To a visitor flying in from anywhere west of Berlin, the three Baltic states look interchangeable. Three small countries lined up along the eastern Baltic coast, each occupied by the Soviet Union, each independent again since 1991, each in the EU since 2004, all three speaking languages outsiders cannot tell apart, all three with snow in winter and wooden houses and pine forests and storks on the chimney.
This is a wonderful and forgivable mistake, but it is a mistake. Once you scratch any deep aspect of culture — language, food, music, architecture — the three countries diverge sharply. Religion is the most striking case of all. By any measure you can think of, Lithuania, Latvia, and Estonia are religiously about as different from each other as three small neighbouring countries can be.
Lithuania is one of the most Catholic countries in Europe. Roughly three-quarters of its population identifies as Roman Catholic — a higher share than Italy, France, or Spain. The Pope is a major cultural figure. The country is dotted with crosses and shrines.
Latvia is split three ways. It is the only country in the European Union with no clear religious majority — Lutheran, Catholic, and Orthodox in roughly that order, with a substantial non-religious population added on top. The Lutherans are clustered in the west and centre; the Catholics in the east; the Orthodox among the Russian-speaking minority everywhere.
Estonia is, by some measures, the least religious country in the world. Around 45% of Estonians identify with no religion at all. Of those who do, the largest groups are roughly equal: Russian Orthodox (mostly ethnic Russians) and Lutheran (mostly ethnic Estonians). Only 14% of Estonians say religion is important in their daily lives — the lowest figure recorded in the European Social Survey.
How did this happen? Three neighbouring small countries, sharing centuries of common Soviet experience and similar pre-Christian Baltic-Finnic pagan roots, ending up so different? The answer is in the history. Let me walk through it.
Pre-Christian Baltic religion: what was here before
For roughly a thousand years, while most of Europe was being Christianised, the eastern shore of the Baltic Sea was the great holdout. The Latvians and Lithuanians (Baltic peoples, speaking Indo-European languages of the Baltic branch) and the Estonians (a Finnic people, related linguistically to Finns and Hungarians) all practised forms of nature-based polytheism well into the medieval period.
Latvian and Lithuanian paganism shared a Baltic pantheon — sky god Dievs (Lithuanian Dievas), the goddess of fate Laima, the earth-mother Māra / Žemyna, the thunder god Pērkons / Perkūnas, and many more. The forests had spirits, the rivers had spirits, the household had spirits. There were sacred groves where animals were not hunted and trees were not cut. Folk songs (the Latvian dainas, of which over a million were eventually transcribed) preserved these beliefs in coded form, even after centuries of Christianity.
Estonian pagan belief was structurally different — Finnic rather than Baltic — with its own pantheon, its own sky-god Taara, its own veneration of sacred places (hiis), and its own cosmology centred on natural sites rather than abstract deities. Like the Baltic peoples, the Estonians embedded their religion in their daily relationship with the forest, the field, and the sauna.
What happened next is determined entirely by who arrived to convert them, when, and how violently.
The Northern Crusades: how Latvia and Estonia became Christian
In the late 12th century, the Catholic Church and the kingdoms of northern Europe — German, Danish, Swedish — turned their attention to the last pagans in Europe. Pope Celestine III formally authorised what became known as the Northern Crusades in 1195, and the long, brutal process of Christianising the eastern Baltic by force began.
Latvia and Estonia were the easier targets. The land was flatter, the population smaller and more dispersed, no centralised state to coordinate resistance. A German monk named Meinhard arrived at the mouth of the Daugava River in 1184 and built a small church at Ikšķile. Peaceful conversion did not work. By 1202 the Bishop of Riga had founded a militant order — the Brothers of the Sword — to convert the locals at sword-point. Riga itself was founded as a crusader colony in 1201.
What followed was nearly a century of grinding warfare. The Livonian Crusade against the Latvians and Estonians ran roughly from 1198 to 1290. Whole tribes were exterminated, villages burned, sacred groves cut down, pagan priests killed. The Estonians revolted repeatedly — the famous St. George’s Night Uprising of 1343 was a last desperate attempt to overthrow German rule and return to the old gods, and it was crushed with characteristic violence. By the late 13th century the indigenous populations had been forcibly baptised and a German military aristocracy had installed itself permanently as the ruling class of Livonia (modern Latvia and Estonia).
