The Soviet Union (SU or USSR) was a state in Eastern Europe, Central and Northern Asia that existed from 1922 to 1991. It emerged from the so-called Soviet Russia, the successor state of the Russian Empire. The Russian Soviet Republic formed the core of the union and at the same time its largest part, with further constituent republics added. Their number varied over time and was related to the occupation of other countries (Estonia, Latvia, Lithuania), Soviet republics that existed only for a short time (Karelo-Finlandia) or the division or merger of Soviet republics. In addition, there were numerous autonomous republics or other territorial units with an autonomy status that was essentially limited to linguistic autonomy for minorities.
Before its formal dissolution, the USSR consisted of 15 Soviet republics with a population of approximately 290 million people. At around 22.4 million km², it was the largest territorial state in the world at the time. The Soviet Union was a socialist soviet republic with a one-party system and an absence of separation of powers.
The city on the Volga was called Tsaritsyn until 1925, then Stalingrad until 1961. It is internationally known because of the Battle of Stalingrad in World War II, in which the Wehrmacht and its allies were devastatingly defeated by the Red Army in the winter of 1942/43, and which is considered a psychological turning point in the war. In the framework of de-Stalinization, the city was renamed Volgograd in 1961.
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).
Marienburg (Polish: Malbork) is a city in the Polish voivodeship of Pomerania (Polish: Pomorskie). It is located in the north of Poland, about 50 km southeast of Gdańsk/Gdansk. Marienburg lies on the Nogat River and is populated by just under 39,000 people.
