On 3 May 1791, in the Royal Castle in Warsaw, a constitution was passed. It was the second written national constitution in the world, and the first in Europe. It tried to drag the Polish-Lithuanian Commonwealth — then the largest state in continental Europe by area, and one of the most paralysed politically — into a recognisably modern political form. Within fourteen months, Russian troops had crossed the border, and within four years, Poland had ceased to exist as a state.
The Constitution was in force for just over a year. The Polish state it tried to save was extinguished from European maps for 123 years afterwards. And yet, more than two centuries later, 3 May is one of Poland's two great national days — the date around which the country organises its identity, its symbols, and a substantial part of its public memory.
That trajectory — short legislative life, immediate suppression, generations of forbidden observance, eventual restoration — is the story of 3 May, and it is, in a particular way, also the story of how Poland thinks about itself.
TL;DR: The Constitution of 3 May 1791 was the second written national constitution in the world, the first in Europe. It restructured the Polish-Lithuanian Commonwealth — abolishing the liberum veto, separating powers, extending rights to townspeople — and was suspended by Russian intervention within fourteen months. For 123 years of partition, celebrating it was illegal in most of Poland. The day was restored after independence in 1919, banned again under the PRL, and reinstated as a national holiday in April 1990.
The setting: a country running out of time
To understand why the Constitution of 3 May was written, you have to understand how badly the Polish-Lithuanian Commonwealth was failing in the 1780s.
The Commonwealth had been, for two and a half centuries, one of Europe's most distinctive political experiments. It was a real elective monarchy, where the king was chosen by the nobility rather than inheriting the throne. Its parliament — the Sejm — was unusually powerful for its era. Its religious tolerance was, by the standards of the time, remarkable: Catholics, Protestants, Eastern Orthodox Christians, Jews, and Muslim Tatars all lived under varying degrees of legal protection. At its territorial peak, it stretched from the Baltic to the Black Sea and from the gates of Berlin nearly to Moscow.
By the mid-18th century, all of this was breaking down. The system that had once made the Commonwealth distinctive had calcified into one of the slowest-moving political machines in Europe. The most damaging single feature was the liberum veto — a parliamentary procedure that allowed any single nobleman in the Sejm to nullify all legislation by shouting "Nie pozwalam!" ("I do not allow it!"). Originally intended as a check on majoritarian abuse, it had become a tool of foreign manipulation. By the 1780s, Russia and Prussia were routinely paying individual Polish nobles to veto reforms that would have strengthened the Polish state. Sejm sessions ended in chaos and emptiness, year after year.
The First Partition of Poland in 1772 — when Russia, Prussia, and Austria carved off about a third of Polish territory among themselves — was the wake-up call. It became clear to a substantial faction of the Polish elite that the Commonwealth would simply cease to exist if it could not reform itself. The question was whether reform was possible at all, given that any attempt to strengthen the Polish state would be seen by neighbouring powers as a threat.
The answer was the Sejm Czteroletni (Four-Year Sejm), which opened in 1788 and met until 1792. It convened under the protection of a temporary distraction — Russia, Prussia, and Austria were preoccupied with the Russo-Turkish War. Reformist deputies seized the moment. Working with King Stanisław August Poniatowski (the last king of Poland, who was a complicated figure but capable of reform when given political room), Hugo Kołłątaj, and Ignacy Potocki — they spent four years writing the most ambitious constitutional reform in European history to date.
The Constitution of 3 May was the result.
What did the Constitution of 3 May actually do?
The Constitution of 3 May 1791 — formally titled Ustawa Rządowa ("Government Act") — was a 11-article document that fundamentally restructured how the Polish-Lithuanian state was governed. The core changes:
What the Constitution of 3 May Changed
Eight major shifts in how the Polish-Lithuanian Commonwealth was governed.