This is the first key point for understanding modern Baltic religion: in Latvia and Estonia, Christianity arrived as a foreign occupation. The native peoples were converted by violence, ruled by a German Catholic nobility for centuries afterwards, and remained tenant peasants on land owned by Baltic Germans. Christianity in Latvia and Estonia was the religion of the conquerors. This matters enormously when we get to the modern period.
Lithuania: the holdout
Lithuania was a different story entirely.
While the Latvians and Estonians were being Christianised by force, the Lithuanians did something extraordinary: they built a state, expanded it, and stayed pagan for another 200 years.
In the 13th century, while the Teutonic Knights were grinding their way through Latvia, the Lithuanian dukes — Mindaugas, Gediminas, Algirdas, Kęstutis — consolidated a state that eventually grew into the largest country in Europe, the Grand Duchy of Lithuania, stretching from the Baltic Sea to the Black Sea. This pagan state held off the Teutonic Order in repeated wars, conducted complex diplomacy with the Catholic West and the Orthodox East, and used its religious ambiguity as a political tool. Mindaugas accepted baptism in 1251 to gain a royal crown from the Pope, then quietly abandoned Christianity again. Gediminas wrote letters promising baptism in exchange for political concessions and never delivered. The Lithuanian dukes kept their options open for over a century.
The conversion finally came in 1387, and even then it was a political deal. Grand Duke Jogaila married Queen Jadwiga of Poland, became King of Poland (as Władysław II Jagiełło), and accepted Catholicism for himself and his people as part of the bargain. Vilnius Cathedral was built on the site of a demolished pagan temple. Sacred groves were felled. The eternal fire of Perkūnas in the temple at Vilnius was extinguished.
But — and this is critical — even Jogaila’s official Christianisation of Lithuania left Samogitia (the western region, Žemaitija in Lithuanian) unconverted until 1413. Lithuanian villages in remote regions continued to practise the old religion well into the 16th century. The Christianisation of Lithuania was the slowest and gentlest in Europe.
This is the second key point: Lithuania was Christianised on its own terms, by its own ruler, as part of a strategic alliance with Poland that gave it Western legitimacy without erasing its political independence. Catholicism in Lithuania became, almost from the start, a marker of national identity rather than foreign occupation. To be Lithuanian was to be Catholic, in a way that being Latvian or Estonian was never quite to be Lutheran.
The Reformation: Estonia and most of Latvia turn Lutheran
The third great religious rupture came in the 16th century with Martin Luther’s Reformation. This is where the religious paths of the three countries finally split definitively.
In Latvia and Estonia, the Baltic German nobility — the actual landowning, governing class — converted to Lutheranism in the 1520s and 1530s, and dragged their peasant populations along with them. The first Lutheran sermon in Riga was preached in 1521. By 1561, when the old Livonian Order finally collapsed, most of Latvia and Estonia was officially Lutheran. The first book ever printed in Estonian was a Lutheran catechism, in 1535. By the early 20th century, around 80% of Estonia and 55% of Latvia were Lutheran.
Lithuania, meanwhile, was Catholic and stayed Catholic. The Reformation made some inroads among the Lithuanian-Polish nobility, but the Counter-Reformation — driven hard by the Jesuits, who arrived in Vilnius in 1569 and built one of the great universities of Eastern Europe there — pushed it back almost entirely. Catholicism became further entrenched as a marker of Lithuanian and Polish identity against the Lutheran Germans to the north and the Orthodox Russians to the east.
The exception within Latvia was Latgale, the eastern region. Latgale spent the late 16th and 17th centuries inside the Polish-Lithuanian Commonwealth rather than under Swedish or German rule, and so it stayed Catholic when the rest of Latvia turned Lutheran. To this day, Latgale is the Catholic heartland of Latvia. If you visit the Aglona Basilica in eastern Latvia, you are in essentially a Polish-Lithuanian Catholic landscape, transposed onto Latvian soil. Driving from Riga to Daugavpils, you pass an invisible religious border somewhere east of Krāslava, beyond which the Lutheran churches give way to Catholic ones.
