Kashubians
West Slavic ethnic group
The Kashubians (Kashubian: Kaszëbi; Polish: Kaszubi; German: Kaschuben), also known as Cassubians or Kashubs, are a West Slavic ethnic group native to the historical region of Pomerania, including its eastern part called Pomerelia, in north-central Poland. Their settlement area is referred to as Kashubia. They speak the Kashubian language, which is classified as a separate language closely related to Polish.
The Kashubs are closely related to the Poles and sometimes classified as their subgroup. Moreover, the vast majority of Kashubians declare themselves as Poles and many of them have a Polish-Kashubian identity. The Kashubs are grouped with the Slovincians as Pomeranians. Similarly, the Slovincian (now extinct) and Kashubian languages are grouped as Pomeranian languages, with Slovincian (also known as Łeba Kashubian) either a distinct language closely related to Kashubian, or a Kashubian dialect.
Modern Kashubia
Among larger cities, Gdynia (Gdiniô) contains the largest proportion of people declaring Kashubian origin. However, the biggest city of the Kashubia region is Gdańsk (Gduńsk), the capital of the Pomeranian Voivodeship. Between 80.3% and 93.9% of the people in towns such as Linia, Sierakowice, Szemud, Kartuzy, Chmielno, Żukowo, etc.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Kashubians”, the useful work is to connect “west Slavic ethnic group” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q147239. The Library of Congress control number is sh85071707. None of the 1 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
