religious Beliefs in Europe: Factors of Accelerated Decline), 47% of French people declared themselves as agnostics in 2003. This situation is often called "Post-Christian Europe". A decrease in religiousness and church attendance inDenmark,Belgium,France,Germany,Netherlands, andSweden has been noted, despite a concurrent increase in some countries like Greece (2% in 1 year). The Eurobarometer survey must be taken with caution, however, as there are discrepancies between it and national census results. For example, in the United Kingdom, the 2001 census revealed over 70% of the population regarded themselves as "Christian" with only 15% professing to have "no religion", though the wording of the question has been criticized as "leading" by theBritish Humanist Association.^[15] Romania, one of the most religious countries in Europe, witnessed a threefold increase in the number of atheists between 2002 and 2011, as revealed by the most recent national census.^[16]

The following is a list of European countries ranked by religiosity, based on the rate of belief, according to the Eurobarometer survey 2010.^[2] The 2010 Eurobarometer survey asked whether the person "believes there is a God", "believes there is some sort of spirit or life force", or "doesn't believe there is any sort of spirit, God or life force".

The decrease in theism is illustrated in the 1981 and 1999 according to theWorld Values Survey,^[17] both for traditionally strongly theist countries (Spain: 86.8%:81.1%; Ireland 94.8%:93.7%) and for traditionally secular countries (Sweden: 51.9%:46.6%; France 61.8%:56.1%; Netherlands 65.3%:58.0%). Some countries nevertheless show increase of theism over the period, Italy 84.1%:87.8%, Denmark 57.8%:62.1%. For a comprehensive study on Europe, seeMattei Dogan's "Religious Beliefs in Europe: Factors of Accelerated Decline" inResearch in the Social Scientific Study of Religion.

According to the 2019Eurobarometer survey about Religiosity in theEuropean UnionChristianity is the largest religion in the European Union accounting 64% of the EU population,^[18] down from 72% in 2012.^[20]Catholics are the largestChristian group in EU, accounting for 41% of EU population, whileEastern Orthodox make up 10%, andProtestants make up 9%, and other Christians account for 4% of the EU population.Non believer/Agnostic account 17%,Atheist 10%, andMuslim 2% of the EU population. 3% refuse to answer or didn't know.^[18]

The first reference to the religious movement in a European newspaper began with coverage of theBáb, whom Bahá'ís consider the forerunner of theBahá'í Faith, which occurred inThe Times on 1 November 1845, only a little over a year after the Báb first started his mission.^[25] British, Russian, and other diplomats, businessmen, scholars, and world travelers also took note of the precursorBábí religion^[26] most notably in 1865 by FrenchmanArthur de Gobineau who wrote the first and most influential account. In April 1890Edward G. Browne ofCambridge University metBahá'u'lláh, the prophet-founder of the Bahá'í Faith, and left the only detailed description by a Westerner.^[27]

Starting in the 1890s Europeans began to convert to the religion. In 1910 Bahá'u'lláh's son and appointed successor,'Abdu'l-Bahá embarked on athree-year journey to including Europe and North America^[28] and then wrote a series of letters that were compiled together in the book titledTablets of the Divine Plan which included mention of the need to spread the religion in Europe following the war.^[29]

A 1925 list of "leading local Bahá'í Centres" of Europe listed organized communities of many countries – the largest being in Germany.^[30] However the religion was soon banned in a couple of countries: in 1937Heinrich Himmler disbanded the Bahá'í Faith's institutions in Germany because of its 'international and pacifist tendencies'^[31] and in Russia in 1938 "monstrous accusations" against Bahá'ís and aSoviet government policy of oppression of religion resulted in Bahá'í communities in 38 cities across Soviet territories ceasing to exist.^[32] However the religion recovered in both countries. The religion has generally spread such that in recent years theAssociation of Religion Data Archives estimated the Bahá'ís in European countries to number in hundreds to tens of thousands.^[33]

The majority of Europeans describe themselves asChristians, divided into a large number of denominations.^[1]Christian denominations are usually classed in three categories:Catholicism (consider only two groups, theRoman-Latin Catholic and theEastern Greek and Armenian Catholics),Orthodoxy (consider only two groups, theEastern Byzantine Orthodox and theArmenian Apostolic which is within theOriental Orthodox Church) andProtestantism (a diverse group includingLutheranism,Calvinism andAnglicanism as well as numerous minor denominations, includingBaptists,Methodism,Evangelicalism,Pentecostalism, etc.).