Russian Orthodoxy arrives
The fourth layer arrived with the Russian Empire. Latvia and Estonia were absorbed into Russia after the Great Northern War (1721); Lithuania was absorbed in the partitions of Poland (1772–1795). For the next two centuries, all three countries lived under Russian Orthodox tsars who actively encouraged Orthodox missionary work, settlement of Russian Orthodox populations, and (sometimes) outright pressure for Latvian and Estonian peasants to convert to Orthodoxy as a path out of German feudal control.
Some did. In the 1840s there was a wave of Latvian and Estonian peasant conversions to Russian Orthodoxy, partly driven by hopes of better treatment under a tsar than under their German lords. These converts and their descendants make up part of the Latvian Orthodox population today, though most modern Latvian Orthodox are descendants of Russian-speaking settlers from the Tsarist and Soviet periods.
Russian Orthodoxy in Lithuania remained marginal — a religion of the Russian minority and some borderland communities — because Lithuanian Catholic identity was simply too strong to displace.
The 20th century: independence, occupation, atheism
Each country emerged briefly independent between the world wars (1918–1940), with religious life roughly as the long history had left it: Lithuania heavily Catholic, Latvia majority Lutheran with a Catholic east and an Orthodox minority, Estonia overwhelmingly Lutheran. Each had its own national church.
Then came Soviet occupation (1940–1941, 1944–1991, with German occupation in between). Soviet policy was state atheism: church property confiscated, clergy arrested or murdered, religious education banned, theological seminaries closed, public religious practice driven underground.
But the three countries’ religious traditions handled the pressure differently, and this is what produced the modern picture.
In Lithuania, the Catholic Church became — quietly, then loudly — the central institution of national resistance. Catholic identity and Lithuanian identity were so fused that suppressing one meant suppressing the other, and the Soviet regime never fully managed it. The famous Hill of Crosses north of Šiauliai, where Lithuanians erected crosses by the tens of thousands as acts of defiance against the Soviet authorities (which bulldozed the hill at least three times — 1961, 1973, 1975 — and each time the crosses came back), is the most visible monument to this resistance. When Pope John Paul II visited the site in 1993, he treated it as a kind of sacred ground of Catholic survival. Lithuanian Catholicism came out of the Soviet period weakened but still central to Lithuanian identity.
In Latvia, the same pressure came down on a much more divided religious landscape. The Latvian Lutheran Church, already historically associated with the German nobility, lacked the deep popular legitimacy that Lithuanian Catholicism had. Many Latvians had complicated feelings about “their” church even before the Soviets arrived. Soviet suppression hit Lutheranism harder than it hit Catholicism (the Catholic Latgale region, with strong Polish-Lithuanian connections, held out better), and the result was a postwar Latvia where the gap between Lutheran and Catholic narrowed dramatically, and a large fraction of the population — having lost the habit of religion — never picked it back up.
In Estonia, the suppression effectively destroyed organised religion as a mass phenomenon. Estonian Lutheranism, like Latvian Lutheranism, had always carried the historical baggage of German foreign rule. When the Soviets came down on it, very little popular resistance defended it. The chain of religious tradition broke in most Estonian families, and in the 50 years that followed, secularism became the cultural default. This is why Estonia today is one of the most secular countries on Earth — not because Estonians made some sudden Enlightenment decision, but because the existing religious institutions were already weakly tied to popular identity and the Soviet period broke what remained.
Where things stand today
The most recent reliable surveys (Pew Research, Latvian Ministry of Justice, Estonian Council of Churches, Lithuanian census) give roughly the following picture, as of 2022–2024:
Lithuania is around 74% Catholic, with about 4% Russian Orthodox (mostly the small ethnic-Russian minority), small Lutheran and Old Believer populations, and around 10–15% non-religious. It is the only majority-Catholic country among the three Baltic states, and the world’s northernmost Latin Catholic-majority nation. Pope Pius XII called it “the northernmost outpost of Catholicism in Europe” in 1939, and that hasn’t changed.
Latvia is, by Ministry of Justice 2022 data, roughly 37% Lutheran, 19% Catholic, 13% Latvian Orthodox, with the remaining 30%+ non-religious or other. The geographic split is clear: Lutheran in Riga, Vidzeme, and Kurzeme; Catholic in Latgale; Orthodox among the Russian-speaking minority everywhere. Surveys differ on the exact percentages, but every survey shows Latvia as a three-way religious country with no majority. About 7% of the population attends services regularly — quite low.
