Religion in Europe has been a major influence on today's society, art, culture, philosophy and law. The largest religion in Europe is Christianity, but irreligion and practical secularization are strong. Two countries in Southeastern Europe have Muslim majorities. Ancient European religions included veneration for deities such as Zeus. Modern revival movements of these religions include Heathenism, Rodnovery, Romuva, Druidry, Wicca, and others. Smaller religions include Indian religions, Judaism, and some East Asian religions, which are found in their largest groups in Britain, France, and Kalmykia.
Little is known about the prehistoric religion of Neolithic Europe. Bronze and Iron Age religion in Europe as elsewhere was predominantly polytheistic (Ancient Greek religion, Ancient Roman religion, Basque mythology, Finnish paganism, Celtic polytheism, Germanic paganism, etc.).
The Roman Empire officially adopted Christianity in AD 380. During the Early Middle Ages, most of Europe underwent Christianization, a process essentially complete with the Christianization of Scandinavia in the High Middle Ages. The notion of "Europe" and the "Western World" has been intimately connected with the concept of "Christianity and Christendom"; many even attribute Christianity for being the link that created a unified European identity, especially since Christianity in the Middle East was marginalized by the rise of Islam from the 8th century, a constellation that led to the Crusades, which although unsuccessful militarily were an important step in the emergence of a religious identity of Europe. At all times, traditions of folk religion existed largely independent from official denomination or dogmatic theology.
The Great Schism of the 11th century and Reformation of the 16th century were to tear apart Christendom into hostile factions, and following the Age of Enlightenment of the 18th century, atheism and agnosticism have spread across Europe. 19th-century Orientalism contributed to a certain popularity of Buddhism, and the 20th century brought increasing syncretism, New Age, and various new religious movements divorcing spirituality from inherited traditions for many Europeans. The latest history brought increased secularisation, and religious pluralism.
European countries have experienced a decline in church membership and church attendance. A relevant example of the ongoing trend is Sweden where the church 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 and to 59.3% by 2017. Moreover, in the 2005 Eurobarometer survey 23% of the Swedish population said that they don't believe there is any sort of spirit, God or life force and in the 2010 Eurobarometer survey 34% said the same.
During 2008-2009, a Gallup survey asked in several countries the question "Is religion important in your daily life?" The table and map below shows percentage of people who answered "Yes" to the question.
The 2010 Eurobarometer survey found that, on average, 51% of the citizens of EU 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 in Denmark, Belgium, France, Germany, the Netherlands, and Sweden has been noted, despite a concurrent increase in some countries 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 the British Humanist Association. 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.
The following is a list of European countries ranked by religiosity, based on the rate of belief, according to the Eurobarometer survey 2010. 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 the World Values Survey, 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%.

The first newspaper reference to the religious movement began with coverage of the Báb, whom Bahá'ís consider the founder of a precursor religion, occurred in The Times on 1 November 1845, only a little over a year after the Báb first started his mission. British, Russian, and other diplomats, businessmen, scholars, and world travelers also took note of the precursor Bábí religion most notably in 1865 by Frenchman Arthur de Gobineau who wrote the first and most influential account. In April 1890 Edward G. Browne of Cambridge University met Bahá'u'lláh and left the only detailed description by a Westerner.
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 a three-year journey to including Europe and North America and then wrote a series of letters that were compiled together in the book titled Tablets of the Divine Plan which included mention of the need to spread the religion in Europe following the war.
A 1925 list of "leading local Bahá'í Centres" of Europe listed organized communities of many countries - the largest being in Germany. However the religion was soon banned in a couple countries: in 1937 Heinrich Himmler disbanded the Bahá'í Faith's institutions in Germany because of its 'international and pacifist tendencies' and in Russia in 1938 "monstrous accusations" against Bahá'ís and a Soviet government policy of oppression of religion resulted in Bahá'í communities in 38 cities across Soviet territories ceasing to exist. However the religion recovered in both countries. The religion has generally spread such that in recent years the Association of Religion Data Archives estimated the Bahá'ís in European countries to number in hundreds to tens of thousands.
The majority of Europeans describe themselves as Christians, divided into a large number of denominations.Christian denominations are usually classed in three categories: Catholicism, Orthodoxy and Protestantism (a diverse group including Lutheranism, Calvinism and Anglicanism as well as numerous minor denominations, including Baptists, Methodism, Evangelicalism, Pentecostalism, etc.).
European culture, throughout most of its recent history, has been heavily influenced by Christian belief and has been nearly equivalent to Christian culture. The Christian culture was one of the more dominant forces to influence western civilization, concerning the course of philosophy, art, music, science, social structure and architecture. The Civilizing influence of Christianity includes social welfare, founding hospitals,economics (as the Protestant work ethic),politicsarchitecture,literature and family life.