Christianity, more specifically theCatholic Church, which played an important part in the shaping ofWestern civilization since at least the 4th century.^[35][36] Historically, Europe has been the center and "cradle ofChristian civilization".^{[37][38][39][40]}

European culture, throughout most of its recent history, has been heavily influenced by Christian belief and has been nearly equivalent toChristian culture.^[41] The Christian culture was one of the more dominant forces to influence Western civilization, concerning the course ofphilosophy,art,music,science,social structure andarchitecture.^[41][42] The civilizing influence of Christianity includessocial welfare,^[43] foundinghospitals,^[44]economics (as theProtestant work ethic),^[45][46]politics,^[47]architecture,^[48]literature^[49] andfamily life.^[50]

Christianity is still the largest religion inEurope.^[51] According to a survey about Religiosity in the European Union in 2019 byEurobarometer, Christianity was the largest religion in theEuropean Union accounting 64% of EU population,^[18] down from 72% in 2012.^[20]Catholics were the largest Christian group in EU, and accounted for 41% of the EU population, whileEastern Orthodox made up 10%,Protestants made up 9%, and other Christians 4%.^[18] According to a 2010 study by thePew Research Center, 76.2% of the European population identified themselves as Christians,^[52] constitute in absolute terms theworld's largest Christian population.^[53]

According to Scholars, in 2017, Europe's population was 77.8% Christian (up from 74.9% 1970),^[54][55] these changes were largely result of thecollapse of Communism andswitching to Christianity in the formerSoviet Union andEastern Bloc countries.^[54]

Islam came to parts of European islands and coasts on theMediterranean Sea during the 8th-centuryMuslim conquests. In theIberian Peninsula and parts of southernFrance, various Muslim states existed before theReconquista;Islam spread in southern Italy briefly through theEmirate of Sicily andEmirate of Bari. During theOttoman expansion, Islam was spread from into theBalkans and even part ofCentral Europe. Muslims have also been historically present inUkraine (Crimea and vicinity, with theCrimean Tatars), as well as modern-dayRussia, beginning withVolga Bulgaria in the 10th century and the conversion of theGolden Horde to Islam. In recent years,^[when?] Muslims havemigrated to Europe as residents and temporary workers.

According to thePew Forum, the total number ofMuslims inEurope in 2010 was about 44 million (6%).^[58] While the total number of Muslims in theEuropean Union in 2007 was about 16 million (3.2%).^[59] Data from the 2000s for the rates of growth of Islam in Europe showed that the growing number of Muslims was due primarily to immigration and higherbirth rates.^[60]

Muslims make up 99% of the population inTurkey,^[61]Northern Cyprus,^[62][63] 96% inKosovo,^[64] 56% inAlbania,^[65][66] 51% inBosnia and Herzegovina,^[67] 32.17% inNorth Macedonia,^[68][69] 20% inMontenegro,^[70] between 10 and 15% inRussia,^[71] 7–9% inFrance,^[72][73][74] 8% inBulgaria,^[75] 6% in theNetherlands, 5% inDenmark,United Kingdom andGermany,^[76][77][78] just over 4% inSwitzerland andAustria, and between 3 and 4% inGreece.

A survey conducted by the Pew Research Center in 2016 found that Muslims make up 4.9% of all of Europe's population.^[79] According to a same studyconversion does not add significantly to the growth of the Muslim population in Europe, with roughly 160,000 more people leaving Islam than converting into Islam between 2010 and 2016.^[79]

The Jews weredispersed within the Roman Empire from the 2nd century.^[80] At one timeJudaism was practiced widely throughout the European continent;throughout the Middle Ages, Jews wereaccused of ritual murder and facedpogroms and legal discrimination.The Holocaust perpetrated byNazi Germany decimated theJewish population, and today,France is home to the largest Jewish community in Europe with 1% of the total population (between 483,000 and 500,000 Jews).^[81][82] Other European countries with notable Jewish populations include theUnited Kingdom (291,000 Jews),^[82]Germany (119,000), andRussia (194,000) which is home to Eastern Europe's largest Jewish community.^[82] The Jewish population of Europe in 2010 was estimated to be approximately 1.4 million (0.2% of European population) or 10% of the world's Jewish population.^[83]

