The Kashubians (Kashubian: Kaszëbi; Polish: Kaszubi; German: Kaschuben), also known as Cassubians or Kashubs, are a Lechitic (West Slavic) ethnic group native to the historical region of Eastern Pomerania 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. 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.
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. are of Kashubian descent.
The traditional occupations of the Kashubs have been agriculture and fishing. These have been joined by the service and hospitality industries, as well as agrotourism. The main organization that maintains the Kashubian identity is the Kashubian-Pomeranian Association. The recently formed "Odroda" is also dedicated to the renewal of Kashubian culture.
The traditional capital has been disputed for a long time and includes Kartuzy (Kartuzë) among the seven contenders. The biggest cities claiming to be the capital are: Gdańsk (Gduńsk), Wejherowo (Wejrowò), and Bytów (Bëtowò).
The total number of Kashubians (Pomeranians) varies depending on one's definition. A common estimate is that over 500,000 people in Poland are of the Kashubian ethnicity, the estimates range from ca. 500,000 to ca. 570,000. In the Polish census of 2002, only 5,100 people declared Kashubian national identity, although 52,655 declared Kashubian as their everyday language. Most Kashubs declare Polish national identity and Kashubian ethnicity, and are considered both Polish and Kashubian. On the 2002 census there was no option to declare one national identity and a different ethnicity, or more than one ethnicity. On the 2011 census, the number of persons declaring "Kashubian" as their only ethnicity was 16,000, and 233,000 including those who declared Kashubian as first or second ethnicity (together with Polish). In that census, over 108,000 people declared everyday use of Kashubian language. The number of people who can speak at least some Kashubian is higher, around 366,000.

As of 1890, linguist Stefan Ramułt estimated the number of Kashubs (including Slovincians) in Pomerelia as 174,831. He also estimated that at that time there were over 90,000 Kashubs in the United States, around 25,000 in Canada,15,000 in Brazil and 25,000 elsewhere in the world. In total 330,000.
Kashubs are a Western Slavic people living on the shores of the Baltic Sea. Kashubs have their own unique language and traditions, having lived somewhat isolated for centuries from the common Polish population.
Until the end of the 12th century, the vast majority of inhabitants of Pomerania (Hither, Farther and Eastern) were Slavic-speakers, but the province was quite sparsely populated, with large areas covered by forests and waste lands. During the 13th century, the German Ostsiedlung began in this region. Slavic dukes of Pomerania such as Barnim I (1220–1278) – despite calling themselves dux Slavorum et Cassubie – contributed a lot to the change of ethnic structure by promoting German immigration and granting land to German nobles, monks and clergy. The Slavic ruling dynasty itself started intermarrying with German princesses and became culturally Germanized over time. Wendish commoners became alienated in their own land, their culture replaced by that of newcomers. All of this led to Germanization of most of Slavic Pomeranians and the gradual death of their Slavic language, with the general direction of assimilation and language shift from west to east.
Johannes Bugenhagen wrote that at the beginning of the 16th century the German-Slavic language border was near Koszalin. During the 17th century, the border between areas with mostly German-speaking and mostly Slavic-speaking populations ran more or less along the present-day border between West Pomeranian and Pomeranian Voivodeships.
In year 1612, cartographer Eilhard Lubinus – while working on his map of Pomerania – travelled from the direction of Pollnow towards Treblin on his way to Danzig. While staying in the manor house of Stanislaus Stenzel von Puttkamer in Treblin, he noted in his diary: "we have entered Slavic-inhabited lands, which has surprised us a lot." Later, while returning from Gdańsk to Stettin, Lubinus slept over in Wielka Wieś near Stolp, and noted: "in the whole village, we cannot find even one German-speaker" (which caused communication problems).
Over a century later, in 1772–1778, the area was visited by Johann Bernoulli. He noted that villages owned by Otto Christoph von Podewils – such as Dochow, Zipkow and Warbelin – were inhabited entirely by Slavic-speakers. He also noted that local priests and nobles were making great efforts to weed out Slavic language and turn their subjects into Germans.

