Hungary’s 2022 census asked residents about their religious affiliation, and 40 percent declined to answer. Of those who responded, half identified as Roman Catholic, making Catholicism the country’s dominant faith by a wide margin. The second-largest group, at 27 percent, claimed no religion at all. These numbers sketch a country where Christian institutions built over a thousand years of history coexist with one of Europe’s fastest-growing secular populations.
This article traces religion in Hungary from King Stephen’s conversion in 1000 AD through the Reformation, the Holocaust’s destruction of Jewish communities, and the post-communist religious landscape visible in the country today.
King Stephen and the Founding of Christian Hungary
Pope Sylvester II crowned Stephen I as Hungary’s first king on December 25, 1000 AD, formally binding the Magyar kingdom to Western Christianity. Stephen’s father, Grand Prince Geza, had already begun the conversion process by inviting Benedictine monks into Magyar territory, but Stephen enforced it through legislation. He ordered every ten villages to build a church, established ten dioceses across the kingdom, and founded the Benedictine Abbey of Pannonhalma, which still operates today as a monastery and school on a hilltop in western Hungary.
Stephen’s religious policies served political purposes alongside spiritual ones. Aligning with Rome rather than Constantinople placed Hungary within the Western European diplomatic network and secured papal backing for his dynasty. The move also distinguished Hungary from its Orthodox Christian neighbors to the south and east. The Catholic Church canonized Stephen in 1083, and August 20, the feast of St. Stephen, remains Hungary’s most important national holiday.
The Arpad dynasty that followed Stephen maintained the Catholic framework for nearly five centuries. Kings founded monasteries, endowed cathedrals, and invited Dominican and Franciscan orders to establish missions across the kingdom. By the 15th century, Hungary’s church infrastructure included two archbishoprics, numerous dioceses, and hundreds of parish churches serving a population that was overwhelmingly Roman Catholic.
The Reformation and Rise of Calvinism
Martin Luther’s 95 Theses reached Hungary within years of their 1517 publication. Lutheran ideas spread first among German-speaking merchants and miners in northern Hungary’s towns. By the 1540s, a second wave of reform arrived through John Calvin’s theology, which gained converts among Magyar-speaking populations in the Great Plain and Transylvania.
The timing worked in the Reformation’s favor. The Ottoman Empire defeated Hungary’s army at the Battle of Mohacs in 1526, killing King Louis II and splitting the kingdom into three parts: Ottoman-controlled central Hungary, Habsburg-ruled western Hungary, and the semi-independent Principality of Transylvania. The fractured political situation weakened the Catholic Church’s ability to suppress Protestant movements.
Transylvania became a center of religious experimentation. The 1568 Edict of Torda, issued under Prince John Sigismund, declared Catholicism, Lutheranism, Calvinism, and Unitarianism as accepted religions, an act of official tolerance that had few parallels in 16th-century Europe. The Reformed (Calvinist) Church grew so rapidly that by the late 1500s, an estimated 80 to 90 percent of Hungary’s population had adopted some form of Protestantism.
The Catholic Counter-Reformation reversed most of these gains. Jesuit cardinal Peter Pazmany (1570-1637), Archbishop of Esztergom, led the campaign. Pazmany founded a university at Nagyszombat (now Trnava, Slovakia), published influential theological works in Hungarian, and personally converted dozens of noble families back to Catholicism. The Habsburg rulers backed these efforts with political pressure, and by the mid-1700s, Hungary had returned to a Catholic majority.
Catholicism’s Continuing Dominance
Roman Catholicism has remained Hungary’s largest denomination through every political transformation since the Counter-Reformation. The 2022 census recorded approximately 3.9 million Hungarians identifying as Roman Catholic, representing about 50 percent of those who answered the religion question.
The church’s physical presence shapes Hungary’s landscape. The Esztergom Basilica, seat of the Archbishop of Esztergom-Budapest and head of the Hungarian Catholic Church, dominates a bend in the Danube with its 100-meter dome visible from across the Slovak border. The Matthias Church on Castle Hill in Budapest, rebuilt in Gothic Revival style in the late 1800s, served as the coronation church for Hungarian kings. Smaller baroque parish churches fill town squares from Pecs to Debrecen.
Greek Catholics, who follow Eastern liturgical traditions while recognizing papal authority, form a distinct community of about 3 percent of the population. Their presence is strongest in northeastern Hungary near the Ukrainian border, centered around the city of Nyiregyhaza. The Greek Catholic cathedral in Hajdudorog serves as the seat of the Archeparchy of Hajdudorog, which oversees Greek Catholic parishes across the country.
Protestant Churches After the Counter-Reformation
The Reformed Church in Hungary (Magyar Reformatus Egyhaz) survived the Counter-Reformation and remains the country’s second-largest Christian denomination. The 2022 census counted about 1.2 million adherents, or 16 percent of respondents. The church follows Calvinist theology and maintains its strongest presence in eastern Hungary, particularly in the cities of Debrecen and Szeged.
Debrecen earned the nickname “Calvinist Rome” during the Reformation era and still hosts the Reformed Great Church (Nagytemplom), a neoclassical building that seats 3,000 worshippers. The Debrecen Reformed Theological University, one of the oldest Protestant institutions in Central Europe, trains clergy for Reformed congregations across Hungary and neighboring countries.