Estonia is approximately 14% Lutheran, 13% Russian Orthodox, less than 3% Catholic, around 45% no religion, with the remainder split among other Christian denominations, neopagans, and various smaller groups. Estonia is regularly identified by the Gallup International “Religion Index” as one of the world’s least religious countries by self-reported importance of religion, alongside the Czech Republic, Sweden, and a handful of others.
If you want a single sentence: Lithuania kept its religion through everything; Estonia lost it; Latvia ended up split.
A recent turn: the Orthodox split from Moscow
One of the most striking recent stories — barely noticed outside the region — is what happened to Baltic Orthodoxy after the Russian invasion of Ukraine in February 2022.
Russian Orthodoxy in the Baltic states had always been institutionally subordinate to the Moscow Patriarchate. In 2022, when Patriarch Kirill of Moscow publicly endorsed the war and described Russian soldiers killed in Ukraine as making “sacrifices in the name of the fatherland” that “redeemed their sins,” the political position of his subordinate churches in NATO countries became immediately untenable.
Latvia acted first. On 8 September 2022, the Latvian parliament passed a law making the Latvian Orthodox Church autocephalous — fully independent of the Moscow Patriarchate. It was, in effect, a state-imposed schism, justified on national security grounds. Moscow rejected the move; the Latvian Orthodox Church reluctantly complied. The split is unrecognised by most of the global Orthodox communion, but in legal and practical terms, the Latvian Orthodox Church is no longer Russian.
Estonia and Lithuania have been moving in similar directions, with their respective Orthodox churches navigating jurisdictional changes more slowly and through different mechanisms. The Estonian government has been pressuring the Estonian Orthodox Church of the Moscow Patriarchate to break its ties; in Lithuania, a small group of priests transferred to the jurisdiction of the Ecumenical Patriarchate of Constantinople in 2022.
For visitors interested in the religious texture of the region, this is a live story. The Orthodox cathedrals you walk past in Riga, Tallinn, and Vilnius are at the centre of an ongoing geopolitical and theological reordering that is genuinely making history.
The pagan revival
The other genuinely interesting modern story is the slow revival of pre-Christian Baltic religion — not as serious mass religion, but as a culturally significant minority movement.
In Latvia, the movement is called Dievturība (literally “those who hold to Dievs”), founded in 1925 by Ernests Brastiņš and based on the dainas — the corpus of Latvian folk songs that preserve the pre-Christian cosmology. Repressed under the Soviets, exiled to communities in North America, and revived in Latvia after 1990, Dievturība received unprecedented legal recognition in 2024 through a new Latvian law that endorses its claim of continuity with Latvia’s ancient past.
In Lithuania, the movement is called Romuva, founded by the philosopher Vydūnas in the early 20th century and carried forward after Soviet repression by the high priest Jonas Trinkūnas, consecrated as the country’s first krivis (pagan priest) in 600 years in 2002. Lithuania’s Catholic establishment resisted official recognition of Romuva for decades, but in 2024, under pressure from the European Court of Human Rights, the state finally granted it legal status as a recognised religion.
In Estonia, the indigenous religion is called Maausk (literally “earth faith”) and Taaraism (named for the sky-god Taara). It has fewer adherents than the Latvian and Lithuanian movements but has grown significantly since the 1990s. A 2014 University of Tartu study found that 61% of Estonians believed neopaganism was the “true” religion of Estonia — a striking number, even if most of those Estonians don’t actually practice it.
The numbers of formal adherents in all three movements remain small (a few thousand each), but the cultural footprint is wider than the membership: many Latvians and Lithuanians who attend Catholic or Lutheran services for weddings and funerals will quietly observe pagan-rooted seasonal festivals — the summer solstice (Jāņi in Latvian, Joninės in Lithuanian, Jaanipäev in Estonian) is celebrated more enthusiastically than Christmas in many households, and is openly understood to be a survival of the pre-Christian solar year.
What you’ll see as a visitor
If you spend time in all three countries, the religious differences become physically visible.
In Lithuania, you see crosses everywhere. Cemeteries are full of them, hilltops are crowned with them, the Hill of Crosses near Šiauliai has hundreds of thousands. Vilnius Old Town is a textbook of Catholic Counter-Reformation architecture: Baroque churches on every block, the Gate of Dawn with its miraculous icon of the Virgin, the white cathedral on Cathedral Square where every Lithuanian president still takes the oath. On Sundays, churches are full. People cross themselves passing a roadside shrine.