Karl Andree, Polen: in geographischer, geschichtlicher und culturhistorischer Hinsicht (Leipzig 1831), gives the total population of West Prussia as 700,000 – including 50% Poles (350,000), 47% Germans (330,000) and 3% Jews (20,000). Kashubians are included with Poles, while Mennonites with Germans.
Modern estimates of Kashubian population in West Prussia in the early 19th century, by county, are given by Leszek Belzyt and Jan Mordawski:
|County (Kreis)||Total population||Kashubians and Poles||Percent|
|Chojnice (Konitz) without Tuchola||23,000||15,525||67.5%|
|Gdańsk Highlands (Danziger Höhe)||27,000||9,450||35.0%|
|Total in Eastern Kashubia:||170,125||103,400||60.8%|
According to Georg Hassel, there were 65,000 Slavic-speakers in the whole Provinz Pommern in 1817–1819. Modern estimates for just eastern parts of Pommern (Western Kashubia) in early 1800s range between 40,000 (Leszek Belzyt) and 25,000 (Jan Mordawski, Zygmunt Szultka). The number declined to between 35,000 and 23,000 (Zygmunt Szultka, Leszek Belzyt) in years 1827–1831. In 1850-1860s there were an estimated 23,000 to 17,000 Slavic-speakers left in Pommern, down to 15,000 in 1892 according to Stefan Ramułt. The number was declining due to Germanisation. The bulk of Slavic population in 19th century Pommern was concentrated in its easternmost counties: especially Bytów (Bütow), Lębork (Lauenburg) and Słupsk (Stolp).
Reichstag elections (1867–1912)
In all constituencies with significant Catholic Kashubian population (Neustadt in Westpr.-Putzig-Karthaus; Berent-Preußisch Stargard-Dirschau; and Konitz-Tuchel), all Reichstag elections in 1867–1912 were won by the Polish Party (Polnische Fraktion, later Polenpartei).
Kashubs descend from the Slavic Pomeranian tribes, who had settled between the Oder and Vistula Rivers after the Migration Period, and were at various times Polish and Danish vassals. While most Slavic Pomeranians were assimilated during the medieval German settlement of Pomerania (Ostsiedlung), especially in Eastern Pomerania (Pomerelia) some kept and developed their customs and became known as Kashubians.
The tenth century far-traveled Arab writer Al-Masudi – who had great interest in non-Muslim peoples, including the various Slavs of Eastern Europe – mentions a people which he calls Kuhsabin, who were probably Kashubians. The oldest known unambiguous mention of "Kashubia" dates from 19 March 1238 – Pope Gregory IX wrote about Bogislaw I as dux Cassubie – the Duke of Kashubia. The old one dates from the 13th century (a seal of Barnim I from the House of Pomerania, Duke of Pomerania-Stettin). The Dukes of Pomerania hence used "Duke of (the) Kashubia(ns)" in their titles, passing it to the Swedish Crown who succeeded in Swedish Pomerania when the House of Pomerania became extinct.
Administrative history of Kashubia
The westernmost (Slovincian) parts of Kashubia, located in the medieval Lands of Schlawe and Stolp and Lauenburg and Bütow Land, were integrated into the Duchy of Pomerania in 1317 and 1455, respectively, and remained with its successors (Brandenburgian Pomerania and Prussian Pomerania) until 1945, when the area became Polish. The bulk of Kashubia since the 12th century was within the medieval Pomerelian duchies, since 1308 in the Monastic state of the Teutonic Knights, since 1466 within Royal Prussia, an autonomous territory of the Polish Crown, since 1772 within West Prussia, a Prussian province, since 1920 within the Polish Corridor of the Second Polish Republic, since 1939 within the Reichsgau Danzig-West Prussia of Nazi Germany, and since 1945 within the People's Republic of Poland, and after within the Third Polish Republic.
German and Polish impact
German Ostsiedlung in Kashubia was initiated by the Pomeranian dukes and focussed on the towns, whereas much of the countryside remained Kashubian. An exception was the German settled Vistula delta (Vistula Germans), the coastal regions, and the Vistula valley. Following the centuries of interaction between local German and Kashubian population, Aleksander Hilferding (1862) and Alfons Parczewski (1896) confirmed a progressive language shift in the Kashubian population from their Slavonic vernacular to the local German dialect (Low German Ostpommersch, Low German Low Prussian, or High German).