During theEnlightenment, Deism became influential especially in France, Germany, the Netherlands, and the United Kingdom. Interpretations of the Bible then common were challenged by concepts such as a heliocentric universe and other scientific concepts posited to be challenges to the Bible.^[84] Notable early deists includeVoltaire,Kant, andMendeleev.^[85]

The trend towards secularism during the 20th and 21st centuries has a number of reasons, depending on the individual country:

• France has been traditionallylaicist since the French Revolution. Today the country is 25%^[86] to 32%^[87]irreligious. The remaining population is made up evenly of both Christians and people who believe in a god or some form of spiritual life force, but are not involved in organized religion.^[88] French society is still secular overall.
• Some parts of Eastern Europe were secularized as a matter of state doctrine undercommunist rule in the countries of the formerEastern Bloc.Albania was an officially (and constitutionally binding) atheist state from 1967 to 1991.^[89] The countries where the most people reported no religious belief were France (33%), the Czech Republic (30%), Belgium (27%), Netherlands (27%), Estonia (26%), Germany (25%), Sweden (23%) and Luxembourg (22%).^[90] The region ofEastern Germany, which was also under communist rule, is by far the least religious region in Europe.^[91][92] Other post-communist countries, however, have seen the opposite effect, with religion being very important in countries such as Romania, Lithuania and Poland.

The trend towards secularism has been less pronounced in the traditionallyCatholic countries of Mediterranean Europe.Greece, traditionally known for the strong presence of the Greek Orthodox Church, has seen a gradual increase in the proportion of people identifying as atheist, agnostic, or non-religious. While findings since 1981 indicated strong religious sentiment, with around 80% of Greeks believing in God, a closer look reveals a partial retreat asIrreligion in Greece grows: in 2024, 27% of Greeks reported being indifferent to religion, up from 18% in 2018.^[93] According to a nationwide survey by Metron Analysis forTo Vima in December 2024, 66% of Greeks declared that they have a religion, but only 15% reported attending church regularly.^[94] Estimates from other sources suggest that roughly 4–15% of the population explicitly identify as atheist.^[95]

According to aPew Research Center Survey in 2012 thereligiously unaffiliated (atheists andagnostics) make up about 18.2% of theEuropean population in 2010.^[96] According to the same survey the religiously unaffiliated make up the majority of the population in only twoEuropean countries:Czech Republic (76%) andEstonia (60%).^[3] A newer study (released in 2015) found that in theNetherlands there is also an irreligious majority of 68%.^[97]

During the late 20th and early 21st centuries,atheism andagnosticism have increased, with falling church attendance and membership in various European countries.^[98] The 2010 Eurobarometer survey found that on total average, of theEU28 population, 51% "believe there is a God", 26% "believe there is some sort of spirit or life force", and 20% "don't believe there is any sort of spirit, God or life force".^[2]Across the EU, belief was higher among women, increased with age, those with a strict upbringing, those with the lowest level of formal education and those leaning towardsright-wing politics.^{[90]: 10–11} Results were varied widely between different countries.^[2]

According to a survey measuring religious identification in theEuropean Union in 2019 byEurobarometer, 10% of EU citizens identify themselves asatheists.^[18] As of May 2019^[update], the top seven European countries with the most people who viewed themselves as atheists wereCzech Republic (22%),France (21%),Sweden (16%),Estonia (15%),Slovenia (14%),Spain (12%) andNetherlands (11%).^[18] 17% of EU citizens called themselves non-believers or agnostics and this percentage was the highest in Netherlands (41%), Czech Republic (34%), Sweden (34%), United Kingdom (28%), Estonia (23%), Germany (21%) and Spain (20%).^[18]

Heathenism or Esetroth (Icelandic:Ásatrú), and the organised formOdinism, are names for the modernfolk religion of the Germanic nations.

