Names of Poland: Polska, Polonia and Lechia
Poland is known by several names, depending on the language, the time period and whether you are reading an official document, an old map, or a church inscription. In English it’s Poland. In Polish it’s Polska. In Latin you’ll often see Polonia. In older cultural references you may come across Lechia. And in formal state language you’ll meet Rzeczpospolita.
The language and date of a document help you interpret these names. A Latin country name on a parish entry may describe the same place that a British certificate calls Poland.
Names used for Poland
- Polska - the native Polish name for Poland.
- Poland - the English name, built around “the Poles” as a people.
- Polonia - the Latin name, common in older writing, churches and inscriptions.
- Lechia - an old poetic/historic name linked to Lech/Lechites in tradition.
- Rzeczpospolita (Polska) - “Commonwealth/Republic (of Poland)”, used in formal state titles.
Polska: Poland’s name in Polish
Polska is what Polish speakers call their country. You’ll see it everywhere in modern Polish life: in newspapers, on official websites, on road signs, and in everyday speech.
The full official form, Rzeczpospolita Polska (“Republic of Poland”), appears on passports, state documents and government forms.
Poland: the English name
Poland is an exonym: a name for a country used by outsiders rather than by its own people. English built it from the name of the people, the Poles, and the word land. It is the form used in British, American and Canadian certificates and census returns for country of birth or nationality.
Polonia: the Latin name that appears in churches and older texts
Polonia is the Latin form. Latin was the language of the Church, scholarship and formal inscriptions for centuries, so Polonia appears in:
- church records and memorial inscriptions
- academic writing
- mottos, medals and emblems
- diaspora names (many Polish communities abroad use “Polonia” in organisation names)
Polonia on a headstone or in a parish register means the writer used Latin, not that a different country is meant.
Lechia in literature and historical tradition
Lechia is an old name linked to the legend of Lech, the mythical forefather of the Poles. It appears in:
- poetry and patriotic writing
- cultural references and symbolic language
- some historic chronicles and discussions of early Slavic identity
It is a literary name. You are unlikely to find it in 19th- or 20th-century civil or parish records.
Rzeczpospolita: “Commonwealth/Republic” in official language
Rzeczpospolita is the Polish rendering of the Latin res publica. It is translated as Commonwealth or Republic, depending on the period, and appears in state names such as:
- Rzeczpospolita Polska (modern state name)
- Rzeczpospolita Obojga Narodów (Commonwealth of the Two Nations), the Polish name for the Polish-Lithuanian Commonwealth
Country names in family records
The name used for Poland in a record depends on who wrote it and in which language, not on how the family described themselves.
1) Latin in church contexts
Baptisms, marriages and burials may use Latin-style forms, especially in older registers. That can include Polonia or Latinised versions of place names and first names.
2) English forms in UK records
British records usually say Poland, but an informant may have given Russia, Austria, Germany or Prussia for someone born before 1918, depending on who governed the birthplace at the time.
3) Historical labels tied to administration
Even when a family considered themselves Polish, the administration governing the birthplace may have been different at certain points in history. That can influence:
- the language used in records
- where the records are stored today
- how a location is spelled
Searching indexes: do not rely on a single country label. Use town names, surname variants, religion, and family networks to identify the locality.