On the other hand, Pomerelia since the Middle Ages was assigned to the Kuyavian Diocese of Leslau and thus retained Polish as the church language. Only the Slovincians in 1534 adopted Lutheranism after the Protestant Reformation had reached the Duchy of Pomerania, while the Kashubes in Pomerelia remained Roman Catholic. The Prussian parliament (Landtag) in Königsberg changed the official church language from Polish to German in 1843. But this decision was soon repealed.
In the 19th century the Kashubian activist Florian Ceynowa undertook efforts to identify the Kashubian language, and its culture and traditions. Although his efforts did not appeal to locals at the time, Kaszubian activists in the present day have claimed that Ceynowa awakened Kashubian self-identity, thereby opposing both Germanisation and Prussian authority, and Polish nobility and clergy. He believed in a separate Kashubian identity and strove for a Russian-led pan-Slavic federacy, He considered Poles "born brothers". Ceynowa was a radical who attempted to take the Prussian garrison in Preussisch Stargard (Starogard Gdański) during 1846 (see Greater Poland uprising), but the operation failed when his 100 combatants, armed only with scythes, decided to abandon the site before the attack was carried out. Although some later Kashubian activists tried to push for a separate identity, they further based their ideas on a misrepresented reading of the journalist and activist Hieronim Derdowski: "There is no Cassubia without Polonia, and no Poland without Cassubia" (Nie ma Kaszeb bez Polonii a bez Kaszeb Polsci"). Further stanzas of Derdowski's tribute also point to the fact that Kaszubs were Poles and could not survive without. The Society of Young Kashubians (Towarzystwo Młodokaszubskie) has decided to follow in this way, and while they sought to create a strong Kashubian identity, at the same time they regarded the Kashubians as "One branch, of many, of the great Polish nation".
The leader of the movement was Aleksander Majkowski, a doctor educated in Chełmno with the Society of Educational Help in Chełmno. In 1912 he founded the Society of Young Kashubians and started the newspaper Gryf. Kashubs voted for Polish lists in elections, which strengthened the representation of Poles in the Pomerania region. Between 1855 and 1900, about 100,000 Kashubs emigrated to the United States, Canada, Brazil, New Zealand, and Australia in the so-called Kashubian diaspora, largely for economic reasons. In 1899 the scholar Stefan Ramult named Winona, Minnesota the "Kashubian Capital of America" on account of the Kashubian community's size within the city and its activity. Due to their Catholic faith, the Kashubians became subject to Prussia's Kulturkampf between 1871 and 1878. The Kashubians faced Germanification efforts, including those by evangelical Lutheran clergy. These efforts were successful in Lauenburg (Lębork) and Leba (Łeba), where the local population used the Gothic alphabet. While resenting the disrespect shown by some Prussian officials and Junkers, Kashubians lived in peaceful coexistence with the local German population until World War II, although during the interbellum, the Kashubian ties to Poland were either overemphasized or neglected by Polish and German authors, respectively, in arguments regarding the Polish Corridor.
During the Second World War, Kashubs were considered by the Nazis as being either of "German stock" or "extraction", or "inclined toward Germanness" and "capable of Germanisation", and thus classified third category of Deutsche Volksliste (German ethnic classification list) if ties to the Polish nation could be dissolved. However, Kashubians who were suspected to support the Polish cause, particularly those with higher education, were arrested and executed, the main place of executions being Piaśnica (Gross Plassnitz), where 12,000 were executed. The German administrator of the area Albert Forster considered Kashubians of "low value" and didn't support any attempts to create Kashubian nationality. Some Kashubians organized anti-Nazi resistance groups, Gryf Kaszubski (later Gryf Pomorski), and the exiled Zwiazek Pomorski in Great Britain.