Christianity is still the largest religion in Europe. According to a 2010 study by the Pew Research Center, 76.2% of the European population identified themselves as Christians. According to a 2012 survey about Religiosity in the European Union in 2012 by Eurobarometer, Christianity was the largest religion in the European Union (account 72% of EU population), Catholics were the largest Christian group in EU, and accounted for 48% of the EU population, while Protestants made up 12%, Eastern Orthodox made up 8%, and other Christians 4%.

There are numerous minor Protestant movements, including various Evangelical congregations.
Islam came to parts of European islands and coasts on the Mediterranean during the 8th-century Muslim conquests. In the Iberian Peninsula and parts of southern France, various Muslim states existed before the Reconquista; Islam spread in southern Italy briefly through the Emirate of Sicily and Emirate of Bari. During the Ottoman expansion, Islam was spread from into the Balkans and even part of central Europe. Muslims have also been historically present in Ukraine (Crimea and vicinity, with the Crimean Tatars), as well as modern-day Russia, beginning with Volga Bulgaria in the 10th century and the conversion of the Golden Horde to Islam. In recent years, Muslims have migrated to Europe as residents and temporary workers.
According to the Pew Forum, the total number of Muslims in Europe in 2010 was about 44 million (6%). While the total number of Muslims in the European Union in 2007 was about 16 million (3.2%).
Muslims make up 99% of the population in Northern Cyprus, 96% in Kosovo, 56% in Albania, 51% in Bosnia and Herzegovina, 39.3% in Macedonia, 20% in Montenegro, between 10 and 15% in Russia, 7 -9% in France, 8% in Bulgaria, 6% in the Netherlands, 5% in Denmark, United Kingdom and Germany., just over 4% in Switzerland and Austria, between 3 and 4% in Greece
The Jews were dispersed within the Roman Empire from the 2nd century. At one time Judaism was practiced widely throughout the European continent; throughout the Middle Ages, Jews were accused of ritual murder and faced pogroms and legal discrimination. The Holocaust perpetrated by Nazi Germany decimated Jewish 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). Other European countries with notable Jewish populations include the United Kingdom (291,000 Jews),Germany (119,000), and Russia (194,000) which is home to Eastern Europe's largest Jewish community.
During the Enlightenment, Deism became influential especially in France, Germany, the Netherlands, and the United Kingdom. Biblical concepts were challenged by concepts such as a heliocentric universe and other scientific challenges to the Bible. Notable early deists include Voltaire and Kant .
The trend towards secularism during the 20th and 21st centuries has a number of reasons, depending on the individual country:
The trend towards secularism has been less pronounced in the traditionally Catholic countries of Mediterranean Europe. Greece as the only traditionally Eastern Orthodox country in Europe which has not been part of the communist Eastern Bloc also retains a very high religiosity, with in excess of 95% of Greeks adhering to the Greek Orthodox Church.
According to a Pew Research Center Survey in 2012 the Religiously Unaffiliated (Atheists and Agnostics) make up about 18.2% of the European population in 2010. According to the same Survey the Religiously Unaffiliated make up the majority of the population in only two European countries: Czech Republic (76%) and Estonia (60%). A newer study (released 2015) found that in the Netherlands there is also an irreligious majority of 68%.
During the late 20th and early 21st centuries, atheism and agnosticism have increased, with falling church attendance and membership in various European countries. The 2010 Eurobarometer survey found that on total average, of the EU28 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". Across the EU, belief was higher among women, increased with age, those with strict upbringing, those with the lowest levels of formal education and those leaning towards right-wing politics.:10-11 Results were varied widely between different countries.
According to a survey measuring religious identification in the European Union in 2012 by Eurobarometer, 7% of EU citizens identify themselves as atheists. As of 2012, the top eight European countries with people who viewed themselves as "atheists" were the Czech Republic (20%), France (16%), Slovenia (16%), Estonia (15%), Sweden (13%), Spain (10%), Germany (9%) and Denmark (9%).
In the United Kingdom Census 2001, 300 people registered as Heathen in England and Wales. However, many Heathens followed the advice of the Pagan Federation (PF) and simply described themselves as "Pagan", while other Heathens did not specify their religious beliefs. In the 2011 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.
Ásatrúarfélagið (Esetroth Fellowship) was recognized as an official religion by the Icelandic government in 1973. For its first 20 years it was led by farmer and poet Sveinbjörn Beinteinsson. By 2003, it had 777 members, and by 2014, it had 2,382 members, corresponding to 0.8% of Iceland's population. In Iceland, Germanic religion has an impact larger than the number of its adherents.
In Sweden, the Swedish Forn Sed Assembly (Forn Sed, or the archaic Forn Siðr, means "Old Custom") was formed in 1994 and is since 2007 recognized as a religious organization by the Swedish government.