| What it changed | Before 3 May 1791 | After 3 May 1791 |
|---|---|---|
| Legislative deadlock | Any one noble could kill legislation via liberum veto | Liberum veto abolished — majority rule in the Sejm |
| The monarchy | Kings were elected, often by bribed foreign-backed candidates | Monarchy made hereditary in the House of Saxony |
| Separation of powers | Blurred — king and Sejm tangled together | Explicit separation into legislative, executive, and judicial branches |
| Townspeople's rights | Minimal political standing | Extended political rights, right to own land, ennoblement possible |
| The peasantry | Personal serfdom, subject to noble jurisdiction | Taken "under the protection of the law" (vague but meaningful) |
| Religious position | Broad but unstable toleration | Catholicism declared the dominant faith; other faiths still tolerated |
| Confederations | Armed noble confederations could legally override the state | Banned — no more private armies overruling parliament |
| Executive government | Largely absent | Created the "Straż Praw" — the Guardians of the Laws cabinet |
The reform was not a clean break with the old order — the nobility retained substantial privilege, and the peasantry was given protection rather than equality — but for 1791, it was extraordinarily progressive. The Constitution combined the Enlightenment political theory then current in France and the United States with the older Polish republican tradition that had survived in the Commonwealth's parliamentary culture, even as the institutional framework around it crumbled.
The document was passed on 3 May in a single dramatic Sejm session. Reformist deputies had quietly summoned a quorum during the Easter recess, when many opponents were out of town. The vote took place under the eye of an aroused Warsaw crowd that had filled the streets around the Royal Castle. The Constitution was adopted by acclamation. King Stanisław August swore an oath to it the same day.
Was it really the second written constitution in the world?
Yes — though as with most superlatives, the honest version requires a few asterisks.
The United States Constitution was adopted on 17 September 1787 and ratified by enough states to take effect on 4 March 1789. The Polish Constitution was adopted on 3 May 1791. The French Constitution of 1791 was adopted on 3 September 1791 — four months after the Polish one.
So the formulation "second in the world, first in Europe" is technically correct, given the conventional definition of "constitution" as a single written document framing the political order of a sovereign nation-state. Earlier political documents — Magna Carta of 1215, the English Bill of Rights of 1689, the Swedish Instrument of Government of 1772 — are sometimes cited as constitutional precursors, but they are not generally classified as "constitutions" in the modern sense (single written framing documents adopted by representative bodies).
What's worth noting is that the Polish constitutional tradition was, in some respects, older than that. The Henrician Articles of 1573 — agreed at the first royal election after the death of Sigismund II Augustus — were a written framework binding the king to specific limits on royal power. They were a constitutional document in everything but name, and they predated all of the others. The 1791 Constitution was, in part, an attempt to update and modernise this older Polish constitutional thinking.
The international response was striking. Edmund Burke, the Anglo-Irish parliamentarian and political theorist, called the Polish Constitution "the noblest benefit received by any nation at any time" — a remarkable assessment given Burke's general scepticism toward constitutional revolutions, and given his particular hostility to the French Revolution then unfolding next door. Thomas Jefferson watched developments closely from Philadelphia. The Constitution was rapidly translated into French, English, German, and other European languages.
None of this saved it.
Why did the Constitution last only fourteen months?
The Constitution of 3 May was suspended in July 1792, when King Stanisław August acceded to the Targowica Confederation — a group of conservative Polish magnates who, with active Russian backing, declared the constitutional reforms void.
The mechanics: in May 1792, while the Polish state was still organising itself under the new Constitution, Russian armies crossed the border. The Russian government had decided that a strengthened, modernising Poland on its western flank was unacceptable. The Polish-Russian War of 1792 lasted only a few months. The Polish army, freshly reorganised but still small relative to the Russian forces, fought hard but was overwhelmed. Tadeusz Kościuszko — who would later lead the 1794 uprising — distinguished himself in battles at Dubienka and Zieleńce, but the strategic situation was hopeless.
By July, King Stanisław August had decided that further resistance would cost more than the Constitution was worth. He acceded to the Targowica Confederation. The Constitution was suspended. The reforms of the Four-Year Sejm were rolled back. The reformist leaders fled to Saxony, France, or further into exile.
One year later, in 1793, came the Second Partition of Poland. Russia and Prussia took massive additional territories. The remaining Polish state was reduced to a rump.
In 1794, Kościuszko returned and launched a national uprising — the Insurekcja Kościuszkowska — to restore the Constitution by force. The uprising was extraordinary in its breadth (Kościuszko issued the Universał Połaniecki, conditionally freeing serfs in exchange for military service) and its drama (the Battle of Racławice with peasant scythe-wielders and the Praga massacre of Warsaw civilians by Russian forces). It failed.