When integrated into Poland, those envisioning Kashubian autonomy faced a Communist regime striving for ethnic homogeneity and presenting Kashubian culture as merely folklore. Kashubians were sent to Silesian mines, where they met Silesians facing similar problems. Lech Bądkowski from the Kashubian opposition became the first spokesperson of Solidarność.
In 2011 Population Census about 108,100 people declared Kashubian as their language.
The classification of Kashubian as a language or dialect has been controversial. From a diachronic point of view of historical linguistics, Kashubian, like Slovincian, Polabian and Polish, is a Lechitic West Slavic language, while from a synchronic point of view it is a group of Polish dialects. Given the past nationalist interests of Germans and Poles in Kashubia, Barbour and Carmichel state: "As is always the case with the division of a dialect continuum into separate languages, there is scope here for manipulation."
A "standard" Kashubian language does not exist despite attempts to create one, rather a variety of dialects are spoken that differ significantly from each other. The vocabulary is influenced by both German and Polish.
There are other traditional Slavic ethnic groups inhabiting Pomerania, including the Kociewiacy, Borowiacy and Krajniacy. These dialects tend to fall between Kashubian and the Polish dialects of Greater Poland and Mazovia, with Krajniak dialect indeed heavily influenced by Kashubian, while Borowiak and Kociewiak dialects much more closer to Greater Polish and Mazovian. No obvious Kashubian substrate or any other influence is visible in Kociewiak dialect. This indicates that they are not only descendants of Pomeranians, but also of settlers who arrived in Pomerania from Greater Poland and Masovia during the Middle Ages, from the 10th century onwards.
In the 16th and 17th century Michael Brüggemann (also known as Pontanus or Michał Mostnik), Simon Krofey (Szimon Krofej) and J.M. Sporgius introduced Kashubian into the Lutheran Church. Krofey, pastor in Bütow (Bytow), published a religious song book in 1586, written in Polish but also containing some Kashubian words. Brüggemann, pastor in Schmolsin, published a Polish translation of some works of Martin Luther (catechism) and biblical texts, also containing Kashubian elements. Other biblical texts were published in 1700 by Sporgius, pastor in Schmolsin. His Schmolsiner Perikopen, most of which is written in the same Polish-Kashubian style as Krofey's and Brüggemann's books, also contain small passages ("6th Sunday after Epiphany") written in pure Kashubian. Scientific interest in the Kashubian language was sparked by Christoph Mrongovius (publications in 1823, 1828), Florian Ceynowa and the Russian linguist Aleksander Hilferding (1859, 1862), later followed by Leon Biskupski (1883, 1891), Gotthelf Bronisch (1896, 1898), Jooseppi Julius Mikkola (1897), Kazimierz Nitsch (1903). Important works are S. Ramult's, Słownik jezyka pomorskiego, czyli kaszubskiego, 1893, and Friedrich Lorentz, Slovinzische Grammatik, 1903, Slovinzische Texte, 1905, and Slovinzisches Wörterbuch, 1908. Zdzisław Stieber was involved in producing linguistic atlases of Kashubian (1964–78).
The first activist of the Kashubian national movement was Florian Ceynowa. Among his accomplishments, he documented the Kashubian alphabet and grammar by 1879 and published a collection of ethnographic-historic stories of the life of the Kashubians (Skórb kaszébsko-slovjnckjé mòvé, 1866–1868). Another early writer in Kashubian was Hieronim Derdowski. The Young Kashubian movement followed, led by author Aleksander Majkowski, who wrote for the paper Zrzësz Kaszëbskô as part of the "Zrzëszincë" group. The group would contribute significantly to the development of the Kashubian literary language. Another important writer in Kashubian was Bernard Sychta (1907–1982).
Similarly to the traditions in other parts of Central and Eastern Europe, Pussy willows have been adopted as an alternative to the palm leaves used in Palm Sunday celebrations, which were not obtainable in Kashubia. They were blessed by priests on Palm Sunday, following which parishioners whipped each other with the pussy willow branches, saying Wierzba bije, jô nie bijã. Za tidzéń wiôldżi dzéń, za nocë trzë i trzë są Jastrë ('The willow strikes, it's not me who strikes, in a week, on the great day, in three and three nights, there is the Easter').