Lutherans account for about 3 percent of the population and concentrate in western and central Hungary, particularly among communities with historical German-speaking populations. The Evangelical Lutheran Church in Hungary operates from Budapest and maintains congregations in cities including Sopron, Gyor, and Szekesfehervar.
Both Protestant denominations experienced suppression during the communist era (1948-1989). The state nationalized church schools, restricted religious education, and placed clergy under surveillance. Church attendance dropped across all denominations during these decades, a decline that continued after 1989 as newly available consumer culture and media competed for Hungarians’ time and attention.
Jewish Heritage and the Budapest Synagogue
Jewish communities settled in Hungary as early as the Roman period, with documented presence in Pannonia before the Magyar conquest of 896 AD. By the 19th century, Budapest housed one of Europe’s largest and most culturally productive Jewish populations. Hungarian Jews contributed to the sciences, literature, music, and commerce at a level disproportionate to their numbers.
The Dohany Street Great Synagogue in Budapest, completed in 1859, stands as the largest synagogue in Europe and the second largest in the world. Designed by Viennese architect Ludwig Forster in Moorish Revival style, the building seats approximately 3,000 worshippers. Its twin onion-domed towers and ornate facade mark the edge of what became the Budapest Jewish Quarter.
The Holocaust devastated Hungary’s Jewish population. Approximately 825,000 Jews lived in Greater Hungary in 1941. Between May and July 1944, the Arrow Cross regime and German occupation forces deported roughly 437,000 Hungarian Jews to Auschwitz-Birkenau. An additional tens of thousands died in forced labor battalions, death marches, and the Budapest ghetto during the winter of 1944-1945. The tree-shaped memorial by sculptor Imre Varga in the synagogue’s courtyard bears the names of victims on its metal leaves.
Today, Hungary’s Jewish community numbers between 75,000 and 100,000 people, concentrated in Budapest. The city maintains active synagogues, Jewish schools, kosher restaurants, and cultural organizations. The annual Budapest Jewish and Israeli Cultural Festival draws performers and audiences from across Europe.
Islam, Eastern Orthodoxy, and Newer Communities
Ottoman rule (1541-1699) brought Islam to central Hungary. Turkish administrators built mosques, public baths, and minarets in cities including Buda, Pecs, and Eger. The minaret in Eger, one of the northernmost Ottoman minarets in Europe, still stands at 40 meters. The Mosque of Pasha Qasim in Pecs, now a Catholic church, preserves its original Ottoman dome and minaret base.
After the Habsburgs expelled the Ottomans, Islam’s presence in Hungary shrank to near zero. The modern Muslim population, numbering a few thousand, consists primarily of immigrants from Middle Eastern and North African countries who arrived after 1989.
Eastern Orthodox Christians in Hungary include small Serbian, Romanian, and Greek communities whose churches date to the 18th and 19th centuries. The Serbian Orthodox Cathedral in Szentendre, north of Budapest, serves as a cultural landmark in a town known for its art galleries and museums.
Newer religious movements with small but active followings include Pentecostal congregations (organized as the Faith Congregation), the Hungarian Krishna Consciousness Society, Buddhist communities, and several evangelical Christian groups. Together these account for less than 5 percent of the population.
Frequently Asked Questions
What is the main religion in Hungary?
Roman Catholicism is Hungary’s largest religion. The 2022 census recorded approximately 50 percent of respondents identifying as Roman Catholic. The second-largest group, at 27 percent, reported no religious affiliation. The Reformed (Calvinist) Church follows at 16 percent, with Lutherans and Greek Catholics each at about 3 percent.
Why is there a large Calvinist population in Hungary?
The Reformation spread rapidly through Hungary after the Ottoman defeat at Mohacs in 1526 fractured the kingdom and weakened Catholic institutional control. Calvinism took root among Magyar speakers in the Great Plain and Transylvania. The 1568 Edict of Torda formally recognized Calvinism alongside other faiths. Though the Counter-Reformation restored Catholic dominance, Calvinist communities survived and remain concentrated in eastern Hungary.
How large is the Jewish community in Budapest?
Between 75,000 and 100,000 Jews live in Hungary today, with the large majority in Budapest. The community maintains active synagogues, schools, and cultural institutions. The Dohany Street Great Synagogue, seating 3,000, is the largest synagogue in Europe. Before the Holocaust, approximately 825,000 Jews lived in Greater Hungary.
Are there any mosques in Hungary from the Ottoman period?
A few Ottoman-era religious structures survive. The minaret in Eger, standing 40 meters tall, is one of the northernmost Ottoman minarets in Europe. The Mosque of Pasha Qasim in Pecs retains its dome and minaret base, though it now functions as a Catholic church. Ottoman public baths in Budapest, including the Rudas and Kiraly baths, also date from this period.
Is Hungary a religious or secular country?
Hungary shows both tendencies. While 73 percent of census respondents who answered the religion question claimed a denomination, 27 percent reported no religion, and 40 percent of the total population declined to answer. Regular church attendance runs well below nominal affiliation. Hungary’s 2011 constitution includes references to Christianity’s role in the nation’s history, but the state maintains separation of church and government in practice.