In 1795 came the Third Partition. The remaining Polish territory was divided among Russia, Prussia, and Austria. The Polish-Lithuanian Commonwealth ceased to exist as a state.
The Constitution of 3 May had been in force for fourteen months. The state it tried to save lasted three more years. It would be 123 years before there was a sovereign Polish state again.
This sequence — reform, resistance, suppression, and the collapse of statehood that followed — is part of why 3 May carries such weight in Polish memory. It was not a constitutional success story. It was a brave, doomed attempt that failed against overwhelming external power. The dignity is in the attempt, and in the fact that it was, on its own terms, a real constitutional advance.
How did 123 years of forbidden anniversaries work?
From 1795 to 1918, Polish territory was divided among three partitioning powers, each with its own attitude toward the memory of 3 May.
In the Russian partition (the largest, including Warsaw and most of central and eastern Poland), public observance of 3 May was prohibited. The date was associated with rebellion against Russian authority, and Russian governors-general regarded any commemoration as subversive. Schools could not teach about it. Newspapers could not write about it. Public gatherings on the date were broken up. A Pole who attempted a public observance could face fines, arrest, exile to Siberia, or in the worst cases, capital punishment.
In the Prussian partition (including Greater Poland and Pomerania), the response was less violent but more systematic — a long-term Germanisation programme aimed at suppressing Polish identity altogether. Public observance was forbidden, Polish-language schooling was systematically dismantled, and Polish landowners were pressured to sell their estates to German settlers.
In the Austrian partition (Galicia, including Kraków and Lwów), the situation was different from the 1860s onward. After Austria-Hungary's defeats in 1866 and 1867, Vienna granted substantial autonomy to Galicia. By the 1870s, Polish was the official language in Galician schools and offices, and Polish cultural and political life flourished openly. Constitution Day was observed publicly in Kraków and Lwów from the 1880s onward, with Masses, parades, and academic ceremonies. This is why so much late-19th-century Polish national symbolism — including the standardisation of the 3 May observance itself — has Galician origins.
For Poles in the Russian and Prussian partitions, observance was private and risky. People held quiet family gatherings. Some hung the white-and-red flag inside, behind shutters. Polish Catholic parishes occasionally found ways to mark the date through Marian devotions on or near 3 May, since the Feast of the Blessed Virgin Mary, Queen of Poland was permitted as a religious observance even where the political holiday was banned.
This is also where the Polish diaspora becomes structurally important. In the United States — particularly in Chicago, where the largest Polish-American community had formed by the 1880s — the Polish Constitution Day Parade has been held annually since 1892. Chicago Poles could observe 3 May freely, while their relatives in partitioned Poland could not. The same is broadly true of London, Paris, Toronto, and (later) Buenos Aires. The diaspora kept the date alive when the homeland could not. This historical role is part of what the 2002 Day of the Polish Diaspora law on 2 May was acknowledging — fifteen years before that law was passed, diaspora communities had already been doing the formal work of national memory for over a century.
After Polish independence was restored in 1918, the Second Republic immediately reinstated 3 May as a national holiday. The first official observance under restored sovereignty took place on 3 May 1919. From 1919 to 1939, Constitution Day was the Polish national day in everything but legal name — schools held assemblies, military parades took place in every garrison town, and Marian devotions filled churches.
After the war, under the Polish People's Republic (PRL), the communist authorities replaced 3 May with 1 May in the official calendar. 3 May was simply removed from the list of public holidays. Observances were held quietly by the Catholic Church and in private — Masses were celebrated at the Jasna Góra monastery in Częstochowa, attended by very large gatherings across the 1980s despite official discouragement. The PRL period also produced the wave of emigration that built much of today's Western diaspora — a story we cover separately in our piece on the impact of martial law on Polish emigrants.
In April 1990, the post-communist Polish parliament restored 3 May as a national holiday. The first restored observance, in May 1990, was substantial — a state ceremony at the Royal Castle, a Mass at St. John's Cathedral, military parades in every major city. The holiday has been observed continuously since.
Why is the Feast of Mary, Queen of Poland on the same day?
The doubling of 3 May as both Constitution Day and the Feast of the Blessed Virgin Mary, Queen of Poland is a deliberate ecclesiastical choice by the Polish bishops, made in 1920.