The blessed by priests pussy willows were treated as sacred charms that could prevent lightning strikes, protect animals and encourage honey production. They were believed to bring health and good fortune to people as well, and it was traditional for one pussy willow bud to be swallowed on Palm Sunday to promote good health.
According to the old tradition, on Easter Monday the Kashub boys chase girls whipping gently their legs with juniper twigs. This is to bring good fortune in love to the chased girls. This was usually accompanied by a boy's chant Dyngus, dyngus – pò dwa jaja, Nie chcã chleba, leno jaja ('Dyngus, dyngus, for two eggs; I don't want bread but eggs'). Sometimes a girl would be whipped when still in her bed. Girls would give boys painted eggs.
In 2005, Kashubian was for the first time made an official subject on the Polish matura exam (roughly equivalent to the English A-Level and French Baccalaureat). Despite an initial uptake of only 23 students, this development was seen as an important step in the official recognition and establishment of the language. Today, in some towns and villages in northern Poland, Kashubian is the second language spoken after Polish, and it is taught in some regional schools.
Since 2005 Kashubian enjoys legal protection in Poland as an official regional language. It is the only tongue in Poland with this status. It was granted by an act of the Polish Parliament on 6 January 2005. Old Kashubian culture has partially survived in architecture and folk crafts such as pottery, plaiting, embroidery, amber-working, sculpturing and glasspainting.
In the 2011 census, 233,000 people in Poland declared their identity as Kashubian, 216,000 declaring it together with Polish and 16,000 as their only national-ethnic identity. Kaszëbskô Jednota is an association of people who have the latter view.
Kashubian cuisine contains many elements from the wider European culinary tradition. Local specialities include:
- Czarnina (Czarwina) – a type of soup made of goose blood
- Brzadowô zupa – a kind of sweet soup with e.g. apples
According to a study published in 2015, by far the most common Y-DNA haplogroup among the Kashubs (n=204) who live in Kashubia, is haplogroup R1a, which is carried by 61.8% of Kashubian males. It is followed in frequency by I1 (13.2%), R1b (9.3%), I2 (4.4%), E1b1b (3.4%), J (2.5%), G (2%) and N1 (1.5%). Other haplogroups are 2%. Another study from 2010 (n=64) discovered similar proportions of most haplogroups (R1a - 68.8%, I1 – 12.5%, R1b - 7.8%, I2 – 3.1%, E1b1b - 3.1%), but found also Q1a in 3.1% of Kashubians. This study reported no significant differences between Kashubians from Poland and other Poles as far as Y chromosome polymorphism is regarded. When it comes to mitochondrial DNA haplogroups, according to a January 2013 study, the most common major mtDNA lineages among the Kashubians, each carried by at least 2.5% of their population, include J1 (12.3%), H1 (11.8%), H* (8.9%), T* (5.9%), T2 (5.4%), U5a (5.4%), U5b (5.4%), U4a (3.9%), H10 (3.9%), H11 (3.0%), H4 (3.0%), K (3.0%), V (3.0%), H2a (2.5%) and W (2.5%). Altogether they account for almost 8/10 of the total Kashubian mtDNA diversity.
In 1858 Polish-Kashubians emigrated to Upper Canada and created the settlement of Wilno, in Renfrew County, Ontario, which still exists. Today Canadian Polish-Kashubians return to Northern Poland in small groups to learn about their heritage.
Kashubian immigrants founded St. Josaphat parish in Chicago's Lincoln Park community in the late 19th century, as well as the parish of Immaculate Heart of Mary in Irving Park, the vicinity of which was dubbed as "Little Cassubia". In the 1870s a fishing village was established in Jones Island in Milwaukee, Wisconsin, by Kashubian immigrants. The settlers however did not hold deeds to the land, and the government of Milwaukee evicted them as squatters in the 1940s, with the area soon after turned into industrial park. The last trace of this Milwaukee fishing village that had been settled by Kashubians on Jones Island is in the name of the smallest park in the city, Kaszube's Park.