In theUnited Kingdom Census 2001, 300 people registered as Heathen inEngland and Wales.^[99] However, many Heathens followed the advice of thePagan Federation (PF) and simply described themselves as "Pagan", while other Heathens did not specify their religious beliefs.^[99] In the2011 census, 1,958 people self-identified as Heathen in England and Wales. A further 251 described themselves as Reconstructionist and may include some people reconstructing Germanic paganism.^[100]

Ásatrúarfélagið (Esetroth Fellowship) was recognized as an official religion by theIcelandic government in 1973. For its first 20 years it was led by farmer and poetSveinbjörn Beinteinsson. By 2003, it had 777 members,^[101] and by 2014, it had 2,382 members, corresponding to 0.8% of Iceland's population.^[102] In Iceland, Germanic religion has an impact larger than the number of its adherents.^[103]

In Sweden, theSwedish Forn Sed Assembly (Forn Sed, or the archaicForn Siðr, means "Old Custom") was formed in 1994 and is since 2007 recognized as a religious organization by the Swedish government. In DenmarkForn Siðr was formed in 1999, and was officially recognized in 2003^[104] The NorwegianÅsatrufellesskapet Bifrost (Esetroth Fellowship Bifrost) was formed in 1996; as of 2011, the fellowship has some 300 members.Foreningen Forn Sed was formed in 1999, and has been recognized by the Norwegian government as a religious organization. In Spain there is theOdinist Community of Spain – Ásatrú.

TheRoman polytheism also known asReligio Romana (Roman religion) inLatin or theRoman Way to the Gods (inItalian 'Via romana agli Déi') is alive in small communities and loosely related organizations, mainly inItaly.

TheNatale di Roma, historically known asDies Romana and also referred to as Romaia, is a festival linked to thefoundation of Rome, celebrated on April 21.^[105] According tolegend,Romulus is said to have founded the city ofRome on April 21,753 BC. From this date, the Roman chronology derived its system, known by theLatin phraseAb Urbe condita, meaning"from the founding of the City", which counted the years from this presumed foundation.

The religious development ofDruidry was largely influenced byIolo Morganwg.^[106] Modern practises aim to imitate the practises of the Celtic peoples of the Iron Age.^[107]

Slavic Native Faith, commonly known as Rodnovery^[α] and sometimes as Slavic Neopaganism,^[β] emerged in 19th century but is based on much older religion from medieval era. Main countries with Slavic Neopagans are Russia (10,000^[111]–757,000^[112] Slavic Neopagans in 2012), Ukraine (5,000–10,000 Slavic Neopagans^[113]) and Poland (7,000–10,000 Slavic Neopagans).

A number of countries in Europe haveofficial religions, includingGreece (Orthodox),^[114]Liechtenstein,^[115]Malta,^[116]Monaco,^[117] theVatican City (Catholic);^[118]Armenia (Apostolic Orthodoxy);Denmark,^[119]Iceland (Lutheran);^[120][121] and theUnited Kingdom (England alone) (Anglican).^[122] InSwitzerland, somecantons are officially Catholic, others Reformed Protestant. Some Swiss villages even have their religion as well as the village name written on the signs at their entrances.

Georgia, while technically has no official church per se, has special constitutional agreement withGeorgian Orthodox Church, which enjoysde factoprivileged status. Much the same applies in Germany with the Evangelical Church and the Roman Catholic Church, and the Jewish community. InFinland, both theFinnish Orthodox Church and theLutheran Church are official. England, acountry of theUnited Kingdom (UK), hasAnglicanism as its official religion.Scotland, another country of the UK, hasPresbyterianism as itsnational church. InSweden, the national church used to beLutheranism, but it is no longer "official" since 2000.Azerbaijan,Czech Republic,Germany,France,Ireland,Italy,Luxembourg,Portugal,Serbia,Romania,Russia,Spain andTurkey are officially secular.

Buddhism is thinly spread throughout Europe, and the fastest growing religion in recent years^[123][124] with about 3 million adherents.^[125][126] InKalmykia,Tibetan Buddhism is prevalent.^[127]

Hinduism is mainly practised amongIndian immigrants. It has been growing rapidly in recent years, notably in theUnited Kingdom,France, theNetherlands andItaly.^[128] In 2010, there were an estimated 1.4 million Hindu adherents in Europe.^[129]

Jainism, small membership rolls, mainly among Indian immigrants inBelgium and theUnited Kingdom, as well as several converts from western and northern Europe.^[130][131]

Sikhism has nearly 700,000 adherents in Europe. Most of the community live inUnited Kingdom (450,000) andItaly (100,000).^[132][133] Around 10,000 Sikhs live inBelgium andFrance.^[134]Netherlands andGermany have aSikh population of 22,000.^[135][136] All other countries, such asGreece, have 5,000 or fewer Sikhs.