The Marian patronage of Poland is much older than the feast date. It dates formally to 1656, when King Jan Kazimierz made the Lwów Vows in the cathedral of Lwów after Poland's near-defeat in the Swedish-Polish wars (the "Deluge"). In the Vows, the king dedicated the Polish-Lithuanian Commonwealth to the protection of the Virgin Mary and proclaimed her "Queen of the Polish Crown." The dedication has remained constant in Polish Catholic practice for nearly four centuries.
What the bishops did in 1920 was to attach a specific feast date to this dedication, and to choose 3 May for that purpose. The choice was deliberate — they wanted to bind the religious memory of Polish Marian devotion to the civic memory of the Constitution. It was a way of putting the Catholic and the constitutional traditions in the same room.
For Polish Catholics — which is most Poles — this means 3 May is a doubly weighty day. Mass attendance on 3 May is significantly higher than on a normal Sunday. The Marian devotion also gives the day a religious texture even for Poles who would not have attended a purely civic observance. The Częstochowa pilgrimage to the icon of the Black Madonna at the Jasna Góra monastery — which dates to the 14th century — picks up substantial numbers around 3 May.
For non-Catholic Poles, and for Polish-heritage families abroad from Jewish, Protestant, or secular traditions, the religious doubling is sometimes more complicated. The civic meaning of the Constitution is universally Polish; the Marian framing is specifically Catholic. This is one of the points where the question of "what does Polishness mean" gets a bit more textured — and where the diaspora's relationship with the holiday tends to be more selective.
What does Constitution Day look like today?
3 May is one of Poland's most fully observed national holidays. The day's structure is consistent across most cities, and recognising the rhythm helps if you're either visiting Poland or organising a diaspora observance.
The morning. The day typically begins with a state ceremony at the Tomb of the Unknown Soldier in Plac Piłsudskiego in Warsaw. The President of the Republic lays a wreath. Senior military officers attend in dress uniform. Speeches are short — Polish state ceremony is usually more visual than rhetorical. The ceremony is broadcast live on Polish television.
The Mass. Pontifical High Mass at St. John's Archcathedral in Warsaw's Old Town, the primatial church of Poland, is celebrated by the Primate or by the Archbishop of Warsaw. Senior state officials attend. The Mass is, by custom, partly in Latin — using older liturgical settings that resonate with the Constitution's 18th-century context. Similar Masses take place at the cathedrals in every major Polish diocese.
Parades. Every major Polish city — Warsaw, Kraków, Gdańsk, Poznań, Wrocław, and many smaller towns — holds a Constitution Day parade. The Warsaw parade moves through the Royal Route. The Kraków parade moves from Wawel Cathedral to the Main Square, along the same route used for centuries. Military, civic, scholastic, and religious groups participate — Polish military involvement in patriotic observances is a longer subject covered in our piece on Armed Forces Day in Poland.
Mazurek Dąbrowskiego. The Polish national anthem is sung — at the state ceremony, at every parade, in every Mass, by school children at assembly. The anthem itself ("Jeszcze Polska nie zginęła" / "Poland has not yet perished") was written in 1797 by a Polish soldier in Italy, two years after the Third Partition, when the Polish state had just ceased to exist. The line "as long as we live" is, on 3 May, particularly heavy.
Family time. 3 May is typically a family day for Polish households. Sunday lunch on a national-holiday scale — pierogi, sour cucumber soup, schabowy or pieczeń, often kompot or wine. Many families travel to spend the day with grandparents.
For most Poles, 3 May feels weightier than 11 November (Independence Day) or 1 May (Labor Day). It is, perhaps, the day on which the country most fully observes itself as a country.
How do Polish communities abroad observe 3 May?
For the Polish diaspora, 3 May is the central patriotic date of the calendar year, and observances tend to be substantial.
The Chicago Polish Constitution Day Parade, held annually since 1892 (with brief wartime interruptions), is the largest Polish ethnic parade in North America. The parade route runs through Chicago's downtown, drawing tens of thousands of participants — Polish-American organisations, fraternal societies, Polish-language schools, scout troops, dance ensembles, military veterans' groups, parishes, and city dignitaries. Chicago has the largest Polish-descent population outside Poland itself, and the parade is the year's central institutional event of that community.