In Latvia, you see religious diversity laid out geographically. Lutheran spires in Riga and the western towns. The great Baroque Catholic basilica at Aglona in the Latgale countryside. Russian Orthodox onion domes — the magnificent Nativity of Christ Cathedral in Riga, gold and white in the centre of the city — serving the Russian-speaking minority. Wooden Old Believer prayer houses in the suburbs of Riga and Daugavpils. And, equally striking, plenty of beautiful old churches with empty Sunday congregations.
In Estonia, you see the historical Lutheran heritage — the great medieval St. Olaf’s Church in Tallinn, the Dome Church on Toompea Hill — but the churches are largely museum pieces. Sunday services are sparsely attended. Most Estonians visit a church for weddings, funerals, and the occasional Christmas Eve service, but the relationship is cultural rather than devotional. Russian Orthodox cathedrals (the Alexander Nevsky Cathedral in Tallinn) are active mostly among the Russian-speaking population. The dominant religious mood is friendly secularism.
The deeper pattern
What I find genuinely interesting about all this is what it tells you about how religion actually works in the long run.
Lithuania kept its religion because Catholicism arrived late and on Lithuanian terms — it was associated from the start with national sovereignty and political independence, never with foreign occupation. Even after centuries of Russian rule and a brutal Soviet occupation that targeted the Church specifically, Lithuanian Catholicism survived because Lithuanians experienced Soviet attacks on the Church as attacks on Lithuania itself.
Estonia lost its religion because Lutheranism arrived as part of a foreign aristocratic occupation that lasted seven centuries. When the Soviets attacked the Lutheran Church in the 1940s, very few Estonians experienced the attack as personal. The Church was the Germans’ church, then the Russians’ church to suppress, and most Estonians shrugged.
Latvia ended up in between because Latvia is, in some sense, two countries religiously — a Lutheran west whose story is closer to Estonia’s, and a Catholic east whose story is closer to Lithuania’s. Plus an Orthodox minority that doesn’t quite belong to either narrative. The split was already there before the Soviets arrived; it’s still there today.
And underneath all three, the pagan substrate persists — in folk songs, in solstice fires, in the protected sacred groves that Lithuanian and Latvian forestry law still recognises, in the names of the days of the week (the Latvian Thursday, ceturtdiena, was historically Pērkona diena — Thunder God’s day — long after Christianisation).
On our excursions
Religion is a thread that runs through almost every excursion we run, whether we’re explicitly talking about it or not. The Hill of Crosses excursion is, fundamentally, about Lithuanian Catholic resistance to Soviet rule — though we also try to explain the deeper pagan continuity that puts the crosses in such a particular emotional context. Rundāle Palace and the Bauska region take you through Baltic German Lutheran territory, with the great old churches that were the centres of the German manorial estates. Ęemeri Bog and Jūrmala are rich in pre-Christian sacred-landscape associations — the Latvian relationship to the bog and the sea is deeply pre-Christian and never really got displaced. And Sigulda and Cēsis put you in the heartland of medieval crusader territory, where you can still walk the walls of the castles built specifically to enforce the Christianisation of the Latvian peoples by force.
If you have specific religious-history interests — Catholic, Lutheran, Orthodox, pagan, or just the curiosity of seeing three closely linked countries that took completely different religious paths — let us know. Daiga can adjust any of our standard excursions to spend more time on the religious dimension, and there are several specialised stops (Aglona Basilica in Latgale; the wooden Old Believer churches of the Daugavpils region; the pagan sacred groves preserved within Ęemeri National Park) that we can build into a custom day if there’s interest.
The story is, in the end, more interesting than the simple fact of three small countries practising three different religions. It’s the story of how religious geography is built up over a thousand years, how it survives or doesn’t survive political pressure, and how the past keeps showing up in the present in ways that the people living it sometimes don’t even notice. The three Baltic countries are, in this respect, a small but unusually clear laboratory.
Comparative religion is the kind of thread we weave through our tours when guests are interested. If you want this story told inside the actual churches and cathedrals across all three Baltic capitals, get in touch with your dates and we'll design the route.
