Uruguay is the least religious country in Latin America: roughly four in ten Uruguayans report no religion, around a third identify as Catholic, and evangelical Protestants account for something over ten per cent, with small Afro-Umbandist and Jewish communities. Every neighbour in the region is substantially more religious, and the gap is not recent — it was engineered deliberately, beginning more than a century ago.
Why the Church Was Weak From the Start
Uruguay never had the institutional Catholicism that shaped Peru, Mexico or Colombia. There were no great mineral riches to fund cathedrals, no dense settled indigenous population for the missionary orders to convert and administer, and no viceregal capital. The Banda Oriental was a cattle frontier, contested between Spain and Portugal, thinly populated and loosely governed.
The Jesuit missions that did organise indigenous populations on a large scale were mostly across the river in what became Paraguay and Argentina, and the order was expelled from Spanish territory in 1767 in any case. By independence, the church in Uruguay had few clergy, little land and limited reach into the countryside.
Then came mass European immigration in the nineteenth and early twentieth centuries — Spanish, and very large numbers of Italians — which brought both nominal Catholics and a considerable population of anarchists, socialists, freemasons and freethinkers who were actively anticlerical. Montevideo acquired a secular political culture before it acquired a strong church.
Batlle, and the Separation of 1917
The decisive figure is José Batlle y Ordóñez, twice president between 1903 and 1915, whose reform programme built one of the earliest welfare states in the world and who was personally and publicly hostile to the Catholic Church.
The constitution of 1917, which took effect in 1919, separated church and state completely — the first such separation in Latin America. Catholicism ceased to be the state religion, public funding ended, and the church became a private association with no constitutional privileges.
The individual measures are the more telling part of the record. Crucifixes were removed from public hospitals in 1906. Religious references were struck from official oaths. Religious instruction was removed from state schools in 1909. Divorce was legalised in 1907, and in 1913 Uruguay became the first country in the world to allow a woman to obtain a divorce on her own will alone, without proving cause.
The Schools That Did the Work
The separation of 1917 was possible because the ground had been prepared forty years earlier in the classroom. José Pedro Varela, a young reformer influenced by American common-school ideas, pushed through the Law of Common Education in 1877, which made primary schooling free, compulsory and — the decisive word — secular.
Uruguay was among the first countries anywhere to combine all three, and the effect compounded. Successive generations passed through state schools in which religion was simply not a subject, taught by teachers trained in a normal school system that treated secularism as a professional norm rather than a political position.
By the time Batlle moved against the church's constitutional position, a substantial part of the electorate had never received religious instruction in a classroom. That is why the reforms met little resistance and why nobody has seriously tried to undo them: the constituency that would demand it was never formed.
The Holidays That Were Renamed
In 1919 the state renamed the religious holidays it continued to observe, and the new names are still the official ones:
- 25 December is Día de la Familia, Family Day, not Christmas.
- Holy Week is Semana de Turismo, Tourism Week — also widely called Semana Criolla for the gaucho rodeo held during it in Montevideo.
- 6 January, Epiphany, is Día de los Niños, Children's Day.
- 8 December, the Immaculate Conception, is Día de las Playas, Beach Day.
What makes this more than symbolism is that the names took. Uruguayans say Semana de Turismo without irony or political intent, and the week is associated with the countryside, asado and the rodeo rather than with the Passion. Uruguay is also the only country in the region where Holy Week is when the national gaucho festival happens.
The Catholic Church Today
The church that remains is small and unsubsidised. Mass attendance is low — well under ten per cent of the population attends weekly by most surveys — and the priest shortage is severe, with many parishes served by foreign clergy.
Its public interventions carry less weight than anywhere else in the region. Uruguay legalised abortion in the first trimester in 2012, same-sex marriage in 2013 and the regulated production and sale of cannabis in the same year, in each case over Catholic objection and without the political cost that similar measures carried elsewhere in Latin America.
The church has adapted by concentrating on social work in the poorer neighbourhoods of Montevideo, where its schools and community programmes operate alongside those of the state.
Evangelical Growth on the Edges
The one growing Christian sector is evangelical and Pentecostal, which has risen from a very small base to somewhere above ten per cent, concentrated in the working-class peripheries of Montevideo and in the northern departments along the Brazilian border, where Brazilian churches have crossed over.
The growth follows the regional pattern — small congregations, lay pastors, healing and deliverance, strict codes of conduct, and an emphasis on recovery from addiction and family breakdown — but it is occurring in a society whose default is secular rather than Catholic, so converts are more often coming from no religion than from the church.
Evangelical political organisation has emerged more recently and remains modest by Brazilian or Central American standards.
Iemanjá on the Second of February
The largest single religious gathering in Uruguay is not Christian. Every 2 February, tens of thousands of people descend on Playa Ramírez in Montevideo and other beaches along the Río de la Plata for the feast of Iemanjá, the Yoruba-derived orisha of the sea.
Devotees dressed in white and blue dig small pits in the sand, light candles, and float offerings out on the water: miniature boats carrying flowers, perfume, melons, rice, mirrors and combs. Drumming continues through the night. If an offering returns to shore, the goddess has declined it.
The religion behind it is Umbanda, developed in Brazil from Yoruba and Kongo traditions blended with Catholicism and Kardecist spiritism, which crossed into Uruguay in the middle of the twentieth century and spread rapidly. Afro-Uruguayan religious practice today is more visible than at any point since the abolition of slavery, and it is entangled with Candombe, the drumming tradition of Montevideo's old conventillos, which UNESCO inscribed in 2009.
Census figures for Umbanda are small — a few per cent at most — but attendance at the beach on 2 February suggests participation far exceeding formal affiliation, which is a familiar pattern in Afro-Atlantic religion.
The Jewish Community
Uruguay's Jewish population, built by immigration from Eastern Europe before and after the Second World War and by Sephardic arrivals from the Ottoman lands, was proportionally among the largest in Latin America, numbering perhaps 50,000 at its peak.
It has declined through emigration to Israel, the United States and elsewhere, particularly after the economic crisis of 2002, to somewhere between 12,000 and 20,000 today, almost entirely in Montevideo. The community maintains synagogues, schools and cultural institutions, and Uruguay was the first Latin American country to recognise the State of Israel.
Why Uruguay and Not Argentina
The comparison with its neighbour is the sharpest way to see what happened. Argentina received the same immigration, from the same countries, at the same time, and its capital sits an hour away across the estuary. Yet Argentina retained a constitutionally privileged Catholic Church until late in the twentieth century, produced a pope, and remains substantially more religious.
The difference is largely institutional. Argentina had a colonial church with property, universities and a place in the state that survived independence. Uruguay's was weak enough that a determined reformist president could detach it in a decade. Once separated, the church had no mechanism to rebuild its position, and each generation was educated in schools from which religion had been removed.
Chile and Cuba underwent partial versions of the same process; neither went as far or as early.
A Secularism That Nobody Is Fighting About
The striking feature of Uruguayan secularism is how uncontroversial it is. There is no significant movement to restore religious instruction to state schools, to rename the holidays back, or to give the church public funding. Religious leaders participate in public life as individuals and are heard politely.
The state is not hostile to religion; it simply does not engage with it. Public ceremonies have no chaplain, presidents are sworn in without a Bible, and the census question about religion attracts the largest "none" response in the region without anyone treating that as a crisis.
For a continent where religion and politics remain tightly bound, Uruguay is the outlier that shows how differently things could have gone. More on the country is in our Uruguay country guide, its neighbours in our South America continent guide, and the basics in where Uruguay is.