London hosts a major Polish 3 May ceremony at Westminster Cathedral, often attended by the Polish Ambassador and the leadership of the Polish Government-in-Exile (which formally dissolved in 1990 but maintains commemorative associations). Northolt Aerodrome — long associated with Polish RAF squadrons in WWII — hosts a separate military observance.
Toronto, Buffalo, New York, Detroit, and other North American cities with substantial Polish populations hold parades and Masses. The character is similar everywhere — formal flag-raisings, brief speeches, often a community lunch or reception afterwards.
Curitiba, Brazil — the centre of the largest Polish community in South America — observes 3 May with a Mass at the Polish parish, a community gathering, and often a folk dance presentation. The Curitiba Polish community traces back to the 1870s and 1880s agricultural emigration from southern Poland.
Melbourne and Sydney hold smaller but well-organised Polish 3 May events, generally clustered around Polish parishes and community centres.
The diaspora 3 May parade is, for many fourth- and fifth-generation Polish Americans, Polish Canadians, and Polish Australians, the single most continuous point of annual contact with their Polish heritage. Children learn the Polish anthem for it. Grandfathers pull out medals from regiments that haven't existed in eighty years. Polish Saturday schools spend weeks rehearsing. The day has the feel of a small national festival, conducted in a country that is not Poland, by people who in many cases have never been there.
If you are reconnecting with Polish heritage and based in the diaspora, the 3 May parade in your city — if there is one — is the single most welcoming event of the Polish-heritage calendar. Showing up with no prior connection is normal. Bringing a child, a partner, or a curious friend is expected. The community will assume that anyone present has at least some Polish connection, and very rarely interrogates the depth of that connection.
Why the date still matters
The Constitution of 3 May is one of those rare political documents that matters more for what it represented than for what it did. It was in force for fourteen months. It was not a successful constitutional reform, in the sense that it did not save the state it was written for. By any practical measure, it failed.
And yet — for 234 years, Poles have continued to mark its anniversary, often at substantial personal risk during the periods when doing so was banned. The reason is not historical sentimentality. It is that the Constitution of 3 May was a clear, public attempt to write down what the Polish political community thought it was — a sovereign nation, deserving of self-governance, capable of constitutional order on the modern European model. The fact that this attempt was crushed by external powers does not negate the attempt itself. If anything, the crushing makes the attempt more important, because it shifts the meaning of the date from "a successful constitutional reform" to "a sovereign nation refusing to accept that its sovereignty has ended."
This is, in the end, what 3 May is about. Not the specific provisions of the Ustawa Rządowa — most Poles cannot recite them, and they were never fully implemented — but the underlying claim: that Poland exists as a political community whether or not anyone outside Poland says so, and that the work of constituting that community in writing is a thing Poles have always been willing to do.
For the diaspora, this lands a bit differently. A fourth-generation Polish-American, attending the Chicago parade with her grandfather, is not really commemorating the constitutional provisions of 1791. She is participating in a chain of remembrance that links 1791 in Warsaw to 1892 in Chicago to 2026 in some midwestern park. The chain is the point.
The 3 May observance is a quiet, formal way of saying: we are still here. The Polish state has been extinguished and restored. The Polish nation, as a community of memory, has carried itself through everything that happened in between. The Constitution of 3 May is the document around which that community organises its memory of itself — and the date is the moment, each year, when that memory is brought into the present.
Key takeaways:
- The Constitution of 3 May 1791 was the second written national constitution in the world (after the United States) and the first in Europe — passed during the Four-Year Sejm in a single dramatic session at the Royal Castle in Warsaw.
- It was in force for fourteen months before being suspended after Russian military intervention in 1792, triggered by the Targowica Confederation of conservative Polish magnates.
- For 123 years between the partitions and 1918, observing the Constitution was illegal or suspicious in most of the Polish lands — yet the date was preserved in private and abroad.
- The Catholic Church places the Feast of Mary, Queen of Poland on the same day, by deliberate choice in 1920, to bind the religious and civic memory of 3 May together.
- Constitution Day was restored as a Polish national holiday in April 1990 and has been observed continuously since.
