West Prussia in the context of "Weimar Germany"

The Frontier March of Posen–West Prussia (German: Grenzmark Posen-Westpreußen; Polish: Marchia Graniczna Poznańsko-Zachodniopruska) was a province of Prussia that existed from 1920 (de facto) and 1922 (de jure) until its dissolution in 1938. It comprised most of the former territory of West Prussia and parts of the Province of Posen that had remained within Germany following the territorial losses to the Second Polish Republic after the Greater Poland Uprising, and confirmed by the Treaty of Versailles. The province was created in 1922 as part of the Free State of Prussia within Weimar Germany, incorporating three remaining non-contiguous territories of the former provinces of Posen and West Prussia.

Schneidemühl (present-day Piła) served as the provincial capital. From 1934 onwards, the province came under the de facto administration of the Province of Brandenburg, and on 1 October 1938, the territory was officially dissolved by Nazi Germany. Its lands were subsequently incorporated into the neighbouring provinces of Pomerania, Brandenburg and Silesia. Following the end of World War II and the redrawing of borders, the entire area of the former province was incorporated into Poland, lying east of the Oder–Neisse line.

Royal Prussia (Polish: Prusy Królewskie; German: Königlich-Preußen or Preußen Königlichen Anteils, Kashubian: Królewsczé Prësë) or Polish Prussia (Polish: Prusy Polskie; German: Polnisch-Preußen) became a province of the Crown of the Kingdom of Poland, which was annexed following the Second Peace of Thorn (1466) from territory in Pomerelia and western Prussia which had been part of the State of the Teutonic Order. Royal Prussia retained its autonomy, governing itself and maintaining its own laws, customs, and rights.

In 1569, Royal Prussia was fully integrated into the Crown of the Kingdom of Poland and its autonomy was largely abolished. As a result, the Royal Prussian parliament was incorporated into the Sejm of the Polish–Lithuanian Commonwealth. In 1772 and 1793, after the first and second partition of Poland, the former territory of Royal Prussia was annexed by the Kingdom of Prussia and subsequently re-organized into the province of West Prussia. This occurred at the time of the First Partition of Poland, with other parts of the Polish–Lithuanian Commonwealth being annexed by the Russian Empire and Habsburg Austria.

Max Stirner (/ˈstɜːrnər/; German: [ˈʃtɪʁnɐ], 25 October 1806 – 26 June 1856), born Johann Kaspar Schmidt, was a German philosopher, dealing mainly with the Hegelian notion of social alienation and self-consciousness. Stirner is often seen as one of the forerunners of nihilism, existentialism, psychoanalytic theory, postmodernism, individualist anarchism, and egoism.

Born in 1806 in Bayreuth, Bavaria, Stirner's life and work are known largely through a biography by John Henry Mackay. He was orphaned young and raised in West Prussia after his mother's remarriage. Stirner studied at the University of Berlin, where he attended Hegel's lectures. He then moved into teaching and became involved with the Young Hegelians in Berlin. Although he struggled to secure a permanent academic post, Stirner became a fixture in intellectual circles and wrote his most famous work, The Unique and Its Property (German: Der Einzige und sein Eigentum), while supporting himself as a teacher.

The Province of Prussia (German: Provinz Preußen; Lithuanian: Prūsijos provincija; Polish: Prowincja Prusy; Kashubian: Prowincjô Prësë) was a province of the Kingdom of Prussia from 1824 to 1878. The province was established in 1824 from the provinces of West Prussia and East Prussia, and was dissolved in 1878 when the merger was reversed.

Königsberg (present-day Kaliningrad, Russia) was the provincial capital.

The Russian Mennonites (German: Russlandmennoniten [lit. "Russia Mennonites", i.e., Mennonites of or from the Russian Empire]) are a group of Mennonites who are the descendants of Dutch and North German Anabaptists who settled in the Vistula delta in West Prussia for about 250 years and established colonies in the Russian Empire (present-day Ukraine and Russia's Volga region, Orenburg Governorate, and Western Siberia) beginning in 1789. Since the late 19th century, many of them have immigrated to countries which are located throughout the Western Hemisphere. The rest of them were forcibly relocated, so very few of their descendants currently live in the locations of the original colonies. Russian Mennonites are traditionally multilingual but Plautdietsch (Mennonite Low German) is their first language as well as their lingua franca. In 2014, there were several hundred thousand Russian Mennonites: about 200,000 live in Germany, 74,122 live in Mexico, 150,000 in Bolivia, 40,000 live in Paraguay, 10,000 live in Belize, tens of thousands of them live in Canada and the US, and a few thousand live in Argentina, Uruguay, and Brazil.

The term "Russian Mennonite" refers to the country which they resided in before their immigration to the Americas and not to their ethnic heritage. The term "Low-German Mennonites" is also used in order to avoid this conflation.

East Low German (German: ostniederdeutsche Dialekte, ostniederdeutsche Mundarten, Ostniederdeutsch) is a group of Low German dialects spoken in north-eastern Germany as well as by minorities in northern Poland and southern Brazil. Together with West Low German dialects, it forms a dialect continuum of the Low German language. Before 1945, the dialect was spoken along the entire then-German-settled Baltic Coast from Mecklenburg, through Pomerania, West Prussia into certain villages of the East Prussian Klaipėda Region.

East Pomeranian, Central Pomeranian and West Pomeranian should not be confused with the West Slavic Pomeranian language (German: Pomoranisch).

Finckenstein Palace (German: Schloss Finckenstein; Polish: Pałac w Kamieńcu) is a ruined Baroque palace situated in the village of Kamieniec, about 25 mi. (40 km) south of Elbląg, in northern Poland. Formerly part of West Prussia, it was designed by the architect John von Collas and erected in the years 1716–1720 by Prussian Field Marshal, Marquess, and Count Albrecht Konrad Reinhold Finck von Finckenstein. It remained in the possession of the Finck von Finckenstein family until 1782. After that the Counts Dohna-Schlobitten lived in it until 1945. Red Army soldiers set the palace on fire January 22, 1945, during their conquest of Prussia in World War II. The last owner/resident was Alfred (1917–1988), son of Hermann Dohna-Finckenstein (1894–1942).

The palace became famous in 1807, when Napoleon made it his residence from April through June of that year. When he saw the palace for the first time, he said: Enfin un chateau ("Finally, a castle"). The Treaty of Finckenstein between France and Persia was signed here. Here, Napoleon met his Polish mistress Maria Walewska, with whom he lived in the palace. The Hollywood movie Conquest depicted the palace with Greta Garbo and Charles Boyer but was actually filmed in Monterey, California.

Low Prussian (German: Niederpreußisch), sometimes known simply as Prussian (Preußisch), is a moribund dialect of East Low German that developed in East Prussia. Low Prussian was spoken in East and West Prussia and Danzig up to 1945. In Danzig it formed the basis of the particular city dialect of Danzig German. It developed on a Baltic substrate through the influx of Dutch- and Low German-speaking immigrants. It supplanted Old Prussian, which became extinct in the early 18th century.

Simon Dach's poem Anke van Tharaw was written in Low Prussian.
