Silesia (Polish: Śląsk, Czech: Slezsko) is a historical landscape, which today is mainly located in the extreme southwest of Poland, but in parts also on the territory of Germany and the Czech Republic. By far the most significant river is the Oder. To the south, Silesia is bordered mainly by the Sudeten and Beskid mountain ranges. Today, almost 8 million people live in Silesia. The largest cities in the region are Wrocław, Opole and Katowice. Before 1945, most of the region was part of Prussia for two hundred years, and before the Silesian Wars (from 1740) it was part of the Habsburg Empire for almost as many years. Silesia is classified into Upper and Lower Silesia.

Pomerania is a region in northeastern Germany (Vorpommern) and northwestern Poland (Hinterpommern/Pomorze Tylne). The name is derived from the West Slavic 'by the sea' - 'po more/morze'. After the Thirty Years' War (Peace of Westphalia in 1648), Western Pomerania initially became Swedish, and Western Pomerania fell to Brandenburg, which was able to acquire further parts of Western Pomerania in 1720. It was not until 1815 that the entire region belonged to the Kingdom of Prussia as the Province of Pomerania. The province existed until the end of World War II, its capital was Szczecin (today Polish: Stettin).

West Prussia is a historical region in present-day northern Poland. The region fell to Prussia as a result of the first partition of Poland-Lithuania in 1772 and received its name from the province of the same name formed by Frederick II in 1775, which also included parts of the historical landscapes of Greater Poland, Pomerania, Pomesania and Kulmerland. The Prussian province lasted in changing borders until the early 20th century. After World War I, parts fell to the Second Polish Republic, founded in 1918. The largest cities in West Prussia include Gdansk (Polish: Gdańsk, today Pomeranian Voivodeship), Elbląg (Polish: Elbląg, today Warmia-Masuria Voivodeship), and Thorn (Polish: Toruń, today Kujawsko-Pomeranian Voivodeship).

Ostpreußen ist der Name der ehemaligen, bis 1945 bestehenden östlichsten preußischen Provinz, deren Ausdehnung (ungeachtet historisch leicht wechselnder Grenzverläufe) ungefähr der historischen Landschaft Preußen entspricht. Die Bezeichnung kam erst in der zweiten Hälfte des 18. Jahrhunderts in Gebrauch, als neben dem 1701 zum Königreich erhobenen Herzogtum Preußen mit seiner Hauptstadt Königsberg weitere, zuvor polnische Gebiete im Westen (beispielsweise das sog. Preußen Königlichen Anteils mit dem Ermland und Pommerellen) zu Brandenburg-Preußen kamen und die neue Provinz Westpreußen bildeten.
Heutzutage gehört das Gebiet der ehemaligen preußischen Provinz überwiegend zu Russland (Oblast Kaliningrad) und Polen (Woiwodschaft Ermland-Masuren). Das ehemalige sog. Memelland (auch Memelgebiet, lit. Klaipėdos kraštas) kam erstmals 1920 und erneut ab 1945 zu Litauen.

The term "Bohemian lands" is used to refer to the historical lands of Bohemia, Moravia and Austrian Silesia. It is not to be confused with the "Lands of the Bohemian Crown", which, after initial Luxembourgian rule, constituted one of the three parts of the Central European Habsburg Empire since the 16th century, and which, in addition to Silesia, at times included also the Margraviates of Upper Lusatia and Lower Lusatia.