- Diaspora observances — particularly Chicago's parade since 1892 — kept the date alive when Poland itself could not.
A quiet thread between 1791 and now
The Constitution of 3 May extended civic membership beyond a narrow nobility — and that instinct, of defining the nation by continuity of belonging, runs through Polish history into the present. If your family was part of that longer story, our short heritage assessment is a diagnostic look at what your documents actually show.
Take the heritage assessmentFrequently asked questions
What exactly does the Constitution of 3 May say?
The Constitution is structured in eleven articles, covering the state religion (Catholicism, with tolerance for others), the political rights of the nobility and townspeople, the status of peasants, the structure of the Sejm, the executive government (the Straż Praw — Guardians of the Laws), the judiciary, and the mechanics of the hereditary monarchy. Key reforms included the abolition of the liberum veto, the establishment of majority rule in the Sejm, the creation of a hereditary monarchy in the House of Saxony, and the extension of political rights to townspeople. Peasants were placed "under the protection of the law" — vague but unprecedented language for the time. The original is held at the Central Archives of Historical Records in Warsaw.
Was the Constitution really in force for only fourteen months?
Yes. Adopted on 3 May 1791 and formally suspended in July 1792, when King Stanisław August acceded to the Targowica Confederation — a group of conservative Polish magnates who had invited Russian military intervention to overturn the reforms. During those fourteen months, the new institutions did begin to operate: the Straż Praw met, the reformed Sejm functioned, and Polish state finances and the military were reorganised. The brevity of the implementation period is part of why the Constitution carries more symbolic than legal weight today.
What happened to the people who wrote the Constitution?
The fates varied. King Stanisław August Poniatowski was forced to abdicate after the Third Partition in 1795 and died in St. Petersburg in 1798. Hugo Kołłątaj, the bishop-reformer, was imprisoned in Austrian custody for eight years after the 1794 Kościuszko Uprising, then returned to scholarly and educational work. Ignacy Potocki, the reformer and diplomat, died in 1809 while seeking support for Polish statehood from Napoleon. Tadeusz Kościuszko, whose 1794 uprising attempted to defend the Constitution militarily, was wounded, imprisoned by the Russians, released, and spent the rest of his life in exile in Switzerland and the United States.
Is 3 May a public holiday in Poland?
Yes — Święto Konstytucji 3 Maja (Constitution Day) is a statutory public holiday. Shops, offices, banks, and public institutions are closed. It has been a public holiday continuously since April 1990, when the post-communist Polish parliament restored it. It was previously a public holiday during the interwar Second Republic (1919–1939). Under the PRL (1945–1989), it was officially abolished.
Why is the Feast of Mary, Queen of Poland also on 3 May?
The feast was deliberately placed on 3 May by the Polish Episcopate in 1920, on the occasion of establishing it as a liturgical feast for Poland. The bishops petitioned the Vatican specifically for 3 May, citing the connection between the Marian patronage of Poland (dating to King Jan Kazimierz's Lwów Vows of 1656) and the Constitution. In 1962, Pope John XXIII formally declared Mary, Queen of Poland the principal patron of the country.
What does "Targowica" mean, and why is it still an insult?
Targowica (tar-go-VEET-sa) was the town in what is now Ukraine where, in 1792, a group of Polish conservative magnates — opposed to the Constitution of 3 May — signed a confederation declaration that invited Russian military intervention in Poland. The act is considered the decisive trigger for the Polish–Russian War of 1792, the Second Partition of 1793, and ultimately the disappearance of the Polish state in 1795. In modern Polish, "Targowica" and "Targowiczanin" (a member of the Targowica Confederation) are standard synonyms for national betrayal — among the heaviest accusations possible in Polish political discourse.
Do Polish diaspora communities really hold Constitution Day parades?
Extensively. The Chicago Polish Constitution Day Parade, held since 1892, is by long-standing reputation the largest Polish ethnic parade in the United States. Other major diaspora observances include London (Westminster Cathedral and Northolt), Toronto, Buffalo, New York, Detroit, Melbourne, and Curitiba. For fourth- and fifth-generation diaspora Poles, the 3 May parade may be the single most continuous point of annual Polish identity. Diaspora Constitution Day observances are open to all and typically welcoming of newcomers re-engaging with Polish heritage.
