In 2018, a researcher from Kraków helping a distant relative from Brazil trace Polish ancestors ran into a deceptively simple problem: the family remembered the name of their home village — Żuromin — and a surname. But when she opened Poland's state archive, it turned out the registers for that village, for the relevant period, weren't held in Poland at all, but in the holdings of a consistory which, after the nineteenth-century administrative reform, belonged to the Płock Governorate of the Russian Empire — and the entry itself was written in Russian, even though the parish remained Catholic. Polish genealogy almost always starts with one fact that surprises beginners: between 1795 and 1918, Poland did not exist as a state on the map at all — and this shapes literally everything about archival research.
As a result of the three partitions of the Polish–Lithuanian Commonwealth carried out by Russia, Austria and Prussia in 1772, 1793 and 1795, Polish lands were entirely absorbed into three empires and remained divided until independence was restored in 1918. The Russian portion ('Vistula Land', later reorganised into ten governorates) was administered under Russian law and over time shifted to Russian-language record-keeping; the Austrian portion ('Galicia') was administered from Vienna and retained a more liberal regime of local self-government; the Prussian portion was subject to German administrative order and the German language of record-keeping. Because the three empires kept documentation under different rules and in different languages, finding a record about an ancestor means above all establishing which of the three zones the family lived in at the relevant time — and that zone may not correspond to the borders of modern-day Poland.
The principal tool for orienting yourself within Polish archival holdings is the PRADZIAD database, maintained by the State Archives of Poland: it doesn't contain the records themselves, but precisely indicates which parish registers, for which parish and which years, have survived and in which archive they are held. Once you have the fonds number and archive name from PRADZIAD, you move on to the Szukajwarchiwach.gov.pl portal, where a substantial share of holdings has already been digitised and is viewable without registration. The Central Archives of Historical Records (AGAD) in Warsaw, which holds documents from before the nineteenth-century reforms along with materials for lands belonging to the Russian and partly the Austrian zones, remains a separate institution, and part of its holdings aren't described in PRADZIAD at all — for documents predating the nineteenth century, it's worth contacting AGAD directly.
The overwhelming majority of ethnic Poles were Catholic, and parish registers were kept in Latin until the mid-nineteenth century, after which — depending on the zone — they continued in Russian, German or Polish. Eastern parishes, particularly in what is now western Ukraine and Belarus, might be Greek Catholic (Uniate) or Orthodox, in which case the registers are held in the fonds of the relevant consistory rather than a Catholic diocese. The Jewish population, which made up a significant share of pre-war Poland's residents, was recorded separately by rabbis, in entries that, after 1826 in the Russian zone, were duplicated by civil registers — and these records are today consolidated into the specialised Jewish Records Indexing-Poland (JRI-Poland) index, separate from the general Polish archival inventories.
The same person's name could be recorded differently depending on the zone and language of record-keeping: Stanisław in German documents became Stanislaus, in Russian ones Станислав, while women's surnames in the Polish tradition often took a special ending (Kowalska — the daughter or wife of Kowalski), easily mistaken for a separate surname if you don't know this grammatical rule.
Before the early nineteenth century, the recording of births, marriages and deaths on Polish lands was handled exclusively by churches — each faith kept its own books, and the state had no part in them. This changed in 1808, when the short-lived Duchy of Warsaw, created by Napoleon out of part of the Polish lands, introduced the French Civil Code, obliging clergy to keep registers in a single secular format laid down by the state rather than by church tradition. This format — with separate sections for births, marriages and deaths and standardised columns — outlived the duchy itself and survived, with amendments, across all three partition zones throughout the nineteenth century, which is why an 1820 register from the Russian, Austrian or Prussian zone is structurally far more alike than one might expect from three different empires.
Paging through scanned parish registers one by one is a task justified only once the exact date of an event is already known. For every other case, there is Geneteka (geneteka.genealodzy.pl) — a free database that the Polish Genealogical Society has maintained since 2011, built by volunteers who index names, dates and places from parish registers. The database covers millions of records across all three historical zones and lets you search by surname and region without needing to know the specific archival fonds — and only after locating an entry in the index do you move on to viewing the scan itself via Szukajwarchiwach or a particular archive's website. For most beginning researchers, Geneteka, not archival inventories, should be the first step of a search.
Until the late eighteenth century, a substantial part of the rural population of Polish lands had no surname at all — a person was known by a given name and patronymic, sometimes with a nickname based on occupation or place of residence, and that nickname could change from one generation to the next. The fixing of surnames as a mandatory legal element happened at different times in different zones: in Austrian Galicia, by an 1787 decree; in the Prussian zone, somewhat earlier; in the Russian zone, the process stretched across the whole nineteenth century and concluded latest of all. For the Jewish population of the Russian Empire, surnames became mandatory only under decrees of 1821–1826, and the surname in such cases frequently derived from the name of the home shtetl, the head of household's occupation, or was simply assigned by an official at registration — which explains why two unrelated Jewish families from the same shtetl could end up sharing the same surname without any actual kinship.
For Greater Poland — the historical region centred on Poznań, which belonged to the Prussian partition zone — there's a dedicated project that illustrates just how effective volunteer effort can be: the Poznań Project indexes marriage records from 1800 to 1899 across the entire region and offers free searches by the surnames of both parties to a marriage. Begun in the 1990s by German and Polish genealogical communities, the project today covers virtually every parish in the region and often makes it possible to find a record faster than through general portals like Geneteka, precisely because it is focused on one region and one type of document.
The eastern lands of pre-war Poland — the so-called Kresy, encompassing a substantial part of what is now western Ukraine, Belarus and Lithuania — were part of the Polish state until 1939, after which they were absorbed into the USSR following the Second World War. For descendants of people from these lands, this means a home village today is physically located outside Poland: its registers may be held in a Ukrainian, Belarusian or Lithuanian state archive rather than a Polish one, even if the parish was Catholic and kept its records in Polish. This is one of the most common sources of confusion at the start of a search — an enthusiast spends months sending requests to Polish archives before realising that the fonds they need sits in the Lviv or Hrodna regional archive.

Polish genealogical research is complicated precisely because the country in its modern borders is a relatively recent phenomenon, and the archival system of the past two centuries was built by three different empires that never coordinated their record-keeping rules with one another. But that's exactly why a systematic understanding of the partition zones and the specialised databases turns a search from wandering between archives into a coherent route.
