West Prussia genealogy relates to the study of family history research in the former province of the Kingdom of Prussia, known as Westpreußen in German. The territory existed from 1772 through 1829, and from 1878 until 1920 as part of the German Empire. Between 1829 and 1878, it united with East Prussia as the province of Prussia.
West Prussia was dissolved in 1920, following World War I, dividing up into other Prussian provinces. After World War II, it became part of modern-day Poland.
The capital of West Prussia alternated between Marienwerder (today Kwidzyn, Poland) and Danzig (today Gdańsk, Poland) at various points of its history.
Those who lived in West Prussia were a mixture of ethnicities: German, Polish, Dutch, Kashubians, Mennonites, and Jews among them.

History of West Prussia

A Slavic people lived around the Baltic going back several centuries. They were known as Preussen and were kin to the Lithuanians and Latvians.[1] Christianity was brought to the region in the 1200s by the Teutonic Order and had an important role in its development. German peasants came to farm the land and by the mid-14th century, the majority of the population was German.[1]
The old territory of West Prussia was part of the Kingdom of Poland from 1466 to 1701. Friedrich I crowned himself King in 1701, formally beginning the Kingdom of Prussia. The first partition of Poland in 1772 led to the birth of West Prussia as a province.
West Prussia briefly lost Danzig during the Napoleonic Wars, as well as territory around Thorn and Culm, but it was returned to the province after the conflict in the Congress of Vienna (1814-1815).
The population of West Prussia was about 700,000 in 1831 with 50% identifying as Polish, 47% German, and 3% Jews.[2] Religiously, it was about an even split between Protestant and Catholic with a smaller population of Jews and Mennonites.[2]
West Prussia disappeared from the map in 1920, as it dissolved into other Prussian provinces. The old territory of West Prussia became part of Poland after World War II.
Geography of West Prussia

The land of West Prussia is situated along the Baltic Sea, with the Vistula running through the heart of its territory and several other waterways connecting its various towns. The largest settlements were along the Vistula, Nogat or Elbag rivers.[3]
It is made up of vast swaths of countryside, a scenic region known as the "Kashubian Switzerland", and extensive forest areas including the Tuchola Forest.[3] In the south, West Prussia consisted of hills and lakes.
Its seaports, notably centered around Danzig (Gdansk), were vital to the region and have played a part in migration and trade over the centuries. Danzig itself reached its peak as one of the most prosperous ports on the Baltic during the Renaissance period (15th-16th century).[4]
Administrative districts
West Prussia was made up of two administrative regions (Regierungsbezirke): Danzig and Marienwerder. These were divided into smaller Kreise (districts):
Danzig | Marienwerder |
---|---|
Berent | Briesen |
Danziger Höhe | Culm |
Danziger Niederung | Deutsch Krone |
Stadtkreis Danzig | Flatow |
Dirschau | Graudenz (Land & Stadt) |
Elbing (Land & Stadt) | Konitz |

Marienburg | Marienwerder |
Neustadt | Rosenberg |
Preußisch Stargard | Schlochau |
Putzig | Schwetz |

The Kreis can be useful for genealogical research. Determine the Kreis for the town or village of interest at Meyers Gazetteer. Look for locations with "Westpreussen" beside them. Check the Ecclesiastical tab for the Catholic parish and Protestant parish, when it is known.

- Pomorskie
